Porter Airlines and American Airlines are planning a new codeshare partnership aimed at enhancing cross-border connectivity between Canada and the United States, reports Simple Flying.
The two carriers submitted a joint application to the U.S. Department of Transportation (DOT) on July 25, 2025, seeking approval for reciprocal blanket codeshare services.
According to reports, if approved, the deal would position American Airlines to better compete with established transborder partnerships, such as Air Canada's partnership with United Airlines and WestJet's partnership with Delta Air Lines.
Neither airline has publicly announced the proposed agreement.
The partnership would offer benefits for both carriers. Porter Airlines stands to expand its footprint in the U.S. by connecting its Canadian hubs—Toronto Pearson (YYZ), Ottawa (YOW), Halifax (YHZ), and Montreal (YUL)—to American’s vast domestic network.
Porter would operate codeshare flights on routes linking these Canadian cities with U.S. destinations already served in its network, with the exception of Boston (BOS), Newark (EWR), Washington Dulles (IAD), and Chicago Midway (MDW).
Currently, Porter serves 16 destinations in the U.S. Twelve are expected to be included in the codeshare agreement:
- Las Vegas (LAS)
- Orlando (MCO)
- San Francisco (SFO)
- Los Angeles (LAX)
- Palm Springs (PSP)
- Tampa (TPA)
- Fort Lauderdale (FLL)
- Miami (MIA)
- Phoenix (PHX)
- Fort Myers (RSW)
- San Diego (SAN)
- West Palm Beach (PBI)
American Airlines would benefit from increased access to Eastern Canadian markets and stronger feeder traffic from Porter’s domestic routes.
The agreement would allow American to place its code on Porter flights to and from Canadian cities such as Toronto, Montreal, Halifax, and Quebec City (YQB), while also extending connections through its U.S. hubs—including Dallas/Fort Worth (DFW), Miami (MIA), and others—to points across Latin America, Central America, the Caribbean, and South America.
