ITEM 9A. CONTROLS AND PROCEDURES Evaluation of Disclosure Control and Procedures UAL and United each maintain controls and procedures that are designed to ensure that information required to be disclosed in the reports filed or submitted by UAL and United to the SEC is recorded, processed, summarized and reported, within the time periods specified by the SEC's rules and forms, and is accumulated and communicated to management including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. The management of UAL and United, including the Chief Executive Officer and Chief Financial Officer, performed an evaluation to conclude with reasonable assurance that UAL's and United's disclosure controls and procedures were designed and operating effectively to report the information each company is required to disclose in the reports they file with the SEC on a timely basis. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer of UAL and United have concluded that as of December 31, 2020, disclosure controls and procedures were effective. Changes in Internal Control over Financial Reporting during the Quarter Ended December 31, 2020 During the three months ended December 31, 2020, there was no change in UAL's or United's internal control over financial reporting that materially affected, or is reasonably likely to materially affect, their internal control over financial reporting. 108 Table of Contents REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Stockholders and Board of Directors of United Airlines Holdings, Inc. Opinion on Internal Control over Financial Reporting We have audited United Airlines Holdings, Inc.'s (the "Company") internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the "COSO criteria"). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the consolidated financial statements as of and for the year ended December 31, 2020 of the Company and our report dated March 1, 2021 expressed an unqualified opinion thereon. Basis for Opinion The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management Report on Internal Control over Financial Reporting in Item 9A. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Ernst & Young LLP Chicago, Illinois March 1, 2021 109 Table of Contents United Airlines Holdings, Inc.

OTHER INFORMATION. 2021 Executive Compensation Program On February 25, 2021, the Compensation Committee (the "Committee") of the Board of Directors of United Airlines Holdings, Inc. (the "Company") approved the Company's 2021 executive compensation program ("2021 Program"). The 2021 Program is designed to be aligned with the Company's recovery efforts from the COVID-19 pandemic and the related impacts on the global economy and the travel industry in particular. As described further below, the recovery design of the 2021 Program includes short-term and long-term incentive awards. The 2021 Program maintains salary and compensation levels linked to short-term performance goals but significantly reduces the intended levels of long-term equity incentives granted to our executives in order to comply with the compensation limits of the CARES Act (as described below). As a result of this reduction in long-term equity incentives, the compensation component levels under the 2021 Program differ as compared to our traditional and intended compensation levels. As previously disclosed, in April 2020, the Company entered into a Payroll Support Program Agreement (the "First PSP Agreement") with the United States Department of the Treasury (the "U.S. Treasury Department") under the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"); in September 2020, the Company entered into a loan agreement with the U.S. Treasury Department (the "Term Loan Facility") pursuant to the loan program established under the CARES Act; and, in January 2021, the Company and the U.S. Treasury Department entered into the Payroll Support Program Extension Agreement (together with the First PSP Agreement, the "PSP Agreement"). As a condition of the PSP Agreement and the Term Loan Facility, the Company is subject to restrictions on the amount of total compensation that it can provide to certain employees, including each of the Company's named executive officers. These compensation restrictions continue until the later of (i) October 1, 2022 and (ii) one year after full repayment of all loans under the Term Loan Facility, which has a maturity date of September 26, 2025 (such period is referred to herein as the "CARES Act restricted period"). The annual total target compensation levels for our executives are set with reference to market practices of a peer group of companies and the benchmarking results are balanced with additional factors, such as each executive's experience, knowledge, skills, roles, and contributions to the Company. The Committee also considers internal pay parity among our executives. As a result of the CARES Act limitations on executive compensation, the Company is prohibited from providing our executives the full value of the intended compensation levels during the CARES Act restricted period. The 2021 Program is designed to motivate and retain our executives while complying with the compensation limits under the CARES Act. The compensation packages of our executives also were significantly reduced during 2020. As previously disclosed, Scott Kirby, our CEO, and Brett Hart, our President, each waived 100% of his 2020 base salary for portions of 2020 in recognition of the impact of the COVID-19 pandemic on the Company's business, and to lead by example. In addition, no payments were made under our 2020 Annual Incentive Program ("AIP"). The total salary amounts waived during 2020 were as follows (including reference to the percent of total annual salary that was waived for 2020): Mr. Kirby—$784,470 (82%) Mr. Hart—$545,737 (70%); and Mr. Gerald Laderman (our Executive Vice President and Chief Financial Officer)—$151,057 (21%). The target level of the 2020 AIP awards, for which no payments were made, were as follows: Mr. Kirby—$2,500,000; Mr. Hart—$1,356,250; and Mr. Laderman—$758,500. Short-term Incentives. On February 25, 2021, the Committee authorized short-term performance-based restricted stock unit ("RSU") awards ("Recovery Performance RSUs") under the Company's 2017 Incentive