Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Note 1 – 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 June 30, 2024, 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 herein. We added a new financial statement line item to the Condensed Consolidated Statements of Cash Flows for cash invested in Supplier notes receivable and reclassified the corresponding amounts in the prior period financial statements to conform to the current period presentation. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Goodwill We performed our annual goodwill impairment test as of April 1, 2024, using a qualitative assessment. We determined the fair value of each of our reporting units substantially exceeded their respective carrying values. Long-term Contracts Substantially all contracts at our Defense, Space & Security (BDS) segment and certain contracts at our Global Services (BGS) segment are long-term contracts with the U.S. government and other customers that generally extend over several years. Changes in estimated revenues, cost of sales, and the related effect on operating income are recognized using a cumulative catch-up percentage-of-completion. The table below reflects the impact of net cumulative catch-up (In millions – except per share amounts) Six months ended Three months ended 2024 2023 2024 2023 Decrease to Revenue ($ 965 ) ($ 782 ) ($ 747 ) ($ 470 ) Increase to Loss from operations ($ 1,700 ) ($ 1,348 ) ($ 1,334 ) ($ 830 ) Increase to Diluted loss per share ($ 2.62 ) ($ 1.43 ) ($ 2.06 ) ($ 0.51 )	Note 1 – 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. As described in Note 22, we now operate in three reportable segments: Commercial Airplanes (BCA), Defense, Space & Security (BDS), and Global Services (BGS). As a result, prior period amounts have been reclassified to conform to current period presentation. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. 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 Commercial aircraft contracts Payments for commercial aircraft sales are received in accordance with the customer agreement, which generally includes a deposit upon order and additional payments in accordance with a payment schedule, with the balance being due immediately prior to or at aircraft delivery. Advances and progress billings (contract liabilities) are normal and customary for commercial aircraft contracts and not considered a significant financing component as they are intended to protect us from the other party failing to adequately complete some or all of its obligations under the contract. Long-term contracts For each long-term contract, we determine the transaction price based on the consideration expected to be received. We allocate the transaction price to each distinct performance obligation to deliver a good or service, or a collection of goods and/or services, based on the relative standalone selling prices. A long-term contract will typically represent a single distinct performance obligation due to the highly interdependent and interrelated nature of the underlying goods and/or services and the significant service of integration that we provide. While the scope and price on certain long-term contracts may be modified over their life, the transaction price is based on current rights and obligations under the contract and does not include potential modifications until they are agreed upon with the customer. When applicable, a cumulative adjustment or separate recognition for the additional scope and price may result. Long-term contracts can be negotiated with a fixed price or a price in which we are reimbursed for costs incurred plus an agreed upon profit. The Federal Acquisition Regulations provide guidance on the types of cost that will be reimbursed in establishing the price for contracts with the U.S. government. Certain long-term contracts include in the transaction price variable consideration, such as incentive and award fees, if specified targets are achieved. The amount included in the transaction price represents the expected value, based on a weighted probability, or the most likely amount. Long-term contract revenue is recognized over the contract term (over time) as the work progresses, either as products are produced or as services are rendered. We generally recognize revenue over time as we perform on long-term contracts because of continuous transfer of control to the customer. For U.S. government contracts, this continuous transfer of control to the customer is supported by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay us for costs incurred plus a reasonable profit and take control of any work in process. Similarly, for non-U.S. The accounting for long-term contracts involves a judgmental process of estimating total revenues, costs and profit for each performance obligation. Cost of sales is recognized as incurred. The amount reported as revenues is determined by adding a proportionate amount of the estimated profit to the amount reported as cost of sales. Recognizing revenue as costs are incurred provides an objective measure of progress on the long-term contract and thereby best depicts the extent of transfer of control to the customer. For long-term contracts for which revenue is recognized over time, changes in estimated revenues, cost of sales and the related effect on operating income are recognized using a cumulative catch-up percentage-of-completion. The table below reflects the impact of net cumulative catch-up 2023 2022 2021 Decrease to Revenue ($ 1,706 ) ($ 2,335 ) ($ 379 ) Increase to Loss from operations ($ 2,943 ) ($ 5,253 ) ($ 880 ) Increase to Diluted loss per share ($ 5.43 ) ($ 8.88 ) ($ 1.28 ) Significant adjustments during the three years ended December 31, 2023 included losses on VC-25B, KC-46A MQ-25, T-7A F-15 Due to the significance of judgment in the estimation process, changes in underlying assumptions/estimates, internal and supplier performance, inflationary trends, or other circumstances may adversely or positively affect financial performance in future periods. Payments under long-term contracts may be received before or after revenue is recognized. The U.S. government customer typically withholds payment of a small portion of the contract price until contract completion. Therefore, long-term contracts typically generate Unbilled receivables (contract assets) but may generate Advances and progress billings (contract liabilities). Long-term contract Unbilled receivables and Advances and progress billings are not considered a significant financing component because they are intended to protect either the customer or the Company in the event that some or all of the obligations under the contract are not completed. Commercial spare parts contracts Other service revenue contracts Concession sharing arrangements Unbilled receivables and advances and progress billings Financial services revenue the leased equipment, and any 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. For notes receivable, we record financing receivables 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. Income recognition is generally suspended for financing receivables that are uncollectible. We determine that a financing receivable is uncollectible 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. We determine a financing receivable is past due when cash has not been received upon the due date specified in the contract. We evaluate the collectability of financing receivables at commencement and on a recurring basis. If a financing receivable is determined to be uncollectible, the customer is categorized as non-accrual non-accrual non-accrual non-accrual non-accrual 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 Financing receivables and operating lease equipment, net, are recorded at cost and depreciated to an estimated residual value using the straight-line method over the period that we project we will hold the asset. We periodically review our estimates of residual value and recognize forecasted changes by prospectively adjusting depreciation expense. We record assets held for sale at the lower of carrying value or fair value less costs to sell. We evaluate for impairment assets under operating leases when events or changes in circumstances indicate that the expected undiscounted cash flow from the asset may be less than the carrying value. 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. Reinsurance revenue 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 long-term 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, net included bid and proposal costs of $188, $217 and $213 in 2023, 2022 and 2021, respectively. 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 U.S. federal, state and local, and non-U.S. The accounting for uncertainty in income taxes requires a more-likely than-not Tax-related We also assess the likelihood that we will be able to recover our deferred tax assets against future sources of taxable income and reduce the carrying amounts of deferred tax assets by recording a valuation allowance if, based on the available evidence, it is more likely than not that all or a portion of such assets will not be realized. Changes in our estimates and judgments regarding realization of deferred tax assets may result in an increase or decrease to our tax expense and/or other comprehensive income, which would be recorded in the period in which the change occurs. Postretirement Plans Many of our employees have earned benefits under defined benefit pension plans. The majority of employees that had participated in defined benefit pension plans have transitioned 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). 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 expected future lifetime of participants. 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 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 Inventories Inventoried costs on commercial aircraft programs and long-term contracts include direct engineering, production and tooling and other non-recurring 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 aircraft 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 our BCA segment and general stock materials are stated at cost not in excess of net realizable value. Spare parts inventory is stated at lower of average unit cost or net realizable value. 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. 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 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 4 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’ 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. Leases Operating lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. We use our estimated incremental borrowing rate in determining the present value of lease payments. Variable components of the lease payments such as fair market value adjustments, utilities and maintenance costs are expensed as incurred and not included in determining the present value. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term. We have real property lease agreements with lease and non-lease 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 quantitative test. 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 quantitative test is then performed; otherwise, no further testing is required. For operations where the quantitative test is used, we compare the carrying value of net assets to the estimated fair value of the related operations. If the fair value is determined to be less than carrying value, the shortfall up to the carrying value of the goodwill represents the amount of goodwill impairment. Indefinite-lived intangibles consist of a brand and trade name and in-process Our finite-lived acquired intangible assets are amortized on a straight-line basis over their estimated useful lives as follows: developed technology, from 4 to 14 years; product know-how, Investments Time deposits are held-to-maturity Available-for-sale Available-for-sale available-for-sale Available-for-sale 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%. The cumulative earnings approach is used for cash flow classification of distributions received from equity method investments. Other Equity investments are recorded at fair value, with gains and losses recorded through net earnings. Equity investments without readily determinable fair value are measured at cost, less impairments, plus or minus observable price changes. Equity investments without readily determinable fair value are assessed for impairment quarterly. We classify investment income and loss on our Consolidated Statements of Operations based on whether the investment is operating or non-operating Non-operating non-strategic non-operating 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 our cash flow hedges, the derivative’s gain or loss is initially reported in comprehensive income and is subsequently reclassified into earnings in the same period(s) during which the hedged forecasted transaction affects earnings. We have agreements to purchase and sell aluminum to address long-term strategic sourcing objectives and non-U.S. Allowances for Losses on Certain Financial Assets We establish allowances for credit losses on accounts receivable, unbilled receivables, financing receivables and certain other financial assets. The adequacy of these allowances is assessed quarterly through consideration of factors such as customer credit ratings, bankruptcy filings, published or estimated credit default rates, age of the receivable, expected loss rates and collateral exposures. Collateral exposure is the excess of the carrying value of a financial asset over the fair value of the related collateral. We determine the creditworthiness of our customers by assigning internal credit ratings based upon publicly available information and information obtained directly from the customers. Our rating categories are comparable to those used by major credit rating agencies. Financing receivables are collateralized by security in the related asset. 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 collateral. 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. 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. 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. Commercial Aircraft Trade-in In conjunction with signing a definitive agreement for the sale of new commercial aircraft (Sale Aircraft), we have entered into trade-in Exposure related to trade-in (1) adjustments to revenue for the difference between the contractual trade-in trade-in (2) charges to cost of products for adverse changes in the fair value of trade-in trade-in The fair value of trade-in trade-in Trade-in Warranties In conjunction with certain product sales, we provide warranties that cover factors such as non-conformance 4-year two-year We provide guarantees to certain commercial aircraft 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 estimates to complete the related programs. Supplier Penalties We may incur penalties to suppliers under certain circumstances such as a contract termination. We record an accrual for supplier penalties when an event occurs that makes it probable we will incur a supplier penalty and the amount is reasonably estimable. Guarantees At the inception of a guarantee, we record a liability in Accrued liabilities for the fair value of the guarantee. 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. We also recognize a liability for the expected contingent loss at inception and adjust it each quarter.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Spirit Acquisitions	Note 2 – Spirit Acquisition On June 30, 2024, we entered into an Agreement and Plan of Merger (the Merger Agreement) pursuant to which we have agreed to acquire Spirit AeroSystems Holdings, Inc. (Spirit) in an all-stock Each share of Spirit common stock will be exchanged for a number of shares of Boeing common stock equal to an exchange ratio between 0.18 and 0.25, calculated as $37.25 divided by the volume weighted average share price of Boeing shares over the 15-trading-day Boeing’s acquisition of Spirit will include substantially all Boeing-related commercial operations, as well as certain other operations. Spirit has also entered into a binding term sheet with Airbus SE (Airbus) setting forth the terms upon which Airbus will, assuming the parties enter into definitive agreements and receive all required regulatory approvals, acquire certain commercial work packages that Spirit performs for Airbus concurrently with the closing of the Boeing-Spirit merger. In addition, Spirit is proposing to sell certain of its operations, including those in Belfast, Northern Ireland (non-Airbus The transaction is expected to close mid-2025 The Merger Agreement contains certain termination rights, including that either Boeing or Spirit may terminate the Merger Agreement if, subject to certain limitations, the transaction has not been consummated by March 31, 2025 (subject to three automatic three-month extensions if on each such date all of the closing conditions except those relating to regulatory approvals have been satisfied or waived) (the Outside Date). Additionally, Spirit may terminate the Merger Agreement under specified circumstances to accept an unsolicited Superior Proposal (as defined in the Merger Agreement) from a third party, and we may terminate the Merger Agreement if, before Spirit stockholder approval has been obtained, the Spirit Board of Directors changes its recommendation that Spirit’s stockholders adopt the Merger Agreement. The Merger Agreement provides that Spirit will be required to pay Boeing a termination fee of $150 if the Merger Agreement is terminated under specified circumstances in which the Spirit Board of Directors changes its recommendation that Spirit’s stockholders adopt the Merger Agreement, Spirit terminates the Merger Agreement in order to accept a Superior Proposal as set forth in the Merger Agreement, or Spirit consummates a Qualifying Transaction (as defined in the Merger Agreement) following the termination of the Merger Agreement. The Merger Agreement also provides that we will be required to pay Spirit a termination fee of $300 if the Merger Agreement is terminated by Spirit or Boeing under certain specified circumstances as a result of the parties’ failure to obtain the required regulatory approvals by the Outside Date or in the event that any law or order related to the required regulatory approvals or any applicable antitrust law or foreign investment law prohibits the consummation of the Merger.

