A slight change to OP's situation
Related to OP's post, but slightly different. What if I have a voucher from a canceled flight under the COVID policy, and I use that voucher to book a new ticket. If AA cancels the new flight (that I paid for with the voucher) would I be able to get a refund back to my credit card since it is a "canceled" flight? I'm guessing there's something that says that the airlines just have to refund back to the original purchase method versus saying the airline must "give a cash refund."
