Where the WS code comes from
WS comes from WestJet, the Calgary-based carrier founded in 1996 on the Southwest low-cost model. The W and S are simply the name's two halves. WestJet has stayed outside the global alliances, and its home base Calgary International (YYC) is the code's natural companion page.
