Air Canada United new routes link six cross-border cities

Two of North America's biggest airlines are tightening the map between the two countries. Air Canada and United Airlines announced on Friday that the Air Canada United new routes package will add six cross-border nonstops for summer 2027, the largest single-season expansion of their transborder partnership to date. Air Canada will launch three new nonstops from Toronto, Montreal and Edmonton into the United States, while United adds three of its own reaching Ottawa, Quebec City and St. John's. The carriers also submitted an application to Transport Canada to renew and expand the joint business agreement that underpins the growth.

Air Canada's share of the Air Canada United new routes plan centers on three American cities, the airline said in a news release. Toronto gains a nonstop to Louisville, Montreal gains a daily nonstop to Indianapolis, and Edmonton gains service to Newark, each timed for the summer travel season. Edmonton to San Francisco also gets a bigger airplane, moving up to the Airbus A220 for added seats. Toronto to Louisville begins April 28, while the Montreal to Indianapolis and Edmonton to Newark flights start June 1.

Louisville and Indianapolis score firsts

The Louisville leg is the headline. Louisville's airport will get its first scheduled international route on a major global carrier and its first daily international flight, according to the airport authority's announcement. The Toronto service runs on a 76-seat CRJ-900 with business and economy cabins, and it plugs Louisville into Air Canada's Toronto hub, which connects onward to more than 150 destinations. Airport executive director Dan Mann called the launch a milestone for the airport and the community, noting Toronto has been a top priority for years. The route was backed by $4 million in state incentives from this year's legislative session aimed at chasing new nonstop service, and the Louisville Hotel Partnership also supported the carrier's arrival.

Indianapolis travelers get a new door to Canada as well. Air Canada will fly nonstop between Indianapolis and Montreal once a day in both directions, the Indianapolis Airport Authority announced. The route makes Montreal the airport's 58th unique destination, a record for the airport. Executive director Mario Rodriguez said Hoosier travelers gain nonstop reach to an international business hub, with six international destinations now reachable without a connection from Indianapolis.

United's side of the map

United is filling in its own gaps north of the border. The carrier will fly nonstop from Denver to Ottawa and Quebec City, and will run seasonal service between Newark and St. John's, according to the announcement. It will also add seats on its Washington, D.C. to Quebec City and Denver to Winnipeg routes. United network chief Patrick Quayle said the joint schedule has grown every year since the transborder agreement was signed, and the new flights continue that investment in Canada. The Air Canada United new routes are coordinated so the two networks feed each other rather than overlap.

Behind the route map sits a bigger business deal. The two airlines signed their transborder joint business agreement in 2022, and they have now asked Transport Canada to approve a renewed and expanded version. Since the original deal, more than 4.3 million passengers have flown on the two carriers' joint network, Air Canada said. For travelers, the practical payoff of the Air Canada United new routes is simpler itineraries: new one-stop options between mid-size American cities and Canada, plus more nonstop choices that skip the usual connection hubs.

The additions extend a pattern of both airlines pushing beyond the biggest hubs into mid-size cities on both sides of the border. For Louisville and Indianapolis, the new flights mean a direct link to Canadian business centers and a shorter path to Europe and Asia through Toronto and Montreal. The Air Canada United new routes show how aggressively the two partners are competing for the next wave of transborder traffic, and more city pairs could follow if the summer schedule performs.

Travelers can follow the new services through each airline's booking channels. The announcement was reported by Dow Jones Newswires and covered in detail by local outlets in Louisville and Indianapolis: Morningstar/Dow Jones report and the Indianapolis Star's coverage of the Montreal route.
