I am sorry to barge in with a question but I am intrigued. I have been trying (and trying and trying) to book a simple one way flight from YEG to VYR in J. Five times it got as far as loading the seat plan and said there was an error. So I tried another bowser (Chrome) - ditto. I then took my pad and tried again - same again. Exasperated since the fare had gone up on the flight that I wanted, I mean big time - £186 to £432! I tried this time on the Ipad and did
not put in our Miles&Smiles numbers. Through it went.
I was on the UK site as they let you pay in £ and I can avoid exchange rates and charges and using a VPN as I am actually in Spain. The reason was given as Err 7 - but I went to manage the booking and whilst it insists that I be part of Aeroplan - it give me the option to change my husband's number - (I nearly said "husband" and realised that this was Air Canada and had to mind my Ps and Qs

). Anyhow back that came with the same Error so I have concluded that this was the problem all along
My question is - do any of you know better? Have you heard of this happening before? Is AC's IT as capricious and infuriating as that of BA? Mods: if this is too trite or trivial please dispatch into the cyber pit of closed threads with my apologies.
