New York JFK to London Heathrow Flights (JFK to LHR): Nonstops, Flight Time and Arrival

Five airlines fly JFK to Heathrow nonstop

You never need a connection on this route. As of recent schedules, British Airways, American, Delta, Virgin Atlantic and JetBlue all fly nonstop from JFK to Heathrow, with well over a dozen departures on a typical day. Most leave New York in the evening and land in London the next morning; a few daytime flights leave in the morning and land in the evening.

British Airways and American sell each other's seats as oneworld joint-venture partners, and Delta and Virgin Atlantic do the same, so one flight often shows under two airline names. Check which airline operates the flight, because that decides the terminal, the baggage rules and who handles a delay.

A one-stop fare via Dublin, Reykjavik or Boston can undercut the nonstops, but on a crossing this short a stop can add half the journey time again. Some New York to London fares land at Gatwick instead of Heathrow, and Newark (EWR) also has nonstops to Heathrow if it is closer to you. Compare the airport codes and total door-to-door time, not just the fare.

Flight time: shorter going east

JFK to LHR is roughly 3,450 miles (about 5,550 km). Eastbound flights typically take 6.5 to 7.5 hours because the jet stream pushes you along. London to New York is slower, usually 7.5 to 8.5 hours.

That makes the overnight flight short. After the meal service you may get four hours of sleep, so many regulars eat before boarding and sleep as soon as the lights dim.

Leaving from JFK

As of recent schedules, British Airways and American depart from Terminal 8, Delta and Virgin Atlantic from Terminal 4, and JetBlue from Terminal 5. JFK is in the middle of a long rebuilding programme, so drop-off points and walkways move; follow the signs and check your airline's app on the day.

For an evening flight, arrive two to two and a half hours ahead if you have checked in online, more on Friday evenings and around holidays. The AirTrain links the terminals to the subway and the Long Island Rail Road at Jamaica, usually the most predictable way from Manhattan when the Van Wyck Expressway is jammed.

Arriving at Heathrow and getting into London

Your airline decides the terminal. As of recent schedules, British Airways mostly uses Terminal 5, American, Delta and Virgin Atlantic use Terminal 3, and JetBlue uses Terminal 2. US passport holders can generally use the eGates, but New York arrivals bunch up in the early morning, so the border hall is busiest then.

Heathrow is about 15 miles west of central London:

• Heathrow Express: nonstop to Paddington in about 15 minutes; the fastest train, priced separately from the rest of London transport.
• Elizabeth line: about 30 minutes to Paddington and 40 to 50 minutes to Bond Street, Liverpool Street and Canary Wharf, and the best fit for most central hotels.
• Piccadilly line: 50 to 60 minutes, the cheapest rail option, useful if your hotel is on that line.
• Taxi or ride-hail: 45 to 90 minutes depending on traffic; easiest with small children or lots of bags.

You can tap a contactless card or phone on all three trains. Tube, Elizabeth line and bus journeys on the same card are capped for the day; the Heathrow Express is not part of that cap.

Entry rules: the UK ETA

US citizens do not need a visa for a short UK visit, but every traveller, including babies and children, needs an approved Electronic Travel Authorisation (ETA) before boarding. You apply on GOV.UK or the official UK ETA app and pay a fee. Many decisions come within minutes, but the UK government advises allowing three working days. An ETA is generally valid for two years or until the passport it is linked to expires. Airlines check it at JFK, and other nationalities have different rules, so confirm yours on GOV.UK before you book.

Keep your return booking and accommodation details handy, because border officers may ask about your plans.

When to fly and when to book

London draws visitors all year, so demand is steadier than on holiday routes. Fares are usually highest from mid-June to August, over Christmas and New Year, and in UK school half-term weeks. Late January to early March is typically the quietest period. September and October often bring mild weather after the summer peak.

London weather is changeable in every season, with rain possible any day. Summer is mild rather than hot, and winter days are short and grey, so pack layers whatever the month.

With so many daily flights you rarely need to book months ahead outside the peaks; for summer and Christmas, start looking earlier. Daytime flights are sometimes cheaper than the popular overnight ones.

Families, older travellers and anyone needing assistance

Children under two usually fly on a parent's lap with an infant ticket, and still need their own passport and ETA. A bassinet seat on these aircraft is limited and requested through the airline, so ask as soon as you book.

If you need a wheelchair or help through the airport, request it through your airline when you book, ideally at least 48 hours before departure. Heathrow provides free assistance from the kerb to the aircraft and back, and the airline arranges the equivalent at JFK. Mention mobility aids or medical equipment early so it can be loaded correctly.

If your flight is delayed or cancelled

Contact the operating airline first; it is the one that can rebook you. Keep your boarding pass, the delay notice and receipts for food or a hotel.

Your rights depend on direction and airline. Flights leaving London are covered by the UK passenger-rights rules on any airline, which can include care and compensation for long delays the airline caused. New York to London flights are covered by those rules only when a UK airline such as British Airways or Virgin Atlantic operates them. Under US Department of Transportation rules, if an airline cancels or significantly changes your flight and you decline the alternative, you are entitled to a refund. Check the UK Civil Aviation Authority or the DOT for current terms before making a claim.

If you continue from Heathrow on a separate ticket, the first airline is not responsible if a delay makes you miss it. Leave a long buffer, and remember that moving between Terminal 3 and Terminal 5 needs a transfer bus.

Time difference and jet lag

London is five hours ahead of New York for most of the year. The two countries change their clocks on different dates, so the gap is four hours for a short stretch in March and again around late October and early November. Eastbound jet lag is the hard direction: daylight, a normal local bedtime and no long nap on day one help most. The return is easier, because you land in the afternoon or evening.

Three mistakes travellers make

Forgetting the ETA and finding out at check-in. Buying a fare that lands at Gatwick without noticing. Booking the London hotel from the departure date rather than the arrival date, because the overnight flight lands the next morning. A minute spent checking the ETA, the airport code and the arrival date avoids all three.
