The passport number should stay the same when you renew so just give them the old one
Give any #. That should hold the ticket. I doubt they'll ever compare the 2 numbers down the line. If they do, you'll have a valid passport in hand for both yourself and your baby.
Passport is being renewed. Booking site I used booked the ticket but then emailed me that without passport the ticket will be cancelled.Nothing to do right?
Wrong
Still would like to know which site requires a passport?
Air Serbia for one
Singapore Award requires as well, wondering which OP used that they emailed him that they will cancel without the PP number
Transaero, did.
