Basis Of Presentation	'
	Basis of Presentation
	The condensed consolidated interim 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”). In the opinion of management, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation are reflected in the interim financial statements. The results of operations for the period ended March 31, 2014 are not necessarily indicative of the operating results for the full year. The interim financial statements should be read in conjunction with the audited Consolidated Financial Statements, including the notes thereto, included in our 2013 Annual Report on Form 10-K. Effective during the first quarter of 2014, certain programs previously reported in the Boeing Military Aircraft (BMA) segment were realigned to the Global Services & Support (GS&S) segment. See Note 17. Business segment data for 2013 have been adjusted to reflect the realignment.
	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 Condensed 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 Condensed Consolidated Financial Statements.
	Contract accounting is used for development and production activities predominantly by Defense, Space & Security (BDS). 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. 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. For the three months ended March 31, 2014 and 2013, net favorable cumulative catch-up adjustments, including reach-forward losses, across all BDS contracts increased Earnings from operations by $167 and $105 and diluted earnings per share by $0.15 and $0.11.

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:
	(In millions - except per share amounts)	Three months ended March 31
		2014			2013
	Net earnings		$965			$1,106
	Less: earnings available to participating securities	2			3

	Diluted
	Basic weighted average shares outstanding	745			763.3
	Dilutive potential common shares(1)	9.1			5.4
	Diluted weighted average shares outstanding	754.1			768.7
	Less: participating securities	1.6			2.1
	Diluted weighted average common shares outstanding	752.5			766.6
	Net earnings per share:
	Basic		$1.30			$1.45
	Diluted	1.28			1.44
	(1)	Diluted EPS includes any dilutive impact of stock options, restricted stock units, performance-based restricted stock units and performance awards.
	The following table includes the number of shares that may be dilutive potential common shares in the future. These shares were not included in the computation of diluted earnings per share because the effect was either antidilutive or the performance condition was not met.

Income Taxes	'
	Income Taxes
	Our effective income tax rates were 33.9% and 23.1% for the three months ended March 31, 2014 and 2013. The effective tax rate for the first quarter of 2014 is higher than the comparable prior year period primarily due to the U.S. research and development tax credit (research tax credit). The research tax credit was effective for 2013, but due to the expiration at the end of 2013, no tax benefit is recorded in 2014. Furthermore, in the first quarter of 2013, Congress retroactively reinstated the research tax credit for 2012, which reduced income tax expense by $145. If Congress extends the research tax credit there will be a favorable impact on our 2014 effective income tax rate.
	Federal income tax audits have been settled for all years prior to 2007, as of March 31, 2014. On April 8, 2014, the Joint Committee on Taxation completed its review of the 2007-2008 tax years and as a result, a tax benefit of approximately $115 will be recorded in the second quarter of 2014. The years 2009-2010 are currently being examined by the Internal Revenue Service (IRS). We are also subject to examination in major state and international jurisdictions for the 2001-2013 tax years. We believe appropriate provisions for all outstanding tax issues have been made for all jurisdictions and all open years.
	Audit outcomes and the timing of audit settlements are subject to significant uncertainty. It is reasonably possible that within the next 12 months we will resolve the matters presently under consideration for the 2009-2010 tax years with the IRS. Depending on the timing and outcome of the audit settlement, unrecognized tax benefits that affect the effective tax rate could increase earnings by up to $130 based on current estimates.

Receivables [Abstract]	'
Accounts Receivable	'
	Accounts Receivable
	Accounts receivable as of March 31, 2014, includes $112 of unbillable receivables on a long-term contract with LightSquared, LLC (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.

	Total		$3,536			$3,971
	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 March 31, 2014 and December 31, 2013, we individually evaluated for impairment customer financing receivables of $97 and $95 and determined that none of these were impaired. We recorded no allowance for losses on these receivables as the collateral values exceed the carrying values of the receivables.
	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 by internal credit rating category are shown below.
	Rating categories	March 31			December 31
		2014			2013
	BBB		$1,065			$1,091
	BB	50			58
	B	727			585
	CCC	198			457
	Other	97			95
	Total carrying value of financing receivables		$2,137			$2,286
	At March 31, 2014, our allowance related to receivables with ratings of B and BBB to which we applied default rates that averaged 18% 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 aircraft. The majority of customer financing carrying values are concentrated in the following aircraft models:
		March 31			December 31
		2014			2013
	717 Aircraft ($438 and $444 accounted for as operating leases) (1)		$1,647			$1,674

	Other Assets
	Sea Launch
	At March 31, 2014 and December 31, 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. We intend to appeal the appellate court’s ruling with the Supreme Court of Sweden. 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 January 26, 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 pre-tax charges of up to $356. Our current assessment as to the collectability of these receivables takes into account the recent political unrest involving Russia and Ukraine, although we will continue to monitor the situation.

