PRICING SUPPLEMENT

February 3, 2026

United Airlines Holdings, Inc.

$1,000,000,000 4.875% Senior Notes due 2029

Pricing Supplement dated February 3, 2026 to the Preliminary Prospectus Supplement dated February 3, 2026 of United Airlines Holdings, Inc. ("UAL") (the "Preliminary Prospectus Supplement").

This Pricing Supplement is qualified in its entirety by reference to the Preliminary Prospectus Supplement. The information in this Pricing Supplement supplements the Preliminary Prospectus Supplement and supersedes the information in the Preliminary Prospectus Supplement to the extent inconsistent with the information in the Preliminary Prospectus Supplement.

Unless otherwise indicated, terms used but not defined herein have the meanings assigned to such terms in the Preliminary Prospectus Supplement.

*Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

†Note: It is expected that delivery of the Notes will be made against payment therefor on or about February 6, 2026, which will be the third business day following the date hereof (this settlement cycle being referred to as T+3). Under Rule 15c6-1 of the SEC under the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to the trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to the initial T+3 settlement may be required, by virtue of the fact that the Notes initially will settle on a delayed basis, to specify an alternate settlement cycle at the time of any trade to prevent a failed settlement, and such purchasers should consult their own advisor.
