Porter is the latest Canadian airline to scale back service to the U.S., joining a growing list of high-profile route cuts in recent months. The carrier will halt service on one of its newest routes.
As first flagged by Aeroroutes, the airline will not resume flights between Toronto and San Diego, a route that began in December. With this service cut, Porter will completely exit the San Diego market.
An airline spokesperson confirmed the route cut to AirlineGeeks, adding that Toronto-to-San Diego flights will end on June 25.
“We never want to leave any market. However, we are prioritizing operational reliability over the summer period, which requires additional spare aircraft capacity,” the spokesperson added in an email.
At just over 2,000 miles, the route is among Porter’s longest. The carrier also serves San Francisco and Los Angeles in California.

“This was a logical decision as San Diego is a newer addition to our network, having launched last December, and unfortunately hasn’t met our performance expectations,” the spokesperson continued. “The market and passenger preferences will continue guiding us as we make network decisions.”
Demand Lull
Other Canadian airlines have made transborder route cuts in recent months. Last month, WestJet slashed its Vancouver, British Columbia, to Austin, Texas, route before it even launched.
A March report from OAG said transborder bookings have dropped by 70%.
