American Airlines and Porter Seek Codeshare Approval to Link U.S. and Canada

American Airlines and Porter Airlines submitted a joint filing to the U.S. Department of Transportation (DOT) on July 25, seeking approval for a reciprocal codeshare agreement.

The agreement would allow each carrier to sell seats on the other’s flights using its own airline code, streamlining passenger experience and expanding market access. American would place its “AA” code on Porter-operated services, while Porter would use its “PD” code on American flights.

For American Airlines, the partnership fills a long-standing gap in its Canadian network. While competitors like United and Delta already benefit from partnerships with Air Canada and WestJet respectively, American lacked a strong regional Canadian partner.

Porter, now operating Embraer E195-E2 jets, has evolved from a regional carrier into a transcontinental operator, offering flights from eastern Canada to U.S. sun destinations and into the Caribbean and Mexico.

With this codeshare, Porter can now provide one-stop connections into American’s massive domestic and international network via key U.S. hubs like Dallas/Fort Worth, Charlotte, and Miami.

Although subject to regulatory approval, the request aligns with existing U.S.–Canada Open Skies agreements and follows a standard framework used in other transborder airline partnerships. The codeshare could lead to future loyalty program integration and joint check-in and baggage handling.

While no public announcements have been made by either airline, the agreement could come into effect by late 2025, pending DOT approval.