Earnings Per Share [Abstract]
Earnings Per Share	Note 3 – Earnings Per Share Basic and diluted earnings per share are computed using the two-class Basic earnings per share is calculated by taking net earnings attributable to Boeing Shareholders, 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 attributable to Boeing Shareholders, less earnings available to participating securities, divided by the diluted weighted average common shares outstanding. Diluted weighted average common shares outstanding is calculated using the treasury stock method.

Note 3 – Earnings Per Share Basic and diluted earnings per share are computed using the two-class 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 attributable to Boeing Shareholders, 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 attributable to Boeing Shareholders, less earnings available to participating securities, divided by the diluted weighted average common shares outstanding. Diluted weighted average common shares outstanding is calculated using the treasury stock method. The elements used in the computation of basic and diluted earnings per share were as follows: (In millions – except per share amounts) Years ended December 31, 2023 2022 2021 Net loss attributable to Boeing Shareholders ($ 2,222 ) ($ 4,935 ) ($ 4,202 ) Less: earnings available to participating securities Net loss available to common shareholders ($ 2,222 ) ($ 4,935 ) ($ 4,202 ) Basic Basic weighted average shares outstanding 606.1 595.2 588.0 Less: participating securities(1) 0.3 0.3 0.4 Basic weighted average common shares outstanding 605.8 594.9 587.6 Diluted Diluted weighted average shares outstanding 606.1 595.2 588.0 Less: participating securities(1) 0.3 0.3 0.4 Diluted weighted average common shares outstanding 605.8 594.9 587.6 Net loss per share: Basic ($ 3.67 ) ($ 8.30 ) ($ 7.15 ) Diluted (3.67 ) (8.30 ) (7.15 ) (1) Participating securities include certain instruments in our deferred compensation plan.

Income Tax Disclosure [Abstract]
Income Taxes	Note 4 – Income Taxes We computed our 2024 interim tax provision using an estimated annual effective tax rate of (11.1%), adjusted for discrete items. Our 2024 estimated annual effective tax rate is primarily driven by taxes on non-U.S. As of December 31, 2023, we had recorded valuation allowances of $4,550 primarily for certain domestic deferred tax assets, and certain domestic net operating losses, tax credit and interest carryforwards. To measure the valuation allowance, the Company estimated in what year each of its deferred tax assets and liabilities would reverse using systematic and logical methods to estimate the reversal patterns. Based on these methods, deferred tax liabilities are assumed to reverse and generate taxable income over the next 5 to 10 years while deferred tax assets related to pension and other postretirement benefit obligations are assumed to reverse and generate tax deductions over the next 15 to 20 years. The valuation allowance results from not having sufficient income from deferred tax liability reversals in the appropriate future periods to support the realization of deferred tax assets. The total amount of unrecognized tax benefits of $1,131 as of December 31, 2023, decreased by $625 in the second quarter due to the settlement of the 2018-2020 federal tax audit, as discussed above. Federal income tax audits have been settled for all years prior to 2021. The Internal Revenue Service is expected to begin the 2021-2023 federal tax audit in the second quarter of 2025. We are also subject to examination in major state and international jurisdictions for the 2010-2022 tax years. We believe appropriate provisions for all outstanding tax issues have been made for all jurisdictions and all open years.

