Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Summary of Significant Accounting Policies
	Principles of Consolidation and Basis of Presentation
	The Consolidated Financial Statements included in this report have been prepared by management of The Boeing Company (herein referred to as “Boeing,” the “Company,” “we,” “us,” or “our”). These statements include the accounts of all majority-owned subsidiaries and variable interest entities that are required to be consolidated. All significant intercompany accounts and transactions have been eliminated. Segment data for all years have been adjusted to reflect a realignment of certain programs from the Boeing Military Aircraft (BMA) segment to the Global Services & Support (GS&S) segment and the combination of Other segment with Unallocated items and eliminations. See Note 21.
	Standards Issued and Not Yet Implemented
	In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers. The new standard is effective for reporting periods beginning after December 15, 2016 and early adoption is not permitted. The comprehensive new standard will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. Adoption of the new rules could affect the timing of revenue recognition for certain transactions. The guidance permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. For Boeing the new standard will be effective January 1, 2017 and the Company is currently evaluating the impacts of adoption and the implementation approach to be used.
	Use of Estimates
	Management makes assumptions and estimates to prepare financial statements in conformity with accounting principles generally accepted in the United States of America. Those assumptions and estimates directly affect the amounts reported in the Consolidated Financial Statements. Significant estimates for which changes in the near term are considered reasonably possible and that may have a material impact on the financial statements are disclosed in these Notes to the Consolidated Financial Statements.
	Operating Cycle
	For classification of certain current assets and liabilities, we use the duration of the related contract or program as our operating cycle, which is generally longer than one year.
	Revenue and Related Cost Recognition
	Contract Accounting Contract accounting is used for development and production activities predominantly by Defense, Space & Security (BDS). The majority of business conducted by BDS is performed under contracts with the U.S. government and other customers that extend over several years. Contract accounting involves a judgmental process of estimating total sales and costs for each contract resulting in the development of estimated cost of sales percentages. For each contract, the amount reported as cost of sales is determined by applying the estimated cost of sales percentage to the amount of revenue recognized. When the current estimates of total sales and costs for a contract indicate a loss, a provision for the entire loss on the contract is recognized.
	Changes in estimated revenues, cost of sales and the related effect on operating income are recognized using a cumulative catch-up adjustment which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a contract’s percent complete. In 2014, 2013 and 2012 net favorable cumulative catch-up adjustments, including reach-forward losses, across all contracts increased Earnings from operations by $100, $242 and $379, respectively and diluted EPS by $0.10, $0.23 and $0.33, respectively. Significant adjustments during the three years ended December 31, 2014 included a reach-forward loss of $425 on the USAF KC-46A Tanker contract recorded during 2014.
	We combine contracts for accounting purposes when they are negotiated as a package with an overall profit margin objective. These essentially represent an agreement to do a single project for a single customer, involve interrelated construction activities with substantial common costs, and are performed concurrently or sequentially. When a group of contracts is combined, revenue and profit are earned uniformly over the performance of the combined contracts. Similarly, we may segment a single contract or group of contracts when a clear economic decision has been made during contract negotiations that would produce different rates of profitability for each element or phase of the contract.
	Sales related to fixed-price contracts are recognized as deliveries are made, except for certain fixed-price contracts that require substantial performance over an extended period before deliveries begin, for which sales are recorded based on the attainment of performance milestones. Sales related to contracts in which we are reimbursed for costs incurred plus an agreed upon profit are recorded as costs are incurred. The Federal Acquisition Regulations provide guidance on the types of cost that will be reimbursed in establishing contract price. Contracts may contain provisions to earn incentive and award fees if specified targets are achieved. Incentive and award fees that can be reasonably estimated and are probable are recorded over the performance period of the contract. Incentive and award fees that cannot be reasonably estimated are recorded when awarded.
	Program Accounting Our Commercial Airplanes segment predominantly uses program accounting to account for cost of sales related to its programs. Program accounting is applicable to products manufactured for delivery under production-type contracts where profitability is realized over multiple contracts and years. Under program accounting, inventoriable production costs, program tooling and other non-recurring costs, and warranty costs are accumulated and charged to cost of sales by program instead of by individual units or contracts. A program consists of the estimated number of units (accounting quantity) of a product to be produced in a continuing, long-term production effort for delivery under existing and anticipated contracts. The determination of the accounting quantity is limited by the ability to make reasonably dependable estimates of the revenue and cost of existing and anticipated contracts. To establish the relationship of sales to cost of sales, program accounting requires estimates of (a) the number of units to be produced and sold in a program, (b) the period over which the units can reasonably be expected to be produced, and (c) the units’ expected sales prices, production costs, program tooling and other non-recurring costs, and routine warranty costs for the total program.
	We recognize sales for commercial airplane deliveries as each unit is completed and accepted by the customer. Sales recognized represent the price negotiated with the customer, adjusted by an escalation formula as specified in the customer agreement. The amount reported as cost of sales is determined by applying the estimated cost of sales percentage for the total remaining program to the amount of sales recognized for airplanes delivered and accepted by the customer. Changes in estimated revenues, cost of sales and the related effects on program margins are recognized prospectively except in cases where the program is determined to have a reach-forward loss in which case the loss is recognized in the current period. See Note 11.
	Concession Sharing Arrangements We account for sales concessions to our customers in consideration of their purchase of products and services as a reduction to revenue when the related products and services are delivered. The sales concessions incurred may be partially reimbursed by certain suppliers in accordance with concession sharing arrangements. We record these reimbursements, which are presumed to represent reductions in the price of the vendor’s products or services, as a reduction in Cost of products.
	Spare Parts Revenue We recognize sales of spare parts upon delivery and the amount reported as cost of sales is recorded at average cost.
	Service Revenue Service revenue is recognized when the service is performed with the exception of U.S. government service agreements, which are accounted for using contract accounting. Service activities primarily include: support agreements associated with military aircraft and helicopter contracts, ongoing maintenance of International Space Station, and technical and flight operation services for commercial aircraft. Service revenue and associated cost of sales from pay-in-advance subscription fees are deferred and recognized as services are rendered.
	Financial Services Revenue We record financial services revenue associated with sales-type/finance leases, operating leases, and notes receivable.
	Lease and financing revenue arrangements are included in Sales of services on the Consolidated Statements of Operations. For sales-type/finance leases, we record an asset at lease inception. This asset is recorded at the aggregate future minimum lease payments, estimated residual value of the leased equipment, and deferred incremental direct costs less unearned income. Income is recognized over the life of the lease to approximate a level rate of return on the net investment. Residual values, which are reviewed periodically, represent the estimated amount we expect to receive at lease termination from the disposition of the leased equipment. Actual residual values realized could differ from these estimates. Declines in estimated residual value that are deemed other-than-temporary are recognized in the period in which the declines occur.
	For operating leases, revenue on leased aircraft and equipment is recorded on a straight-line basis over the term of the lease. Operating lease assets, included in Customer financing, are recorded at cost and depreciated over the period that we project we will hold the asset to an estimated residual value, using the straight-line method. We periodically review our estimates of residual value and recognize forecasted changes by prospectively adjusting depreciation expense.
	For notes receivable, notes are recorded net of any unamortized discounts and deferred incremental direct costs. Interest income and amortization of any discounts are recorded ratably over the related term of the note.
	Reinsurance Revenue Our wholly-owned insurance subsidiary, Astro Ltd., participates in a reinsurance pool for workers’ compensation. The member agreements and practices of the reinsurance pool minimize any participating members’ individual risk. Reinsurance revenues were $135, $160 and $129 during 2014, 2013 and 2012, respectively. Reinsurance costs related to premiums and claims paid to the reinsurance pool were $144, $147 and $128 during 2014, 2013 and 2012, respectively. Revenues and costs are presented net in Cost of sales in the Consolidated Statements of Operations.
	Fleet Support
	We provide assistance and services to facilitate efficient and safe aircraft operation to the operators of all our commercial airplane models. Collectively known as fleet support services, these activities and services include flight and maintenance training, field service support, engineering services, and technical data and documents. Fleet support activity begins prior to aircraft delivery as the customer receives training, manuals, and technical consulting support. This activity continues throughout the aircraft’s operational life. Services provided after delivery include field service support, consulting on maintenance, repair, and operational issues brought forth by the customer or regulators, updating manuals and engineering data, and the issuance of service bulletins that impact the entire model’s fleet. Field service support involves our personnel located at customer facilities providing and coordinating fleet support activities and requests. The costs for fleet support are expensed as incurred as Cost of services.
	Research and Development
	Research and development includes costs incurred for experimentation, design, and testing, as well as bid and proposal efforts related to government products and services which are expensed as incurred unless the costs are related to certain contractual arrangements with customers. Costs that are incurred pursuant to such contractual arrangements are recorded over the period that revenue is recognized, consistent with our contract accounting policy. We have certain research and development arrangements that meet the requirement for best efforts research and development accounting. Accordingly, the amounts funded by the customer are recognized as an offset to our research and development expense rather than as contract revenues. Research and development expense included bid and proposal costs of $289, $285 and $326 in 2014, 2013 and 2012, respectively.
	We have established cost sharing arrangements with some suppliers for the 787 program. Our cost sharing arrangements state that the supplier contributions are for reimbursements of costs we incur for experimentation, basic design, and testing activities during the 787 development. In each arrangement, we retain substantial rights to the 787 part or component covered by the arrangement. The amounts received from these cost sharing arrangements are recorded as a reduction to research and development expenses since we have no obligation to refund any amounts received per the arrangements regardless of the outcome of the development efforts. Specifically, under the terms of each agreement, payments received from suppliers for their share of the costs are typically based on milestones and are recognized as earned when we achieve the milestone events and no ongoing obligation on our part exists. In the event we receive a milestone payment prior to the completion of the milestone, the amount is classified in Accrued liabilities until earned.
	Share-Based Compensation
	We provide various forms of share-based compensation to our employees. For awards settled in shares, we measure compensation expense based on the grant-date fair value net of estimated forfeitures. For awards settled in cash, or that may be settled in cash, we measure compensation expense based on the fair value at each reporting date net of estimated forfeitures. The expense is recognized over the requisite service period, which is generally the vesting period of the award.
	Income Taxes
	Provisions for federal, state, and non-U.S. income taxes are calculated on reported Earnings before income taxes based on current tax law and also include, in the current period, the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provisions differ from the amounts currently receivable or payable because certain items of income and expense are recognized in different time periods for financial reporting purposes than for income tax purposes. Significant judgment is required in determining income tax provisions and evaluating tax positions.
	The accounting for uncertainty in income taxes requires a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. We record a liability for the difference between the benefit recognized and measured for financial statement purposes and the tax position taken or expected to be taken on our tax return. To the extent that our assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. Tax-related interest and penalties are classified as a component of Income tax expense.
	Postretirement Plans
	The majority of our employees are earning benefits under defined benefit pension plans. In 2014, we announced changes to our retirement plans whereby nonunion and the majority of union employees currently participating in defined benefit pension plans will transition in 2016 to a company-funded defined contribution retirement savings plan. We also provide postretirement benefit plans other than pensions, consisting principally of health care coverage to eligible retirees and qualifying dependents. Benefits under the pension and other postretirement benefit plans are generally based on age at retirement and years of service and, for some pension plans, benefits are also based on the employee’s annual earnings. The net periodic cost of our pension and other postretirement plans is determined using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate, the long-term rate of asset return, and medical trend (rate of growth for medical costs). A portion of net periodic pension and other postretirement income or expense is not recognized in net earnings in the year incurred because it is allocated to production as product costs, and reflected in inventory at the end of a reporting period. Actuarial gains and losses, which occur when actual experience differs from actuarial assumptions, are reflected in Shareholders’ equity (net of taxes). If actuarial gains and losses exceed ten percent of the greater of plan assets or plan liabilities we amortize them over the average future service period of employees. The funded status of our pension and postretirement plans is reflected on the Consolidated Statements of Financial Position.
	Postemployment Plans
	We record a liability for postemployment benefits, such as severance or job training, when payment is probable, the amount is reasonably estimable, and the obligation relates to rights that have vested or accumulated.
	Environmental Remediation
	We are subject to federal and state requirements for protection of the environment, including those for discharge of hazardous materials and remediation of contaminated sites. We routinely assess, based on in-depth studies, expert analyses and legal reviews, our contingencies, obligations, and commitments for remediation of contaminated sites, including assessments of ranges and probabilities of recoveries from other responsible parties and/or insurance carriers. Our policy is to accrue and charge to current expense identified exposures related to environmental remediation sites when it is probable that a liability has been incurred and the amount can be reasonably estimated. The amount of the liability is based on our best estimate or the low end of a range of reasonably possible exposure for investigation, cleanup, and monitoring costs to be incurred. Estimated remediation costs are not discounted to present value as the timing of payments cannot be reasonably estimated. We may be able to recover a portion of the remediation costs from insurers or other third parties. Such recoveries are recorded when realization of the claim for recovery is deemed probable.
	Cash and Cash Equivalents
	Cash and cash equivalents consist of highly liquid instruments, such as commercial paper, time deposits, and other money market instruments, which have original maturities of three months or less. We aggregate our cash balances by bank where conditions for right of set-off are met, and reclassify any negative balances, consisting mainly of uncleared checks, to Accounts payable. Negative balances reclassified to Accounts payable were $241 and $108 at December 31, 2014 and 2013.
	Inventories
	Inventoried costs on commercial aircraft programs and long-term contracts include direct engineering, production and tooling and other non-recurring costs, and applicable overhead, which includes fringe benefits, production related indirect and plant management salaries and plant services, not in excess of estimated net realizable value. To the extent a material amount of such costs are related to an abnormal event or are fixed costs not appropriately attributable to our programs or contracts, they are expensed in the current period rather than inventoried. Inventoried costs include amounts relating to programs and contracts with long-term production cycles, a portion of which is not expected to be realized within one year. Included in inventory for federal government contracts is an allocation of allowable costs related to manufacturing process reengineering.
	Commercial aircraft programs inventory includes deferred production costs and supplier advances. Deferred production costs represent actual costs incurred for production of early units that exceed the estimated average cost of all units in the program accounting quantity. Higher production costs are experienced at the beginning of a new or derivative airplane program. Units produced early in a program require substantially more effort (labor and other resources) than units produced later in a program because of volume efficiencies and the effects of learning. We expect that these deferred costs will be fully recovered when all units included in the accounting quantity are delivered as the expected unit cost for later deliveries is below the estimated average cost of all units in the program. Supplier advances represent payments for parts we have contracted to receive from suppliers in the future. As parts are received, supplier advances are amortized to work in process.
	The determination of net realizable value of long-term contract costs is based upon quarterly reviews that estimate costs to be incurred to complete all contract requirements. When actual contract costs and the estimate to complete exceed total estimated contract revenues, a loss provision is recorded. The determination of net realizable value of commercial aircraft program costs is based upon quarterly program reviews that estimate revenue and cost to be incurred to complete the program accounting quantity. When estimated costs to complete exceed estimated program revenues to go, a program loss provision is recorded in the current period for the estimated loss on all undelivered units in the accounting quantity.
	Used aircraft purchased by the Commercial Airplanes segment and general stock materials are stated at cost not in excess of net realizable value. See ‘Aircraft Valuation’ within this Note for a discussion of our valuation of used aircraft. Spare parts inventory is stated at lower of average unit cost or market. We review our commercial spare parts and general stock materials quarterly to identify impaired inventory, including excess or obsolete inventory, based on historical sales trends, expected production usage, and the size and age of the aircraft fleet using the part. Impaired inventories are charged to Cost of products in the period the impairment occurs.
	Included in inventory for commercial aircraft programs are amounts paid or credited in cash, or other consideration to certain airline customers, that are referred to as early issue sales consideration. Early issue sales consideration is recognized as a reduction to revenue when the delivery of the aircraft under contract occurs. If an airline customer does not perform and take delivery of the contracted aircraft, we believe that we would have the ability to recover amounts paid. However, to the extent early issue sales consideration exceeds advances and is not considered to be otherwise recoverable, it would be written off in the current period.
	We net advances and progress billings on long-term contracts against inventory in the Consolidated Statements of Financial Position. Advances and progress billings in excess of related inventory are reported in Advances and billings in excess of related costs.
	Precontract Costs
	We may, from time to time, incur costs in excess of the amounts required for existing contracts. If we determine the costs are probable of recovery from future orders, then we capitalize the precontract costs we incur, excluding start-up costs which are expensed as incurred. Capitalized precontract costs are included in Inventories, net of advances and progress billings, in the accompanying Consolidated Statements of Financial Position. Should future orders not materialize or we determine the costs are no longer probable of recovery, the capitalized costs would be written off.
	Property, Plant and Equipment
	Property, plant and equipment are recorded at cost, including applicable construction-period interest, less accumulated depreciation and are depreciated principally over the following estimated useful lives: new buildings and land improvements, from 10 to 40 years; and new machinery and equipment, from 3 to 20 years. The principal methods of depreciation are as follows: buildings and land improvements, 150% declining balance; and machinery and equipment, sum-of-the-years’ digits. Capitalized internal use software is included in Other assets and amortized using the straight line method over 5 years. We periodically evaluate the appropriateness of remaining depreciable lives assigned to long-lived assets, including assets that may be subject to a management plan for disposition.
	Long-lived assets held for sale are stated at the lower of cost or fair value less cost to sell. Long-lived assets held for use are subject to an impairment assessment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.
	Asset Retirement Obligations
	We record all known asset retirement obligations for which the liability’s fair value can be reasonably estimated, including certain asbestos removal, asset decommissioning and contractual lease restoration obligations. Recorded amounts are not material.
	We also have known conditional asset retirement obligations, such as certain asbestos remediation and asset decommissioning activities to be performed in the future, that are not reasonably estimable due to insufficient information about the timing and method of settlement of the obligation. Accordingly, these obligations have not been recorded in the Consolidated Financial Statements. A liability for these obligations will be recorded in the period when sufficient information regarding timing and method of settlement becomes available to make a reasonable estimate of the liability’s fair value. In addition, there may be conditional asset retirement obligations that we have not yet discovered (e.g. asbestos may exist in certain buildings but we have not become aware of it through the normal course of business), and therefore, these obligations also have not been included in the Consolidated Financial Statements.
	Goodwill and Other Acquired Intangibles
	Goodwill and other acquired intangible assets with indefinite lives are not amortized, but are tested for impairment annually and when an event occurs or circumstances change such that it is more likely than not that an impairment may exist. Our annual testing date is April 1.
	We test goodwill for impairment by performing a qualitative assessment or using a two-step impairment process. If we choose to perform a qualitative assessment and determine it is more likely than not that the carrying value of the net assets is more than the fair value of the related operations, the two-step impairment process is then performed; otherwise, no further testing is required. For operations where the two-step impairment process is used, we first compare the carrying value of net assets to the fair value of the related operations. If the fair value is determined to be less than carrying value, a second step is performed to compute the amount of the impairment. In this process, a fair value for goodwill is estimated, based in part on the fair value of the operations, and is compared to its carrying value. The shortfall of the fair value below carrying value represents the amount of goodwill impairment.
	Indefinite-lived intangibles consist of brand and trade names acquired in business combinations. We test these intangibles for impairment by comparing their carrying value to current projections of discounted cash flows attributable to the brand and trade names. Any excess carrying value over the amount of discounted cash flows represents the amount of the impairment.
	Our finite-lived acquired intangible assets are amortized on a straight-line basis over their estimated useful lives as follows: developed technology, from 5 to 14 years; product know-how, from 5 to 30 years; customer base, from 3 to 19 years; distribution rights, from 5 to 27 years; and other, from 3 to 32 years. We evaluate the potential impairment of finite-lived acquired intangible assets whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.
	Investments
	Time deposits are held-to-maturity investments that are carried at cost.
The equity method of accounting is used to account for investments for which we have the ability to exercise significant influence, but not control, over an investee. Significant influence is generally deemed to exist if we have an ownership interest in the voting stock of an investee of between 20% and 50%.
We classify investment income and loss on our Consolidated Statements of Operations based on whether the investment is operating or non-operating in nature. Operating investments align strategically and are integrated with our operations. Earnings from operating investments, including our share of income or loss from equity method investments, dividend income from certain cost method investments, and any impairments or gain/loss on the disposition of these investments, are recorded in Income from operating investments, net. Non-operating investments are those we hold for non-strategic purposes. Earnings from non-operating investments, including interest and dividends on marketable securities, and any impairments or gain/loss on the disposition of these investments are recorded in Other income/(expense), net.
Derivatives
All derivative instruments are recognized in the financial statements and measured at fair value regardless of the purpose or intent of holding them. We use derivative instruments to principally manage a variety of market risks. For derivatives designated as hedges of the exposure to changes in fair value of the recognized asset or liability or a firm commitment (referred to as fair value hedges), the gain or loss is recognized in earnings in the period of change together with the offsetting loss or gain on the hedged item attributable to the risk being hedged. The effect of that accounting is to include in earnings the extent to which the hedge is not effective in achieving offsetting changes in fair value. For our cash flow hedges, the effective portion of the derivative’s gain or loss is initially reported in comprehensive income and is subsequently reclassified into earnings in the same period or periods during which the hedged forecasted transaction affects earnings. The ineffective portion of the gain or loss of a cash flow hedge is reported in earnings immediately. We also hold certain instruments for economic purposes that are not designated for hedge accounting treatment. For these derivative instruments, the changes in their fair value are also recorded in earnings immediately.
Aircraft Valuation
Used aircraft under trade-in commitments and aircraft under repurchase commitments In conjunction with signing a definitive agreement for the sale of new aircraft (Sale Aircraft), we have entered into trade-in commitments with certain customers that give them the right to trade in used aircraft at a specified price upon the purchase of Sale Aircraft. Additionally, we have entered into contingent repurchase commitments with certain customers wherein we agree to repurchase the Sale Aircraft at a specified price, generally 10 to 15 years after delivery of the Sale Aircraft. Our repurchase of the Sale Aircraft is contingent upon a future, mutually acceptable agreement for the sale of additional new aircraft. If we execute an agreement for the sale of additional new aircraft, and if the customer exercises its right to sell the Sale Aircraft to us, a contingent repurchase commitment would become a trade-in commitment. Our historical experience is that contingent repurchase commitments infrequently become trade-in commitments.
Exposure related to trade-in commitments may take the form of:
-1	adjustments to revenue for the difference between the contractual trade-in price in the definitive agreement and our best estimate of the fair value of the trade-in aircraft as of the date of such agreement, which would be recognized upon delivery of the Sale Aircraft, and/or
-2	charges to cost of products for adverse changes in the fair value of trade-in aircraft that occur subsequent to signing of a definitive agreement for Sale Aircraft but prior to the purchase of the used trade-in aircraft. Estimates based on current aircraft values would be included in Accrued liabilities.
The fair value of trade-in aircraft is determined using aircraft-specific data such as model, age and condition, market conditions for specific aircraft and similar models, and multiple valuation sources. This process uses our assessment of the market for each trade-in aircraft, which in most instances begins years before the return of the aircraft. There are several possible markets in which we continually pursue opportunities to place used aircraft. These markets include, but are not limited to, the resale market, which could potentially include the cost of long-term storage; the leasing market, with the potential for refurbishment costs to meet the leasing customer’s requirements; or the scrap market. Trade-in aircraft valuation varies significantly depending on which market we determine is most likely for each aircraft. On a quarterly basis, we update our valuation analysis based on the actual activities associated with placing each aircraft into a market. This quarterly valuation process yields results that are typically lower than residual value estimates by independent sources and tends to more accurately reflect results upon the actual placement of the aircraft.
Used aircraft acquired by the Commercial Airplanes segment are included in Inventories at the lower of cost or market as it is our intent to sell these assets. To mitigate costs and enhance marketability, aircraft may be placed on operating lease. While on operating lease, the assets are included in Customer financing.
Customer financing Customer financing includes operating lease equipment, notes receivable, and sales-type/finance leases. Sales-type/finance leases are treated as receivables, and allowances for losses are established as necessary.
We assess the fair value of the assets we own, including equipment under operating leases, assets held for sale or re-lease, and collateral underlying receivables, to determine if their fair values are less than the related assets’ carrying values. Differences between carrying values and fair values of sales-type/finance leases and notes and other receivables, as determined by collateral value, are considered in determining the allowance for losses on receivables.
We use a median calculated from published collateral values from multiple third-party aircraft value publications based on the type and age of the aircraft to determine the fair value of aircraft. Under certain circumstances, we apply judgment based on the attributes of the specific aircraft or equipment, usually when the features or use of the aircraft vary significantly from the more generic aircraft attributes covered by outside publications.
Impairment review for assets under operating leases and held for sale or re-lease We evaluate for impairment assets under operating lease or assets held for sale or re-lease when events or changes in circumstances indicate that the expected undiscounted cash flow from the asset may be less than the carrying value. We use various assumptions when determining the expected undiscounted cash flow, including our intentions for how long we will hold an asset subject to operating lease before it is sold, the expected future lease rates, lease terms, residual value of the asset, periods in which the asset may be held in preparation for a follow-on lease, maintenance costs, remarketing costs and the remaining economic life of the asset. We record assets held for sale at the lower of carrying value or fair value less costs to sell.
When we determine that impairment is indicated for an asset, the amount of impairment expense recorded is the excess of the carrying value over the fair value of the asset.
Allowance for losses on customer financing receivables We record the potential impairment of customer financing receivables in a valuation account, the balance of which is an accounting estimate of probable but unconfirmed losses. The allowance for losses on receivables relates to two components of receivables: (a) receivables that are evaluated individually for impairment and (b) all other receivables.
We determine a receivable is impaired when, based on current information and events, it is probable that we will be unable to collect amounts due according to the original contractual terms of the receivable agreement, without regard to any subsequent restructurings. Factors considered in assessing collectability include, but are not limited to, a customer’s extended delinquency, requests for restructuring and filings for bankruptcy. We determine a specific impairment allowance based on the difference between the carrying value of the receivable and the estimated fair value of the related collateral we would expect to realize.
We review the adequacy of the allowance attributable to the remaining receivables (after excluding receivables subject to a specific impairment allowance) by assessing both the collateral exposure and the applicable cumulative default rate. Collateral exposure for a particular receivable is the excess of the carrying value of the receivable over the fair value of the related collateral. A receivable with an estimated fair value in excess of the carrying value is considered to have no collateral exposure. The applicable cumulative default rate is determined using two components: customer credit ratings and weighted average remaining contract term. Internally assigned credit ratings, our credit quality indicator, are determined for each customer in the portfolio. Those ratings are updated based upon public information and information obtained directly from our customers.
We have entered into agreements with certain customers that would entitle us to look beyond the specific collateral underlying the receivable for purposes of determining the collateral exposure as described above. Should the proceeds from the sale of the underlying collateral asset resulting from a default condition be insufficient to cover the carrying value of our receivable (creating a shortfall condition), these agreements would, for example, permit us to take the actions necessary to sell or retain certain other assets in which the customer has an equity interest and use the proceeds to cover the shortfall.
Each quarter we review customer credit ratings, published historical credit default rates for different rating categories, and multiple third-party aircraft value publications as a basis to validate the reasonableness of the allowance for losses on receivables. There can be no assurance that actual results will not differ from estimates or that the consideration of these factors in the future will not result in an increase or decrease to the allowance for losses on receivables.
Warranties
In conjunction with certain product sales, we provide warranties that cover factors such as non-conformance to specifications and defects in material and design. The majority of our warranties are issued by our Commercial Airplanes segment. Generally, aircraft sales are accompanied by a three to four-year standard warranty for systems, accessories, equipment, parts, and software manufactured by us or manufactured to certain standards under our authorization. These warranties are included in the programs’ estimate at completion. On occasion we have made commitments beyond the standard warranty obligation to correct fleet-wide major issues of a particular model, resulting in additional accrued warranty expense. Warranties issued by our BDS segments principally relate to sales of military aircraft and weapons hardware and are included in the contract cost estimates. These sales are generally accompanied by a six to twelve-month warranty period and cover systems, accessories, equipment, parts, and software manufactured by us to certain contractual specifications. Estimated costs related to standard warranties are recorded in the period in which the related product sales occur. The warranty liability recorded at each balance sheet date reflects the estimated number of months of warranty coverage outstanding for products delivered times the average of historical monthly warranty payments, as well as additional amounts for certain major warranty issues that exceed a normal claims level. Estimated costs of these additional warranty issues are considered changes to the initial liability estimate.
We provide guarantees to certain commercial airplane customers which include compensation provisions for failure to meet specified aircraft performance targets. We account for these performance guarantees as warranties. The estimated liability for these warranties is based on known and anticipated operational characteristics and forecasted customer operation of the aircraft relative to contractually specified performance targets, and anticipated settlements when contractual remedies are not specified. Estimated payments are recorded as a reduction of revenue at delivery of the related aircraft. We have agreements that require certain suppliers to compensate us for amounts paid to customers for failure of supplied equipment to meet specified performance targets. Claims against suppliers under these agreements are included in Inventories and recorded as a reduction in Cost of products at delivery of the related aircraft. These performance warranties and claims against suppliers are included in the programs’ estimate at completion.
Supplier Penalties
We record an accrual for supplier penalties when an event occurs that makes it probable that a supplier penalty will be incurred and the amount is reasonably estimable. Until an event occurs, we fully anticipate accepting all products procured under production-related contracts.
Guarantees
We record a liability in Accrued liabilities for the fair value of guarantees that are issued or modified after December 31, 2002. For a residual value guarantee where we received a cash premium, the liability is equal to the cash premium received at the guarantee’s inception. For credit guarantees, the liability is equal to the present value of the expected loss. We determine the expected loss by multiplying the creditor’s default rate by the guarantee amount reduced by the expected recovery, if applicable, for each future period the credit guarantee will be outstanding. If at inception of a guarantee, we determine there is a probable related contingent loss, we will recognize a liability for the greater of (a) the fair value of the guarantee as described above or (b) the probable contingent loss amount.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share
	Basic and diluted earnings per share are computed using the two-class method, which is an earnings allocation method that determines earnings per share for common shares and participating securities. The undistributed earnings are allocated between common shares and participating securities as if all earnings had been distributed during the period. Participating securities and common shares have equal rights to undistributed earnings.
	Basic earnings per share is calculated by taking net earnings, less earnings available to participating securities, divided by the basic weighted average common shares outstanding.
	Diluted earnings per share is calculated by taking net earnings, less earnings available to participating securities, divided by the diluted weighted average common shares outstanding.
	The elements used in the computation of basic and diluted earnings per share were as follows:

