I booked a flight on AS for next month and asked them to include my AAdvantage number on the booking so I am credited with miles. I opened the AS app this morning and noticed my flight was gone. Looked it up via confirmation code and it looks like they removed my AS Mileage plan number and in place put my AAdvantage number. Is there no way to have both on the booking so I can still use the app for my boarding pass?
