I am wondering if anyone has experience with using both a paper voucher and also an AA Gift Cards? I ask because the process of ticketing requires a phone call to AA to inform them of redeeming a paper voucher. I am hoping at the time of talking to the agent about the paper voucher, you can use an AA Gift Card to cover any fare difference after the paper voucher is used. I realize that you can ticket at an AAirport using a paper voucher, but I plan on mailing it in instead. Thanks!
