Building on a Long-Standing Partnership
In July 2022, Air Canada and United announced a joint business agreement for the Canada-U.S. transborder market, building on their long-standing partnership that will give more flight options and better flight schedules to customers traveling between the two countries (coordination subject to regulatory conditions)
Air Canada and United are also founding members of Star Alliance and a transatlantic joint business agreement with the Lufthansa Group.
In 2019, the U.S.-Canada transborder market was the second-largest international passenger air transportation market in the world and the largest international market for both Canada and the U.S., as measured by seats.
