There are effectively two major airlines in Canada: Air Canada and WestJet. Air Canada has gone from being a government subsidized airline to a private company, gobbling up other private airlines. WestJet is the latest of airline companies who provide competition with Air Canada for across the country, as well as some international flights.
We recently flew to Vancouver from Ottawa. This was the first time we have flown on WestJet and based on our experience, we would definitely fly them again. On the way out, we had a brief stop-over in Calgary. The flight attendants on both flights were friendly, attentive and in the case of Michael, hilarious. Michael made a "show" of the emergency announcements and both times, got the attention of most passengers, to the point of making the other flight attendant laugh during her announcements.
Only downside was on the flight back where the pilots did not welcome the passengers on-board (a small thing) and neglected to mention a possible delay (about 20 minutes - kind of major).
WestJet doesn't charge extra for bags which is a plus (although we usually go carry-on anyways) but you do have to pay for snacks, a common practice these days. As far as equipment goes, WestJet flies 737s, all equipped with TVs in the back of each seat, showing Bell channels and offering some pay per view. Honestly, it's not worth getting pay-per-view since you may be interrupted with announcements, making it impossible to really get a full watch of a show.
