Porter Airlines has reduced its U.S. operations by ending its Toronto to San Diego flights and canceling a planned Montréal to Las Vegas route. The airline started the San Diego service last December with four weekly flights using Embraer jets. However, due to a drop in passenger numbers, Porter will stop this service at the end of June, scaling back its presence in California. The planned Montréal to Las Vegas route, set to launch in January 2026 with three weekly flights, has also been canceled before it began. These decisions highlight Porter Airlines’ adjustment to the recent decline in cross-border travel between Canada and the United States.

The Toronto to San Diego route targeted winter travelers seeking West Coast destinations and operated on select days throughout the year. Porter had expanded aggressively in California, including adding flights to San Francisco and Los Angeles last summer. Despite these efforts, the airline will reduce capacity by over 32,000 seats by cutting the San Diego route. Air Canada remains the only airline flying this route, offering daily flights.

The cancelled Montréal to Las Vegas route would have been Porter’s longest, covering more than 2,200 miles. Air Canada continues to offer strong service on this route with multiple weekly flights. These route cancellations follow a steep 70 percent drop in U.S.-Canada travel bookings compared to last year. Political tensions and tariffs between the two countries have contributed to this decline. While Air Canada and WestJet have already reduced their U.S. flights, Porter initially maintained its routes but has now adjusted its network to focus on higher-demand markets like New York.

Porter Airlines plans to strengthen its Canadian domestic network to respond to shifting travel patterns. The airline recently launched new routes from Hamilton, reflecting a strategic shift to focus more on the domestic market. As demand for cross-border flights weakens, Porter aims to optimize its fleet and routes toward more profitable destinations.
