Air Canada is Canada's flag carrier and largest airline, founded in 1937 and headquartered in Montreal, operating 335 aircraft to 208 destinations via hubs in Montréal, Toronto, and Vancouver, while being a founding member of the Star Alliance. Its predecessor, Trans-Canada Air Lines (TCA), launched its first passenger flight from Vancouver to Seattle in 1937 and became the first airline in the world to use a computer reservation system (ReserVec) in 1953. Renamed Air Canada in 1965—a change championed by Jean Chrétien and first flown by Queen Elizabeth II—the airline was privatized in 1988, acquired rival Canadian Airlines in 2000, and filed for bankruptcy protection in 2003 before emerging from restructuring the following year. Today, it operates a mixed Airbus and Boeing fleet with divisions like Air Canada Cargo, Express, Jetz, and Rouge, running over 1,600 daily flights and carrying 45.3 million passengers in 2025.