	The following is a reconciliation of the U.S. federal statutory tax rate of 35% to our effective income tax rates:

	(1)	In the fourth quarter of 2014, we recorded tax benefits of $188 related to the reinstatement of the research tax credit for 2014. Research tax credits for the 2013 and 2012 tax years were both recorded in 2013.
	(2)	In 2013, we recorded $212 for the issuance of favorable regulations related to research and experimental (R&E) expenditures.
	(3)	In the second quarter of 2014 we recorded an incremental tax benefit of $265 related to the application of a 2012 Federal Court of Claims decision which held that the tax basis in certain assets could be increased and realized upon the assets' disposition (tax basis adjustment).
	(4)	In the second quarter of 2014, tax benefits of $116 and $143 were recorded as a result of the 2007-2008 and 2009-2010 federal tax audit settlements.
	The research tax credit expired on December 31, 2014. If the research tax credit is not extended there would be an unfavorable impact to our 2015 effective income tax rate.
	Federal income tax audits have been settled for all years prior to 2011. The years 2011-2012 are currently being examined by the IRS. We are also subject to examination in major state and international jurisdictions for the 2001-2014 tax years. We believe appropriate provisions for all outstanding tax issues have been made for all jurisdictions and all open years.
	Significant components of our deferred tax (liabilities)/assets at December 31 were as follows:
		2014				2013
	Inventory and long-term contract methods of income recognition, fixed assets and other (net of valuation allowance of $18 and $20)		($11,589	)			($9,948	)

