I just booked tix today for may 2025 and after I got my email confirmation went into the website to add my loyalty number and am having the same issue. I go to edit my information under “manage booking” and when I put my AA number in, it says it’s not the right format. When I try to put in Alaska mileage plan number it says “the number is not correct”

also the booking code on my confirm is only 5 digits, so other OneWorld airlines don’t accept the booking code.
