Now consider the following:

1. WestJet is a Canadian airline.
2. This would seem to be yet one more example of a foreign airline providing superior service relative to U.S. domestic airlines.
3. According to the U.S. Department of Transportation, U.S. law has long-banned foreign air carriers from serving solely domestic routes, thus:

Air France could not carry a Los Angeles-originating passenger on a one-way flight from LA to New York. However, it could carry the passenger from LA to New York if the passenger had a through Air France ticket to Paris and, following a stopover in New York, boarded another Air France flight to Paris.

Ergo, an outdated protectionist measure may be keeping you from the best flight ever.
