Am currently attempting to book ORD-YVR return in February. The flights that I want keep coming up as available but then, when I click on the "Purchase Tickets and Choose Seats" option, it gives me an error message. Hence, I phone technical support - they advise me that this particular message means that one of the flights I want is not available at the booking class I want and that I should choose another booking class.

How ridiculous is this? The website shows the both the outbound ORD-YVR on UA and the return on the redeye through YYZ are available. There's no indication as to which of the flights I have selected is not available since I would much rather tweak my travel itinerary rather than pay a five-fold increase in the fare at a different booking class. However, the only way I know whether my "revised" itinerary is available is if I start playing with various permutations and combinations and doing the booking each time and see if I make it past the final screen.

Has anybody else encountered similar frustrations with the AC website?

Thanks,

I have been trying to book a reward ticket for 2 days on the aeroplan site and keep getting an error message too. Pissing me off.......

I experienced the exact same problem over two years ago with the Zip website. Sounds like they are using the same booking engine and the same no-help desk.

I eventually bought my ticket on Westjet.
