Next Thursday I'm on the YYZ - YYC 651 at 5:45. I've thought about it and think I would like to leave earlier but I'm on a super cheap fare I bought in a sale a few weeks ago.

I understand the change fee that Westjet applies now, but don't want to waste the day at the airport. Is there some nice person here who could check and tell me which flight(s) are least loaded for that day so I can have a stab at making an earlier flight?

Thanks.
