With Orlando at 95.1% load factor, I could see WestJet looking into Fort Lauderdale.
Denver on United at 92.2% load factor is also extremely strong, and fares are high on that route. Seems like there's money to be made on serving an additional United hub like Chicago. Houston would also perform well I have no doubt.
Los Angeles is also really strong and despite being one of the higher capacity routes is still evidently jam packed.
Honolulu doing well. I don't know if revenue is as strong on Honolulu - tends to have less expensive fares.
Seattle on WestJet could move up to a 737.
There's room for additional US hub service - New York, Dallas, Chicago.
The numbers paint a picture of a pretty strong market in YEG overall.
