Daytime eastbound transatlantic flights from Canada are rare, accounting for just 3% of passenger services to destinations in Europe, Africa, the Middle East, and other regions. Analysis using Cirium Diio data covering scheduled flights between August and December identified only three such routes: Halifax to London Heathrow, Montréal to Algiers, and Montréal to Casablanca.
These daytime flights typically cover shorter distances with fewer time zone changes and rely on strong point-to-point demand. Passengers may experience less jet lag but could spend more of their day traveling. Such services may also generate lower revenue than overnight flights because there is potentially less demand for lie-flat seats or beds. For North American operators, the aircraft often remains on the ground overnight at the destination airport, which can reduce overall productivity.
Air Canada operates a daytime flight from Halifax to London Heathrow. The airline ranks ninth among non-UK carriers in terms of Heathrow service frequency, with departures from six Canadian airports including Halifax. Air Canada has served this route for many years; initially flights stopped in St John's using Boeing 767-300ERs before becoming nonstop in September 2006. The switch to Boeing 737 MAX 8 aircraft occurred in April 2018 and continues today.