	Commitments and Contingencies
	Environmental
	The following table summarizes environmental remediation activity during the three months ended March 31, 2014 and 2013.
		2014			2013
	Beginning balance – January 1		$649			$710
	Reductions for payments made	(19		)	(8		)
	Changes in estimates	16			5
	Ending balance – March 31		$646			$707
	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 which include 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 March 31, 2014 and December 31, 2013, the high end of the estimated range of reasonably possible remediation costs exceeded our recorded liabilities by $923 and $928.
	Product Warranties
	The following table summarizes product warranty activity recorded during the three months ended March 31, 2014 and 2013.
		2014			2013
	Beginning balance – January 1		$1,570			$1,572
	Additions for current year deliveries	138			63
	Reductions for payments made	(106		)	(129		)
	Changes in estimates	47			1
	Ending balance - March 31		$1,649			$1,507
	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 March 31, 2014 have expiration dates from 2014 through 2023. At March 31, 2014, and December 31, 2013 total contractual trade-in commitments were $1,862 and $1,605. As of March 31, 2014 and December 31, 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 $477 and $325 and the fair value of the related trade-in aircraft was $477 and $325.
	Financing Commitments
	Financing commitments related to aircraft on order, including options and those proposed in sales campaigns, totaled $17,599 and $17,987 as of March 31, 2014 and December 31, 2013. The estimated earliest potential funding dates for these commitments as of March 31, 2014 are as follows:
		Total
	April through December 2014		$1,655
	2015	3,314
	2016	3,526
	2017	3,235
	2018	1,643
	Thereafter	4,226
			$17,599
	As of March 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 $4,310 and $4,376 as of March 31, 2014 and December 31, 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 5.
	C-17
	In September 2013, we decided to end production of C-17 aircraft in 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 three months ended March 31, 2014, BDS recorded $48 to write off inventory and accrue termination liabilities to suppliers. At March 31, 2014, our backlog included 3 international orders for C-17 aircraft that are scheduled for delivery through mid-2014 and we have active sales campaigns for the remaining 11 unsold aircraft that we plan to produce. We are currently incurring costs and have made commitments to suppliers related to the unsold aircraft. We believe it is probable that we will recover costs related to the unsold aircraft from international customer orders. Should orders for the 11 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 March 31, 2014, we had approximately $705 of capitalized precontract costs and $725 of potential termination liabilities to suppliers associated with the unsold aircraft.
	F/A-18
	At March 31, 2014, our backlog included 57 F/A-18 aircraft currently under contract with the U.S. Navy. In addition, the Fiscal Year 2013 and 2014 budgets include funding for an additional 44 aircraft. The President’s Fiscal Year 2015 budget request submitted in March 2014 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. The orders in backlog, combined with anticipated orders for the 44 aircraft currently funded, would complete production in 2016. 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.
	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. The impact of sequestration cuts was reduced with respect to FY2014 and FY2015 following the enactment of The Bipartisan Budget Act in December 2013. However, significant uncertainty remains with respect to overall levels of defense spending and it is likely that U.S. government discretionary spending levels 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 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, India P-8I, Saudi Arabia 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 also result in lower margins or a material charge for reach-forward losses in 2014.
	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 are monitoring recent 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 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 the three months ended March 31, 2014.
	Continued weakness in the air cargo market and lower-than-expected demand for large commercial passenger aircraft have resulted in pricing pressures and fewer 747 orders than anticipated. We continue to have a number of unsold 747 production positions. If market and production 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 the 787-9 and 787-10 derivatives 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.