(2) Of the deferred tax asset for state net operating loss, credit, interest and other carryovers, $575 expires on or before December 31, 2043 and $562 may be carried over indefinitely. Net deferred tax assets/(liabilities) at December 31 were as follows: 2023 2022 Deferred tax assets $ 14,743 $ 12,301 Deferred tax liabilities (10,363 ) (9,306 ) Valuation allowance (4,550 ) (3,162 ) Net deferred tax assets/(liabilities) ($ 170 ) ($ 167 ) The Company’s deferred income tax assets of $14,743 can be used in future years to offset taxable income and reduce income taxes payable. The Company’s deferred income tax liabilities of $10,363 will partially offset deferred income tax assets and result in higher taxable income in future years and increase income taxes payable. Tax law determines whether future reversals of temporary differences will result in taxable and deductible amounts that offset each other in future years. The particular years in which temporary differences result in taxable or deductible amounts generally are determined by the timing of the recovery of the related asset or settlement of the related liability. The deferred income tax assets and liabilities relate primarily to U.S. federal and state tax jurisdictions. From a U.S. federal tax perspective, the Company generated tax net operating losses in 2021 and interest carryovers in 2021, 2022, and 2023 that can be carried forward indefinitely and federal research and development credits that can be carried forward 20 years. Throughout 2021, 2022, and 2023, the Company was in a three-year cumulative pre-tax As of December 31, 2023 and 2022, the Company has recorded valuation allowances of $4,550 and $3,162 primarily for certain domestic deferred tax assets, and certain domestic net operating losses, tax credit and interest carryforwards. To measure the valuation allowance, the Company estimated in what year each of its deferred tax assets and liabilities would reverse using systematic and logical methods to estimate the reversal patterns. Based on these methods, deferred tax liabilities are assumed to reverse and generate taxable income over the next 5 to 10 years while deferred tax assets related to pension and other postretirement benefit obligations are assumed to reverse and generate tax deductions over the next 15 to 20 years. The valuation allowance results from not having sufficient income from deferred tax liability reversals in the appropriate future periods to support the realization of deferred tax assets. During 2023, the Company increased the valuation allowance by $1,388, primarily due to tax credits and other carryforwards generated in 2023 that cannot be realized in 2023. This reflects a tax expense of $1,150 recorded in continuing operations, an increase of $31 related to the associated federal benefit of state impacts, a tax expense of $173 included in Other comprehensive income (OCI) primarily due to the net actuarial losses that resulted from the annual remeasurement of pension assets and liabilities, and an increase of $34 included in additional paid-in Until the Company generates sustained levels of profitability, additional valuation allowances may have to be recorded with corresponding adverse impacts on earnings and/or OCI. The Tax Cuts and Jobs Act one-time non-U.S. As of December 31, 2023 and 2022, the amounts accrued for the payment of income tax-related A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: 2023 2022 2021 Unrecognized tax benefits – January 1 $ 915 $ 858 $ 966 Gross increases – tax positions in prior periods 38 17 64 Gross decreases – tax positions in prior periods (3 ) (51 ) (245 ) Gross increases – current period tax positions 181 91 73 Gross decreases – current period tax positions Unrecognized tax benefits – December 31 $ 1,131 $ 915 $ 858 As of December 31, 2023, 2022 and 2021, the total amount of unrecognized tax benefits include $1,088, $878 and $790, respectively, that would affect the effective tax rate, if recognized. As of December 31, 2023, these amounts were primarily associated with the amount of research tax credits claimed and various other matters. Federal income tax audits have been settled for all years prior to 2018. The Internal Revenue Service is currently auditing the 2018-2020 tax years. We are also subject to examination in major state and international jurisdictions for the 2010-2022 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, unrecognized tax benefits related to federal tax matters under audit may decrease by up to $620 based on current estimates.

Commitments and Contingencies Disclosure [Abstract]
Liabilities, Commitments and Contingencies	Note 10 – Liabilities, Commitments and Contingencies 737 MAX Customer Concessions and Other Considerations During the first quarter of 2024, we recorded an earnings charge of $443, net of insurance recoveries, in connection with estimated considerations to customers for disruption related to the Alaska Airlines 737-9 737-9 The following table summarizes changes in the 737 MAX customer concessions and other considerations liability during the six months ended June 30, 2024 and 2023. 2024 2023 Beginning balance – January 1 $ 1,327 $ 1,864 Reductions for payments made (681 ) (273 ) Reductions for concessions and other in-kind (221 ) (51 ) Changes in estimates 510 (26 ) Ending balance – June 30 $ 935 $ 1,514 At June 30, 2024, $92 of the liability balance remains subject to negotiations with customers. The contracted amount includes $208 expected to be paid in cash in 2024, while the remaining amounts are primarily expected to be liquidated by lower customer delivery payments. Environmental The following table summarizes changes in environmental remediation liabilities during the six months ended June 30, 2024 and 2023. 2024 2023 Beginning balance – January 1 $ 844 $ 752 Reductions for payments made, net of recoveries (40 ) (24 ) Changes in estimates 27 72 Ending balance – June 30 $ 831 $ 800 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 costs 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 June 30, 2024 and December 31, 2023, the high end of the estimated range of reasonably possible remediation costs exceeded our recorded liabilities by $964 and $1,030. Product Warranties The following table summarizes changes in product warranty liabilities recorded during the six months ended June 30, 2024 and 2023. 2024 2023 Beginning balance – January 1 $ 2,448 $ 2,275 Additions for current year deliveries 42 92 Reductions for payments made (227 ) (179 ) Changes in estimates (8 ) 338 Ending balance – June 30 $ 2,255 $ 2,526 Commercial Aircraft Trade-In In conjunction with signing definitive agreements for the sale of new aircraft, we have entered into trade-in trade-in Trade-in Trade-in trade-in trade-in Financing Commitments Financing commitments related to aircraft on order, including options and those proposed in sales campaigns, and refinancing of delivered aircraft, totaled $17,356 and $17,003 as of June 30, 2024 and December 31, 2023. The estimated earliest potential funding dates for these commitments as of June 30, 2024 are as follows: Total July through December 2024 $ 1,508 2025 3,529 2026 4,027 2027 2,891 2028 1,643 Thereafter 3,758 Total $ 17,356 As of June 30, 2024, $14,030 of these financing commitments relate 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. Other Financial Commitments We have financial commitments to make additional capital contributions totaling $262 to certain joint ventures over the next nine years. 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 and security agreements. Contingent liabilities on outstanding letters of credit agreements and surety bonds aggregated approximately Supply Chain Financing Programs The Company has supply chain financing programs in place under which participating suppliers may elect to obtain payment from an intermediary. The Company confirms the validity of invoices from participating suppliers and agrees to pay the intermediary an amount based on invoice totals. The majority of amounts payable under these programs are due within 30 to 90 days but may extend up to 12 months. At June 30, 2024 and December 31, 2023, Accounts payable included $2.7 billion and $2.9 billion payable to suppliers who have elected to participate in these programs. We do not believe that future changes in the availability of supply chain financing would have a significant impact on our liquidity. 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. Fixed-Price Contracts Long-term contracts that are contracted on a fixed-price basis could result in losses in future periods. Certain of the fixed-price contracts are for the development of new products, services and related technologies. This development work scope is inherently uncertain and subject to significant variability in estimates of the cost and time required to complete the work by us and our suppliers. The operational and technical complexities of fixed-price development contracts create financial risk, which could trigger additional earnings charges, termination provisions, order cancellations, or other financially significant exposure. VC-25B The Company’s firm fixed-price contract for the Engineering and Manufacturing Development (EMD) effort on the U.S. Air Force’s (USAF) VC-25B 747-8 KC-46A In 2011, we were awarded a contract from the USAF to design, develop, manufacture, and deliver four next generation aerial refueling tankers as well as priced options for 13 annual production lots totaling 179 aircraft. Since 2016, the USAF has authorized ten low rate initial production (LRIP) lots for a total of 139 aircraft. The EMD contract and authorized LRIP lots total approximately $27 billion as of June 30, 2024. The KC-46A During 2023, we increased the reach-forward loss on the KC-46A MQ-25 In the third quarter of 2018, we were awarded the MQ-25 T-7A In 2018, we were awarded the T-7A T-7A During 2023, we increased the reach-forward loss on the T-7A T-7A Commercial Crew National Aeronautics and Space Administration (NASA) has contracted us to design and build the CST-100	Note 13 – Liabilities, Commitments and Contingencies Accrued Liabilities Accrued liabilities at December 31 consisted of the following: 2023 2022 Accrued compensation and employee benefit costs $ 6,721 $ 6,351 737 MAX customer concessions and other considerations 1,327 1,864 Other customer concessions and considerations 1,300 1,102 Environmental 844 752 Product warranties 2,448 2,275 Forward loss recognition 4,699 4,060 Accrued interest payable 652 599 Current portion of lease liabilities 296 276 Current portion of retiree healthcare and pension liabilities 473 494 Other 3,571 3,808 Total $ 22,331 $ 21,581 737 MAX Customer Concessions and Other Considerations The following table summarizes changes in the 737 MAX customer concessions and other considerations liability during 2023 and 2022. 2023 2022 Beginning balance – January 1 $ 1,864 $ 2,940 Reductions for payments made (449 ) (1,031 ) Reductions for concessions and other in-kind (61 ) (29 ) Changes in estimates (27 ) (16 ) Ending balance – December 31 $ 1,327 $ 1,864 At December 31, 2023, $0.1 billion of the liability balance remains subject to negotiations with customers. We expect to pay $0.6 billion in 2024 while the remaining amounts are expected to be liquidated by lower customer delivery payments. Environmental The following table summarizes changes in environmental remediation liabilities during the years ended December 31, 2023 and 2022. 2023 2022 Beginning balance – January 1 $ 752 $ 605 Reductions for payments made, net of recoveries (79 ) (43 ) Changes in estimates 171 190 Ending balance – December 31 $ 844 $ 752 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.

