Air Canada and United Airlines announced a joint business agreement for the Canada-U.S. transborder market, building on their long-standing alliance, that will give more flight options and better flight schedules to customers traveling between the two countries. Customers will be able to connect to 38 codeshare destinations in the U.S. and eight of the most popular cities in Canada — all while enjoying the benefits of the carriers' MileagePlus® and Aeroplan loyalty programs. The agreement will also strengthen and grow both carriers' networks and help accelerate their COVID-19 recovery.

Customers who search for flights between the U.S. and Canada on United's or Air Canada's websites and apps will find more flight options scheduled at more convenient times. Codeshare between the two carriers will also be expanded and members of both the MileagePlus and Aeroplan programs will have more accrual and redemption options.

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.

Air Canada and United already cooperate in the transborder market, according to the terms of their existing U.S. antitrust immunity. Under the joint business agreement, subject to compliance with U.S. and Canadian regulatory and antitrust requirements, the two airlines will now be able to:

• Coordinate their networks and schedules, enabling the carriers to offer customers more choice, including more flights throughout the day and more access to each airline's seat inventory
• Enhance codeshare on transborder flights, excluding certain U.S. leisure markets and territories. The carriers anticipate customers will be able to connect to 46 transborder codeshare destinations with more than 400 daily frequencies in 2022 – with opportunities to add more codeshare destinations for domestic routes within Canada and the U.S.
• Sell seats on each other's transborder flights and share revenue on flights between hub markets (where regulatory authorities and antitrust requirements allow), allowing the carriers to grow their overall capacities
• Align customer policies for greater consistency and enable the seamless provision of onboard products, establish airport co-locations where available and provide extra value to each carriers' frequent flyer programs
• Allow the two carriers to work closer together to advance their sustainability objectives

The implementation of an expanded partnership builds on the existing close cooperation of the two carriers and previously acquired regulatory approvals. United and Air Canada are also founding members of Star Alliance and a transatlantic joint business agreement with the Lufthansa Group.