	(1)	Of the deferred tax asset for net operating loss and credit carryovers, $252 expires in years ending from December 31, 2015 through December 31, 2034 and $14 may be carried over indefinitely.
	(2)	Included in the net deferred tax (liabilities)/assets as of December 31, 2014 and 2013 are deferred tax assets in the amounts of $8,007 and $5,818 related to Accumulated other comprehensive loss.
	Net deferred tax (liabilities)/assets at December 31 were as follows:
		2014				2013
	Deferred tax assets		$14,219				$12,486
	Deferred tax liabilities	(16,028		)		(15,664		)
	Valuation allowance	(81		)		(125		)
	Net deferred tax (liabilities)/assets		($1,890	)			($3,303	)
	The measurement of deferred tax assets is reduced by a valuation allowance if, based upon available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
	We have provided for U.S. deferred income taxes and foreign withholding tax in the amount of $37 on undistributed earnings not considered indefinitely reinvested in our non-U.S. subsidiaries. We have not provided for U.S. deferred income taxes or foreign withholding tax on the remainder of undistributed earnings from our non-U.S. subsidiaries of approximately $800 because such earnings are considered to be indefinitely reinvested and it is not practicable to estimate the amount of tax that may be payable upon distribution.
	As of December 31, 2014 and 2013, the amounts accrued for the payment of income tax-related interest and penalties included in the Consolidated Statements of Financial Position were as follows: interest of $17 and $12 and penalties of $5 and $8. The amounts of interest benefit included in the Consolidated Statements of Operations were $17, $4, and $43 for the years ended December 31, 2014, 2013 and 2012, respectively. The interest benefit recorded during 2012 was primarily related to the settlement of non-US audits.
	A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
		2014				2013				2012
Unrecognized tax benefits – January 1		$1,141				$1,055				$939
Gross increases – tax positions in prior periods	403				10				55

Gross decreases – current-period tax positions					(1		)		(1		)
Settlements	(197		)						(1		)
Lapse of statute of limitations	(1		)
Unrecognized tax benefits – December 31		$1,312				$1,141				$1,055
As of December 31, 2014, 2013 and 2012, the total amount of unrecognized tax benefits was $1,312, $1,141 and $1,055, respectively, of which $1,180, $1,018 and $945 would affect the effective tax rate, if recognized. As of December 31, 2014, these amounts are primarily associated with U.S. federal tax issues such as the amount of research tax credits claimed, the domestic production activities deductions claimed, tax basis adjustments and U.S. taxation of foreign earnings. Also included in these amounts are accruals for domestic state tax issues such as the allocation of income among various state tax jurisdictions and the amount of state tax credits claimed.

	Accounts receivable at December 31 consisted of the following:
		2014			2013
	U.S. government contracts		$4,281			$3,604
	Defense, Space & Security customers (1)	1,018			1,073

	Total		$7,729			$6,546
	(1)	Excludes U.S. government contracts
	The following table summarizes our accounts receivable under long-term contracts that were unbillable or related to outstanding claims as of December 31:
		Unbillable						Claims
		2014			2013			2014		2013
	Current		$2,306			$1,550			$29		$3
	Expected to be collected after one year	1,408			1,020			73		61
	Total		$3,714			$2,570			$102		$64
	Under contract accounting unbillable receivables on long-term contracts arise when the sales or revenues based on performance attainment, though appropriately recognized, cannot be billed yet under terms of the contract as of the balance sheet date. Any adjustment for the credit quality of unbillable receivables, if required, would be recorded as a direct reduction of revenue. Factors considered in assessing the collectability of unbillable receivables include, but are not limited to, a customer’s extended delinquency, requests for restructuring and filings for bankruptcy. Unbillable receivables related to commercial customers expected to be collected after one year were $172 and $179 at December 31, 2014 and 2013. Accounts receivable related to claims are items that we believe are earned, but are subject to uncertainty concerning their determination or ultimate realization.
	Accounts receivable as of December 31, 2014, includes $112 of unbillable receivables on a long-term contract with LightSquared, LP (LightSquared) related to the construction of two commercial satellites. One of the satellites has been delivered, and the other is substantially complete but remains in Boeing’s possession. On May 14, 2012, LightSquared filed for Chapter 11 bankruptcy protection. We believe that our rights in the second satellite and related ground-segment assets are sufficient to protect the value of our receivables in the event LightSquared fails to make payments as contractually required or rejects its contract with us. Given the uncertainties inherent in bankruptcy proceedings, it is reasonably possible that we could incur losses related to these receivables in connection with the LightSquared bankruptcy.
	Accounts receivable, other than those described above, expected to be collected after one year are not material.

Customer Financing [Abstract]
Customer Financing	Customer Financing
	Customer financing primarily relates to the Boeing Capital (BCC) segment and consisted of the following at December 31:
		2014			2013
	Financing receivables:
	Investment in sales-type/finance leases		$1,535			$1,699
	Notes	370			587
	Total financing receivables	1,905			2,286
	Operating lease equipment, at cost, less accumulated depreciation of $571 and $564	1,677			1,734
	Gross customer financing	3,582			4,020
	Less allowance for losses on receivables	(21		)	(49		)
	Total		$3,561			$3,971
	The components of investment in sales-type/finance leases at December 31 were as follows:
		2014			2013
	Minimum lease payments receivable		$1,475			$1,731
	Estimated residual value of leased assets	521			543
	Unearned income	(461		)	(575		)
	Total		$1,535			$1,699
	Operating lease equipment primarily includes large commercial jet aircraft and regional jet aircraft. At December 31, 2014 and 2013, operating lease equipment included $48 and $83 of BCC equipment available for sale or re-lease. At December 31, 2014 and 2013, we had firm lease commitments for $0 and $57 of this equipment.
	Financing receivable balances evaluated for impairment at December 31 were as follows:
		2014			2013
	Individually evaluated for impairment		$86			$95
	Collectively evaluated for impairment	1,819			2,191
	Total financing receivables		$1,905			$2,286
	We determine a receivable is impaired when, based on current information and events, it is probable that we will be unable to collect amounts due according to the original contractual terms. At December 31, 2014 and 2013, we individually evaluated for impairment customer financing receivables of $86 and $95 and determined that none of these were impaired. As of December 31, 2014 and 2013, we had no material receivables that were greater than 30 days past due and we had no impaired customer financing receivables during 2014.
	Income recognition is generally suspended for financing receivables at the date full recovery of income and principal becomes not probable. Income is recognized when financing receivables become contractually current and performance is demonstrated by the customer. For the years ended December 31, 2013 and 2012, interest income recognized on such receivables was $30 and $6, and the average recorded investment in impaired financing receivables was $376 and $466.
	The change in the allowance for losses on financing receivables for the years ended December 31, 2014, 2013 and 2012, consisted of the following:
		2014			2013			2012
	Beginning balance - January 1		($49	)		($60	)		($70	)
	Customer financing valuation benefit	28			11			10
	Ending balance - December 31		($21	)		($49	)		($60	)
	Collectively evaluated for impairment		($21	)		($49	)		($60	)
	The adequacy of the allowance for losses is assessed quarterly. Three primary factors influencing the level of our allowance for losses on customer financing receivables are customer credit ratings, default rates and collateral values. We assign internal credit ratings for all customers and determine the creditworthiness of each customer based upon publicly available information and information obtained directly from our customers. Our rating categories are comparable to those used by the major credit rating agencies.
	Our financing receivable balances at December 31 by internal credit rating category are shown below:
	Rating categories	2014			2013
	BBB		$1,055			$1,091
	BB				58
	B	633			585
	CCC	131			457
	Other	86			95
	Total carrying value of financing receivables		$1,905			$2,286
	At December 31, 2014, our allowance related to receivables with ratings of B and BBB. We applied default rates that averaged 16% and 2% to the exposure associated with those receivables.
	Customer Financing Exposure
	Customer financing is collateralized by security in the related asset. The value of the collateral is closely tied to commercial airline performance and overall market conditions and may be subject to reduced valuation with market decline. Declines in collateral values are also a significant driver of our allowance for losses. Generally, out-of-production aircraft have experienced greater collateral value declines than in-production aircraft.
	Our customer financing portfolio is primarily collateralized by out-of-production 717, 757 and MD-80 aircraft. The majority of customer financing carrying values are concentrated in the following aircraft models at December 31:
		2014			2013
	717 Aircraft ($421 and $444 accounted for as operating leases)		$1,562			$1,674
	747 Aircraft ($601 and $183 accounted for as operating leases)	601			286
	757 Aircraft ($349 and $402 accounted for as operating leases)	370			453
	MD-80 Aircraft (Accounted for as sales-type finance leases)	358			411

Other Assets	Other Assets
	Sea Launch
	At December 31, 2014 and 2013, Other assets included $356 of receivables related to our former investment in the Sea Launch venture which became payable by certain Sea Launch partners following Sea Launch’s bankruptcy filing in June 2009. The $356 includes $147 related to a payment made by us under a bank guarantee on behalf of Sea Launch and $209 related to loans (partner loans) we made to Sea Launch. The net amounts owed to Boeing by each of the partners are as follows: S.P. Koroley Rocket and Space Corporation Energia of Russia – $223, PO Yuzhnoye Mashinostroitelny Zavod of Ukraine – $89 and KB Yuzhnoye of Ukraine – $44.
	Although each partner is contractually obligated to reimburse us for its share of the bank guarantee, the Russian and Ukrainian partners have raised defenses to enforcement and contested our claims. On October 19, 2009, we filed a Notice of Arbitration with the Stockholm Chamber of Commerce seeking reimbursement from the other Sea Launch partners of the $147 bank guarantee payment. On October 7, 2010, the arbitrator ruled that the Stockholm Chamber of Commerce lacked jurisdiction to hear the matter but did not resolve the merits of our claim. We filed a notice appealing the arbitrator’s ruling on January 11, 2011. On April 11, 2014, the appellate court entered a ruling that the decision of the arbitrator is not appealable. On May 9, 2014, we filed a brief with the Supreme Court of Sweden appealing the appellate court's April 11, 2014 ruling. On February 1, 2013, we filed an action in the United States District Court for the Central District of California seeking reimbursement from the other Sea Launch partners of the $147 bank guarantee payment and the $209 partner loan obligations. A trial in the United States District Court for the Central District of California is scheduled to commence July 14, 2015. We believe the partners have the financial wherewithal to pay and intend to pursue vigorously all of our rights and remedies. In the event we are unable to secure reimbursement of $147 related to our payment under the bank guarantee and $209 related to partner loans made to Sea Launch, we could incur additional charges. Our current assessment as to the collectability of these receivables takes into account the current economic conditions in Russia and Ukraine, although we will continue to monitor the situation.

	Environmental
	The following table summarizes environmental remediation activity during the years ended December 31, 2014 and 2013.
		2014			2013
	Beginning balance – January 1		$649			$710
	Reductions for payments made	(89		)	(120		)
	Changes in estimates	41			59
	Ending balance – December 31		$601			$649
	The liabilities recorded represent our best estimate or the low end of a range of reasonably possible costs expected to be incurred to remediate sites, including operation and maintenance over periods of up to 30 years. It is reasonably possible that we may incur charges that exceed these recorded amounts because of regulatory agency orders and directives, changes in laws and/or regulations, higher than expected costs and/or the discovery of new or additional contamination. As part of our estimating process, we develop a range of reasonably possible alternate scenarios that includes the high end of a range of reasonably possible cost estimates for all remediation sites for which we have sufficient information based on our experience and existing laws and regulations. There are some potential remediation obligations where the costs of remediation cannot be reasonably estimated. At December 31, 2014 and 2013, the high end of the estimated range of reasonably possible remediation costs exceeded our recorded liabilities by $874 and $928.

