Hi all, I have some flight credit from a flight I'd booked earlier with AA, that had my Alaska Airlines number attached. I want to book a flight and use it, but I want the new booking to have my Alaska number attached as well. However, when I get to the final payment page, I don't see the option to use flight credits to pay unless I use my AA number for the booking.

Do I have to call on the phone in order to accomplish this? Or is it simply not possible
