How Much Is a Flight to London (2026 Data)

A round trip from the United States to the UK costs about $820¹ on average right now, and London is where most of those trips go: it takes 98%¹ of flight searches to the UK,¹ and Heathrow and Gatwick together handled 91.8%² of nonstop US-UK passengers in 2025.³ That average hides a wide spread. By month the median runs from $380¹ in February to $635¹ in June. London is also one of the shortest long-haul hops from the US: a nonstop from New York JFK to Heathrow averages 6h 50m¹ in the air.

Below: fares by month, arrival airport, US city, weekday and booking week; the UK duty, US taxes and fees and Heathrow charges that sit inside every ticket; flight times in both directions; 36 years of official US-UK traffic data; and where North American visitors go once they land, in a year when US visits to the UK hit a record 5.6 million⁴.

The average fare from the US to London in 2026

So, how much is a flight ticket from the USA to the UK? Over the past month, round trips from every US airport to every UK airport averaged $820¹, a snapshot of fares seen up to late September 2026 that mixes cabin classes and does not state a sample size. Because London dominates the route, the UK-wide average is the closest reading of the price of a London trip: London takes 98%¹ of flight searches to the UK, Edinburgh 2%¹ and Manchester under 1%.¹ The low end is much lower. In the two weeks before the snapshot, the cheapest round trip found anywhere between the two countries was $149¹, Orlando to Edinburgh, and the cheapest one-way ticket listed was $172¹; the cheapest round trip to London in those five days was $289¹.¹ Those are single tickets on single dates, useful as a floor, not as a typical price.

Which London airport is cheaper?

Flights into London Gatwick average $297¹, the lowest of any UK airport, against $479¹ into London Heathrow, a gap of $183². Glasgow ($404¹) and Edinburgh ($459¹) sit in between, and Manchester is the dearest at $638¹.¹ These airport averages are much lower than the headline average because they come from a different part of the same fare pages and a different set of prices, so compare them with each other, not with the $820¹ figure.

Cheap is not the same as busy. Heathrow handled 85.8%² of the 94,784⁵ passenger flights operated between the US and the UK in 2025, counting both directions, and 38⁵ UK airports had at least one.⁵ Gatwick's low average reflects a small number of routes, several flown by low-cost carriers; Heathrow's reflects a huge network with every cabin class. From what you pay to where you pay it from: the US departure city matters more.

Where you fly from sets the price

How much is a flight to London from New York?

New York, the biggest gateway, averaged $958¹ for a round trip to the UK over the past month, $138² above the all-US average, with the cheapest ticket at $483¹.¹ That average is the best answer for a typical ticket, since London takes nearly all flight searches to the UK. New York's JFK and Newark airports had 25,568² passenger flights to and from the UK in 2025, about 490² a week counting both directions, more than any other US city.⁵

Nonstop deals exist too. In the fare listings, New York JFK-Heathrow round trips with no stops in either direction were offered at $608¹ for late January and early February 2027 and at $627¹ to $631¹ for October 2026, all below the city's $958¹ average.¹

The West Coast is where the averages split. Asking how much is a flight from California to the UK, the answer depends on the airport: Los Angeles averaged $865¹ and San Francisco $1,110¹, a $245² gap between two cities a short hop apart. Los Angeles also produced the cheapest ticket of the four cities, $289¹.¹ California matters to this route: the state is the home of 15%⁴ of US visits to the UK, and the New York tri-state area of 19%⁴.⁴

On the East Coast, how much is a flight from Boston to London has a similar answer to New York: an average of $922¹ over the past month, with the cheapest ticket at $597¹.¹ Boston also has the shortest nonstop of any US-UK route, to Heathrow in an average of 6h 30m¹.

Cheapest recent deals from each US airport

The listings below are single itineraries, the cheapest recently offered round trip on each route, with its dates and the number of stops each way.¹ They show what a good price looks like, not what most travelers pay. For how much is a flight from Chicago to London, the best listed deal was $719¹ to Heathrow for October 4 to 13, nonstop out and one stop back.¹ Chicago O'Hare had 5,936⁵ passenger flights to and from the UK in 2025, about 114² a week in both directions.⁵ And how much is a flight from Florida to London? From Orlando, Florida's main London gateway in the listings, the best deal was $453¹ to Gatwick for January 15 to February 16, 2027, nonstop both ways, the cheapest route listing in this table.¹

Stops are the hidden cost in several of these. The Newark and Seattle deals need two stops each way and the San Francisco deal two on the way back, so a cheap listing can mean a very long travel day. The Orlando and Chicago deals are the exceptions, with a nonstop outbound leg.¹ Next: when to go.

