Plus seats? lol I highly doubt it! WestJet is the epitome of hypocrisy. WestJet is a LCC with Economy only seating. Crappy connections too. (once tried to fnd a flight from PHX-YLW, less than 3 hours direct, WestJet was happy to get me home in 2+ days) Completely "a la carte", ridiculous pricing, liars, exactly what they loathed when the started using the Southwest model when they took to the air on February 29th, 1996.
I can imagine Delta Elites will appreciate flying across Canada or to/from the United States in cramped economy. At least they will get Sky Miles while they enjoy their non-complimentary drink and snacks. Flying to Europe should be a blast on a 737 or if you are really lucky maybe you can get onto one of their 25 year-old 767's plagued with mechanical issues and you are so lucky to be stranded for days while they source the parts. You will still have to pay for your meal too, even in Plus, but Plus does have the added benefit of being able to order your meal (still a cost) before departure.
Can't imagine a LCC starting an ULCC. (Swoop) How could they possibly make it any worse? At the same time they are buying 10 Boeing 787's to reach into the South American & Asian markets. Can't wait to see that offerng.
