Well after an hour and a half of trying to reserve (which i acomplished) I wanted to purchase, the Air Canada Tango Web Loonie fare from YVR - YYZ, here is what i recieved:
Due to the extreme number of customers accessing Interactive Services
at this time, Shop for Fares is not available.
Please try again later. We apologize for this inconvenience.
Well that is just great, thank you Air Canada!!!! They probably do this to piss people off so instead of buy 1 dollar fare's, you'll break down and buy a normal fare cause your too pissed off to keep trying.
