Booking reference.

Still, f the Aeroplan number is in the file, and the system does not recognize it, it might not validate. Even if it does, getting the miles/AQDs might be a hassle.

I seem unable to buy on the old/current site if using my Aeroplan number. somehow there is some confusion with title, and the number does not validate. If I buy as a guest and with no Aeroplan number, I can enter it when looking at my reservation.

I suspect their system does nome funny thing with some tracking sites that I am blocking in my hosts file.