Product Warranties The following table summarizes changes in product warranty liabilities recorded during the years ended December 31, 2023 and 2022. 2023 2022 Beginning balance – January 1 $ 2,275 $ 1,900 Additions for current year deliveries 164 202 Reductions for payments made (320 ) (403 ) Changes in estimates 329 576 Ending balance – December 31 $ 2,448 $ 2,275 Commercial Aircraft Trade-In In conjunction with signing definitive agreements for the sale of new aircraft, we have entered into trade-in trade-in Trade-in Trade-in trade-in trade-in Financing Commitments Financing commitments related to aircraft on order, including options and those proposed in sales campaigns, and refinancing of delivered aircraft, totaled $17,003 and $16,105 as of December 31, 2023 and 2022.

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. Other Financial Commitments We have financial commitments to make additional capital contributions totaling $264 related to certain joint ventures over the next nine years. 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 and security agreements. Contingent liabilities on outstanding letters of credit agreements and surety bonds aggregated approximately $4,548 and $5,070 as of December 31, 2023 and 2022. 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, 2023 and 2022, the cash surrender value was $360 and $376 and the total loans were $334 and $346. 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, 2023 and 2022. Supply Chain Financing Programs The Company has supply chain financing programs in place under which participating suppliers may elect to obtain payment from an intermediary. The Company confirms the validity of invoices from participating suppliers and agrees to pay the intermediary an amount based on invoice totals. The majority of amounts payable under these programs are due within 30 to 90 days but may extend up to 12 months. At December 31, 2023 and 2022, Accounts payable included $2.9 billion and $2.5 billion payable to suppliers who have elected to participate in these programs. We do not believe that future changes in the availability of supply chain financing would have a significant impact on our liquidity. Government Assistance Certain states and localities in which we operate offer or have offered various business incentives related to investment and/or job creation. Between 2010 and 2016, we received cash grants totaling $346 related to our investment in operations in South Carolina. The grants were recorded in Accrued liabilities and are being amortized, primarily to inventory, over the useful life of the Property, plant and equipment extending through 2052. During 2023 and 2022, we amortized $10 and $11 to Inventories, and recorded a benefit of $12 and $5 in cost of sales. At December 31, 2023 and 2022, Inventories included a benefit of $62 and $64 and Accrued liabilities included a balance of $97 and $106. We are eligible to claim tax refunds from the State of Missouri and City of Irving, Texas primarily related to job creation and retention through 2031. During 2023 and 2022, we received $22 and $30 in cash and recorded a benefit of $28 and $21 in cost of sales. At December 31, 2023 and 2022, Other current assets includes receivables of $26 and $20. As of December 31, 2023, $60 of refunds, plus interest, is subject to clawback if we fail to meet certain conditions, including employment levels. We are eligible to claim cash grants through 2032 of up to $62, related to operations in Queensland, Australia. During 2023 and 2022, $5 and $7 cash was received and recorded as a benefit in cost of sales. At December 31, 2023, $4 is subject to clawback if we fail to meet certain conditions, including employment levels. Industrial Revenue Bonds (IRB) issued by St. Louis County and the city of St. Charles, Missouri were used to finance the purchase and/or construction of real and personal property at our St. Louis and St. Charles sites. Tax benefits associated with IRBs include twelve-year property tax abatements and sales tax exemptions from St. Louis County and a 22 year property tax abatement and sales tax exemption from the city of St. Charles. We record these properties on our Consolidated Statements of Financial Position. We have also purchased the IRBs, and therefore, are the bondholders as well as the borrower/lessee of the properties purchased with the IRB proceeds. The liabilities and IRB assets are equal and are reported net in the Consolidated Statements of Financial Position. As of December 31, 2023 and 2022, the assets and liabilities associated with the IRBs were $333 and $271. 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.

Certain of the fixed-price contracts are for the development of new products, services and related technologies. This development work scope is inherently uncertain and subject to significant variability in estimates of the cost and time required to complete the work by us and our suppliers.

Since 2016, the USAF has authorized ten low rate initial production (LRIP) lots for a total of 139 aircraft, including lots 9 and 10 that were authorized in 2023. The EMD contract and authorized LRIP lots total approximately $27 billion as of December 31, 2023. During 2022, we increased the reach-forward loss on the KC-46A KC-46A MQ-25 In the third quarter of 2018, we were awarded the MQ-25 MQ-25 T-7A In 2018, we were awarded the T-7A T-7A T-7A option to be exercised in 2025. During 2022, we increased the reach-forward loss by $552. During 2023, we increased the reach-forward loss by $275 primarily reflecting higher estimated production costs. At December 31, 2023, we had approximately $185 of capitalized precontract costs and $249 of potential termination liabilities to suppliers related to future production lots. Risk remains that we may record additional losses in future periods. Commercial Crew National Aeronautics and Space Administration (NASA) has contracted us to design and build the CST-100

The majority of employees that had participated in defined benefit pension plans have transitioned 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 three-fourths of those participants who are eligible for retiree 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.

Key information for our plans with ABO and PBO in excess of plan assets as of December 31 was as follows: 2023 2022 Accumulated benefit obligation $ 47,665 $ 48,134 Fair value of plan assets 41,666 42,491 2023 2022 Projected benefit obligation $ 48,320 $ 48,770 Fair value of plan assets 41,666 42,491 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, 2023 2022 2021 Discount rate: Pension 5.10 % 5.40 % 2.80 % Other postretirement benefits 5.00 % 5.30 % 2.50 % Expected return on plan assets 6.00 % 6.00 % 6.30 % Rate of compensation increase 4.30 % 4.30 % 4.30 % Interest crediting rates for cash balance plans 5.00 % 5.00 % 5.00 % 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. The present value of each plan’s benefits is calculated by applying the discount rates to projected benefit cash flows. 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 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, 2023, the MRVA was approximately $8,466 more than the fair market value of assets. Assumed health care cost trend rates were as follows: December 31, 2023 2022 2021 Health care cost trend rate assumed next year 5.50 % 5.50 % 4.50 % Ultimate trend rate 4.50 % 4.50 % 4.50 % Year that trend reaches ultimate rate 2028 2028 2021 Plan Assets Investment Strategy 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.

