What WestJet won't add is routes to Europe or Asia, because long intercontinental flights aren't possible on 737 planes, said Richard Bartrem, a spokesman for WestJet.
Because it's nearly impossible for a U.S. carrier to merge with a foreign airline, a code-share marketing arrangement is an easier and cheaper way for an airline to gain access to international markets, said Bob Harrell, a New York-based airline analyst.
"You get some of the benefits of running a single operation but none of the complications," said Harrell, president of Harrell Associates, a travel industry consulting group. "WestJet is a Southwest clone basically. There's a lot of synergy between the philosophical approaches of both businesses."
