Flying out of New York JFK
New York is the busiest international gateway in the United States, and for most long-haul corridors it is the cheapest place in the country to start. JFK and Newark function as one market: JFK carries the widest spread of foreign carriers, Newark is United's transatlantic fortress, and a fare that looks unremarkable at one airport is often materially lower at the other on the same day. That is the single biggest reason to price this route with an agent rather than a booking site — most search engines make you pick an airport before they will show you a price, so the cheaper half of the New York market never appears. Travellers across Queens, Long Island, Westchester and northern New Jersey are within reach of both, and we quote whichever one wins.
What to know before you fly to London
Entry requirements for US travellers
US citizens can visit the UK without a visa for short stays but now need an Electronic Travel Authorisation (ETA) before flying. It is applied for online and approval is usually quick, but it is a genuine requirement and airlines do check — apply through the UK government's official service, not a third-party site that charges a fee.
Best time to go
May, June and September give the best combination of weather and price. July and August are peak in both directions. January and February are the cheapest months of the year on the transatlantic corridor by a wide margin, and London is a perfectly good winter city.
Airports and arrival
Heathrow (LHR) has the widest schedule and the best onward connections. Gatwick (LGW) frequently carries lower fares on the same dates, and Stansted and Luton serve the budget European network — worth knowing if London is a stepping stone rather than the destination.
Baggage
Transatlantic economy now spans basic fares with carry-on only through to fares including two checked bags, at prices that are much closer together than they look. Matching the fare to how you actually pack is the whole game on this route.

New York to London — frequently asked questions
Fares on the New York–London route vary widely by season and how far ahead you book. We do not publish an estimate we have not measured for this pair; call our agents and they will quote the live consolidator fare for your dates.
Carriers on this route include British Airways, Virgin Atlantic, American, Delta, United and JetBlue. Others serve it on one-stop itineraries, and the cheapest is not always a name you would expect — the lowest fare we have tracked here was on a carrier outside that list more than once. Itineraries offer nonstop, on the densest long-haul corridor in the world, and total journey time runs about 6.5–7.5 hours. Which carrier is cheapest changes with the season and the fare bucket rather than staying fixed, which is why we compare them all on every quote.

Yes — this route has nonstop service, with nonstop, on the densest long-haul corridor in the world. Nonstop is not always the cheapest option: a one-stop itinerary on the same dates is frequently a few hundred dollars less, and on a journey of 6.5–7.5 hours that trade is worth pricing rather than assuming. Frequencies change by season, so call us for what is actually flying on your dates.
New York has three airports and they are not interchangeable. JFK carries the widest range of foreign carriers and almost all of the long-haul network; Newark (EWR) is United's transatlantic base and is frequently cheaper on the same day for the same trip; LaGuardia is domestic only and does not serve long-haul at all. Because most booking sites make you choose an airport before quoting, the cheaper half of the New York market is routinely invisible — we price JFK and EWR together and quote whichever wins.
Less than on the long-haul Asian routes, honestly — transatlantic economy is the most competitive market in aviation and the public fares are genuinely keen. Where we do earn our place is on the fare rules: basic economy on this corridor is restrictive in ways that are easy to miss, and the fare that includes a bag and a free change is frequently only a little more. SkyKaro's agents are reachable 24/7, and nothing is charged until an agent has confirmed the itinerary and the price with you.
