I'm usually logged into my account when I make the reservations - my husband had been complaining that I always get TSA Precheck and he does not - even though it's supposed to be random - so this time I booked from his account so he was "first", and it showed up under his account and not mine, that's why I noticed it - I always was adding the trips to his account. We'll see what happens with the precheck thing when we check in.
If I never add them to the other person's list, any problems with that?
