Unfortunately, WestJet does not operate flights to or from Los Angeles International Airport (LAX) as of my knowledge cutoff date of 2021. WestJet mainly operates in Canada, the United States, Mexico, the Caribbean, and Europe, but their US destinations do not include Los Angeles. However, other airlines do operate at LAX, and the airport has nine terminals serving various airlines. If you have a specific question about LAX or any other airport, I would be happy to help you.