	Commercial Aircraft Commitments
	In conjunction with signing definitive agreements for the sale of new aircraft (Sale Aircraft), we have entered into trade-in commitments with certain customers that give them the right to trade in used aircraft at a specified price upon the purchase of Sale Aircraft. The probability that trade-in commitments will be exercised is determined by using both quantitative information from valuation sources and qualitative information from other sources. The probability of exercise is assessed quarterly, or as events trigger a change, and takes into consideration the current economic and airline industry environments. Trade-in commitments, which can be terminated by mutual consent with the customer, may be exercised only during the period specified in the agreement, and require advance notice by the customer.
	Trade-in commitment agreements at December 31, 2014 have expiration dates from 2015 through 2026. At December 31, 2014 and 2013, total contractual trade-in commitments were $2,392 and $1,605. As of December 31, 2014 and 2013, we estimated that it was probable we would be obligated to perform on certain of these commitments with net amounts payable to customers totaling $446 and $325 and the fair value of the related trade-in aircraft was $446 and $325.
	Financing Commitments
	Financing commitments related to aircraft on order, including options and those proposed in sales campaigns, totaled $16,723 and $17,987 as of December 31, 2014 and 2013. The estimated earliest potential funding dates for these commitments as of December 31, 2014 are as follows:
		Total
	2015		$2,552
	2016	3,710
	2017	3,497
	2018	2,305
	2019	1,738
	Thereafter	2,921
			$16,723
	As of December 31, 2014 all of these financing commitments related to customers we believe have less than investment-grade credit. We have concluded that no reserve for future potential losses is required for these financing commitments based upon the terms, such as collateralization and interest rates, under which funding would be provided.
	Standby Letters of Credit and Surety Bonds
	We have entered into standby letters of credit and surety bonds with financial institutions primarily relating to the guarantee of our future performance on certain contracts. Contingent liabilities on outstanding letters of credit agreements and surety bonds aggregated approximately $3,985 and $4,376 as of December 31, 2014 and 2013.
	Commitments to ULA
	We and Lockheed Martin Corporation have each committed to provide ULA with up to $527 of additional capital contributions in the event ULA does not have sufficient funds to make a required payment to us under an inventory supply agreement. See Note 6.
	C-17
	In September 2013, we decided to end production of C-17 aircraft in late 2015. In April 2014, we announced that we anticipate ending production approximately three months earlier based on our decision to produce three fewer aircraft in 2015 than previously planned. As a result, during the first quarter of 2014, BDS recorded $48 to write off inventory and accrue termination liabilities to suppliers. At December 31, 2014, our backlog included international orders for three C-17 aircraft that are scheduled for delivery in 2015 and we have active sales campaigns for the remaining seven unsold aircraft. We are currently incurring costs and have made commitments to suppliers related to these aircraft. We believe it is probable that we will recover costs related to the unsold aircraft from international customer orders. Should orders for the seven unsold aircraft not materialize or should we decide to discontinue production of unsold aircraft, we could incur further charges to write-down inventory and/or record termination liabilities. At December 31, 2014, we had approximately $1,091 of capitalized precontract costs and $385 of potential termination liabilities to suppliers associated with unsold aircraft.
	F/A-18
	At December 31, 2014, our backlog included 68 F/A-18 aircraft under contract with the U.S. Navy. The Consolidated and Further Continuing Appropriations Act, 2015, funds 15 additional F/A-18 aircraft. The orders in backlog, combined with anticipated orders for the 15 aircraft currently funded, would complete production in 2017. The President’s Fiscal Year 2016 budget request submitted in February 2015 did not include funding for additional F/A-18 aircraft. We are continuing to work with our U.S. customer as well as international customers to secure additional orders. Should additional orders not materialize, it is reasonably possible that we will decide in the next twelve months to end production of the F/A-18 at a future date. We are still evaluating the full financial impact of a potential production shutdown, including any recovery that may be available from the U.S. government.
	Company Owned Life Insurance
	McDonnell Douglas Corporation insured its executives with Company Owned Life Insurance (COLI), which are life insurance policies with a cash surrender value. Although we do not use COLI currently, these obligations from the merger with McDonnell Douglas are still a commitment at this time. We have loans in place to cover costs paid or incurred to carry the underlying life insurance policies. As of December 31, 2014 and 2013, the cash surrender value was $466 and $451 and the total loans were $439 and $425. As we have the right to offset the loans against the cash surrender value of the policies, we present the net asset in Other assets on the Consolidated Statements of Financial Position as of December 31, 2014 and 2013.
	United States Government Defense Environment Overview
	U.S. government appropriation levels remain subject to significant uncertainty. In August 2011, the Budget Control Act (The Act) established limits on U.S. government discretionary spending, including a reduction of defense spending by approximately $490 billion between the 2012 and 2021 U.S. government fiscal years. The Act also provided that the defense budget would face “sequestration” cuts of up to an additional $500 billion during that same period to the extent that discretionary spending limits are exceeded. While the impact of sequestration cuts was reduced with respect to FY2014 and FY2015 following the enactment of The Bipartisan Budget Act in December 2013, significant uncertainty remains with respect to overall levels of defense spending. It is likely that U.S. government discretionary spending levels for FY2016 and beyond will continue to be subject to significant pressure, including risk of future sequestration cuts.
	Significant uncertainty also continues with respect to program-level appropriations for the U.S. Department of Defense (U.S. DoD) and other government agencies, including the National Aeronautics and Space Administration, within the overall budgetary framework described above. Future budget cuts, including cuts mandated by sequestration, or future procurement decisions associated with the authorization and appropriations process could result in reductions, cancellations and/or delays of existing contracts or programs. Any of these impacts could have a material effect on the results of the Company’s operations, financial position and/or cash flows.
	In addition to the risks described above, if Congress is unable to pass appropriations bills in a timely manner, a government shutdown could result which could have impacts above and beyond those resulting from budget cuts or sequestration impacts. For example, requirements to furlough employees in the U.S. DoD or other government agencies could result in payment delays, impair our ability to perform work on existing contracts, and/or negatively impact future orders.
	BDS Fixed-Price Development Contracts
	Fixed-price development work is inherently uncertain and subject to significant variability in estimates of the cost and time required to complete the work. BDS fixed-price contracts with significant development work include Airborne Early Warning and Control, Commercial Crew, India P-8I, Saudi F-15, USAF KC-46A Tanker and commercial and military satellites. The operational and technical complexities of these contracts create financial risk, which could trigger termination provisions, order cancellations or other financially significant exposure. Changes to cost and revenue estimates could result in lower margins or material charges for reach-forward losses. For example, during the second quarter of 2014, higher estimated costs to complete the KC-46A Tanker contract for the U.S. Air Force resulted in a reach-forward loss of $425 of which the Commercial Airplanes segment recorded $238 and the BMA segment recorded $187.
	Recoverable Costs on Government Contracts
	Our final incurred costs for each year are subject to audit and review for allowability by the U.S. government, which can result in payment demands related to costs they believe should be disallowed. We work with the U.S. government to assess the merits of claims and where appropriate reserve for amounts disputed. If we are unable to satisfactorily resolve disputed costs, we could be required to record an earnings charge and/or provide refunds to the U.S. government.
	Russia/Ukraine
	We continue to monitor political unrest involving Russia and Ukraine, where we and some of our suppliers source titanium products and/or have operations. A number of our commercial customers also have operations in Russia and Ukraine. To date, we have not experienced any significant disruptions to production or deliveries. Should suppliers or customers experience disruption, our production and/or deliveries could be materially impacted.
	747 and 787 Commercial Airplane Programs
	The development and initial production of new commercial airplanes and new commercial airplane derivatives, which include the 747 and 787, entail significant commitments to customers and suppliers as well as substantial investments in working capital, infrastructure and research and development. The 747 and 787 programs had gross margins that were breakeven or near breakeven during 2014.
	Lower-than-expected demand for large commercial passenger and freighter aircraft have resulted in ongoing pricing pressures and fewer 747 orders than anticipated. We continue to have a number of unsold 747 production positions. If market, production and other risks cannot be mitigated, the program could face a reach-forward loss that may be material.
The combination of production challenges, change incorporation, schedule delays and customer and supplier impacts has created significant pressure on 787 program profitability. If risks related to this program, including risks associated with planned production rate increases or introducing and manufacturing the 787-10 derivative as scheduled cannot be mitigated, the program could face additional customer claims and/or supplier assertions, as well as a reach-forward loss that may be material.

Guarantees [Abstract]
Arrangements With Off-Balance Sheet Risk	Arrangements with Off-Balance Sheet Risk
	We enter into arrangements with off-balance sheet risk in the normal course of business, primarily in the form of guarantees.
	The following table provides quantitative data regarding our third party guarantees. The maximum potential payments represent a “worst-case scenario,” and do not necessarily reflect amounts that we expect to pay. Estimated proceeds from collateral and recourse represent the anticipated values of assets we could liquidate or receive from other parties to offset our payments under guarantees. The carrying amount of liabilities represents the amount included in Accrued liabilities.
		Maximum				Estimated				Carrying
		Potential				Proceeds from				Amount of
		Payments				Collateral/				Liabilities
						Recourse
	December 31,	2014		2013		2014		2013		2014		2013
	Contingent repurchase commitments		$1,375		$1,872		$1,364		$1,871		$5		$5
	Indemnifications to ULA:
	Contributed Delta program launch inventory	114		127
	Contract pricing	261		261						7		7
	Other Delta contracts	150		227								8
	Other indemnifications	63		106						20		28
	Credit guarantees	30		35		27		27		2		2
	Contingent Repurchase Commitments The repurchase price specified in contingent repurchase commitments is generally lower than the expected fair value at the specified repurchase date. Estimated proceeds from collateral/recourse in the table above represent the lower of the contracted repurchase price or the expected fair value of each aircraft at the specified repurchase date.
	Indemnifications to ULA In 2006, we agreed to indemnify ULA through December 31, 2020 against potential non-recoverability and non-allowability of $1,360 of Boeing Delta launch program inventory included in contributed assets plus $1,860 of inventory subject to an inventory supply agreement which ends on March 31, 2021. Since inception, ULA has consumed $1,246 of the $1,360 of inventory that was contributed by us and has yet to consume $114. ULA has made advance payments of $1,609 to us and we have recorded revenues and cost of sales of $1,287 under the inventory supply agreement through December 31, 2014.
	We agreed to indemnify ULA against potential losses that ULA may incur in the event ULA is unable to obtain certain additional contract pricing from the U.S. Air Force (USAF) for four satellite missions. We believe ULA is entitled to additional contract pricing. In December 2008, ULA submitted a claim to the USAF to re-price the contract value for two satellite missions. In March 2009, the USAF issued a denial of that claim. In June 2009, ULA filed a notice of appeal, and in October 2009, ULA filed a complaint before the Armed Services Board of Contract Appeals (ASBCA) for a contract adjustment for the price of the two satellite missions. In September 2009, the USAF exercised its option for a third satellite mission. During the third quarter of 2010, ULA submitted a claim to the USAF to re-price the contract value of the third mission. The USAF did not exercise an option for a fourth mission prior to the expiration of the contract. In March 2011, ULA filed a notice of appeal before the ASBCA, seeking to re-price the third mission. On November 20, 2013, the ASBCA denied USAF motions for summary judgment against ULA in large part, leaving ULA’s claims against the USAF substantially intact. The hearing before the ASBCA concluded on December 20, 2013. The parties filed their final post-hearing briefs in May 2014. The ASBCA may now issue a decision at any time. If ULA is ultimately unsuccessful in obtaining additional pricing, we may be responsible for an indemnification payment up to $261 and may record up to $278 in pre-tax losses associated with the three missions.
	Potential payments for Other Delta contracts include $85 related to deferred support costs. In June 2011, the Defense Contract Management Agency (DCMA) notified ULA that it had determined that $271 of deferred support costs are not recoverable under government contracts. In December 2011, the DCMA notified ULA of the potential non-recoverability of an additional $114 of deferred production costs. ULA and Boeing believe that all costs are recoverable and in November 2011, ULA filed a certified claim with the USAF for collection of deferred support and production costs. The USAF issued a final decision denying ULA’s certified claim in May 2012. On June 14, 2012, Boeing and ULA filed a suit in the Court of Federal Claims seeking recovery of the deferred support and production costs from the U.S. government. On November 9, 2012, the U.S. government filed an answer to our claim and asserted a counterclaim for credits that it alleges were offset by deferred support cost invoices. We believe that the U.S. government’s counterclaim is without merit, and have filed an answer challenging it on multiple grounds. The litigation is in the discovery phase and the Court has not yet set a trial date. If, contrary to our belief, it is determined that some or all of the deferred support or production costs are not recoverable, we could be required to record pre-tax losses and make indemnification payments to ULA for up to $317 of the costs questioned by the DCMA.
	Other Indemnifications As part of the 2004 sale agreement with General Electric Capital Corporation related to the sale of BCC’s Commercial Financial Services business, BCC is involved in a loss sharing arrangement for losses on transferred portfolio assets, such as asset sales, provisions for loss or asset impairment charges offset by gains from asset sales. At December 31, 2014 and 2013, our maximum future cash exposure to losses associated with the loss sharing arrangement was $63 and $106 and our accrued liability under the loss sharing arrangement was $20 and $28.
	In conjunction with our sales of Electron Dynamic Devices, Inc. and Rocketdyne Propulsion and Power businesses and our Commercial Airplanes facilities in Wichita, Kansas and Tulsa and McAlester, Oklahoma, we agreed to indemnify, for an indefinite period, the buyers for costs relating to pre-closing environmental conditions and certain other items. It is impossible to assess the potential number of future claims that may be asserted under these indemnifications, nor the amounts thereof (if any). As a result, we cannot estimate the maximum potential amount of future payments under these indemnities and therefore, no liability has been recorded. To the extent that claims have been made under these indemnities and/or are probable and reasonably estimable, liabilities associated with these indemnities are included in the environmental liability disclosure in Note 11.
	Credit Guarantees We have issued credit guarantees, principally to facilitate the sale and/or financing of commercial aircraft. Under these arrangements, we are obligated to make payments to a guaranteed party in the event that lease or loan payments are not made by the original lessee or debtor or certain specified services are not performed. A substantial portion of these guarantees has been extended on behalf of original lessees or debtors with less than investment-grade credit. Our commercial aircraft credit guarantees are collateralized by the underlying commercial aircraft and certain other assets. Current outstanding credit guarantees expire within the next six years.
	Industrial Revenue Bonds
	Industrial Revenue Bonds (IRB) issued by the City of Wichita were used to finance the purchase and/or construction of real and personal property at our Wichita site. Tax benefits associated with IRBs include a ten-year property tax abatement and a sales tax exemption from the Kansas Department of Revenue. We record the property on our Consolidated Statements of Financial Position, along with a capital lease obligation to repay the proceeds of the IRB. We have also purchased the IRBs and therefore are the bondholders as well as the borrower/lessee of the property purchased with the IRB proceeds.
	The capital lease obligation and IRB asset are recorded net in the Consolidated Statements of Financial Position. As of December 31, 2014 and 2013, the assets and liabilities associated with the City of Wichita IRBs were $638 and $690.

Debt Disclosure [Abstract]
Debt	Debt
	On October 31, 2014, we issued $300 of fixed rate senior notes due October 30, 2021 with an annual interest rate of 2.35%, $300 of fixed rate senior notes due October 30, 2024 with an annual interest rate of 2.85%, and $250 of floating rate senior notes due October 30, 2017. Each series of fixed rate senior notes may be redeemed at our option at any time for a redemption price equal to the full principal amount plus any accrued and unpaid interest and a make-whole premium. The floating rate senior notes bear interest at an annual rate equal to three-month LIBOR plus 12.5 basis points, and are not redeemable prior to maturity. The notes are unsecured senior obligations and rank equally in right of payment with our existing and future unsecured and unsubordinated indebtedness. The net proceeds of the issuance, after deducting underwriting discounts, commissions and offering expenses, totaled $838, of which $544 were used to fund BCC.
	Interest incurred, including amounts capitalized, was $504, $548 and $625 for the years ended December 31, 2014, 2013 and 2012, respectively. Interest expense recorded by BCC is reflected as Boeing Capital interest expense on our Consolidated Statements of Operations. Total Company interest payments were $511, $551 and $614 for the years ended December 31, 2014, 2013 and 2012, respectively.

Postretirement_Plans

Postretirement Plans	12 Months Ended
	Dec. 31, 2014
General Discussion of Pension and Other Postretirement Benefits [Abstract]
Postretirement Plans	Postretirement Plans
	The majority of our employees are earning benefits under defined benefit pension plans. In 2014, we announced changes to our retirement plans whereby nonunion and the majority of union employees currently participating in defined benefit pension plans will transition in 2016 to a company-funded defined contribution retirement savings plan.
	We fund our major pension plans through trusts. Pension assets are placed in trust solely for the benefit of the plans’ participants, and are structured to maintain liquidity that is sufficient to pay benefit obligations as well as to keep pace over the long-term with the growth of obligations for future benefit payments.
	We also have other postretirement benefits (OPB) other than pensions which consist principally of health care coverage for eligible retirees and qualifying dependents, and to a lesser extent, life insurance to certain groups of retirees. Retiree health care is provided principally until age 65 for approximately half those retirees who are eligible for health care coverage. Certain employee groups, including employees covered by most United Auto Workers bargaining agreements, are provided lifetime health care coverage.
	The funded status of the plans is measured as the difference between the plan assets at fair value and the projected benefit obligation (PBO). We have recognized the aggregate of all overfunded plans in Other assets, and the aggregate of all underfunded plans in either Accrued retiree health care or Accrued pension plan liability, net. The portion of the amount by which the actuarial present value of benefits included in the PBO exceeds the fair value of plan assets, payable in the next 12 months, is reflected in Accrued liabilities. The components of net periodic benefit cost were as follows:

