Just a few things (oh wait - lot of things) you got wrong there;
PR still operate YVR-LAS; while not all YVR-MNL continue to LAS, some still do for example today's flight.

US suspended the route in October, then canceled for good in Dec (

DL don't/haven't operated YVR-LAS at any time in the last 10 years. In fact DL themselves only have seasonal service into YVR, relying mostly on OO to operate YVR-SLC
My bad, I did mess up on a few of those. I didn't think Delta operated to LAS, either, until I saw this on the FIDS:
12:30 Delta Air Lines DL4655 Las Vegas (LAS) On Time E90
I also pointed out that WS (not WJ/Air Labrador who don't even operate on this coast) isn't the leader out of the YVR market, G4 are, flying out of BLI.
Thanks for the clarification on WJ/WS - I wouldn't want anyone confusing WestJet for Air Labrador, since the latter is so well known as a major airline in Canada.
While BLI may be close to YVR, its not the same market. If we're going to include surrounding YVR markets, you might as well include YXX and YYJ. Hell, expand the distance a bit and we can throw in YQQ, SEA, YLW, and YKA.
