Nonstop flights between Boston Logan International (BOS) and London Gatwick Airport (LGW), when available, typically take 6.5–7.5 hours. Due to limited nonstop availability, many itineraries include a single stop (Dublin, Reykjavik, or major European hubs) and run 9–16 hours including layovers. Flights are frequently scheduled overnight (red-eye) for transatlantic efficiency, arriving in the morning local time in London. For October travel, review schedules for seasonal frequency changes and consider earlier departures from Boston to maximize same-day connections.
