I'm booked Z class YVR-YWG rt non-stop this november, and two weeks ago they pushed forward my return flight by 35 min. Ok whatever.

Today I learned that they pushed forward my outbound flight by 7 hours from 7 am to 2 pm (there are no more direct am flights). My original flight was supposed to arrive in YWG at 1 pm which was good timing for my 5 pm meeting. Now the flight has to go through YYC, YEG, or YQR, and the earliest arrival time is 5:30 pm, or take the 6 am flight via YQR arriving at 12 pm.

Now, 6 am is too early for me. I don't live near the airport. I can't go mid-previous-day because I have other things I have to do. I was thinking of getting them to route me red eye via YYZ, and connect to YWG that way. Would they (or do they have to) let me do this since they changed their schedule on me? Is there some way I can convince them to do it? Thanks.
