Flights from Montreal to London
Montreal–London is one of the busiest transatlantic corridors out of eastern Canada, covering roughly 5,200 kilometres with a typical block time of six and a half hours eastbound and closer to seven and a half hours on the return against prevailing headwinds. Air Canada operates the route most frequently, often deploying Boeing 787 Dreamliners or Airbus A330s, while American Airlines serves it as a codeshare connection routed through its network; Iberia and Lufthansa also appear as interline partners rather than operating daily metal of their own on this specific pairing. A practical note worth flagging: most transatlantic arrivals into London Heathrow land at Terminal 2 or Terminal 3, and passengers continuing onward should budget at least ninety minutes for connections given immigration queues for non-EU arrivals. Fare patterns on this route tend to favour bookings made in late winter or early spring for summer travel, with shoulder-season departures in April and October typically offering the most competitive premium-cabin availability.