Global equity securities are invested in a diversified portfolio of U.S. and non-U.S. Private equity investment vehicles are primarily limited partnerships (LPs) that mainly invest in U.S. and non-U.S. Hedge fund investments seek to capitalize on inefficiencies identified across and within different asset classes or markets. Hedge fund strategy types include, but are not limited to, directional, event driven, relative value and long-short. Investment managers are retained for explicit investment roles specified by contractual investment guidelines. Certain investment managers are authorized to use 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 assets, derivative net notional amounts were 38.3% and 37.1% for fixed income, including to-be-announced In November 2020, the Company elected to contribute $3,000 of our common stock to the pension fund. An independent fiduciary was retained to manage and liquidate the stock over time at its discretion.

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 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 Real estate and real asset NAVs are based on the 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 Hedge fund NAVs are generally based on the 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. Investments in private equity, private debt, real estate, real assets and hedge funds are primarily calculated and reported by the General Partner, fund manager or third-party administrator. Additionally, some investments in fixed income and equity are made via commingled vehicles and are valued in a similar fashion. Pension assets invested in commingled and LP structures rely on the NAV of these investments as the practical expedient for the valuations.

The PRSUs granted under this program have a grant date fair value of $192.94 per unit. The award payout can range from 0% to 200% of the initial PRSU grant based on cumulative free cash flow achievement over the period January 1, 2024 through December 31, 2026 as compared to the target set at the start of the performance period, as well as the achievement of certain safety goals.

We believe we currently have adequate treasury shares to satisfy these issuances during 2024. Share-based plans expense is primarily included in Total costs and expenses and General and administrative expense, as well as a portion allocated to production as inventoried costs. The share-based plans expense and related income tax benefit were as follows: Years ended December 31, 2023 2022 2021 Restricted stock units and other awards $ 697 $ 726 $ 840 Income tax benefit (before consideration of valuation allowance) $ 157 $ 178 $ 148 Stock Options Options have been granted to our executive officers that are scheduled to vest and become exercisable three years after the grant date and expire ten years after the grant date. If an executive terminates employment because of retirement, layoff, disability, or death, the executive (or beneficiary) may receive some or all of their stock options depending on certain age and service conditions. The fair values of the stock options granted were estimated using a Monte-Carlo simulation model using the assumptions presented below. The model includes no expected dividend yield. Stock options granted during 2023 were not material. On February 16, 2022, we granted 348,769 premium-priced stock options to our executive officers as part of our long-term incentive program. These stock options have an exercise price equal to 120% of the fair market value of our stock on the date of grant. If certain performance measures are met, the exercise price is reduced to 110% of the grant date fair market value of our stock. On February 17, 2021, we granted 342,986 premium-priced stock options to our executive officers as part of our long-term incentive program. These stock options have an exercise price equal to 120% of the fair market value of our stock on the date of grant. During 2021, we also granted 148,322 stock options to certain executives, of which 40,322 had an exercise price equal to 120% of the fair market value of our stock on the date of grant, and the remaining 108,000 had an exercise price equal to the fair market value of our stock on the date of grant.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 17 – Fair Value Measurements 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. 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. June 30, 2024 December 31, 2023 Total Level 1 Level 2 Total Level 1 Level 2 Assets Money market funds $ 2,101 $ 2,101 $ 1,514 $ 1,514 Available-for-sale Commercial paper 251 $ 251 291 $ 291 Corporate notes 247 247 183 183 U.S. and local government agencies 17 17 25 25 Other equity investments 57 57 44 44 Derivatives 78 78 122 122 Total assets $ 2,751 $ 2,158 $ 593 $ 2,179 $ 1,558 $ 621 Liabilities Derivatives ($ 67 ) ($ 67 ) ($ 58 ) ($ 58 ) Other (17 ) (17 ) Total liabilities ($ 84 ) ($ 84 ) ($ 58 ) ($ 58 ) Money market funds, available-for-sale Derivatives include foreign currency and commodity 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. Certain assets have been measured at fair value on a nonrecurring basis. The following table presents the nonrecurring losses recognized for the six months ended June 30 due to long-lived asset impairment and the fair value of the related assets as of the impairment date: 2024 2023 Fair Total Losses Fair Total Investments ($ 17 ) ($ 11 ) Operating lease equipment $ 15 (5 ) Property, plant and equipment (9 ) Other assets (3 ) (1 ) Total $ 15 ($ 34 ) ($ 12 ) Level 3 Investments and Other assets were primarily valued using an income approach based on the discounted cash flows associated with the underlying assets. Level 2 Property, plant and equipment were valued based on a third-party valuation using a combination of income and market approaches and adjusted for as-is For Level 3 assets that were measured at fair value on a nonrecurring basis during the period ended June 30, 2024, 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 Value Valuation Technique Unobservable Input Range Median or Average Operating lease equipment $15 Market approach Aircraft value publications Aircraft condition adjustments $21 – $27(1) Median $23 (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: June 30, 2024 Carrying Amount Total Fair Value Level 1 Level 2 Level 3 Assets Notes receivable, net $ 760 $ 778    $ 766 $ 12 Liabilities Debt, excluding finance lease obligations (57,669 ) (53,642 ) (53,642 ) December 31, 2023 Carrying Total Fair Level 1 Level 2 Level 3 Assets Notes receivable, net $ 257 $ 270    $ 270    Liabilities Debt, excluding finance lease obligations (52,055 ) (51,039 ) (51,039 ) The fair value of notes receivables classified as Level 2 is 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 notes receivables classified as Level 3 is based on our best estimate using available counterparty financial data. 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. With regard to other financial instruments with off-balance as the Condensed Consolidated Statements of Financial Position, approximate their fair value at June 30, 2024 and December 31, 2023. 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).	Note 20 – Fair Value Measurements 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.

