London to New York is the world's most iconic transatlantic route, operated by over a dozen airlines with hundreds of weekly departures from London Heathrow (LHR), Gatwick (LGW), and London City (LCY) to New York JFK, Newark (EWR), and LaGuardia (LGA). The westbound flight takes approximately 7 hours 30 minutes to 8 hours (longer than eastbound due to the jet stream). Economy fares start from around £280–£350 return booked well in advance, while peak summer and holiday prices can exceed £800 return. This guide covers every airline, both London and New York airport options, how to find the cheapest fares, and the best things to do in New York City.

Quick Facts: London to New York

All Airlines Flying London to New York in 2026

London Heathrow vs Gatwick — Which to Use?

Most flights to New York depart from Heathrow (LHR), which has the most carriers, most daily departures, and the best connections from within the UK. Key differences:

• Heathrow (LHR): 26 km west of central London. Served by Elizabeth line (27 min to Paddington, £11.80), Heathrow Express (15 min, £25), and Piccadilly line Underground (50 min, £6). Terminals 2, 3, and 5 handle most New York flights — check your terminal when booking and note that Terminal 5 is exclusively British Airways.
• Gatwick (LGW): 45 km south of London. Gatwick Express train to London Victoria (30 min, £19.90). Fewer New York flights — Virgin Atlantic, Delta, and Norse Atlantic use Gatwick. Usually cheaper fares but less convenient location.
• London City (LCY): British Airways Club World operates London City to JFK — a premium niche service popular with business travellers from east London and Canary Wharf. Small airport, very easy to use, but limited to business/premium passengers on this route.

New York JFK vs Newark — Which Airport?

Most transatlantic flights from London land at JFK (Queens, New York) or Newark (New Jersey). The difference matters significantly for your onward journey:

• JFK: Serves all five boroughs of New York. New AirTrain + LIRR/Subway combination to Manhattan takes 40–75 minutes and costs $10–15. Taxi to Midtown Manhattan is around $70–85 plus tolls (fixed metered fare). Most convenient if your hotel is in Manhattan.
• Newark (EWR): New Jersey side of the metropolitan area, technically faster to reach from Midtown Manhattan by NJ Transit train (30 min, $17) from Penn Station, but requires getting to Penn Station first. Taxi/Uber to Manhattan is $55–80 plus tolls. Good option if staying on the west side of Manhattan or New Jersey.

ESTA — Electronic Travel Authorization for UK Citizens

UK citizens (and most other nationalities in the US Visa Waiver Program) must obtain an ESTA before travelling to the USA. Key facts for 2026:

• Cost: US$21 per person (increased from $14 in 2024)
• How to apply: Online only at esta.cbp.dhs.gov — the official US government site. Beware of third-party sites charging inflated fees (US$60–90) for the same service.
• Processing time: Usually approved within minutes to 72 hours. Apply at least 72 hours before departure to be safe.
• Validity: 2 years or until your passport expires, whichever comes first. Allows multiple visits of up to 90 days each.
• Who doesn't need it: US citizens and permanent residents (Green Card holders). Non-US citizens from countries not in the Visa Waiver Program need a full US visa — check the US State Department website for your nationality.

How to Find the Cheapest London–New York Flights

• Book 3–6 months ahead: Unlike some routes, transatlantic prices tend to increase significantly within 3 months of departure. The cheapest fares are released 6+ months out.
• Travel shoulder season: October–November and March–April offer the best combination of lower prices and good weather in New York. Peak summer (June–August) and Christmas are consistently the most expensive periods.
• Check Norse Atlantic first: For budget-conscious travellers, Norse offers genuine savings over legacy carriers. Their sale fares can be under £150 one-way — even adding a bag and seat, often still cheaper than the cheapest BA or Virgin fares.
• Use Google Flights date grid: Search London to New York on Google Flights and use the calendar/date grid view to see the cheapest days across an entire month at a glance. The cheapest departure days are typically Tuesday and Wednesday.
• Consider flying into Newark: Newark (EWR) fares from London are often £30–80 cheaper than JFK on the same dates, and United Airlines has a strong Newark hub with excellent onward connections.
• Aer Lingus via Dublin: Aer Lingus flies London Heathrow to JFK via Dublin, where you clear US customs and immigration in Dublin (the airport has US pre-clearance facilities). You then arrive in the USA as a domestic passenger, avoiding JFK international arrivals queues. This can be significantly faster on busy summer days.

Top Things to Do in New York City

• Central Park: 843 acres of urban parkland in the heart of Manhattan. Free to enter. Highlights include Bethesda Fountain, the Great Lawn, Strawberry Fields, the Conservatory Garden, and the Reservoir. Rent a bike to cover more ground.
• The Metropolitan Museum of Art: One of the world's great art museums with 5,000 years of art across 17 departments. Pay-what-you-wish admission for NY residents; fixed admission for others (around $30). Allow a full day.
• Brooklyn Bridge and DUMBO: Walk the Brooklyn Bridge from Manhattan to Brooklyn (30–40 minutes, free). DUMBO (Down Under the Manhattan Bridge Overpass) in Brooklyn offers the iconic Manhattan skyline and bridge view photo spot on Washington Street.
• High Line: An elevated park built on a disused 1930s rail line through the West Side of Manhattan. Free, open daily, 1.45 miles long. Start at Gansevoort Street and walk north through Chelsea to Hudson Yards.
