Flights from London to Montreal
London Heathrow to Montreal Trudeau is a mid-haul transatlantic crossing of roughly 5,200 kilometres, with most flights clocking in around six and a half hours westbound and closer to seven on the return against prevailing headwinds. Air Canada operates the route as its home-market workhorse, typically deploying wide-body equipment such as the Boeing 787 Dreamliner, while American Airlines, Lufthansa, and Iberia serve it primarily as a connecting itinerary through their respective hubs, meaning travellers booking those carriers should budget meaningful layover time. A practical note worth keeping in mind: Montreal sits in the Eastern Time Zone, five hours behind London in summer and six in winter due to mismatched daylight-saving transitions, which can quietly compress same-day connection windows on the Canadian end. For fare patterns, shoulder season — late April through May and again in October — tends to offer the most competitive economy pricing, while business-class award availability on Air Canada is often strongest on midweek departures booked well in advance.
