American Airlines and WestJet Airlines have launched a comprehensive codeshare agreement which allows American to place its ‘AA’ flight code on WestJet flights, and WestJet to place its ‘WS’ code on flights of American Airlines.

The two airlines say the codeshare will give customers of both airlines more choices and greater connectivity when travelling between the United States and Canada, as well as across American’s worldwide network.

According to American Airlines, placement of the AA code on WestJet flights will provide American’s customers seamless connecting service to nearly 20 Canadian cities not currently served by American or American Eagle. Initially, American will place its code on WestJet flights between Montreal and Winnipeg and flights linking Toronto with Edmonton.

By placing its WS code on American’s flights, WestJet will be offering its guests service to more than 30 new American U.S. destinations. WestJet will add these codeshare routes in phases, starting on American flights to Dallas/Fort Worth and Los Angeles via Toronto, with expanded service throughout the American Airlines network expected in the near future.

The codeshare agreement will make it easier and more convenient for customers to connect from WestJet to American’s global route network and from American to WestJet’s Canadian cities, the airlines say.

Members of the American Airlines AAdvantage program and WestJet’s Frequent Guest Program can now earn miles or rewards on the codeshare flights, providing customers another benefit of the enhanced relationship. The two airlines are exploring other ways to augment their cooperation in the future.

“Our codeshare with WestJet will give customers of both partners more departure choices, additional convenient flights, and a greater selection of route options throughout our North American network, while offering carefree connections to and from cities throughout Canada,” says Virasb Vahidi, American’s chief commercial officer. “American and WestJet intend to expand and deepen further the benefits to our joint customers of this cooperation in the near future.”

“We are delighted to launch this important strategic alliance to offer our guests more travel choices through American’s expansive list of U.S. and global destinations,” says Hugh Dunleavy, WestJet’s executive vice-president, strategy and planning. “With this important milestone in our history, we continue to deliver on our strategic plan to seek commercial agreements with valued partners in major geographical regions around the world.”
