Explanation of Responses:

1. Transactions exempt from Section 16(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act").

2. On September 29, 2026, the transactions contemplated by the Agreement and Plan of Merger, dated as of May 2, 2026, by and among Global Business Travel Group, Inc. (the Issuer) and the other parties thereto (the Merger Agreement), were consummated (the Merger). At the effective time of the Merger (the Effective Time), each share of Class A common stock, par value $0.0001 per share, of the Issuer (the Class A Common Stock) issued and outstanding immediately prior to the Effective Time, other than shares excluded under the Merger Agreement, was automatically cancelled, extinguished and converted into the right to receive $9.50 in cash. Accordingly, the 157,786,199 shares of Class A Common Stock held by American Express International, Inc. (Amex HoldCo.), an indirect, wholly owned subsidiary of the Reporting Person, were disposed of as described above. Following the Effective Time, the Reporting Person no longer beneficially owned any Class A Common Stock.

3. In connection with the Merger, at the Effective Time, Amex HoldCo. ceased to hold 5,637,394 C ordinary shares of GBT JerseyCo Limited (the "C Ordinary Shares"). Following the Effective Time, the Reporting Person no longer beneficially owned any C Ordinary Shares.

Remarks:

Prior to the Effective Time, the Reporting Person may have been deemed a director by deputization of the Issuer for purposes of Section 16 of the Exchange Act.