	Total recognized in Accumulated other comprehensive loss		$21,706				$16,248				$365			($53	)
	The estimated amount that will be amortized from Accumulated other comprehensive loss into net periodic benefit cost during the year ended December 31, 2015 is as follows:
		Pension				Other Postretirement Benefits
	Recognized net actuarial loss		$1,581				$27
	Amortization of prior service costs/(credits)	193				(134		)
	Total		$1,774				($107	)
	The ABO for all pension plans was $75,655 and $63,491 at December 31, 2014 and 2013. Key information for our plans with ABO in excess of plan assets as of December 31 was as follows:
		2014				2013
	Projected benefit obligation		$78,358				$63,445
	Accumulated benefit obligation	75,622				58,334
	Fair value of plan assets	61,082				52,905
	Assumptions
	The following assumptions, which are the weighted average for all plans, are used to calculate the benefit obligation at December 31 of each year and the net periodic benefit cost for the subsequent year.
	December 31,	2014			2013			2012
Discount rate:
Pension	3.9	%		4.8	%		3.8	%
Other postretirement benefits	3.5	%		4.2	%		3.3	%
Expected return on plan assets	7	%		7.5	%		7.5	%
Rate of compensation increase	3.8	%		4	%		4	%
The discount rate for each plan is determined based on the plans’ expected future benefit payments using a yield curve developed from high quality bonds that are rated as Aa or better by at least half of the four rating agencies utilized as of the measurement date. The yield curve is fitted to yields developed from bonds at various maturity points. Bonds with the ten percent highest and the ten percent lowest yields are omitted. A portfolio of about 400 bonds is used to construct the yield curve. Since corporate bond yields are generally not available at maturities beyond 30 years, it is assumed that spot rates will remain level beyond that 30-year point. The present value of each plan’s benefits is calculated by applying the spot/discount rates to projected benefit cash flows. All bonds are U.S. issues, with a minimum outstanding of $50.
The pension fund’s expected return on plan assets assumption is derived from a review of actual historical returns achieved by the pension trust and anticipated future long-term performance of individual asset classes. While consideration is given to recent trust performance and historical returns, the assumption represents a long-term, prospective return. The expected return on plan assets component of the net periodic benefit cost for the upcoming plan year is determined based on the expected return on plan assets assumption and the market-related value of plan assets (MRVA). Since our adoption of the accounting standard for pensions in 1987, we have determined the MRVA based on a five-year moving average of plan assets. As of December 31, 2014, the MRVA was approximately $1,813 less than the fair market value of assets.
Assumed health care cost trend rates were as follows:
December 31,	2014			2013			2012
Health care cost trend rate assumed next year	7	%		7	%		7.5	%
Ultimate trend rate	5	%		5	%		5	%
Year that trend reached ultimate rate	2018			2018			2018
Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. To determine the health care cost trend rates we look at a combination of information including ongoing claims cost monitoring, annual statistical analyses of claims data, reconciliation of forecast claims against actual claims, review of trend assumptions of other plan sponsors and national health trends, and adjustments for plan design changes, workforce changes, and changes in plan participant behavior. A one-percentage-point change in assumed health care cost trend rates would have the following effect:
	Increase				Decrease
Effect on total of service and interest cost		$54				($45	)
Effect on postretirement benefit obligation	736				(613		)
During 2014 the Company conducted a mortality experience study and adopted new company specific tables for purposes of determining the Company’s mortality assumption used in the defined benefit plan liability calculation. The new tables resulted in an increase of $2,500 and $200 to the projected benefit obligation for pension and other postretirement benefits, respectively as of December 31, 2014.
Plan Assets
Investment Strategy The overall objective of our pension assets is to earn a rate of return over time to satisfy the benefit obligations of the pension plans and to maintain sufficient liquidity to pay benefits and address other cash requirements of the pension fund. Specific investment objectives for our long-term investment strategy include reducing the volatility of pension assets relative to pension liabilities, achieving a competitive, total investment return, achieving diversification between and within asset classes and managing other risks. Investment objectives for each asset class are determined based on specific risks and investment opportunities identified.
We periodically update our long-term, strategic asset allocations. We use various analytics to determine the optimal asset mix and consider plan liability characteristics, liquidity characteristics, funding requirements, expected rates of return and the distribution of returns. We identify investment benchmarks for the asset classes in the strategic asset allocation that are market-based and investable where possible.
Actual allocations to each asset class vary from target allocations due to periodic investment strategy changes, market value fluctuations, the length of time it takes to fully implement investment allocation positions (such as private equity and real estate), and the timing of benefit payments and contributions. Short-term investments and exchange-traded derivatives are used to rebalance the actual asset allocation to the target asset allocation. The asset allocation is monitored and rebalanced on a monthly basis.
The actual and target allocations by asset class for the pension assets at December 31 were as follows:
	Actual Allocations						Target Allocations
Asset Class	2014			2013			2014			2013
Fixed income	48	%		49	%		47	%		47	%
Global equity	29			29			26			26
Private equity	5			5			6			6
Real estate and real assets	9			8			11			11
Global strategies	4			4			4			4
Hedge funds	5			5			6			6
Total	100	%		100	%		100	%		100	%
Fixed income securities are invested broadly and primarily in long duration instruments. Global equity securities are invested broadly in U.S. and non-U.S. companies, across various industries and market capitalizations.
Real estate and real assets include global private investments that may be held through an investment in a limited partnership (LP) or other fund structures and publicly traded investments (such as Real Estate Investment Trusts (REIT) in the case of real estate). Real estate includes, but is not limited to, investments in office, retail, apartment and industrial properties. Real assets include, but are not limited to, investments in natural resources (such as energy, farmland and timber), commodities and infrastructure. Private equity investment vehicles are primarily limited partnerships (LPs) and fund-of-funds that mainly invest in U.S. and non-U.S. leveraged buyout, venture capital and special situation strategies.
Global strategies investments seek to capitalize on inefficiencies identified across different asset classes or markets, primarily using long-short positions in derivatives and physical securities. Hedge fund strategy types include, but are not limited to, event driven, relative value, long-short and multi-strategy.
Investment managers are retained for explicit investment roles specified by contractual investment guidelines. Certain investment managers are authorized to invest in derivatives, such as equity or bond futures, swaps, options and currency futures or forwards. Derivatives are used to achieve the desired market exposure of a security or an index, transfer value-added performance between asset classes, achieve the desired currency exposure, adjust portfolio duration or rebalance the total portfolio to the target asset allocation.
As a percentage of total pension plan assets, derivative net notional amounts were 3.5% and 18.3% for fixed income, including to-be-announced mortgage-backed securities and treasury forwards, and 2.0% and (2.2)% for global equity and commodities at December 31, 2014 and 2013.
Risk Management In managing the plan assets, we review and manage risk associated with funded status risk, interest rate risk, market risk, counterparty risk, liquidity risk and operational risk. Liability matching and asset class diversification are central to our risk management approach and are integral to the overall investment strategy. Further, asset classes are constructed to achieve diversification by investment strategy, by investment manager, by industry or sector and by holding. Investment manager guidelines for publicly traded assets are specified and are monitored regularly through the custodian. Credit parameters for counterparties have been established for managers permitted to trade over-the-counter derivatives. Valuation is governed through several types of procedures, including reviews of manager valuation policies, custodian valuation processes, pricing vendor practices, pricing reconciliation, and periodic, security-specific valuation testing.
Fair Value Measurements The following table presents our plan assets using the fair value hierarchy as of December 31, 2014 and 2013. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs, and Level 3 includes fair values estimated using significant unobservable inputs.

Fixed income securities are primarily valued upon a market approach, using matrix pricing and considering a security’s relationship to other securities for which quoted prices in an active market may be available, or an income approach, converting future cash flows to a single present value amount. Inputs used in developing fair value estimates include reported trades, broker quotes, benchmark yields, and base spreads.
Common/collective/pooled funds are typically common or collective trusts valued at their net asset values (NAVs) that are calculated by the investment manager or sponsor of the fund and have daily or monthly liquidity. Derivatives included in the table above are over-the-counter and are primarily valued using an income approach with inputs that include benchmark yields, swap curves, cash flow analysis, rating agency data and interdealer broker rates. Exchange-traded derivative positions are reported in accordance with changes in daily variation margin which is settled daily and therefore reflected in the payables and receivables portion of the table.
Cash equivalents and other short-term investments (which are used to pay benefits) are held in a separate account which consists of a commingled fund (with daily liquidity) and separately held short-term securities and cash equivalents. All of the investments in this cash vehicle are valued daily using a market approach with inputs that include quoted market prices for similar instruments. In the event a market price is not available for instruments with an original maturity of one year or less, amortized cost is used as a proxy for fair value. Common and preferred stock equity securities are primarily valued using a market approach based on the quoted market prices of identical instruments.
Private equity and private debt NAV valuations are based on the valuation of the underlying investments, which include inputs such as cost, operating results, discounted future cash flows and market based comparable data. For those investments reported on a one-quarter lagged basis (primarily LPs) we use NAVs, adjusted for subsequent cash flows and significant events.
Real estate and real asset NAV valuations are based on valuation of the underlying investments, which include inputs such as cost, discounted future cash flows, independent appraisals and market based comparable data. For those investments reported on a one-quarter lagged basis (primarily LPs) NAVs are adjusted for subsequent cash flows and significant events. Publicly traded REITs and infrastructure stocks are valued using a market approach based on quoted market prices of identical instruments. Exchange-traded commodities futures positions are reported in accordance with changes in daily variation margin which is settled daily and therefore reflected in the payables and receivables portion of the table.
Global strategies investments are primarily limited liability company (LLC) or mutual fund structures. The NAVs are based on valuation of the underlying investments, which are primarily valued using a market approach. The funds generally have monthly liquidity.
Hedge funds consist of fund-of-fund LLC structures and direct hedge funds. The NAVs of the fund-of-funds are based on the NAVs of the underlying hedge funds as well as any cash and accruals held at the fund-of-fund level. For direct hedge funds the NAVs are primarily based on valuation of the underlying investments. This is primarily done by applying a market or income valuation methodology depending on the specific type of security or instrument held. Redemptions in hedge funds are based on specific terms and conditions of the individual funds.
Investments in private equity, private debt, real estate, real assets, global strategies, and hedge funds are primarily calculated and reported by the General Partner (GP), fund manager or third party administrator. Pension assets invested in these structures rely on the NAV of these investments as the practical expedient for the valuations.

OPB Plan Assets The majority of OPB plan assets are invested in a balanced index fund which is comprised of approximately 60% equities and 40% debt securities. The index fund is valued using a market approach based on the quoted market price of an identical instrument (Level 1). The expected rate of return on these assets does not have a material effect on the net periodic benefit cost.
Cash Flows
Contributions Required pension contributions under the Employee Retirement Income Security Act (ERISA), as well as rules governing funding of our non-U.S. pension plans, are expected to be minimal in 2015. We do not expect contributions to our pension and OPB plans to be significant in 2015.
Estimated Future Benefit Payments The table below reflects the total pension benefits expected to be paid from the plans or from our assets, including both our share of the benefit cost and the participants’ share of the cost, which is funded by participant contributions. OPB payments reflect our portion only.
Year(s)	2015				2016				2017			2018				2019				2020-2024
Pensions		$3,448				$3,657				$3,828			$3,960				$3,977				$21,515

Subsidies	(38		)		(38		)		(40		)	(41		)		(42		)		(211		)
Net other postretirement benefits		$427				$457				$478			$517				$536				$2,763
Termination Provisions
Certain of the pension plans provide that, in the event there is a change in control of the Company which is not approved by the Board of Directors and the plans are terminated within five years thereafter, the assets in the plan first will be used to provide the level of retirement benefits required by ERISA, and then any surplus will be used to fund a trust to continue present and future payments under the postretirement medical and life insurance benefits in our group insurance benefit programs.
We have an agreement with the U.S. government with respect to certain pension plans. Under the agreement, should we terminate any of the plans under conditions in which the plan’s assets exceed that plan’s obligations, the U.S. government will be entitled to a fair allocation of any of the plan’s assets based on plan contributions that were reimbursed under U.S. government contracts.
Defined Contribution Plans
We provide certain defined contribution plans to all eligible employees. The principal plans are the Company-sponsored 401(k) plans. The expense for these defined contribution plans was $764, $742 and $708 in 2014, 2013 and 2012, respectively.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation And Other Compensation Arrangements	Share-Based Compensation and Other Compensation Arrangements
	Share-Based Compensation
	Our 2003 Incentive Stock Plan, as amended and restated, permits awards of incentive and non-qualified stock options, stock appreciation rights, restricted stock or units, performance shares, performance restricted stock or units, performance units and other stock and cash-based awards to our employees, officers, directors, consultants, and independent contractors. The aggregate number of shares of our stock authorized for issuance under the plan is 87,000,000.
	Shares issued as a result of stock option exercises or conversion of stock unit awards will be funded out of treasury shares, except to the extent there are insufficient treasury shares, in which case new shares will be issued. We believe we currently have adequate treasury shares to satisfy these issuances during 2015.
	Share-based plans expense is primarily included in General and administrative expense since it is incentive compensation issued primarily to our executives. The share-based plans expense and related income tax benefit were as follows:
	Years ended December 31,	2014				2013				2012
	Stock options		$62				$93				$85
	Restricted stock units and other awards	133				113				108
	Share-based plans expense		$195				$206				$193
	Income tax benefit		$70				$76				$75
	Stock Options
	In February 2013 and 2012, we granted to our executives 6,591,968 and 6,114,922 options, respectively. The options have been granted with an exercise price equal to the fair market value of our stock on the date of grant and expire ten years after the date of grant. The stock options vest over a period of three years, with 34% vesting after the first year, 33% vesting after the second year and the remaining 33% vesting after the third year. If an executive terminates employment for any reason, the non-vested portion of the stock option will not vest and all rights to the non-vested portion will terminate. We discontinued granting options in 2014, replacing them with performance-based restricted stock units.
	Stock option activity for the year ended December 31, 2014 is as follows:
		Shares		Weighted Average Exercise Price Per Share				Weighted Average Remaining Contractual Life (Years)		Aggregate Intrinsic Value
	Number of shares under option:
	Outstanding at beginning of year	23,767,743			$73.97
	Granted	20,008		124.98
	Exercised	-4,584,615		74.82
	Forfeited	-697,891		75.7
	Expired	-600		50.57
	Outstanding at end of year	18,504,645			$73.75			5.93			$1,041
	Exercisable at end of year	13,215,966			$72.74			5.1			$757
	The total intrinsic value of options exercised during the years ended December 31, 2014, 2013 and 2012 was $250, $546 and $89, respectively. Cash received from options exercised during the years ended December 31, 2014, 2013 and 2012 was $343, $1,097 and $120 with a related tax benefit of $87, $190 and $29, respectively, derived from the compensation deductions resulting from these option exercises. At December 31, 2014, there was $34 of total unrecognized compensation cost related to our stock option plan which is expected to be recognized over a weighted average period of one year. The grant date fair value of stock options vested during the years ended December 31, 2014, 2013 and 2012 was $87, $89 and $83, respectively.
	The fair values of options were estimated using the Black-Scholes option-pricing model with the following assumptions:
	Grant Year	Grant Date		Expected Life		Expected Volatility			Expected Dividend Yield			Risk Free Interest Rate		Weighted-Average Grant Date Fair Value Per Share
	2013	2/25/13		6 years		29	%		2.6	%		1	%		$15.85
	2012	2/27/12		6 years		29.9	%		2.4	%		1.1	%		$16.89
	The expected volatility of the stock options is based on a combination of our historical stock volatility and the volatility levels implied on the grant date by actively traded option contracts on our common stock. We determined the expected term of the stock option grants to be six years, calculated using the “simplified” method in accordance with the SEC Staff Accounting Bulletin 110. We use the “simplified” method since we changed the vesting terms, tax treatment and the recipients of our stock options beginning in 2006 such that we believe our historical data prior to 2006 does not provide a reasonable basis upon which to estimate expected term and we do not have enough option exercise data from our grants issued subsequent to 2006 to support our own estimate as a result of vesting terms and changes in the stock price.
	Restricted Stock Units
	In February 2014, 2013 and 2012, we granted to our executives 695,651, 1,375,414 and 1,369,810 restricted stock units (RSUs) as part of our long-term incentive program with grant date fair values of $129.58, $75.97 and $75.40 per unit, respectively. The RSUs granted under this program will vest and settle in common stock (on a one-for-one basis) on the third anniversary of the grant date. If an executive terminates employment because of retirement, involuntary layoff, disability, or death, the employee (or beneficiary) will receive a proration of stock units based on active employment during the three-year service period. In all other cases, the RSUs will not vest and all rights to the stock units will terminate. In addition to RSUs awarded under our long-term incentive program, we grant RSUs to certain executives and employees to encourage retention or to reward various achievements. These RSUs are labeled other RSUs in the table below. The fair values of all RSUs are estimated using the average of the high and low stock prices on the date of grant.
	RSU activity for the year ended December 31, 2014 was as follows:
		Long-Term Incentive Program				Other
	Number of units:
	Outstanding at beginning of year	3,722,317				1,132,930
	Granted	729,603				288,600
	Dividends	72,387				25,833
	Forfeited	(177,986		)		(13,962		)
	Distributed	(1,313,782		)		(286,303		)
	Outstanding at end of year	3,032,539				1,147,098
	Unrecognized compensation cost		$94				$41
	Weighted average remaining contractual life (years)	1.7				2.3
	The number of vested but undistributed RSUs at December 31, 2014 was not significant.
	Performance-Based Restricted Stock Units
	Performance-Based Restricted Stock Units (PBRSUs) are stock units that pay out based on the Company’s total shareholder return as compared to a group of peer companies over a three-year period. The award payout can range from 0% to 200% of the initial PBRSU grant, but will not exceed 400% of the initial value (excluding dividend equivalent credits). The PBRSUs granted under this program will vest at the payout amount and settle in common stock (on a one-for-one basis) on the third anniversary of the grant date. If an executive terminates employment because of retirement, involuntary layoff, disability, or death, the employee (or beneficiary) remains eligible under the award and, if the award is earned, will receive a proration of stock units based on active employment during the three-year service period. In all other cases, the PBRSUs will not vest and all rights to the stock units will terminate.
	In February 2014, we granted to our executives 662,215 initial PBRSUs as part of our long-term incentive program with a grant date fair value of $136.12 per unit. Compensation expense for the award is recognized over the three-year performance period based upon the grant date fair value estimated using a Monte-Carlo simulation model. The model used the following assumptions: expected volatility of 24.2% based upon our historical stock volatility, a risk-free interest rate of 0.72%, and no expected dividend yield because the units earn dividend equivalents.
	PBRSU activity for the year ended December 31, 2014 was as follows:
			Long-Term Incentive Program
	Number of units:
	Outstanding at beginning of year
	Granted		662,215
	Dividends		10,497
	Forfeited		(49,610		)
	Distributed		0
	Outstanding at end of year		623,102
	Unrecognized compensation cost			$53
	Weighted average remaining contractual life (years)		2.1
	Other Compensation Arrangements
	Performance Awards
	Performance Awards are cash units that pay out based on the achievement of long-term financial goals at the end of a three-year period. Each unit has an initial value of $100 dollars. The amount payable at the end of the three-year performance period may be anywhere from $0 to $200 dollars per unit, depending on the Company’s performance against plan for a three-year period. The Compensation Committee has the discretion to pay these awards in cash, stock, or a combination of both after the three-year performance period. Compensation expense, based on the estimated performance payout, is recognized ratably over the performance period.
	During 2014, 2013 and 2012, we granted Performance Awards to our executives with the payout based on the achievement of financial goals for each three-year period following the grant date. The minimum payout amount is $0 and the maximum amount we could be required to pay out for the 2014, 2013 and 2012 Performance Awards is $343, $261 and $251, respectively. The 2012 grant is expected to be paid out in cash in March 2015.
	Deferred Compensation
	The Company has a deferred compensation plan which permits executives to defer receipt of a portion of their salary, bonus, and certain other incentive awards. Participants can diversify deferred compensation among 23 investment funds including a Boeing stock unit account.
	Total expense related to deferred compensation was $44, $238 and $75 in 2014, 2013 and 2012, respectively. As of December 31, 2014 and 2013, the deferred compensation liability which is being marked to market was $1,234 and $1,258.