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. 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: December 31, 2023 Carrying Total Fair Level 1 Level 2 Level 3 Assets Notes receivable, net $ 257 $ 270 $ 270 Liabilities Debt, excluding finance lease obligations (52,055 ) (51,039 ) (51,039 ) December 31, 2022 Carrying Total Fair Level 1 Level 2 Level 3 Assets Notes receivable, net $ 385 $ 403 $ 403 Liabilities Debt, excluding finance lease obligations (56,794 ) (52,856 ) (52,856 ) The fair values of 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. With regard to other financial instruments with off-balance 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 receivable, Unbilled receivables, Other current assets, 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, 2023 and 2022. 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 [Abstract]
Legal Proceedings	Note 18 – Legal Proceedings Various legal proceedings, claims and investigations related to products, contracts, employment and other matters are pending against us. In addition, we are subject to various government inquiries and 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 U.S. government regulations, a company, or one or more of its operating divisions or subdivisions, can also be suspended or debarred from government contracts, have certain of its production certificates suspended or revoked, or lose its export privileges, based on the results of investigations. We believe, based upon current information, that the outcome of any currently pending legal proceeding, claim, or government dispute, inquiry or investigation will not have a material effect on our financial position, results of operations or cash flows. With respect to the matters set forth below, we cannot reasonably estimate a range of loss in excess of recorded amounts, if any. Multiple legal actions and inquiries were initiated as a result of the October 29, 2018 accident of Lion Air Flight 610 and the March 10, 2019 accident of Ethiopian Airlines Flight 302. On January 7, 2021, we entered into a Deferred Prosecution Agreement (DPA) with the U.S. Department of Justice (the Department) relating to the Department’s investigation into us regarding the evaluation of the 737 MAX by the Federal Aviation Administration (the Investigation). Among other obligations, the DPA includes a three-year reporting period, which ended earlier this year. On May 14, 2024, the Department notified us of its determination that we did not fulfill our obligations under the DPA and that the Department would not move to dismiss the information. On July 24, 2024, we and the Department filed a plea agreement with the U.S. District Court for the Northern District of Texas (the Court) to resolve the Investigation. If approved by the Court, under the terms of the agreement, Boeing would agree to plead guilty to the charge that was the basis for the DPA; would pay an additional fine of $244; would commit to invest at least $455 in compliance, quality and safety programs over a three-year period; and would agree to the appointment of an independent compliance monitor for three years. We are actively engaging with the U.S. Department of Defense regarding potential impacts on our business with the U.S. government and are assessing other related risks. Multiple legal actions were initiated as a result of the January 5, 2024 Alaska Airlines Flight 1282 accident. We are also subject to multiple governmental and regulatory investigations and inquiries relating to the Alaska Airlines Flight 1282 accident and our commercial airplanes business. We cannot reasonably estimate a range of loss, if any, not covered by available insurance that may result given the current status of pending lawsuits, investigations and inquiries related to the 737 program. During 2019, we entered into agreements with Embraer S.A. (Embraer) to establish joint ventures that included the commercial aircraft and services operations of Embraer, of which we were expected to acquire an 80 percent ownership stake for $4,200, as well as a joint venture to promote and develop new markets for the C-390	Note 21 – Legal Proceedings Various legal proceedings, claims and investigations related to products, contracts, employment and other matters are Multiple legal actions and inquiries were initiated as a result of the October 29, 2018 accident of Lion Air Flight 610 and the March 10, 2019 accident of Ethiopian Airlines Flight 302. On January 7, 2021, we entered into a Deferred Prosecution Agreement (DPA) with the U.S. Department of Justice that resolved the Department of Justice’s investigation into us regarding the evaluation of the 737 MAX by the Federal Aviation Administration (FAA). Among other obligations, the DPA includes a three-year reporting period, which ended earlier this month. The Department is currently considering whether we fulfilled our obligations under the DPA and whether to move to dismiss the information, which motion will require court approval.

See page F-70 for the Summary of Business Segment Data, which is an integral part of this note. BCA develops, produces and markets commercial jet aircraft principally to the commercial airline industry worldwide. Revenue on commercial aircraft contracts is recognized at the point in time when an aircraft is completed and accepted by the customer. BDS engages in the research, development, production and modification of the following products and related services: manned and unmanned military aircraft and weapons systems, surveillance and engagement, strategic defense and intelligence systems, satellite systems and space exploration. BDS revenue is generally recognized over the contract term (over time) as costs are incurred BGS provides parts, maintenance, modifications, logistics support, training, data analytics and information-based services to commercial and government customers worldwide. BGS segment revenue and costs include certain products and services The following tables present BCA, BDS and BGS revenues from contracts with customers disaggregated in a number of ways, such as geographic location, contract type and the method of revenue recognition. We believe these best depict how the nature, amount, timing and uncertainty of our revenues and cash flows are affected by economic factors. BCA revenues by customer location consisted of the following: (Dollars in millions) Six months ended Three months ended 2024 2023 2024 2023 Revenue from contracts with customers: Europe $ 1,547 $ 3,393 $ 777 $ 2,038 Asia 4,393 2,355 2,280 1,549 Middle East 1,174 1,466 406 750 Other non-U.S. 754 1,082 344 729 Total non-U.S. 7,868 8,296 3,807 5,066 United States 3,158 7,175 2,173 3,740 Estimated potential concessions and other considerations to 737 MAX customers, net of insurance recoveries (443 ) 26 26 Total revenues from contracts with customers 10,583 15,497 5,980 8,832 Intersegment revenues eliminated on consolidation 73 47 23 8 Total segment revenues $ 10,656 $ 15,544 $ 6,003 $ 8,840 Revenue recognized on fixed-price contracts 100 % 100 % 100 % 100 % Revenue recognized at a point in time 99 % 99 % 99 % 99 % BDS revenues on contracts with customers, based on the customer’s location, consisted of the following: (Dollars in millions) Six months ended Three months ended 2024 2023 2024 2023 Revenue from contracts with customers: U.S. customers $ 9,963 $ 10,338 $ 4,519 $ 5,028 Non-U.S. 3,008 2,368 1,502 1,139 Total segment revenue from contracts with customers $ 12,971 $ 12,706 $ 6,021 $ 6,167 Revenue recognized over time 99 % 99 % 99 % 99 % Revenue recognized on fixed-price contracts 55 % 59 % 52 % 57 % Revenue from the U.S. government (1) 90 % 90 % 89 % 90 % (1) Includes revenues earned from foreign military sales through the U.S. government.

