This is not a review of their frequent flyer program or a review by a frequent flyer:
Westjet is fine for what it is, an airline that goes to many places in Canada. Think of it as Canada's JetBlue, except that they use Boeing 737s. You get one bag checked free. All the staff at the airport were friendly and helpful.
The leather seats are fine.
The service is fine, the flight attendants are expedient and helpful. The In-flight sandwich for 6.50 CAD is worth it. Satellite TV also helps the time go by quicker. Depending on flight-length, there are also premium movies for purchase.
They also offer seasonal service from John Wayne Airport (SNA) to Calgary, which is very convenient if you happen to be an Orange County Resident.
