Cheap Flights London to New York: How to Fly the World’s Busiest Transatlantic Route for Less

Check live London–New York fares on TopTravelCentre →

Cheap flights from London to New York are the most contested seats in the sky. Dozens of daily departures, five competing airlines in economy alone, and a fare war that never quite ends mean round trips realistically start from £280–350 if you know when to look. Search and book your flight on TopTravelCentre — on this route, waiting even a week can add £100 to the same seat.

Airlines flying London to New York

This corridor has more nonstop competition than any other transatlantic route, and that is great news for your wallet:

British Airways and Virgin Atlantic — the full-service flag carriers, up to 8+ daily departures combined between them, from Heathrow.
American Airlines, Delta and United — US legacy carriers flying nonstop from Heathrow (and United from Gatwick seasonally).
JetBlue — the disruptive low-cost entrant, flying Mint-configured A321s from Gatwick and Heathrow with genuinely cheap economy seats.
Norse Atlantic and other low-cost long-haul — budget nonstops from Gatwick, with basic fares that undercut legacy carriers by £50–150 if you travel light.

Connecting options (Aer Lingus via Dublin, Icelandair via Reykjavik, TAP via Lisbon) are sometimes £80–150 cheaper, but on a route with this much nonstop competition, they rarely justify the extra 3–5 hours unless you’re very flexible.

Departure and arrival airports

From London you have real choice, and the fare gap between airports is often the biggest single saving available:

Heathrow (LHR) — most flights, most frequencies, best for connections; also usually the most expensive.
Gatwick (LGW) — JetBlue, Norse and some Virgin departures; frequently £40–80 cheaper than Heathrow on identical dates.
Stansted and Luton — occasional seasonal or indirect options; check but don’t expect nonstops.

Into New York, there are three realistic doorways:

JFK — the main international gateway, best AirTrain connection to Manhattan (~35 min to Penn Station area).
Newark (EWR) — often cheaper, 45 min to Midtown by rail; the fare gap versus JFK is regularly $50+.
Always compare both. On this route the cheapest combination is often Gatwick–Newark, while the most convenient is Heathrow–JFK. Only you can price your time.

When to fly: cheapest months for London–New York

The seasonal pattern is reliable year after year:

Cheapest: mid-January through February, and early-to-mid November. Round trips from £280–330 are realistic.
Shoulder: March–April and late September–October. Fair balance of weather and price, from £350–450.
Most expensive: late June–August, Christmas and New Year. Expect £550–800+ unless you book very early.

Flying Tuesday to Thursday instead of Fri–Sun typically shaves another £30–60 per round trip. The flight itself takes about 7h30m westbound and 8h+ eastbound, so an evening departure from London lands you in New York the same evening — a good trick for maximizing a short trip without a hotel night.

Money-saving tips for this route

Set fare alerts on both LHR and LGW. The same airline can differ by £60 between London airports on the same day.
Book 6–10 weeks ahead. Transatlantic fares on this corridor bottom out around two months out; booking 6+ months early usually means paying the planner premium.
Fly into Newark when Manhattan isn’t the final stop, or when the fare gap exceeds $50 — the rail link is fast and cheap.
Travel with hand luggage only on low-cost carriers. A checked bag on a budget long-haul can erase the entire saving.
Check the return from New York separately. Ex fares starting in London are not always symmetric; occasionally a simple date shift on the return saves more than changing the outbound.

Practical details that affect your fare

Every nonstop on this route is a wide-body with seat-back entertainment, meals and a checked bag included on legacy carriers — the low-cost operators unbundle all three, so build the full cost before judging the headline price. Westbound flights run about 7h30m with a five-hour time change, so an 11am London departure lands in New York around 2pm — ideal for a hotel check-in. Eastbound overnight flights are the classic choice: dinner, sleep, and a morning arrival in London with the whole day ahead. For immigration, US-bound travellers should allow three hours at Heathrow or Gatwick, and remember your ESTA must be approved before boarding, not just applied for.