Fares by month

The UK-wide medians below are the best guide to average flight prices to London by month, since London takes almost all flight searches to the UK. February is the cheapest month, with a median round trip of $380¹, and January ($400¹), October ($405¹) and November ($403¹) are close. June is the most expensive at $635¹, 1.67² times February, followed by May at $537¹.¹

These are medians, a different statistic from the $820¹ average: for each month, prices from the past year are ranked and the middle one is taken after the top 0.1% is removed. A median is less affected by expensive business-class fares, which is why every month sits below the average.¹

Summer after June is cheaper than the peak suggests: July's median is $460¹, August $447¹ and September $452¹, and December rises to $478¹ for the holidays.¹ The price calendar and the traffic calendar do not line up exactly, as the passenger data further down shows.

Which day, which time, how far ahead

Saturday is the most expensive day to fly, at $1,020¹ on average for a round trip, while Wednesday departures can be found from $916¹.¹ By time of day, afternoon departures are the cheapest at $810¹ and evening departures the dearest at $993¹, $183² more, even though evening departures make up 55%¹ of nonstop listings to the UK (scheduled flight numbers listed on a fare-search site, including codeshares, not flights operated).¹

How far ahead to book is a noisier question. Averaged week by week over the past year, the lowest price came 26¹ weeks before departure, at $671¹, and the highest 23¹ weeks out, at $847¹. Booking in the final week averaged $794¹, $123² above the cheapest week, and booking about three weeks ahead saved about 7%¹ against the last minute.¹ The line jumps from week to week, so no single booking date is magic; the clear signal is that booking very early was cheapest.

How many flights leave for the UK each day

Airlines operated 94,784⁵ passenger flights between US and UK airports in 2025, counting both directions: about 260² a day, or roughly 130² a day each way. 44⁵ US airports had scheduled flights to the UK.⁵ Fare-search pages show a much bigger number, about 776¹ nonstop flights a day (scheduled flight numbers listed on a fare-search site, including codeshares, not flights operated): one plane often carries the flight numbers of several partner airlines, so it is counted several times.¹

British Airways alone flew 33.2%² of the operated flights.⁵ The schedule follows the seasons: August 2025 was the busiest month with 9,290⁵ flights and February the quietest with 6,052⁵; August had 1.54² times as many.⁵

New York JFK had the most flights, 18,173⁵, followed by Newark (7,395⁵), Boston (6,396⁵) and Los Angeles (6,326⁵); together JFK and Newark had 27.0%² of all US-UK flights.⁵ More flights mean more choice of times, but not automatically lower fares: New York's past-month average was above the national one.

The average flight time from New York to London

A nonstop from New York JFK to London Heathrow averages 6h 50m¹, the same as Newark to Heathrow.¹ British Airways schedules its BA178 from JFK to Heathrow at 6h 55m⁶.⁶ Real itineraries run a little longer: four nonstop JFK-Heathrow round trips listed for October 2026 to February 2027 had outbound legs of 7h 00m to 7h 15m, an average of about 7h 06m².¹

The shortest US-UK nonstops are all from the Northeast. Boston to Heathrow averages 6h 30m¹, as does New York JFK to Edinburgh; Boston to Gatwick takes 6h 46m¹.¹ Across all nonstop routes from the US to the UK, including the long ones from the West Coast, the average flight takes 9h 31m¹ and covers 4,019¹ miles (6,468² km).

The average flight time from London to New York

Going home takes longer. British Airways' return flight, BA177 from Heathrow to JFK, is scheduled at about 7h 55m⁶, an hour more than the eastbound flight; that westbound time comes from a published airline schedule read from a timetable site, not from the airline directly, so treat it as an estimate. The four nonstop itineraries listed for the coming months agree: their return legs took 8h 00m to 8h 10m, an average of 8h 05m², about 59² minutes more than the same trips' outbound legs.¹ The reason is the jet stream, which blows from west to east across the North Atlantic, a tailwind for flights to London and a headwind for flights back.

