Porter Airlines expands US network with new routes under American Airlines partnership

For American Airlines, this agreement strengthens its network in Canada. Its main competitors, Delta Air Lines and United Airlines, have close partnerships with WestJet and Air Canada respectively.

Porter will not face direct competition on the MIA-YOW and PHX-YOW routes. However, it will compete with Air Canada, Flair Airlines, and WestJet on the PHX-YVR route.

In addition to these new services, Porter plans to increase frequencies on two existing U.S. routes: Fort Lauderdale-Hollywood International Airport (FLL) to John C. Munro Hamilton International Airport (YHM) in Ontario and Toronto Pearson Airport (YYZ).

"Porter's new U.S. routes will run as follows:

MIA-YOW: Three weekly flights on Mondays, Fridays and Saturdays from Jan. 24, 2026

PHX-YOW: Three weekly flights on Tuesdays, Thursdays and Saturdays from Feb. 7, 2026

PHX-YVR: Daily flights from Feb. 2, 2026"

The partnership comes after an earlier plan by American Airlines to work with Connect Airways for service at Billy Bishop Toronto City Airport (YTZ), which did not materialize.

This move marks another step in Porter's ongoing growth into the U.S. market through strategic alliances.
