WestJet Airlines has taken off in Canada -- and beyond -- by following the Southwest Airlines business model. The low-fare carrier serves more than 65 destinations, mainly in Canada but also in the US, the Caribbean, and Mexico. It operates a fleet of about 80 Boeing 737s that feature live seatback satellite TV (from BCE's Bell ExpressVu). The carrier is working to expand its fleet to about 135 aircraft. Most of WestJet's destinations outside Canada are vacation spots, and subsidiary WestJet Vacations allows customers to book hotel accommodations along with their airline tickets. WestJet was founded in 1996.