Backlog Our total backlog includes contracts that we and our customers are committed to perform. The value in backlog represents the estimated transaction prices on performance obligations to our customers for which work remains to be performed. Backlog is converted into revenue, primarily based on the cost incurred or at delivery and acceptance of products, depending on the applicable revenue recognition model. Our backlog at June 30, 2024 was $515,874. We expect approximately 24% to be converted to revenue through 2025 and approximately 69% through 2028, with the remainder thereafter. There is significant uncertainty regarding the timing of when backlog will convert into revenue. We may experience reductions to backlog and/or significant order cancellations due to production disruptions, and/or further delays to entry into service of the 777X, 737-7 737-10. Unallocated Items, Eliminations and Other Unallocated items, eliminations and other include common internal services that support Boeing’s global business operations and eliminations of certain sales between segments. We generally allocate costs to business segments based on the U.S. Government Cost Accounting Standards (CAS). Components of Unallocated items, eliminations and other (expense)/income are shown in the following table. Six months ended Three months ended 2024 2023 2024 2023 Share-based plans $ 53 ($ 38 ) $ 43 $ 14 Deferred compensation (49 ) (96 ) (19 ) (42 ) Amortization of previously capitalized interest (46 ) (47 ) (23 ) (24 ) Research and development expense, net (188 ) (149 ) (99 ) (73 ) Eliminations and other unallocated items (716 ) (466 ) (536 ) (211 ) Unallocated items, eliminations and other ($ 946 ) ($ 796 ) ($ 634 ) ($ 336 ) Eliminations and other unallocated items for the six and three months ended June 30, 2024 includes an earnings charge of $244 that reflects a fine that would be paid if an agreement with the U.S. Department of Justice is approved by the federal district court. For additional discussion, see Note 18 to our Condensed Consolidated Financial Statements. Pension and Other Postretirement Benefit Expense Pension costs are allocated to BDS and BGS businesses supporting government customers using CAS, which employ different actuarial assumptions and accounting conventions than GAAP. These costs are allocable to government contracts. Other postretirement benefit costs are allocated to business segments based on CAS, which is generally based on benefits paid. FAS/CAS service cost adjustment represents the difference between the Financial Accounting Standards (FAS) pension and postretirement service costs calculated under GAAP and costs allocated to the business segments. Non-operating Six months ended Three months ended 2024 2023 2024 2023 Pension FAS/CAS service cost adjustment $ 460 $ 445 $ 230 $ 222 Postretirement FAS/CAS service cost adjustment 144 137 72 69 FAS/CAS service cost adjustment $ 604 $ 582 $ 302 $ 291 Assets Segment assets are summarized in the table below: June 30 December 31 Commercial Airplanes $ 83,478 $ 77,047 Defense, Space & Security 16,239 14,921 Global Services 16,473 16,193 Unallocated items, eliminations and other 26,530 28,851 Total $ 142,720 $ 137,012 Assets included in Unallocated items, eliminations and other primarily consist of Cash and cash equivalents, Short-term and other investments, tax assets, capitalized interest and assets managed centrally on behalf of the three principal business segments and intercompany eliminations.	Note 22 – Segment and Revenue Information Segment results reflect the realignment of the Boeing Customer Financing team and portfolio into the BCA segment during the first quarter of 2023. Interest and debt expense now includes interest and debt expense previously attributable to Boeing Cost of Sales Our primary profitability measurement to review segment operating results is Loss from operations. We operate in three reportable segments: BCA, BDS, and BGS. All other activities fall within Unallocated items, eliminations and other. See page F-6 for the Summary of Business Segment Data, which is an integral part of this note. BCA develops, produces and markets commercial jet aircraft principally to the commercial airline industry worldwide. Revenue on commercial aircraft contracts is recognized at the point in time when an aircraft is completed and accepted by the customer. BDS engages in the research, development, production and modification of the following products and related services: manned and unmanned military aircraft and weapons systems, surveillance and engagement, strategic defense and intelligence systems, satellite systems and space exploration. BDS revenue is generally recognized over the contract term (over time) as costs are incurred. BGS provides parts, maintenance, modifications, logistics support, training, data analytics and information-based services to commercial and government customers worldwide. BGS segment revenue and costs include certain products and services provided to other segments. Revenue on commercial spare parts contracts is recognized at the point in time when a spare part is delivered to the customer. Revenue on other contracts is generally recognized over the contract term (over time) as costs are incurred. While our principal operations are in the United States, Canada and Australia, some key suppliers and subcontractors are located in Europe and Japan. Revenues, including foreign military sales, are reported by customer location and consisted of the following: Years ended December 31, 2023 2022 2021 Europe $ 10,520 $ 7,916 $ 8,967 Asia 10,013 8,393 5,845 Middle East 6,594 5,047 4,653 Oceania 1,655 1,576 1,147 Canada 1,256 1,612 969 Africa 825 418 239 Latin America, Caribbean and other 1,524 2,412 1,376 Total non-U.S. 32,387 27,374 23,196 United States 45,380 39,218 39,076 Estimated potential concessions and other considerations to 737 MAX customers 27 16 14 Total revenues $ 77,794 $ 66,608 $ 62,286 Revenues from the U.S. government (including foreign military sales through the U.S. government), primarily recorded at BDS and BGS, represented 37%, 40% and 49% of consolidated revenues for 2023, 2022 and 2021, respectively. Approximately 4% of operating assets were located outside the United States as of December 31, 2023 and 2022. The following tables present BCA, BDS and BGS revenues from contracts with customers disaggregated in a number of ways, such as geographic location, contract type and the method of revenue recognition. We believe these best depict how the nature, amount, timing and uncertainty of our revenues and cash flows are affected by economic factors. BCA revenues by customer location consisted of the following: Years ended December 31, 2023 2022 2021 Revenue from contracts with customers: Asia $ 6,328 $ 4,488 $ 2,816 Europe 6,172 4,085 4,387 Middle East 4,311 2,003 1,098 Other non-U.S. 2,431 3,042 1,683 Total non-U.S. 19,242 13,618 9,984 United States 14,501 12,275 9,614 Estimated potential concessions and other considerations to 737 MAX customers 27 16 14 Total revenues from contracts with customers 33,770 25,909 19,612 Intersegment revenues, eliminated on consolidation 131 117 102 Total segment revenues $ 33,901 $ 26,026 $ 19,714 Revenue recognized on fixed-price contracts 100 % 100 % 100 % Revenue recognized at a point in time 99 % 99 % 99 % BDS revenues on contracts with customers, based on the customer’s location, consisted of the following: Years ended December 31, 2023 2022 2021 Revenue from contracts with customers: U.S. customers $ 20,051 $ 17,144 $ 19,869 Non-U.S. 4,882 6,018 6,671 Total segment revenue from contracts with customers $ 24,933 $ 23,162 $ 26,540 Revenue recognized over time 99 % 99 % 99 % Revenue recognized on fixed-price contracts 58 % 60 % 68 % Revenue from the U.S. government(1) 91 % 89 % 89 % (1) Includes revenues earned from foreign military sales through the U.S. government.

Earnings in Equity Method Investments During the years ended December 31, 2023, 2022, and 2021, our share of income from equity method investments was $70, $56, and $40, respectively. In 2023 and 2021, earnings in equity method investments were primarily driven by investments held at our BDS segment. In 2022, earnings in equity method investments were primarily driven by investments held in Unallocated items, eliminations and other. Backlog Our total backlog includes contracts that we and our customers are committed to perform. The value in backlog represents the estimated transaction prices on performance obligations to our customers for which work remains to be performed. Backlog is converted into revenue, primarily based on the cost incurred or at delivery and acceptance of products, depending on the applicable revenue recognition model. Our backlog at December 31, 2023 was $520,195. We expect approximately 16% to be converted to revenue through 2024 and approximately 62% through 2027, with the remainder thereafter. There is significant uncertainty regarding the timing of when backlog will convert into revenue due to timing of 737 and 787 deliveries from inventory and timing of entry into service of the 777X, 737-7 737-10. Unallocated Items, Eliminations and other Unallocated items, eliminations and other include common internal services that support Boeing’s global business operations and eliminations of certain sales between segments. We generally allocate costs to business segments based on the U.S. Government Cost Accounting Standards (CAS).

