Porter & American Airlines pursue codeshare partnership

American Airlines and Porter Airlines jointly filed a request on July 25 with the U.S. Department of Transportation (DOT) seeking approval for a reciprocal codeshare agreement.

The proposed partnership would allow both carriers to sell seats on each other’s flights under their own airline codes, enhancing convenience for travellers and broadening each airline’s market reach.

Under the agreement, American would add its “AA” designator to Porter-operated flights, while Porter would place its “PD” code on American’s services.

For American, the deal addresses a long-standing gap in its Canadian service. Unlike United and Delta—which have established partnerships with Air Canada and WestJet—American has lacked a significant regional Canadian partner. In this regard, partnering with Porter would be a logical move, points out One Mile At A Time. 

Porter, meanwhile, has expanded beyond its regional roots with the addition of Embraer E195-E2 aircraft, now flying transcontinental routes and serving sun destinations in the U.S., Caribbean, and Mexico.

Through the codeshare, Porter could gains access to one-stop connectivity into American’s domestic and global network via major U.S. hubs such as Dallas/Fort Worth, Charlotte, and Miami.

The filing aligns with the U.S.–Canada Open Skies agreement and mirrors similar cross-border airline partnerships. Over time, the agreement could pave the way for deeper cooperation, including shared loyalty benefits and integrated check-in and baggage services.

Although neither airline has publicly commented on the move, the partnership could launch by late 2025, pending regulatory approval.
