Air Canada and British Airways are the flag carriers of Canada and the United Kingdom. Both are full-service airlines, members of rival alliances (Star Alliance and oneworld), and both fly between London Heathrow and Canada. Travellers compare them mainly for transatlantic trips, where the choice affects the hub, the cabin and the loyalty scheme.
Quick verdict
For flights within Canada or onward from Canada to the US and beyond, Air Canada is the natural choice, because its network is built around Canadian cities. British Airways suits travellers starting in the UK or Europe, or connecting through Heathrow to its wider network. On the London to Canada routes the two are close, so fare, schedule, loyalty programme and baggage rules should decide it. On Air Canada's North American routes, check the Economy Basic carry-on rules before booking.
