Can say for other airlines, but for AC, even though there's no announcement of game-changing new destinations, seems like they are still adding quite a bit of capacity at YVR.
In term of frequency, my preliminary number shows this year YVR have the biggest increase from AC out of the 4 hubs with net total of about 7 daily additional flights. Can't say about the capacity though, as I'll have to enter all the flights for next summer into my spreadsheet first
Something I'd noticed earlier... the second daily for YZF will start on Aug 1 this year. In comparison, August last year had no service to YZF, and the second daily was started only in November.
Also, every time I checked AM schedule, more flights had been added. Now the third flight runs all the way to the end of April, running on most Sat and Sun for the month.
As for Flair, so far this year's operation at YVR seems to be smaller compared to last year:
- daily YEG that continues to YYZ (compared to 2-3x daily to YEG last summer)
- 5x weekly YYC (6x last summer)
- 5x weekly YWG (2x last summer)
No more direct service to YLW.
