United Airlines is adding five new nonstop routes across North America, three of them to Canada, as part of a renewed and expanded transborder joint business agreement with Air Canada. The Canadian flights are planned for summer 2027; the two U.S. domestic routes are set for March 2027. Full schedules, aircraft and fares have not been released.

What are the new United routes?

United's Canadian additions connect three of its hubs to cities it has served before or never served at all:

  • Denver to Ottawa: Restores a link United flew until 2010; Denver becomes United's fourth destination from Canada's capital, according to the Ottawa International Airport Authority.
  • Denver to Quebec City: A brand-new route for the carrier.
  • Newark to St. John's: Seasonal service that brings United back to Newfoundland and Labrador, which it last served in 2016.

The two domestic legs, to Joplin and Lancaster, are temporary March 2027 flights. According to Simple Flying, they appear to be workarounds for construction limits at Chicago O'Hare, with Washington Dulles to Lancaster offered as an alternative while O'Hare operations are restricted. United is expected to use Bombardier CRJ-200 jets on those domestic itineraries.

How does the Air Canada deal affect travelers?

Air Canada is adding three U.S.-bound routes of its own for the 2027 season: Toronto to Louisville, Montreal to Indianapolis, and Edmonton to Newark. The two carriers describe the package as complementary. United's network chief, Patrick Quayle, said Canada is an important part of the airline's international network, and Air Canada executive Mark Galardo said the partnership has delivered results for customers and communities. The expanded joint agreement still needs approval from Canadian regulators.

What else is changing?

Beyond the new routes, United plans more Washington Dulles to Quebec City flights and a 65% increase in daily seats between Denver and Winnipeg. Air Canada will also upsize its existing Edmonton to San Francisco service to the Airbus A220.
