United Airlines and Air Canada are pushing to expand their transborder joint venture with ten additional US-Canada routes, even as geopolitical tensions have cut into travel demand between the two countries.
The proposed additions include Montreal-Chicago, Montreal-Washington, Ottawa-New York, Toronto-San Francisco, and Vancouver-San Francisco, according to a Transport Canada public consultation. The consultation closes November 15, 2026.
The expansion bid comes as cross-border traffic has taken a hit from ongoing geopolitical friction between the US and Canada. Joint venture growth in this environment signals both carriers see the route network as a long-term structural play rather than a near-term demand story.
For crew based in Chicago, Washington, New York, and the Bay Area, additional transborder flying under a joint venture framework typically means more codeshare operations and coordinated scheduling between the two carriers — relevant context for anyone holding lines or picking up open time on affected equipment.
