The Financial Post reports in its Tuesday edition that United Airlines Holdings and Air Canada are looking to expand their existing joint venture to include more U.S.-Canada routes, as travel between the two countries has been hammered by geopolitical pressures. A Bloomberg dispatch to the Post says the two carriers want to add 10 routes including Montreal-Chicago, Montreal-Washington, Ottawa-New York, Toronto-San Francisco and Vancouver-San Francisco. United and Air Canada have had a joint venture since 2022, allowing them to work together on some U.S.-Canada routes by co-ordinating flight schedules, ticket prices and marketing. Air Canada shares on Monday closed at $21.28, down 71 cents on the Toronto Stock Exchange.
