Air Canada and United Airlines have announced that their new enhanced transborder agreement will bring new routes between Canada and the U.S. for summer 2023 – including a new United-operated flight between Washington-Dulles and Calgary and a new Air Canada-operated flight between Washington-Dulles and Vancouver.
The carriers have collaboratively optimized their schedules and added more flights to provide customers greater connectivity and more flexible flight times, with over 80 transborder codeshare routes and more than 260 daily flights.
"This summer, customers will have even greater choice and convenience with our joint summer schedule made possible by our airlines' new enhanced transborder agreement," said Mark Galardo, Senior Vice President Network Planning and Revenue Management at Air Canada. "Our coordinated schedules will provide business travelers 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."
Patrick Quayle, Senior Vice President of Global Network Planning and Alliances at United Airlines added, "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."
New Non-stop Flights Between Vancouver, Calgary and Washington
New, non-stop service between Vancouver and Washington-Dulles will begin 1JUN and will be operated with an Air Canada Boeing 737 Max 8.
United will also introduce a new, non-stop flight between Calgary and Washington-Dulles on 2JUN on an Airbus 319.
Air Canada and United will codeshare on these flights, allowing Aeroplan or MileagePlus members to accumulate and redeem miles. Eligible customers and loyalty plan members will also be able to enjoy benefits including priority check-in, lounge access, priority boarding and other benefits where available.
