Do I have to re-enter my Known Traveler ID with every reservation?
I am frustrated with AS on Pre-check. My ID is in my UA account and I never have to worry about it (I am long-time Global Entry). With AS, I never seem to succeed, even if I enter my ID when I make a reservation. It's getting so bad, I just go to the elite line now and it's quicker.
Any advice on making sure the number gets in and accounted for?
