Cancellations/Ticket Changes/Reissuance:
If the Primary ticket or the Companion ticket is cancelled, both tickets will be cancelled. If a wholly unused Primary ticket and Companion ticket are cancelled on/after December 7, 2023, the Companion Certificate redeemed will be automatically reissued after the cancellation is processed and will retain its original expiration date. Subject to the fare rules of the Primary ticket, the value of the Primary ticket, less any fare difference, may be applied to future travel.