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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. As described in Note 22, we now operate in three reportable segments: Commercial Airplanes (BCA), Defense, Space & Security (BDS), and Global Services (BGS). As a result, prior period amounts have been reclassified to conform to current period presentation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Goodwill	Goodwill We performed our annual goodwill impairment test as of April 1, 2024, using a qualitative assessment. We determined the fair value of each of our reporting units substantially exceeded their respective carrying values.
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.
Long-term Contracts	Long-term Contracts Substantially all contracts at our Defense, Space & Security (BDS) segment and certain contracts at our Global Services (BGS) segment are long-term contracts with the U.S. government and other customers that generally extend over several years. Changes in estimated revenues, cost of sales, and the related effect on operating income are recognized using a cumulative catch-up percentage-of-completion. The table below reflects the impact of net cumulative catch-up (In millions – except per share amounts) Six months ended Three months ended 2024 2023 2024 2023 Decrease to Revenue ($ 965 ) ($ 782 ) ($ 747 ) ($ 470 ) Increase to Loss from operations ($ 1,700 ) ($ 1,348 ) ($ 1,334 ) ($ 830 ) Increase to Diluted loss per share ($ 2.62 ) ($ 1.43 ) ($ 2.06 ) ($ 0.51 )	Revenue and Related Cost Recognition Commercial aircraft contracts Payments for commercial aircraft sales are received in accordance with the customer agreement, which generally includes a deposit upon order and additional payments in accordance with a payment schedule, with the balance being due immediately prior to or at aircraft delivery. Advances and progress billings (contract liabilities) are normal and customary for commercial aircraft contracts and not considered a significant financing component as they are intended to protect us from the other party failing to adequately complete some or all of its obligations under the contract. Long-term contracts For each long-term contract, we determine the transaction price based on the consideration expected to be received. We allocate the transaction price to each distinct performance obligation to deliver a good or service, or a collection of goods and/or services, based on the relative standalone selling prices. A long-term contract will typically represent a single distinct performance obligation due to the highly interdependent and interrelated nature of the underlying goods and/or services and the significant service of integration that we provide. While the scope and price on certain long-term contracts may be modified over their life, the transaction price is based on current rights and obligations under the contract and does not include potential modifications until they are agreed upon with the customer. When applicable, a cumulative adjustment or separate recognition for the additional scope and price may result. Long-term contracts can be negotiated with a fixed price or a price in which we are reimbursed for costs incurred plus an agreed upon profit. The Federal Acquisition Regulations provide guidance on the types of cost that will be reimbursed in establishing the price for contracts with the U.S. government. Certain long-term contracts include in the transaction price variable consideration, such as incentive and award fees, if specified targets are achieved. The amount included in the transaction price represents the expected value, based on a weighted probability, or the most likely amount. Long-term contract revenue is recognized over the contract term (over time) as the work progresses, either as products are produced or as services are rendered. We generally recognize revenue over time as we perform on long-term contracts because of continuous transfer of control to the customer. For U.S. government contracts, this continuous transfer of control to the customer is supported by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay us for costs incurred plus a reasonable profit and take control of any work in process. Similarly, for non-U.S. The accounting for long-term contracts involves a judgmental process of estimating total revenues, costs and profit for each performance obligation. Cost of sales is recognized as incurred. The amount reported as revenues is determined by adding a proportionate amount of the estimated profit to the amount reported as cost of sales. Recognizing revenue as costs are incurred provides an objective measure of progress on the long-term contract and thereby best depicts the extent of transfer of control to the customer. For long-term contracts for which revenue is recognized over time, changes in estimated revenues, cost of sales and the related effect on operating income are recognized using a cumulative catch-up percentage-of-completion. The table below reflects the impact of net cumulative catch-up 2023 2022 2021 Decrease to Revenue ($ 1,706 ) ($ 2,335 ) ($ 379 ) Increase to Loss from operations ($ 2,943 ) ($ 5,253 ) ($ 880 ) Increase to Diluted loss per share ($ 5.43 ) ($ 8.88 ) ($ 1.28 ) Significant adjustments during the three years ended December 31, 2023 included losses on VC-25B, KC-46A MQ-25, T-7A F-15 Due to the significance of judgment in the estimation process, changes in underlying assumptions/estimates, internal and supplier performance, inflationary trends, or other circumstances may adversely or positively affect financial performance in future periods. Payments under long-term contracts may be received before or after revenue is recognized. The U.S. government customer typically withholds payment of a small portion of the contract price until contract completion. Therefore, long-term contracts typically generate Unbilled receivables (contract assets) but may generate Advances and progress billings (contract liabilities). Long-term contract Unbilled receivables and Advances and progress billings are not considered a significant financing component because they are intended to protect either the customer or the Company in the event that some or all of the obligations under the contract are not completed. Commercial spare parts contracts Other service revenue contracts Concession sharing arrangements Unbilled receivables and advances and progress billings Financial services revenue the leased equipment, and any 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. For notes receivable, we record financing receivables 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. Income recognition is generally suspended for financing receivables that are uncollectible. We determine that a financing receivable is uncollectible 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. We determine a financing receivable is past due when cash has not been received upon the due date specified in the contract. We evaluate the collectability of financing receivables at commencement and on a recurring basis. If a financing receivable is determined to be uncollectible, the customer is categorized as non-accrual non-accrual non-accrual non-accrual non-accrual 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 Financing receivables and operating lease equipment, net, are recorded at cost and depreciated to an estimated residual value using the straight-line method over the period that we project we will hold the asset. We periodically review our estimates of residual value and recognize forecasted changes by prospectively adjusting depreciation expense. We record assets held for sale at the lower of carrying value or fair value less costs to sell. We evaluate for impairment assets under operating leases when events or changes in circumstances indicate that the expected undiscounted cash flow from the asset may be less than the carrying value. 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. Reinsurance revenue
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 long-term 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, net included bid and proposal costs of $188, $217 and $213 in 2023, 2022 and 2021, 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 U.S. federal, state and local, and non-U.S. The accounting for uncertainty in income taxes requires a more-likely than-not Tax-related We also assess the likelihood that we will be able to recover our deferred tax assets against future sources of taxable income and reduce the carrying amounts of deferred tax assets by recording a valuation allowance if, based on the available evidence, it is more likely than not that all or a portion of such assets will not be realized. Changes in our estimates and judgments regarding realization of deferred tax assets may result in an increase or decrease to our tax expense and/or other comprehensive income, which would be recorded in the period in which the change occurs.
Postretirement Plans		Postretirement Plans Many of our employees have earned benefits under defined benefit pension plans. The majority of employees that had participated in defined benefit pension plans have transitioned 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). 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 expected future lifetime of participants. 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
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
Inventories		Inventories Inventoried costs on commercial aircraft programs and long-term contracts include direct engineering, production and tooling and other non-recurring 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 aircraft 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 our BCA segment and general stock materials are stated at cost not in excess of net realizable value. Spare parts inventory is stated at lower of average unit cost or net realizable value. 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.
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
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 4 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’ 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.
Leases		Leases Operating lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. We use our estimated incremental borrowing rate in determining the present value of lease payments. Variable components of the lease payments such as fair market value adjustments, utilities and maintenance costs are expensed as incurred and not included in determining the present value. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term. We have real property lease agreements with lease and non-lease
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 quantitative test. 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 quantitative test is then performed; otherwise, no further testing is required. For operations where the quantitative test is used, we compare the carrying value of net assets to the estimated fair value of the related operations. If the fair value is determined to be less than carrying value, the shortfall up to the carrying value of the goodwill represents the amount of goodwill impairment. Indefinite-lived intangibles consist of a brand and trade name and in-process Our finite-lived acquired intangible assets are amortized on a straight-line basis over their estimated useful lives as follows: developed technology, from 4 to 14 years; product know-how,
Investments		Investments Time deposits are held-to-maturity Available-for-sale Available-for-sale available-for-sale Available-for-sale 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%. The cumulative earnings approach is used for cash flow classification of distributions received from equity method investments. Other Equity investments are recorded at fair value, with gains and losses recorded through net earnings. Equity investments without readily determinable fair value are measured at cost, less impairments, plus or minus observable price changes. Equity investments without readily determinable fair value are assessed for impairment quarterly. We classify investment income and loss on our Consolidated Statements of Operations based on whether the investment is operating or non-operating Non-operating non-strategic non-operating
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 our cash flow hedges, the derivative’s gain or loss is initially reported in comprehensive income and is subsequently reclassified into earnings in the same period(s) during which the hedged forecasted transaction affects earnings. We have agreements to purchase and sell aluminum to address long-term strategic sourcing objectives and non-U.S.
Allowances for Losses on Certain Financial Assets		Allowances for Losses on Certain Financial Assets We establish allowances for credit losses on accounts receivable, unbilled receivables, financing receivables and certain other financial assets. The adequacy of these allowances is assessed quarterly through consideration of factors such as customer credit ratings, bankruptcy filings, published or estimated credit default rates, age of the receivable, expected loss rates and collateral exposures. Collateral exposure is the excess of the carrying value of a financial asset over the fair value of the related collateral. We determine the creditworthiness of our customers by assigning internal credit ratings based upon publicly available information and information obtained directly from the customers. Our rating categories are comparable to those used by major credit rating agencies. Financing receivables are collateralized by security in the related asset. 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 collateral. 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. 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. 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.
Commercial Aircraft Trade-in Commitments		Commercial Aircraft Trade-in In conjunction with signing a definitive agreement for the sale of new commercial aircraft (Sale Aircraft), we have entered into trade-in Exposure related to trade-in (1) adjustments to revenue for the difference between the contractual trade-in trade-in (2) charges to cost of products for adverse changes in the fair value of trade-in trade-in The fair value of trade-in trade-in Trade-in
Warranties		Warranties In conjunction with certain product sales, we provide warranties that cover factors such as non-conformance 4-year two-year We provide guarantees to certain commercial aircraft 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 estimates to complete the related programs.
Supplier Penalties		Supplier Penalties We may incur penalties to suppliers under certain circumstances such as a contract termination. We record an accrual for supplier penalties when an event occurs that makes it probable we will incur a supplier penalty and the amount is reasonably estimable.
Guarantees		Guarantees At the inception of a guarantee, we record a liability in Accrued liabilities for the fair value of the guarantee. 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. We also recognize a liability for the expected contingent loss at inception and adjust it each quarter.
Earnings Per Share	Basic and diluted earnings per share are computed using the two-class Basic earnings per share is calculated by taking net earnings attributable to Boeing Shareholders, 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 attributable to Boeing Shareholders, less earnings available to participating securities, divided by the diluted weighted average common shares outstanding. Diluted weighted average common shares outstanding is calculated using the treasury stock method.	Basic and diluted earnings per share are computed using the two-class 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 attributable to Boeing Shareholders, less earnings available to participating securities, divided by the basic weighted average common shares outstanding.
