You should go to the airline directly to see if they have space.Even if the ticket said valid ac only, 99.9% of the times United will take the ticket. I never turn a AC ticket away, cheeks in the seats is the way I look at it, your happy, were happy.Once again always go to the gate, or before you checkin with Air Canada, go over to the United checkin which is close by and see if they can pop you on.Even if I can't view your AC reservation in our computer system, who cares? I just make a new reservation for the United flight, it only takes about 30 seconds to make a reservation, pop in your aeroplan number and check you in. Some AC agents want you to think they are actually cracking a genetic code behind the computer when they are making a reservation or changing something. Its all just pop up windows,believe me its not difficult.
