TORONTO — Porter Airlines and Alaska Airlines have signed an interline agreement, allowing customers of both airlines to book combined Porter-Alaska itineraries.

The carriers say their partnership optimizes Porter’s presence across Eastern Canada and Alaska’s U.S. West Coast links, for more coast to coast connectivity.

Starting in January 2024, Alaska’s Mileage Plan members can start earning points on Porter flights booked via Alaska Airlines. Later in 2024 both VIPorter and Mileage Plan members will earn miles in their respective loyalty programs no matter where they book their flights.

Next year will also bring access to mileage redemptions with enhanced availability for both VIPorter and Mileage Plan members on each other’s airline.

Porter and Alaska will continue to strengthen their partnership in 2024, says Porter’s EVP and CCO, Kevin Jackson. “This partnership with Alaska Airlines is a significant win for passengers looking for more choice and better service when flying within Canada and the United States. Alaska and Porter emphasize passenger service excellence on each and every flight. We’re excited about what this means for passengers across North America,” he said.

Jackson pointed to Porter’s new flights connecting Toronto Pearson and California starting in January, noting that Porter passengers will be able to fly directly into major Alaska Airlines hubs in L.A. and San Francisco. Through these hubs and existing Porter destinations like Boston and New York, passengers can initially access 18 western U.S. markets including Portland, San Diego, Seattle and Phoenix, all available via an Alaska Airlines connection. Connections via shared Canadian airports are expected to come online in early 2024.

“Porter Airlines opens new opportunities for our guests to travel to Canada in style,” said Brett Catlin, VP Loyalty, Alliances and Sales at Alaska Airlines. “We’re thrilled to partner with a vibrant and growing airline, and eager for our flyers to enjoy the refined experience that Porter offers, including top-notch inflight service and terrific onboard amenities.”

The Porter Airlines – Alaska Airlines interline agreement comes on the heels of news about Porter’s strategic alliance with Air Transat. On Nov. 28 Air Transat and Porter Airlines announced an expansion of their existing codeshare agreement, with the creation of a joint venture. Porter is in the midst of a multi-year, massive expansion, first announced in 2021, with some 80 new aircraft, new gateways and routes.

Earlier this month Alaska Airlines announced its intentions to acquire Hawaiian Airlines. The combined company would maintain both airlines’ brands. The deal is subject to regulatory approval.
