Best in Canada
I noticed that WestJet gets many compliments on this site but they are usually referenced in complaints about Air Canada so thought West Jet deserved its own review.
For my friends south of the American border of you should ever find yourself travelling to the great white north visit west-jet.com before making your reservation to see if they have a flight departing from near you.
West-Jet has several advantages:
(1) By policy they NEVER overbook flights
(2) Have the best on-time record of any airline operating in Canada
(3) They have given all their staff stock options and travelling them you can tell the employees are vested in the companys success. They are very helpful and courteous
(4) 80% of their flights have individual entertainment for passengers in the form of seatback LCD TVs, even for short haul flights.
With all this they are reported to be one of the most profitable airlines per passenger in North America despite operating with a business model that seems more expensive (ie no overbooking, stock for everybody).
Slight drawbacks for me as a business traveller is the lack of business class seating and not having a frequent flier program. But for peace of mind flying they are are without peer in my experience.
