United Airlines and Air Canada are to add new non-stop flights between Washington-Dulles and Vancouver and Calgary.
The airlines are to use their "enhanced trans-border joint business agreement" to "collaboratively optimise" schedules with over 80 trans-border code-share routes and more than 260 daily flights.
"Our coordinated schedules will provide business travellers with the convenience of hourly service and the additional comfort of a business cabin on all flights between Toronto and New York and Chicago, as well as Vancouver and San Francisco," said Mark Galardo, senior vice president network planning and revenue management at Air Canada.
"With schedules designed to give customers more flexibility with timing and more convenient connection options, as well as the ability to enjoy the benefits of both airlines' loyalty programs, our agreement with Air Canada makes United the premier U.S. airline for travel to Canada," said Patrick Quayle, United's senior vice president of global network planning and alliances.