	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 Proceeds from				Carrying Amount of
		Potential Payments				Collateral/Recourse				Liabilities
		March 31		December 31		March 31		December 31		March 31		December 31
		2014		2013		2014		2013		2014		2013
	Contingent repurchase commitments		$1,830		$1,872		$1,813		$1,871		$5		$5
	Indemnifications to ULA:
	Contributed Delta program launch inventory	125		127
	Contract pricing	261		261						7		7
	Other Delta contracts	226		227						8		8
	Other indemnifications	96		106						27		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 $1,235 of the $1,360 of inventory that was contributed by us and has yet to consume $125. ULA has made advance payments of $1,440 to us and we have recorded revenues and cost of sales of $1,104 under the inventory supply agreement through March 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 the USAF motions in large part, leaving three of four ULA counts, and its overall claims, substantially intact. The trial before the ASBCA concluded on December 20, 2013. The parties will complete post-trial briefing by May 2014. The Board will likely issue a ruling thereafter, but there is no scheduled date or official deadline for its decision. If ULA is ultimately unsuccessful in obtaining additional pricing, we may be responsible for a portion of the shortfall and may record up to $278 in pre-tax losses associated with the three missions, representing up to $261 for the indemnification payment and up to $17 for our portion of additional contract losses incurred by ULA.
	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. The DCMA has not yet issued a final decision related to the recoverability of the $114. 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 March 31, 2014 and December 31, 2013, our maximum future cash exposure to losses associated with the loss sharing arrangement was $96 and $106 and our accrued liability under the loss sharing arrangement was $27 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 9.
	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 seven years.

	Net periodic benefit cost included in Earnings from operations		$1,035			$791			$71			$91
	In the first quarter of 2014, we announced changes to our nonunion and certain union retirement plans whereby approximately 100,000 employees will transition in 2016 to a company-funded defined contribution retirement savings plan in lieu of participation in defined benefit pension plans. The defined benefit pension plan changes resulted in charges of $334 in the first quarter of 2014, primarily for pension curtailment costs. In addition, we remeasured pension assets and benefit obligations for the affected pension plans. These remeasurements resulted in a net actuarial gain of $966 which is included in Other Comprehensive Income. The $966 reflects a gain of $1,988 resulting from benefit plan changes that was partially offset by net actuarial losses of $1,022 primarily driven by a reduction in the discount rate from approximately 4.8% at December 31, 2013 to approximately 4.5% as of the remeasurement dates.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivative Financial Instruments	'
	Derivative Financial Instruments
	Cash Flow Hedges
	Our cash flow hedges include foreign currency forward contracts, foreign currency option contracts, commodity swaps, and commodity purchase contracts. We use foreign currency forward and option 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 principally occurring within five years in the future, with certain contracts hedging transactions through 2023. 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 Condensed Consolidated Statements of Financial Position were as follows:
		Notional amounts (1)						Other assets						Accrued liabilities
		March 31			December 31			March 31			December 31			March 31			December 31
		2014			2013			2014			2013			2014			2013

	Interest rate contracts	313			313			13			13
	Commodity contracts	50			72			3			2			(33		)	(39		)
	Derivatives not receiving hedge accounting treatment:

	Commodity contracts	7			9									(3		)	(4		)
	Total derivatives		$2,980			$3,177		144			149			(143		)	(142		)
	Netting arrangements							(56		)	(63		)	56			63
	Net recorded balance								$88			$86			($87	)		($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:
		Three months ended March 31
		2014				2013
	Effective portion recognized in Other comprehensive income/(loss), net of taxes:
	Foreign exchange contracts		($12	)			($26	)
	Commodity contracts	1
	Effective portion reclassified out of Accumulated other comprehensive loss into earnings, net of taxes:
	Foreign exchange contracts	(2		)		3
	Commodity contracts	(3		)		(5		)
	Forward points recognized in Other income, net:
	Foreign exchange contracts	7				8
	Undesignated derivatives recognized in Other income, net:
	Foreign exchange contracts	(4		)		(2		)
	Based on our portfolio of cash flow hedges, we expect to reclassify losses of $11 (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 three months ended March 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 March 31, 2014 was $10. At March 31, 2014, there was no collateral posted related to our derivatives.

