Anyone else have trouble using discount codes tonight? Had a targeted 20% off promotion expiring at midnight on December 16th. Went to book flights this evening from Halifax to Miami for February, and was getting the error message:

"There appears to be an issue with the flights you selected; please try again, or try choosing different flights. If the problem persists, please contact Air Canada Reservations for assistance. (77177)"

The error only occurred when trying to use the code. At this point its already 10pm, so I called reservations, and they picked up at 11 (wow only an hour). They are able to get me the price I want with the 20% off code but say they'll need to get someone over from ticketing to price it manually. Get put on hold for an hour and a half. They come back on at 12:30am saying that the discount code has now expired, and I'm SOL. They tell me to book the tickets and write into customer relations and hope I get some money refunded. What a great use of 2.5 hours, and $300 that I will probably never get back...
