What if I used a companion fare? If the expiration date for your companion fare discount has passed, it will be forfeited. If your companion fare discount would have still been valid for ticketing on the date you canceled, please contact Reservations and we will issue a new certificate.
Mine expired in October and the phone rep said the only way to save the companion part was to cancel the ticket but leave it alone. I'll need to give the original ticket numbers when rebooking. Hope I can find something quickly to make sure it works as described.
