Flights to London from US and Canadian Airports

The times are typical nonstop flights, not timetables, and a fare with a stop takes longer. London is ahead of every North American city, by four hours from Halifax and up to eight from the west coast, which is why most flights leave in the evening and land the next morning.

Common questions

Which US airport has the shortest flight to London?

New York (EWR) and Boston (BOS) have the shortest flights from the United States, about 6.5 to 7 hours. From Canada, Halifax is shorter still. The longest flights are from the west coast, about 10 to 11 hours from Los Angeles.

Which London airport do flights from the US and Canada land at?

Most land at Heathrow, about fifteen miles west of central London and on the Piccadilly line and the Elizabeth line. Some services use Gatwick, to the south, so check the airport on your ticket before you book a hotel.

What time should I message from the US?

London runs 5 hours ahead of you. Messages sent between about 6am and 6pm your time land during London working hours, which is when replies actually come. From the west coast the gap is wider. London runs 8 hours ahead of you. Messages sent between about 3am and 3pm your time land during London working hours, which is when replies actually come.

Do I need an ETA to fly from the US or Canada to London?

Most visitors from the United States and Canada who do not need a visa need an electronic travel authorisation, or ETA, before they fly. Apply through the official GOV.UK service only, and check the current rules before you book, because they change.
