so now I've booked a flight ticket from YYZ to HKG. At first I entered my AP number when booking, but now I have changed it to my continental One Pass account.
After I entered my one pass account number, when I get to seat selection, I am allowed to book the preferred seats. They didn't ask me to provide payment information. For my understanding, a star alliance gold member like me, if I book Latitude class, then the preferred seats are free. However my ticket to HKG is just in tango plus class. I am wondering if they are going to ask me to pay when I check in at airport?
