Travelling YUL-MIA in a few days and AA.com asks for lots of information (passport number, among others). I'm not too keen on giving this online and was wondering how mandatory this is (I honestly don't know how "sensitive" a passport number is...).
I'm guessing this is for online check-in? And if I opt for checking-in at the counter, then no need for that info over the net? On the other hand : I never checked-in online, but can I still do it without entering that info online?