Summary of Derivative Instruments [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments
	Cash Flow Hedges
	Our cash flow hedges include foreign currency forward contracts, commodity swaps, and commodity purchase contracts. We use foreign currency forward contracts to manage currency risk associated with certain transactions, specifically forecasted sales and purchases made in foreign currencies. Our foreign currency contracts hedge forecasted transactions through 2019. We use commodity derivatives, such as swaps and fixed-price purchase commitments to hedge against potentially unfavorable price changes for items used in production. Our commodity contracts hedge forecasted transactions through 2017.
	Fair Value Hedges
	Interest rate swaps under which we agree to pay variable rates of interest are designated as fair value hedges of fixed-rate debt. The net change in fair value of the derivatives and the hedged items is reported in Boeing Capital interest expense.
	Derivative Instruments Not Receiving Hedge Accounting Treatment
	We also hold certain derivative instruments, primarily foreign currency forward contracts, for risk management purposes that are not receiving hedge accounting treatment.
	Notional Amounts and Fair Values
	The notional amounts and fair values of derivative instruments in the Consolidated Statements of Financial Position as of December 31 were as follows:
		Notional						Other assets						Accrued
		amounts(1)												liabilities
		2014			2013			2014			2013			2014			2013
	Derivatives designated as hedging instruments:

	Commodity contracts	3			9												(4		)
	Total derivatives		$3,064			$3,177		41			149			(233		)	(142		)
	Netting arrangements							(16		)	(63		)	16			63
	Net recorded balance								$25			$86			($217	)		($79	)
	(1)	Notional amounts represent the gross contract/notional amount of the derivatives outstanding.
	Gains/(losses) associated with our cash flow and undesignated hedging transactions and their effect on Other comprehensive income/(loss) and Net earnings were as follows:
	Years ended December 31,	2014			2013
	Effective portion recognized in Other comprehensive income/(loss), net of taxes:
	Foreign exchange contracts		($135	)		($76	)
	Commodity contracts	(2		)	1
	Effective portion reclassified out of Accumulated other comprehensive loss into earnings, net of taxes:
	Foreign exchange contracts	6			37
	Commodity contracts	(13		)	(20		)
	Forward points recognized in Other income, net:
	Foreign exchange contracts	28			34
	Undesignated derivatives recognized in Other income, net:
	Foreign exchange contracts	(7		)	17
	Based on our portfolio of cash flow hedges, we expect to reclassify losses of $98 (pre-tax) out of Accumulated other comprehensive loss into earnings during the next 12 months. Ineffectiveness related to our hedges recognized in Other income was insignificant for the years ended December 31, 2014 and 2013.
	We have derivative instruments with credit-risk-related contingent features. For foreign exchange contracts with original maturities of at least five years, our derivative counterparties could require settlement if we default on our five-year credit facility. For commodity contracts, our counterparties could require collateral posted in an amount determined by our credit ratings. The fair value of foreign exchange and commodity contracts that have credit-risk-related contingent features that are in a net liability position at December 31, 2014 was $20. At December 31, 2014, there was no collateral posted related to our derivatives.

Significant Group Concentrations Of Risk	Significant Group Concentrations of Risk
	Credit Risk
	Financial instruments involving potential credit risk are predominantly with commercial aircraft customers and the U.S. government. Of the $11,438 in gross accounts receivable and gross customer financing included in the Consolidated Statements of Financial Position as of December 31, 2014, $5,246 related predominantly to commercial aircraft customers ($1,664 of accounts receivable and $3,582 of customer financing) and $4,281 related to the U.S. government.
	Of the $3,582 in gross customer financing, $2,429 related to customers we believe have less than investment-grade credit including American Airlines, Hawaiian Airlines, and United/Continental Airlines who were associated with 11%, 9% and 8%, respectively, of our financing portfolio. Financing for aircraft is collateralized by security in the related asset and in some instances security in other assets as well.
	Other Risk
	As of December 31, 2014, approximately 39% of our total workforce was represented by collective bargaining agreements, the majority of which expire after 2015.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	The following table presents our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs and Level 3 includes fair values estimated using significant unobservable inputs.
		December 31, 2014										December 31, 2013
		Total			Level 1			Level 2			Level 3	Total			Level 1			Level 2			Level 3
	Assets
	Money market funds		$3,826			$3,826							$3,783			$3,783
	Available-for-sale investments	7			7							8			6							$2
	Derivatives	25							$25			86							$86
	Total assets		$3,858			$3,833			$25				$3,877			$3,789			$86			$2
	Liabilities
	Derivatives		($217	)					($217	)			($79	)					($79	)
	Total liabilities		($217	)					($217	)			($79	)					($79	)
	Money market funds and available-for-sale equity securities are valued using a market approach based on the quoted market prices of identical instruments. Available-for-sale debt investments are primarily valued using an income approach based on benchmark yields, reported trades and broker/dealer quotes.
	Derivatives include foreign currency, commodity and interest rate contracts. Our foreign currency forward contracts are valued using an income approach based on the present value of the forward rate less the contract rate multiplied by the notional amount. Commodity derivatives are valued using an income approach based on the present value of the commodity index prices less the contract rate multiplied by the notional amount. The fair value of our interest rate swaps is derived from a discounted cash flow analysis based on the terms of the contract and the interest rate curve.
	Certain assets have been measured at fair value on a nonrecurring basis using significant unobservable inputs (Level 3). The following table presents the nonrecurring losses recognized for the years ended December 31 due to long-lived asset impairment, and the fair value and asset classification of the related assets as of the impairment date:
		2014								2013
		Fair Value				Total Losses				Fair Value				Total Losses
	Operating lease equipment		$187				($170	)			$216				($81	)
	Property, plant and equipment	19				(15		)		40				(15		)
	Other assets and Acquired intangible assets					(17		)
	Total		$206				($202	)			$256				($96	)
	The fair value of the impaired operating lease equipment is derived by calculating a median collateral value from a consistent group of third party aircraft value publications. The values provided by the third party aircraft publications are derived from their knowledge of market trades and other market factors. Management reviews the publications quarterly to assess the continued appropriateness and consistency with market trends. Under certain circumstances, we adjust values based on the attributes and condition of the specific aircraft or equipment, usually when the features or use of the aircraft vary significantly from the more generic aircraft attributes covered by third party publications, or on the expected net sales price for the aircraft.
	Property, plant and equipment, Other assets and Acquired intangible assets were primarily valued using an income approach based on the discounted cash flows associated with the underlying assets.
	For Level 3 assets that were measured at fair value on a nonrecurring basis during the year ended December 31, 2014, the following table presents the fair value of those assets as of the measurement date, valuation techniques and related unobservable inputs of those assets.
		Fair		Valuation		Unobservable Input		Range
		Value		Technique(s)				Median or Average
	Operating lease equipment	$187		Market approach		Aircraft value publications		$158 - $268(1)
								Median $238
						Aircraft condition adjustments		($58) - $7(2)
								Net ($51)
	(1)	The range represents the sum of the highest and lowest values for all aircraft subject to fair value measurement, according to the third party aircraft valuation publications that we use in our valuation process.
	(2)	The negative amount represents the sum, for all aircraft subject to fair value measurement, of all downward adjustments based on consideration of individual aircraft attributes and condition. The positive amount represents the sum of all such upward adjustments.
	Fair Value Disclosures
	The fair values and related carrying values of financial instruments that are not required to be remeasured at fair value on the Consolidated Statements of Financial Position at December 31 were as follows:
		31-Dec-14
		Carrying Amount				Total Fair Value				Level 1		Level 2				Level 3
	Assets
	Accounts receivable, net		$7,729				$7,845						$7,845
	Notes receivable, net	366				395						395
	Liabilities
	Debt, excluding capital lease obligations	(8,909		)		(10,686		)				(10,480		)			($206	)
		December 31, 2013
		Carrying Amount				Total Fair Value				Level 1		Level 2				Level 3
	Assets
	Accounts receivable, net		$6,546				$6,525						$6,525
	Notes receivable, net	572				622						622
	Liabilities
	Debt, excluding capital lease obligations	(9,483		)		(10,897		)				(10,897		)
	The fair value of Accounts receivable is based on current market rates for loans of the same risk and maturities. The fair values of our variable rate notes receivable that reprice frequently approximate their carrying amounts. The fair values of fixed rate notes receivable are estimated with discounted cash flow analysis using interest rates currently offered on loans with similar terms to borrowers of similar credit quality. The fair value of our debt that is traded in the secondary market is classified as Level 2 and is based on current market yields. For our debt that is not traded in the secondary market, the fair value is classified as Level 2 and is based on our indicative borrowing cost derived from dealer quotes or discounted cash flows. The fair values of our debt classified as Level 3 are based on discounted cash flow models using the implied yield from similar securities. With regard to other financial instruments with off-balance sheet risk, it is not practicable to estimate the fair value of our indemnifications and financing commitments because the amount and timing of those arrangements are uncertain. Items not included in the above disclosures include cash, restricted cash, time deposits and other deposits, commercial paper, money market funds, Accounts payable and long-term payables. The carrying values of those items, as reflected in the Consolidated Statements of Financial Position, approximate their fair value at December 31, 2014 and 2013. The fair value of assets and liabilities whose carrying value approximates fair value is determined using Level 2 inputs, with the exception of cash (Level 1).

Loss Contingency, Information about Litigation Matters [Abstract]
Legal Proceedings	Legal Proceedings
	Various legal proceedings, claims and investigations related to products, contracts, employment and other matters are pending against us. Potentially material contingencies are discussed below.
	We are subject to various U.S. government investigations, from which civil, criminal or administrative proceedings could result or have resulted in the past. Such proceedings involve or could involve claims by the government for fines, penalties, compensatory and treble damages, restitution and/or forfeitures. Under government regulations, a company, or one or more of its operating divisions or subdivisions, can also be suspended or debarred from government contracts, or lose its export privileges, based on the results of investigations. We believe, based upon current information, that the outcome of any such government disputes and investigations will not have a material effect on our financial position, results of operations, or cash flows, except as set forth below. Where it is reasonably possible that we will incur losses in excess of recorded amounts in connection with any of the matters set forth below, we will disclose either the amount or range of reasonably possible losses in excess of such amounts or, where no such amount or range can be reasonably estimated, the reasons why no such estimate can be made.
	Employment, Labor and Benefits Litigation
	In connection with the 2005 sale of the former Wichita facility to Spirit AeroSystems, Inc. (Spirit), on February 16, 2007, an action entitled Harkness et al. v. The Boeing Company et al. was filed in the U.S. District Court for the District of Kansas, alleging collective bargaining agreement breaches and ERISA violations in connection with alleged failures to provide benefits to certain former employees of the Wichita facility. During the second quarter of 2014, the plaintiffs and Boeing agreed to settle the matter, subject to a fairness hearing, which has not been scheduled. The settlement would apply to approximately 2,000 employees who were subsequently employed by Spirit. Spirit is obligated to indemnify Boeing for settlement of this matter, and we intend to pursue full indemnification from Spirit. During the fourth quarter of 2014, Boeing filed a complaint against Spirit in Delaware Superior Court seeking to enforce our rights to indemnification and to recover from Spirit amounts incurred by Boeing for pension and retiree medical obligations. We cannot reasonably estimate the range of loss, if any, that may result from this matter pending the outcome of the fairness hearing.
	On October 13, 2006, we were named as a defendant in a lawsuit filed in the U.S. District Court for the Southern District of Illinois. Plaintiffs, seeking to represent a class of similarly situated participants and beneficiaries in The Boeing Company Voluntary Investment Plan (the VIP), alleged that fees and expenses incurred by the VIP were and are unreasonable and excessive, not incurred solely for the benefit of the VIP and its participants, and were undisclosed to participants. The plaintiffs further alleged that defendants breached their fiduciary duties in violation of §502(a)(2) of ERISA, and sought injunctive and equitable relief pursuant to §502(a)(3) of ERISA. Our motion for summary judgment was denied on December 30, 2014. We expect trial in this matter to begin during the second quarter of 2015. We cannot reasonably estimate the range of loss, if any, that may result from this matter given the current procedural status of the litigation.

Unallocated Pension and Other Postretirement Benefit Expense
Unallocated pension and other postretirement benefit expense represents the portion of pension and other postretirement benefit costs that are not recognized by business segments for segment reporting purposes. Through 2012, the business segments have been allocated pension and other postretirement benefit costs using U.S. Government Cost Accounting Standards (CAS), which employ different actuarial assumptions and accounting conventions than Generally Accepted Accounting Principles in the United States of America (GAAP). Beginning in 2013, pension costs, comprising GAAP service and prior service costs, are allocated to Commercial Airplanes. BDS continues to be allocated CAS pension costs which are allocable to government contracts. Other postretirement benefit costs will continue to be allocated to business segments based on CAS, which is generally based on benefits paid. Prior year allocations have not been adjusted.

