At LGA, I usually check-in. If I am not checking-in, I will flash the card. Same with JFK.
PHX -- Again, I am usually checking in and I dont present the card. Othertimes, I flash it.
TPA (Tampa) -- I dont think we have an AC. We used to be able to use US Airways.
Miami -- Flash it (I am usually connecting).
ORD -- Flash it.
BOS -- same thing
I never show my EXP card -- they are lucky I carry it with me. But now with telephone and kiosk check-in, I will have to!