Compensation Plan (the "2017 Plan") in lieu of the cash-based payment structure of the 2020 AIP. Under the Recovery Performance RSUs, the Committee established short-term performance goals based on financial and customer satisfaction metrics that are deemed critical to the Company's success as it emerges from the worst crisis in the history of the aviation industry. The equity design of the Recovery Performance RSUs places emphasis on Company stock price performance and is designed to further support alignment of interests between our executives and stockholders. The Recovery Performance RSUs may be granted to officers and employees of United Airlines, Inc. ("United") or any subsidiary of United. Generally, a recipient of a Recovery Performance RSU award must remain continuously employed from the date of grant through the last day of the performance period in order to be eligible for vesting of the award. However, if the recipient's employment is terminated by reason of death or disability, then the award will vest on a pro-rated basis (based on the number of days worked during the performance period and assuming achievement of the target level). Long-term Equity Incentives. The Committee sets the intended long-term equity compensation levels as an element of the annual total target compensation package based on the peer benchmarking results and other factors referenced above. However, in designing the 2021 Program, the Committee determined that it was appropriate to implement the required CARES Act compensation limits through reductions to the target grant level of the long-term equity awards. The 2021 reductions to the long-term equity awards to comply with the CARES Act limits are detailed in the table below. 111 Table of Contents Name Intended LTI Equity Award Level Actual LTI Equity Award Level (1) Reduction For CARES Act Limit J. Scott Kirby $10,000,000 $6,230,000 $3,770,000 Brett J. Hart $5,812,500 $1,256,000 $4,556,500 Gerald Laderman $2,718,750 $1,665,000 $1,053,750 The entire 2021 LTI equity award for Mr. Hart and a portion of the 2021 LTI equity award ($1,574,000) for Mr. Kirby will not be granted until a later date in accordance with the requirements of the CARES Act, which counts and restricts total compensation on a rolling 12-month basis. As noted above, in order to support continued alignment with the Company's stockholders, the short-term incentive component is being delivered entirely in equity. In addition, while the short-term component of the 2021 Program emphasizes performance goals deemed critical to the Company's emergence from the COVID-19 pandemic, the 2021 long-term incentive retains the time-vested equity component included in the Company's long-term incentive design in prior years. The time-vested equity component enhances stability of the long-term incentive by reducing volatility (as compared to performance-based awards), which is expected to enhance retention value, while assuring that a significant portion of compensation is directly linked to the Company's stock price performance. Vesting of the time-vested RSUs is subject to the employee's continued employment with the Company or its subsidiaries from the date of grant through each vesting date (except as otherwise provided by the Committee or as provided in the 2017 Plan). The time-vested awards under the 2021 Program generally vest in six-month increments over a two-year period (on August 31 st and February 28th). The Committee established this vesting schedule in consideration of the significant reduction in the long-term equity incentives under the 2021 Program as compared to the intended levels under the Company's traditional total compensation design. In addition, this vesting schedule is balanced by the extended vesting period of the long-term contingent cash awards (described below), which include a vesting condition that may extend for more than five years. Consistent with our prior long-term incentive design, if the employee remains continuously employed by the Company or an affiliate from the date of grant until the date upon which a qualifying event (which is generally a termination of employment within two years following a change of control of the Company under circumstances entitling the employee to a cash severance payment) occurs, then on the date of such qualifying event the employee's rights with respect to all RSUs that are not then vested will become vested and all restrictions on such RSUs will lapse. Further, if the employee's employment is terminated by reason of death or disability, then all RSUs that are not then vested will fully vest. Long-term Contingent Cash Awards. On February 25, 2021, the Committee also approved long-term contingent cash awards (the "Long-Term Cash Awards") in recognition of the Company's need to reward and retain its management team as it continues to navigate the Company's responses to the COVID-19 pandemic. The Committee approved Long-Term Cash Awards to Messrs. Kirby, Hart, and Laderman with a contingent payment opportunity equal to three times the executive's base salary level at the time of grant. Under the terms of the Long-Term Cash Awards, payment of the award is contingent upon the recipient's continued employment with the Company through the later of (i) three years from the date of award or (ii) the expiration of the CARES Act restricted period. If the recipient's employment is terminated by reason of death or disability, then the Long-Term Cash Award is payable in full to the recipient or his or her estate. In making the determination to grant the Long-Term Cash Awards, the Committee considered concerns related to the need to retain and reward our management team throughout the current crisis, considerations related to compensation benchmarking and internal and external pay parity, and management's voluntary waivers of significant salary amounts in 2020. The Long-Term Cash Awards are intended to enhance our ability to retain our management team during this time of unprecedented challenges for the Company and the airline industry as a whole, particularly as our management team has marketable skills that are highly valued and transferable to other companies, including companies in industries that have not been as adversely impacted by COVID-19.