Summary Of Significant Accounting Policies (Policy)	12 Months Ended

Accounting Policies [Abstract]
Description of New Accounting Pronouncements Not yet Adopted	Standards Issued and Not Yet Implemented
	In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers. The new standard is effective for reporting periods beginning after December 15, 2016 and early adoption is not permitted. The comprehensive new standard will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. Adoption of the new rules could affect the timing of revenue recognition for certain transactions. The guidance permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. For Boeing the new standard will be effective January 1, 2017 and the Company is currently evaluating the impacts of adoption and the implementation approach to be used.
Principles Of Consolidation And Basis Of Presentation	Principles of Consolidation and Basis of Presentation
	The Consolidated Financial Statements included in this report have been prepared by management of The Boeing Company (herein referred to as “Boeing,” the “Company,” “we,” “us,” or “our”). These statements include the accounts of all majority-owned subsidiaries and variable interest entities that are required to be consolidated. All significant intercompany accounts and transactions have been eliminated. Segment data for all years have been adjusted to reflect a realignment of certain programs from the Boeing Military Aircraft (BMA) segment to the Global Services & Support (GS&S) segment and the combination of Other segment with Unallocated items and eliminations. See Note 21.
Use Of Estimates	Use of Estimates
	Management makes assumptions and estimates to prepare financial statements in conformity with accounting principles generally accepted in the United States of America. Those assumptions and estimates directly affect the amounts reported in the Consolidated Financial Statements. Significant estimates for which changes in the near term are considered reasonably possible and that may have a material impact on the financial statements are disclosed in these Notes to the Consolidated Financial Statements.
Operating Cycle	Operating Cycle
	For classification of certain current assets and liabilities, we use the duration of the related contract or program as our operating cycle, which is generally longer than one year.
Revenue And Related Cost Recognition	Revenue and Related Cost Recognition
	Contract Accounting Contract accounting is used for development and production activities predominantly by Defense, Space & Security (BDS). The majority of business conducted by BDS is performed under contracts with the U.S. government and other customers that extend over several years. Contract accounting involves a judgmental process of estimating total sales and costs for each contract resulting in the development of estimated cost of sales percentages. For each contract, the amount reported as cost of sales is determined by applying the estimated cost of sales percentage to the amount of revenue recognized. When the current estimates of total sales and costs for a contract indicate a loss, a provision for the entire loss on the contract is recognized.
	Changes in estimated revenues, cost of sales and the related effect on operating income are recognized using a cumulative catch-up adjustment which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a contract’s percent complete. In 2014, 2013 and 2012 net favorable cumulative catch-up adjustments, including reach-forward losses, across all contracts increased Earnings from operations by $100, $242 and $379, respectively and diluted EPS by $0.10, $0.23 and $0.33, respectively. Significant adjustments during the three years ended December 31, 2014 included a reach-forward loss of $425 on the USAF KC-46A Tanker contract recorded during 2014.
	We combine contracts for accounting purposes when they are negotiated as a package with an overall profit margin objective. These essentially represent an agreement to do a single project for a single customer, involve interrelated construction activities with substantial common costs, and are performed concurrently or sequentially. When a group of contracts is combined, revenue and profit are earned uniformly over the performance of the combined contracts. Similarly, we may segment a single contract or group of contracts when a clear economic decision has been made during contract negotiations that would produce different rates of profitability for each element or phase of the contract.
	Sales related to fixed-price contracts are recognized as deliveries are made, except for certain fixed-price contracts that require substantial performance over an extended period before deliveries begin, for which sales are recorded based on the attainment of performance milestones. Sales related to contracts in which we are reimbursed for costs incurred plus an agreed upon profit are recorded as costs are incurred. The Federal Acquisition Regulations provide guidance on the types of cost that will be reimbursed in establishing contract price. Contracts may contain provisions to earn incentive and award fees if specified targets are achieved. Incentive and award fees that can be reasonably estimated and are probable are recorded over the performance period of the contract. Incentive and award fees that cannot be reasonably estimated are recorded when awarded.
	Program Accounting Our Commercial Airplanes segment predominantly uses program accounting to account for cost of sales related to its programs. Program accounting is applicable to products manufactured for delivery under production-type contracts where profitability is realized over multiple contracts and years. Under program accounting, inventoriable production costs, program tooling and other non-recurring costs, and warranty costs are accumulated and charged to cost of sales by program instead of by individual units or contracts. A program consists of the estimated number of units (accounting quantity) of a product to be produced in a continuing, long-term production effort for delivery under existing and anticipated contracts. The determination of the accounting quantity is limited by the ability to make reasonably dependable estimates of the revenue and cost of existing and anticipated contracts. To establish the relationship of sales to cost of sales, program accounting requires estimates of (a) the number of units to be produced and sold in a program, (b) the period over which the units can reasonably be expected to be produced, and (c) the units’ expected sales prices, production costs, program tooling and other non-recurring costs, and routine warranty costs for the total program.
	We recognize sales for commercial airplane deliveries as each unit is completed and accepted by the customer. Sales recognized represent the price negotiated with the customer, adjusted by an escalation formula as specified in the customer agreement. The amount reported as cost of sales is determined by applying the estimated cost of sales percentage for the total remaining program to the amount of sales recognized for airplanes delivered and accepted by the customer. Changes in estimated revenues, cost of sales and the related effects on program margins are recognized prospectively except in cases where the program is determined to have a reach-forward loss in which case the loss is recognized in the current period. See Note 11.
	Concession Sharing Arrangements We account for sales concessions to our customers in consideration of their purchase of products and services as a reduction to revenue when the related products and services are delivered. The sales concessions incurred may be partially reimbursed by certain suppliers in accordance with concession sharing arrangements. We record these reimbursements, which are presumed to represent reductions in the price of the vendor’s products or services, as a reduction in Cost of products.
	Spare Parts Revenue We recognize sales of spare parts upon delivery and the amount reported as cost of sales is recorded at average cost.
	Service Revenue Service revenue is recognized when the service is performed with the exception of U.S. government service agreements, which are accounted for using contract accounting. Service activities primarily include: support agreements associated with military aircraft and helicopter contracts, ongoing maintenance of International Space Station, and technical and flight operation services for commercial aircraft. Service revenue and associated cost of sales from pay-in-advance subscription fees are deferred and recognized as services are rendered.
	Financial Services Revenue We record financial services revenue associated with sales-type/finance leases, operating leases, and notes receivable.
	Lease and financing revenue arrangements are included in Sales of services on the Consolidated Statements of Operations. For sales-type/finance leases, we record an asset at lease inception. This asset is recorded at the aggregate future minimum lease payments, estimated residual value of the leased equipment, and deferred incremental direct costs less unearned income. Income is recognized over the life of the lease to approximate a level rate of return on the net investment. Residual values, which are reviewed periodically, represent the estimated amount we expect to receive at lease termination from the disposition of the leased equipment. Actual residual values realized could differ from these estimates. Declines in estimated residual value that are deemed other-than-temporary are recognized in the period in which the declines occur.
	For operating leases, revenue on leased aircraft and equipment is recorded on a straight-line basis over the term of the lease. Operating lease assets, included in Customer financing, are recorded at cost and depreciated over the period that we project we will hold the asset to an estimated residual value, using the straight-line method. We periodically review our estimates of residual value and recognize forecasted changes by prospectively adjusting depreciation expense.
	For notes receivable, notes are recorded net of any unamortized discounts and deferred incremental direct costs. Interest income and amortization of any discounts are recorded ratably over the related term of the note.
	Reinsurance Revenue Our wholly-owned insurance subsidiary, Astro Ltd., participates in a reinsurance pool for workers’ compensation. The member agreements and practices of the reinsurance pool minimize any participating members’ individual risk. Reinsurance revenues were $135, $160 and $129 during 2014, 2013 and 2012, respectively. Reinsurance costs related to premiums and claims paid to the reinsurance pool were $144, $147 and $128 during 2014, 2013 and 2012, respectively. Revenues and costs are presented net in Cost of sales in the Consolidated Statements of Operations.
Fleet Support	Fleet Support
	We provide assistance and services to facilitate efficient and safe aircraft operation to the operators of all our commercial airplane models. Collectively known as fleet support services, these activities and services include flight and maintenance training, field service support, engineering services, and technical data and documents. Fleet support activity begins prior to aircraft delivery as the customer receives training, manuals, and technical consulting support. This activity continues throughout the aircraft’s operational life. Services provided after delivery include field service support, consulting on maintenance, repair, and operational issues brought forth by the customer or regulators, updating manuals and engineering data, and the issuance of service bulletins that impact the entire model’s fleet. Field service support involves our personnel located at customer facilities providing and coordinating fleet support activities and requests. The costs for fleet support are expensed as incurred as Cost of services.
Research And Development	Research and Development
	Research and development includes costs incurred for experimentation, design, and testing, as well as bid and proposal efforts related to government products and services which are expensed as incurred unless the costs are related to certain contractual arrangements with customers. Costs that are incurred pursuant to such contractual arrangements are recorded over the period that revenue is recognized, consistent with our contract accounting policy. We have certain research and development arrangements that meet the requirement for best efforts research and development accounting. Accordingly, the amounts funded by the customer are recognized as an offset to our research and development expense rather than as contract revenues. Research and development expense included bid and proposal costs of $289, $285 and $326 in 2014, 2013 and 2012, respectively.
Share-Based Compensation	Share-Based Compensation
	We provide various forms of share-based compensation to our employees. For awards settled in shares, we measure compensation expense based on the grant-date fair value net of estimated forfeitures. For awards settled in cash, or that may be settled in cash, we measure compensation expense based on the fair value at each reporting date net of estimated forfeitures. The expense is recognized over the requisite service period, which is generally the vesting period of the award.
Income Taxes	Income Taxes
	Provisions for federal, state, and non-U.S. income taxes are calculated on reported Earnings before income taxes based on current tax law and also include, in the current period, the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provisions differ from the amounts currently receivable or payable because certain items of income and expense are recognized in different time periods for financial reporting purposes than for income tax purposes. Significant judgment is required in determining income tax provisions and evaluating tax positions.
	The accounting for uncertainty in income taxes requires a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. We record a liability for the difference between the benefit recognized and measured for financial statement purposes and the tax position taken or expected to be taken on our tax return. To the extent that our assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. Tax-related interest and penalties are classified as a component of Income tax expense.
Postretirement Plans	Postretirement Plans
	The majority of our employees are earning benefits under defined benefit pension plans. In 2014, we announced changes to our retirement plans whereby nonunion and the majority of union employees currently participating in defined benefit pension plans will transition in 2016 to a company-funded defined contribution retirement savings plan. We also provide postretirement benefit plans other than pensions, consisting principally of health care coverage to eligible retirees and qualifying dependents. Benefits under the pension and other postretirement benefit plans are generally based on age at retirement and years of service and, for some pension plans, benefits are also based on the employee’s annual earnings. The net periodic cost of our pension and other postretirement plans is determined using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate, the long-term rate of asset return, and medical trend (rate of growth for medical costs). A portion of net periodic pension and other postretirement income or expense is not recognized in net earnings in the year incurred because it is allocated to production as product costs, and reflected in inventory at the end of a reporting period. Actuarial gains and losses, which occur when actual experience differs from actuarial assumptions, are reflected in Shareholders’ equity (net of taxes). If actuarial gains and losses exceed ten percent of the greater of plan assets or plan liabilities we amortize them over the average future service period of employees. The funded status of our pension and postretirement plans is reflected on the Consolidated Statements of Financial Position.
Postemployment Plans	Postemployment Plans
	We record a liability for postemployment benefits, such as severance or job training, when payment is probable, the amount is reasonably estimable, and the obligation relates to rights that have vested or accumulated.
Environmental Remediation	Environmental Remediation
	We are subject to federal and state requirements for protection of the environment, including those for discharge of hazardous materials and remediation of contaminated sites. We routinely assess, based on in-depth studies, expert analyses and legal reviews, our contingencies, obligations, and commitments for remediation of contaminated sites, including assessments of ranges and probabilities of recoveries from other responsible parties and/or insurance carriers. Our policy is to accrue and charge to current expense identified exposures related to environmental remediation sites when it is probable that a liability has been incurred and the amount can be reasonably estimated. The amount of the liability is based on our best estimate or the low end of a range of reasonably possible exposure for investigation, cleanup, and monitoring costs to be incurred. Estimated remediation costs are not discounted to present value as the timing of payments cannot be reasonably estimated. We may be able to recover a portion of the remediation costs from insurers or other third parties. Such recoveries are recorded when realization of the claim for recovery is deemed probable.
	The liabilities recorded represent our best estimate or the low end of a range of reasonably possible costs expected to be incurred to remediate sites, including operation and maintenance over periods of up to 30 years. It is reasonably possible that we may incur charges that exceed these recorded amounts because of regulatory agency orders and directives, changes in laws and/or regulations, higher than expected costs and/or the discovery of new or additional contamination. As part of our estimating process, we develop a range of reasonably possible alternate scenarios that includes the high end of a range of reasonably possible cost estimates for all remediation sites for which we have sufficient information based on our experience and existing laws and regulations. There are some potential remediation obligations where the costs of remediation cannot be reasonably estimated.
Cash And Cash Equivalents	Cash and Cash Equivalents
	Cash and cash equivalents consist of highly liquid instruments, such as commercial paper, time deposits, and other money market instruments, which have original maturities of three months or less. We aggregate our cash balances by bank where conditions for right of set-off are met, and reclassify any negative balances, consisting mainly of uncleared checks, to Accounts payable. Negative balances reclassified to Accounts payable were $241 and $108 at December 31, 2014 and 2013.
Inventories	Inventories
	Inventoried costs on commercial aircraft programs and long-term contracts include direct engineering, production and tooling and other non-recurring costs, and applicable overhead, which includes fringe benefits, production related indirect and plant management salaries and plant services, not in excess of estimated net realizable value. To the extent a material amount of such costs are related to an abnormal event or are fixed costs not appropriately attributable to our programs or contracts, they are expensed in the current period rather than inventoried. Inventoried costs include amounts relating to programs and contracts with long-term production cycles, a portion of which is not expected to be realized within one year. Included in inventory for federal government contracts is an allocation of allowable costs related to manufacturing process reengineering.
	Commercial aircraft programs inventory includes deferred production costs and supplier advances. Deferred production costs represent actual costs incurred for production of early units that exceed the estimated average cost of all units in the program accounting quantity. Higher production costs are experienced at the beginning of a new or derivative airplane program. Units produced early in a program require substantially more effort (labor and other resources) than units produced later in a program because of volume efficiencies and the effects of learning. We expect that these deferred costs will be fully recovered when all units included in the accounting quantity are delivered as the expected unit cost for later deliveries is below the estimated average cost of all units in the program. Supplier advances represent payments for parts we have contracted to receive from suppliers in the future. As parts are received, supplier advances are amortized to work in process.
	The determination of net realizable value of long-term contract costs is based upon quarterly reviews that estimate costs to be incurred to complete all contract requirements. When actual contract costs and the estimate to complete exceed total estimated contract revenues, a loss provision is recorded. The determination of net realizable value of commercial aircraft program costs is based upon quarterly program reviews that estimate revenue and cost to be incurred to complete the program accounting quantity. When estimated costs to complete exceed estimated program revenues to go, a program loss provision is recorded in the current period for the estimated loss on all undelivered units in the accounting quantity.
	Used aircraft purchased by the Commercial Airplanes segment and general stock materials are stated at cost not in excess of net realizable value. See ‘Aircraft Valuation’ within this Note for a discussion of our valuation of used aircraft. Spare parts inventory is stated at lower of average unit cost or market. We review our commercial spare parts and general stock materials quarterly to identify impaired inventory, including excess or obsolete inventory, based on historical sales trends, expected production usage, and the size and age of the aircraft fleet using the part. Impaired inventories are charged to Cost of products in the period the impairment occurs.
	Included in inventory for commercial aircraft programs are amounts paid or credited in cash, or other consideration to certain airline customers, that are referred to as early issue sales consideration. Early issue sales consideration is recognized as a reduction to revenue when the delivery of the aircraft under contract occurs. If an airline customer does not perform and take delivery of the contracted aircraft, we believe that we would have the ability to recover amounts paid. However, to the extent early issue sales consideration exceeds advances and is not considered to be otherwise recoverable, it would be written off in the current period.
	We net advances and progress billings on long-term contracts against inventory in the Consolidated Statements of Financial Position. Advances and progress billings in excess of related inventory are reported in Advances and billings in excess of related costs.
Precontract Costs	Precontract Costs
	We may, from time to time, incur costs in excess of the amounts required for existing contracts. If we determine the costs are probable of recovery from future orders, then we capitalize the precontract costs we incur, excluding start-up costs which are expensed as incurred. Capitalized precontract costs are included in Inventories, net of advances and progress billings, in the accompanying Consolidated Statements of Financial Position. Should future orders not materialize or we determine the costs are no longer probable of recovery, the capitalized costs would be written off.
Property, Plant And Equipment	Property, Plant and Equipment
	Property, plant and equipment are recorded at cost, including applicable construction-period interest, less accumulated depreciation and are depreciated principally over the following estimated useful lives: new buildings and land improvements, from 10 to 40 years; and new machinery and equipment, from 3 to 20 years. The principal methods of depreciation are as follows: buildings and land improvements, 150% declining balance; and machinery and equipment, sum-of-the-years’ digits. Capitalized internal use software is included in Other assets and amortized using the straight line method over 5 years. We periodically evaluate the appropriateness of remaining depreciable lives assigned to long-lived assets, including assets that may be subject to a management plan for disposition.
	Long-lived assets held for sale are stated at the lower of cost or fair value less cost to sell. Long-lived assets held for use are subject to an impairment assessment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.
Asset Retirement Obligations	Asset Retirement Obligations
	We record all known asset retirement obligations for which the liability’s fair value can be reasonably estimated, including certain asbestos removal, asset decommissioning and contractual lease restoration obligations. Recorded amounts are not material.
	We also have known conditional asset retirement obligations, such as certain asbestos remediation and asset decommissioning activities to be performed in the future, that are not reasonably estimable due to insufficient information about the timing and method of settlement of the obligation. Accordingly, these obligations have not been recorded in the Consolidated Financial Statements. A liability for these obligations will be recorded in the period when sufficient information regarding timing and method of settlement becomes available to make a reasonable estimate of the liability’s fair value. In addition, there may be conditional asset retirement obligations that we have not yet discovered (e.g. asbestos may exist in certain buildings but we have not become aware of it through the normal course of business), and therefore, these obligations also have not been included in the Consolidated Financial Statements.
Goodwill And Other Acquired Intangibles	Goodwill and Other Acquired Intangibles
	Goodwill and other acquired intangible assets with indefinite lives are not amortized, but are tested for impairment annually and when an event occurs or circumstances change such that it is more likely than not that an impairment may exist. Our annual testing date is April 1.
	We test goodwill for impairment by performing a qualitative assessment or using a two-step impairment process. If we choose to perform a qualitative assessment and determine it is more likely than not that the carrying value of the net assets is more than the fair value of the related operations, the two-step impairment process is then performed; otherwise, no further testing is required. For operations where the two-step impairment process is used, we first compare the carrying value of net assets to the fair value of the related operations. If the fair value is determined to be less than carrying value, a second step is performed to compute the amount of the impairment. In this process, a fair value for goodwill is estimated, based in part on the fair value of the operations, and is compared to its carrying value. The shortfall of the fair value below carrying value represents the amount of goodwill impairment.
	Indefinite-lived intangibles consist of brand and trade names acquired in business combinations. We test these intangibles for impairment by comparing their carrying value to current projections of discounted cash flows attributable to the brand and trade names. Any excess carrying value over the amount of discounted cash flows represents the amount of the impairment.
	Our finite-lived acquired intangible assets are amortized on a straight-line basis over their estimated useful lives as follows: developed technology, from 5 to 14 years; product know-how, from 5 to 30 years; customer base, from 3 to 19 years; distribution rights, from 5 to 27 years; and other, from 3 to 32 years. We evaluate the potential impairment of finite-lived acquired intangible assets whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.
Investments	Investments
	Time deposits are held-to-maturity investments that are carried at cost.
	The equity method of accounting is used to account for investments for which we have the ability to exercise significant influence, but not control, over an investee. Significant influence is generally deemed to exist if we have an ownership interest in the voting stock of an investee of between 20% and 50%.
	We classify investment income and loss on our Consolidated Statements of Operations based on whether the investment is operating or non-operating in nature. Operating investments align strategically and are integrated with our operations. Earnings from operating investments, including our share of income or loss from equity method investments, dividend income from certain cost method investments, and any impairments or gain/loss on the disposition of these investments, are recorded in Income from operating investments, net. Non-operating investments are those we hold for non-strategic purposes. Earnings from non-operating investments, including interest and dividends on marketable securities, and any impairments or gain/loss on the disposition of these investments are recorded in Other income/(expense), net.
Derivatives	Derivatives
	All derivative instruments are recognized in the financial statements and measured at fair value regardless of the purpose or intent of holding them. We use derivative instruments to principally manage a variety of market risks. For derivatives designated as hedges of the exposure to changes in fair value of the recognized asset or liability or a firm commitment (referred to as fair value hedges), the gain or loss is recognized in earnings in the period of change together with the offsetting loss or gain on the hedged item attributable to the risk being hedged. The effect of that accounting is to include in earnings the extent to which the hedge is not effective in achieving offsetting changes in fair value. For our cash flow hedges, the effective portion of the derivative’s gain or loss is initially reported in comprehensive income and is subsequently reclassified into earnings in the same period or periods during which the hedged forecasted transaction affects earnings. The ineffective portion of the gain or loss of a cash flow hedge is reported in earnings immediately. We also hold certain instruments for economic purposes that are not designated for hedge accounting treatment. For these derivative instruments, the changes in their fair value are also recorded in earnings immediately.
Aircraft Valuation	Aircraft Valuation
	Used aircraft under trade-in commitments and aircraft under repurchase commitments In conjunction with signing a definitive agreement for the sale of new aircraft (Sale Aircraft), we have entered into trade-in commitments with certain customers that give them the right to trade in used aircraft at a specified price upon the purchase of Sale Aircraft. Additionally, we have entered into contingent repurchase commitments with certain customers wherein we agree to repurchase the Sale Aircraft at a specified price, generally 10 to 15 years after delivery of the Sale Aircraft. Our repurchase of the Sale Aircraft is contingent upon a future, mutually acceptable agreement for the sale of additional new aircraft. If we execute an agreement for the sale of additional new aircraft, and if the customer exercises its right to sell the Sale Aircraft to us, a contingent repurchase commitment would become a trade-in commitment. Our historical experience is that contingent repurchase commitments infrequently become trade-in commitments.
	Exposure related to trade-in commitments may take the form of:
	-1	adjustments to revenue for the difference between the contractual trade-in price in the definitive agreement and our best estimate of the fair value of the trade-in aircraft as of the date of such agreement, which would be recognized upon delivery of the Sale Aircraft, and/or
	-2	charges to cost of products for adverse changes in the fair value of trade-in aircraft that occur subsequent to signing of a definitive agreement for Sale Aircraft but prior to the purchase of the used trade-in aircraft. Estimates based on current aircraft values would be included in Accrued liabilities.
	The fair value of trade-in aircraft is determined using aircraft-specific data such as model, age and condition, market conditions for specific aircraft and similar models, and multiple valuation sources. This process uses our assessment of the market for each trade-in aircraft, which in most instances begins years before the return of the aircraft. There are several possible markets in which we continually pursue opportunities to place used aircraft. These markets include, but are not limited to, the resale market, which could potentially include the cost of long-term storage; the leasing market, with the potential for refurbishment costs to meet the leasing customer’s requirements; or the scrap market. Trade-in aircraft valuation varies significantly depending on which market we determine is most likely for each aircraft. On a quarterly basis, we update our valuation analysis based on the actual activities associated with placing each aircraft into a market. This quarterly valuation process yields results that are typically lower than residual value estimates by independent sources and tends to more accurately reflect results upon the actual placement of the aircraft.
	Used aircraft acquired by the Commercial Airplanes segment are included in Inventories at the lower of cost or market as it is our intent to sell these assets. To mitigate costs and enhance marketability, aircraft may be placed on operating lease. While on operating lease, the assets are included in Customer financing.
	Customer financing Customer financing includes operating lease equipment, notes receivable, and sales-type/finance leases. Sales-type/finance leases are treated as receivables, and allowances for losses are established as necessary.
	We assess the fair value of the assets we own, including equipment under operating leases, assets held for sale or re-lease, and collateral underlying receivables, to determine if their fair values are less than the related assets’ carrying values. Differences between carrying values and fair values of sales-type/finance leases and notes and other receivables, as determined by collateral value, are considered in determining the allowance for losses on receivables.
	We use a median calculated from published collateral values from multiple third-party aircraft value publications based on the type and age of the aircraft to determine the fair value of aircraft. Under certain circumstances, we apply judgment based on the attributes of the specific aircraft or equipment, usually when the features or use of the aircraft vary significantly from the more generic aircraft attributes covered by outside publications.
	Impairment review for assets under operating leases and held for sale or re-lease We evaluate for impairment assets under operating lease or assets held for sale or re-lease when events or changes in circumstances indicate that the expected undiscounted cash flow from the asset may be less than the carrying value. We use various assumptions when determining the expected undiscounted cash flow, including our intentions for how long we will hold an asset subject to operating lease before it is sold, the expected future lease rates, lease terms, residual value of the asset, periods in which the asset may be held in preparation for a follow-on lease, maintenance costs, remarketing costs and the remaining economic life of the asset. We record assets held for sale at the lower of carrying value or fair value less costs to sell.
	When we determine that impairment is indicated for an asset, the amount of impairment expense recorded is the excess of the carrying value over the fair value of the asset.
	Allowance for losses on customer financing receivables We record the potential impairment of customer financing receivables in a valuation account, the balance of which is an accounting estimate of probable but unconfirmed losses. The allowance for losses on receivables relates to two components of receivables: (a) receivables that are evaluated individually for impairment and (b) all other receivables.
	We determine a receivable is impaired when, based on current information and events, it is probable that we will be unable to collect amounts due according to the original contractual terms of the receivable agreement, without regard to any subsequent restructurings. Factors considered in assessing collectability include, but are not limited to, a customer’s extended delinquency, requests for restructuring and filings for bankruptcy. We determine a specific impairment allowance based on the difference between the carrying value of the receivable and the estimated fair value of the related collateral we would expect to realize.
	We review the adequacy of the allowance attributable to the remaining receivables (after excluding receivables subject to a specific impairment allowance) by assessing both the collateral exposure and the applicable cumulative default rate. Collateral exposure for a particular receivable is the excess of the carrying value of the receivable over the fair value of the related collateral. A receivable with an estimated fair value in excess of the carrying value is considered to have no collateral exposure. The applicable cumulative default rate is determined using two components: customer credit ratings and weighted average remaining contract term. Internally assigned credit ratings, our credit quality indicator, are determined for each customer in the portfolio. Those ratings are updated based upon public information and information obtained directly from our customers.
	We have entered into agreements with certain customers that would entitle us to look beyond the specific collateral underlying the receivable for purposes of determining the collateral exposure as described above. Should the proceeds from the sale of the underlying collateral asset resulting from a default condition be insufficient to cover the carrying value of our receivable (creating a shortfall condition), these agreements would, for example, permit us to take the actions necessary to sell or retain certain other assets in which the customer has an equity interest and use the proceeds to cover the shortfall.
	Each quarter we review customer credit ratings, published historical credit default rates for different rating categories, and multiple third-party aircraft value publications as a basis to validate the reasonableness of the allowance for losses on receivables. There can be no assurance that actual results will not differ from estimates or that the consideration of these factors in the future will not result in an increase or decrease to the allowance for losses on receivables.
Warranties	Warranties
	In conjunction with certain product sales, we provide warranties that cover factors such as non-conformance to specifications and defects in material and design. The majority of our warranties are issued by our Commercial Airplanes segment. Generally, aircraft sales are accompanied by a three to four-year standard warranty for systems, accessories, equipment, parts, and software manufactured by us or manufactured to certain standards under our authorization. These warranties are included in the programs’ estimate at completion. On occasion we have made commitments beyond the standard warranty obligation to correct fleet-wide major issues of a particular model, resulting in additional accrued warranty expense. Warranties issued by our BDS segments principally relate to sales of military aircraft and weapons hardware and are included in the contract cost estimates. These sales are generally accompanied by a six to twelve-month warranty period and cover systems, accessories, equipment, parts, and software manufactured by us to certain contractual specifications. Estimated costs related to standard warranties are recorded in the period in which the related product sales occur. The warranty liability recorded at each balance sheet date reflects the estimated number of months of warranty coverage outstanding for products delivered times the average of historical monthly warranty payments, as well as additional amounts for certain major warranty issues that exceed a normal claims level. Estimated costs of these additional warranty issues are considered changes to the initial liability estimate.
	We provide guarantees to certain commercial airplane customers which include compensation provisions for failure to meet specified aircraft performance targets. We account for these performance guarantees as warranties. The estimated liability for these warranties is based on known and anticipated operational characteristics and forecasted customer operation of the aircraft relative to contractually specified performance targets, and anticipated settlements when contractual remedies are not specified. Estimated payments are recorded as a reduction of revenue at delivery of the related aircraft. We have agreements that require certain suppliers to compensate us for amounts paid to customers for failure of supplied equipment to meet specified performance targets. Claims against suppliers under these agreements are included in Inventories and recorded as a reduction in Cost of products at delivery of the related aircraft. These performance warranties and claims against suppliers are included in the programs’ estimate at completion.
Supplier Penalties	Supplier Penalties
	We record an accrual for supplier penalties when an event occurs that makes it probable that a supplier penalty will be incurred and the amount is reasonably estimable. Until an event occurs, we fully anticipate accepting all products procured under production-related contracts.
Guarantees	Guarantees
	We record a liability in Accrued liabilities for the fair value of guarantees that are issued or modified after December 31, 2002. For a residual value guarantee where we received a cash premium, the liability is equal to the cash premium received at the guarantee’s inception. For credit guarantees, the liability is equal to the present value of the expected loss. We determine the expected loss by multiplying the creditor’s default rate by the guarantee amount reduced by the expected recovery, if applicable, for each future period the credit guarantee will be outstanding. If at inception of a guarantee, we determine there is a probable related contingent loss, we will recognize a liability for the greater of (a) the fair value of the guarantee as described above or (b) the probable contingent loss amount.

