Porter Airlines and American Airlines: New Codeshare Partnership


To plan the flight today, read our American Airlines guide to Canadian departures, cabins, baggage, lounges, and points, checked on October 28, 2026. It explains AAdvantage and Avios booking routes; a codeshare does not guarantee points bookings on every marketed flight.
American Airlines and Porter Airlines have just announced a new codeshare partnership to offer their customers more travel opportunities between the United States and Canada. This is effective as of today.
For travellers, this codeshare offers several advantages:
In addition, there will eventually be the possibility to earn and redeem points from your preferred loyalty program, whether it’s VIPorter or American Airlines AAdvantage. This means your VIPorter points earned from Porter flights and purchases on the BMO VIPorter World Elite Mastercard can now be used for travel on American Airlines.
Porter will add its flight code (PD) to several American Airlines routes. This partnership is centred around American Airlines’ main hubs, including Charlotte (CLT), Chicago O’Hare (ORD), Dallas Fort Worth (DFW), and Philadelphia (PHL).
Coming soon:
You can already see these codeshare flights and book them directly on the Porter website for flights operated by American Airlines.

Conversely, American Airlines will eventually have access to many of Porter’s destinations in the Caribbean, Mexico, and Costa Rica.
As of today, American Airlines’ codeshare on Porter flights includes routes from Toronto (YYZ) to:
In the coming weeks, there will also be Calgary (YYC), Charlottetown (YYG), Kelowna (YKA), St. John’s (YYT), Saskatoon (YXE), and Vancouver (YVR).
Since September 1, 2026, you can leave from downtown Toronto and join American Airlines’ network in Chicago. Porter flies from Billy Bishop (YTZ) to O’Hare (ORD) twice a day, replacing its Midway service, according to its October 26, 2026 news release.
You also clear U.S. customs before you leave, thanks to the preclearance facility that opened at Billy Bishop in March 2026. You land at O’Hare as a domestic passenger, which makes it easier to connect to Denver, Houston, Minneapolis, Orange County, San Diego or Seattle, routes Porter lists with American Airlines.
This partnership between American Airlines and Porter Airlines offers more flexibility, better connections, and benefits for members of both airlines’ loyalty programs.
Perhaps we will soon see Porter join the oneworld alliance, which already includes American Airlines and Alaska Airlines?
