I don't yet have my plastic EXP card, only the image of the card in the AAdvantage app. I'm traveling with my family on Alaska and will have 2-3 bags to check and would obviously like to take advantage of the free baggage allowance, as well as priority boarding. Since it would be very easy to mock up an image of a fake card, I'm guessing AS will only accept the real McCoy.

Does anyone have any direct experience in this matter?
