Not sure about other carriers, but out of Metro Vancouver area, you have
YVR AC: 1/day
YVR WS:2/day
Delta: 1/day
Philippine dropped this route last year and US Airways pulled out a year or two ago.
As for the WS numbers being higher than AC, remember that WS serve LAS from a lot of places that AC don't
So what you're saying is that if WS didn't service LAS from more cities, the numbers would be different? No kidding!
The yield on LAS,Hawaii,and Florida is always very low hence the reason AC puts their revenue assets in more profitable areas. BTW in terms of load factor AC is the leader in these markets.
AC isn't leader in this market because its a market WJ has dominated in recent years. Just like Hawaii. It's the vacation package part of the market that adds the gravy to the bottomline. If Air Canada can afford to move its assets to "more profitable areas" you'd think they'd actually make a profit.