The Audit Committee of the UAL Board of Directors has adopted a policy on pre-approval of services of the Company's independent registered public accounting firm. As a wholly-owned subsidiary of UAL, United's audit services are determined by UAL. The policy provides that the Audit Committee shall pre-approve all audit and non-audit services to be provided to UAL and its subsidiaries and affiliates by its independent auditors. The process by which this is carried out is as follows: For recurring services, the Audit Committee reviews and pre-approves the independent registered public accounting firm's annual audit services in conjunction with the annual appointment of the outside auditors. The reviewed materials include a description of the services along with related fees. The Audit Committee also reviews and pre-approves other classes of recurring services along with fee thresholds for pre-approved services. In the event that the additional services are required prior to the next scheduled Audit Committee meeting, pre-approvals of additional services follow the process described below. Any requests for audit, audit related, tax and other services not contemplated with the recurring services approval described above must be submitted to the Audit Committee for specific pre-approval and cannot commence until such approval has been granted. Normally, pre-approval is provided at regularly scheduled meetings. However, the authority to grant specific preapproval between meetings, as necessary, has been delegated to the Chair of the Audit Committee. The Chair must update the Audit Committee at the next regularly scheduled meeting of any services that were granted specific pre-approval. On a periodic basis, the Audit Committee reviews the status of services and fees incurred year-to-date and a list of newly pre-approved services since its last regularly scheduled meeting. The Audit Committee has considered whether the 2020 and 2019 non-audit services provided by Ernst & Young LLP, the Company's independent registered public accounting firm, are compatible with maintaining auditor independence. All of the services in 2020 and 2019 under the Audit Fees, Audit Related Fees, Tax Fees and All Other Fees categories below have been approved by the Audit Committee pursuant to paragraph (c)(7) of Rule 2-01 of Regulation S-X of the Exchange Act. The aggregate fees billed for professional services rendered by the Company's independent auditors in 2020 and 2019 are as follows (in thousands): Service 2020 2019 Audit Fees $ 6,000 $ 4,323 Audit Related Fees 302 403 Tax fees 170 174 Total Fees $ 6,472 $ 4,900 Note: UAL and United amounts are the same. Audit Fees. For 2020 and 2019, audit fees consist primarily of the audit and quarterly reviews of the consolidated financial statements and the audit of the effectiveness of internal control over financial reporting of United Airlines Holdings, Inc. and its wholly-owned subsidiaries. Audit fees also include the audit of the consolidated financial statements of United, attestation services required by statute or regulation, comfort letters, consents, assistance with and review of documents filed with the SEC, and accounting and financial reporting consultations and research work necessary to comply with generally accepted auditing standards. Audit Related Fees. For 2020, fees for audit-related services primarily consisted of audits and/or agreed upon audit procedures related to prior years' audits of subsidiaries of the Company. For 2019, fees for audit-related services primarily consisted of accounting consultations for proposed or future transactions and identifying and testing changes in the internal control environment prior to the implementation of the new revenue accounting system, which went into effect during the third quarter of 2019. Tax Fees.