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.
		March 31, 2014														December 31, 2013
		Total				Level 1				Level 2			Level 3			Total			Level 1		Level 2			Level 3
	Assets
	Money market funds		$2,101				$2,101										$3,783			$3,783
	Available-for-sale investments	11				9								$2		8			6						$2
	Derivatives	88									$88					86						$86
	Total assets		$2,200				$2,110				$88			$2			$3,877			$3,789		$86			$2
	Liabilities
	Derivatives		($87	)							($87	)					($79	)				($79	)
	Total liabilities		($87	)							($87	)					($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 three months ended March 31 and the fair value and asset classification of the related assets as of the impairment date:
		2014								2013
		Fair				Total				Fair			Total
		Value				Losses				Value			Losses
	Operating lease equipment		$27				($6	)			$28			($21	)
	Property, plant and equipment	2				(10		)		6			(5		)
	Total		$29				($16	)			$34			($26	)
	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 was 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 three months ended March 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	$27		Market approach		Aircraft value publications		$17 - $42(1)
								Median $32
						Aircraft condition adjustments		($5) - $0(2)
								Net ($5)
	(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 Condensed Consolidated Statements of Financial Position were as follows:
		March 31, 2014
		Carrying			Total Fair			Level 1	Level 2			Level 3
		Amount			Value
	Assets
	Accounts receivable, net		$7,341			$7,418				$7,418
	Notes receivable, net	478			517				517
	Liabilities
	Debt, excluding capital lease obligations	(8,796		)	(10,402		)		(10,402		)

	Assets
	Accounts receivable, net		$6,546			$6,525				$6,525

	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 value of our debt classified as Level 3 is based on the median of the underlying collateral value as described above. 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 Condensed Consolidated Statements of Financial Position, approximate their fair value at March 31, 2014 and December 31, 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).

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 our former Wichita facility to Spirit AeroSystems, Inc. (Spirit), certain individuals not hired by Spirit alleged that Spirit’s hiring decisions following the sale were tainted by age discrimination, violated the Employee Retirement Income Security Act (ERISA), violated our collective bargaining agreements, and constituted retaliation. The case was brought in 2006 as a class action on behalf of individuals not hired by Spirit. In 2012, the Tenth Circuit Court of Appeals affirmed the district court's 2010 summary judgment in favor of Boeing and Spirit on all class action claims, but the parties were not precluded from making claims on an individual basis. Claims with respect to twenty-six additional individuals were dismissed during the first quarter of 2014. As of March 31, 2014, sixty-two individual claims related to this matter were pending. Spirit has agreed to indemnify Boeing for any and all losses. We do not expect to incur any losses given the current status of this matter.
	Also related to the 2005 sale of the former Wichita facility, 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. On December 11, 2012 the court denied plaintiffs’ motion for summary judgment and granted Boeing’s motion for summary judgment on plaintiffs’ claim that amendment of The Boeing Company Employee Retirement Plan violated the IAM collective bargaining agreement, as well as individual ERISA §510 claims for interference with benefits. The court denied Boeing’s motion for all other claims. The parties are conducting additional discovery in anticipation of further court proceedings, which have not yet been scheduled. We believe that Spirit is obligated to indemnify Boeing for any and all losses in this matter, although to date Spirit has acknowledged a limited indemnification obligation. We currently estimate that the putative class includes up to approximately 2,000 former Wichita employees. We cannot reasonably estimate the range of loss, if any, that may result from this matter given the current procedural status of the litigation.
	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. During the first quarter of 2010, the Seventh Circuit Court of Appeals granted a stay of trial proceedings in the district court pending resolution of an appeal made by Boeing in 2008 to the case’s class certification order. On January 21, 2011, the Seventh Circuit reversed the district court’s class certification order and decertified the class. The Seventh Circuit remanded the case to the district court for further proceedings. On September 19, 2013, the district court granted plaintiffs’ motion for class certification. On October 3, 2013, Boeing filed a petition for review of the class certification order with the Seventh Circuit Court of Appeals, which was denied by the Seventh Circuit on November 26, 2013. Summary judgment briefs were filed in the district court on January 6, 2014, and plaintiffs’ opposition briefs were filed on February 10, 2014. We cannot reasonably estimate the range of loss, if any, that may result from this matter given the current procedural status of the litigation.

	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 Condensed 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 Condensed Consolidated Financial Statements.
	Contract accounting is used for development and production activities predominantly by Defense, Space & Security (BDS). 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. 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.

Earnings Per Share [Abstract]	'
Earnings Per Share Accounting 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.

	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 which include 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.
