Just tried to change FF numbers on our flight before checking in tonight.
VX put our Elevate # in and we want AS # mileage plan numbers. Went to VX app and was able to change husbands to AS #but , when I enter my AS #, it gives me an error message.
So, now I have to call.....might as well do it at check in window
Fully expect to find mix up again at airport tomorrow and have them change it again.
