I just used part of my “flight credit” from a canceled flight due to COVID-19 yesterday for a trip in October 2021.
I received the remainder of my flight credit in an e-voucher within 24 hours. The voucher has a 12 month expiration date. The agent said that unlike the flight credit that requires travel to be completed by the expiration date, you just need to make a flight reservation prior to expiration of the voucher. She added that since AA’s flight schedules are available 11 months out, you effectively have 1 year plus 11 months to complete travel.
I have to say that AA website was not tremendously helpful and I kept getting different answers through the refunds and flight credit phone lines. However, I finally got a knowledgeable agent last night who was able to book my flight and clearly explain what would happen to the remaining flight credit.
