Cheap flights from London to New York

September is the cheapest month on this route, and it also sits in a sweet spot between the summer rush and the colder months, with mild weather on both sides of the Atlantic. Late autumn and the weeks after the winter holidays are quieter, while July and August fill up fast with families and long-planned trips. Flying midweek, especially on a Tuesday or Wednesday, usually costs less than a Friday or Sunday departure. If your dates land near Thanksgiving, Christmas or New Year, book well ahead, because those are the busiest days of the year for London to New York travel. The price calendar above shows fares for every month, so you can compare your own dates before you commit.

Norse Atlantic UK LTD is the name to look for if you want to fly nonstop across the Atlantic, and it works on the low-cost long-haul model, so check what the fare includes before you weigh it against a full-service ticket. Swiss, Lufthansa, Austrian, Brussels Airlines, Finnair, Iberia, Vueling Airlines, Helvetic Airways and APG Airlines all sell connecting itineraries through their own hubs, which often undercut the nonstop but add a stop and a longer travel day. On full-service tickets a checked bag and a meal are typically part of the fare, while hand-baggage-only fares strip those out. Compare the total cost of the trip, not the headline fare.

New York is served by three airports, Newark Liberty International, John F Kennedy and La Guardia, and they are not interchangeable. Kennedy and Newark sit outside the city and both have rail links into Manhattan, which suits you if you are heading to Midtown or further downtown. La Guardia sits closest to the city and is reached by bus, taxi or rideshare rather than by train. Check which airport your fare actually lands at before you book ground transport, and leave a generous margin on the way back, because traffic into the airport can turn a short hop into a long one.

Country facts: Wikidata

• Check which London airport your flight leaves from, since the city has several and they are far apart.
• Confirm the New York airport on your ticket, because Newark, Kennedy and La Guardia all appear as New York but sit in different places.
• Read the baggage rules on a low-cost long-haul fare before you compare it with a full-service ticket.
• If your trip is built from separate tickets, allow time for the connection and check what happens if the first leg is delayed.
• Make sure your passport and any US entry authorisation are valid before you pay.
• Book early if your dates fall near Thanksgiving, Christmas or New Year, when demand on this route peaks.