Earnings Per Share [Abstract]
Earnings Per Share, Policy	Basic and diluted earnings per share are computed using the two-class method, which is an earnings allocation method that determines earnings per share for common shares and participating securities. The undistributed earnings are allocated between common shares and participating securities as if all earnings had been distributed during the period. Participating securities and common shares have equal rights to undistributed earnings.
	Basic earnings per share is calculated by taking net earnings, less earnings available to participating securities, divided by the basic weighted average common shares outstanding.
	Diluted earnings per share is calculated by taking net earnings, less earnings available to participating securities, divided by the diluted weighted average common shares outstanding.

Environmental Remediation	Environmental Remediation
	We are subject to federal and state requirements for protection of the environment, including those for discharge of hazardous materials and remediation of contaminated sites. We routinely assess, based on in-depth studies, expert analyses and legal reviews, our contingencies, obligations, and commitments for remediation of contaminated sites, including assessments of ranges and probabilities of recoveries from other responsible parties and/or insurance carriers. Our policy is to accrue and charge to current expense identified exposures related to environmental remediation sites when it is probable that a liability has been incurred and the amount can be reasonably estimated. The amount of the liability is based on our best estimate or the low end of a range of reasonably possible exposure for investigation, cleanup, and monitoring costs to be incurred. Estimated remediation costs are not discounted to present value as the timing of payments cannot be reasonably estimated. We may be able to recover a portion of the remediation costs from insurers or other third parties. Such recoveries are recorded when realization of the claim for recovery is deemed probable.
	The liabilities recorded represent our best estimate or the low end of a range of reasonably possible costs expected to be incurred to remediate sites, including operation and maintenance over periods of up to 30 years. It is reasonably possible that we may incur charges that exceed these recorded amounts because of regulatory agency orders and directives, changes in laws and/or regulations, higher than expected costs and/or the discovery of new or additional contamination. As part of our estimating process, we develop a range of reasonably possible alternate scenarios that includes the high end of a range of reasonably possible cost estimates for all remediation sites for which we have sufficient information based on our experience and existing laws and regulations. There are some potential remediation obligations where the costs of remediation cannot be reasonably estimated.

The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs and Level 3 includes fair values estimated using significant unobservable inputs.
		December 31, 2014										December 31, 2013