What's inside the ticket: duty, fees and airport charges

UK Air Passenger Duty

Every passenger flying out of a UK airport pays Air Passenger Duty, and the United States falls in distance Band B. From 1 April 2026, the rate now in force, an economy (reduced-rate) passenger pays £102⁷, about $137.27² at the 2026 average exchange rate; premium economy and business pay the standard rate of £244⁷ ($328.38²).⁷ The duty is charged once, on the flight leaving the UK, so on a US round trip it falls on the way home.

The rates announced for 1 April 2027 are higher: £105.33⁷ for economy and £251.95⁷ for the standard rate.⁷ Their dollar values in the table, $141.75² and $339.07², are at the 2026 average exchange rate, the latest full rate available, because the 2027 rate is not yet known. The economy rise is £3.33², or 3.3%².

US taxes and fees

The US side adds its own charges. The international departure tax and the international arrival tax are $23.40⁹ each in 2026.⁹ The September 11th Security Fee is $5.60¹⁰ per one-way trip that starts at a US airport, so it is charged once, on the way out.¹⁰ On arrival back in the US come a customs fee of $7.39¹¹,¹¹ which rises to $7.61¹² on October 1, 2026,¹² an immigration fee of $7.00¹³¹³ and an agricultural inspection fee of $3.84¹⁴, which rises to $3.98¹⁴ for tickets bought from October 1, 2026.¹⁴ Together these federal taxes and fees come to $70.63² on a round trip, and $70.99² from October 1, 2026, when both rises apply. The US departure airport also charges a passenger facility charge of up to $4.50¹⁵ per boarding;¹⁵¹⁶ a nonstop round trip has one US boarding, since the return starts abroad. With it, US government charges come to $75.13², or $75.49² from October 1, 2026.

Put the two countries together and an economy round trip carries $212.40² of government duty and fees, the UK duty ($137.27²) plus the $75.13² of US government charges, or $212.76² from October 1, 2026. That equals 25.9%² of the $820¹ average fare and 55.9%² of February's $380¹ median, a fixed cost that no sale can remove. In premium economy or business, the UK duty alone is $328.38².

The Heathrow airport charge

Airports charge airlines too, and Heathrow's charges are capped by a price control set by the UK's aviation regulator. For 2026 the cap, the maximum allowable yield, is £26.221¹⁷ per passenger, about $35.29² at the 2026 average rate, down from a maximum revenue yield of £26.927¹⁷ per passenger in 2025 ($35.52² at the 2025 rate).¹⁷ The cap limits Heathrow's average revenue from airport charges per passenger; it is collected through three charges, 58%¹⁷ from the passenger charge, 37%¹⁷ from landing (movement) charges and 5%¹⁷ from parking.¹⁷

What a US-bound passenger triggers is higher than the average. Since 1 January 2026, the charge for each passenger departing Heathrow to a destination outside Europe (the Rest of World band, which includes the US) is £49.10¹⁷, about $66.08², or £29.46¹⁷ ($39.65²) for a passenger changing planes at Heathrow.¹⁷ These charges are billed to the airline, separate from Air Passenger Duty, which is a government tax.

How the exchange rate moves the dollar price

Duty, airport charges and most spending in London are set in pounds, so the exchange rate decides what they cost in dollars. A pound cost $1.3192⁸ on average in 2025 and $1.3458⁸ so far in 2026, against $2.0020⁸ in 2007, the strongest year for the pound since 1990.⁸ At the 2007 rate, £100 of London costs cost $200.20²; at the 2025 rate, $131.92².

The long drift has been in the American traveler's favor: the 2025 rate is 65.9%² of the 2007 one. The trend line, fitted to 1990-2025, keeps falling slowly, with a wide range around it; it is our calculation, not a forecast, and exchange rates can move sharply in a single year, as 2016 showed ($1.3555⁸ after $1.5284⁸ in 2015).⁸

How many people fly between the US and the UK

In 2025, 20.18 million³ passengers flew nonstop between US and UK airports, counting both directions and all nationalities. That is 92.9%² of the all-time high of 21.71 million³ in 2019, and 2.0%² below 2024's 20.59 million³.³ In 2021, with travel restrictions in place, the route carried only 2.83 million³, 13.0%² of the 2019 level.

Over 36 years the route has doubled: 2019 carried 2.08² times the 10.43 million³ of 1990.³ The straight-line trend, fitted to 1990-2025 with the pandemic years 2020-2022 left out, keeps rising slowly to 2050; it is our calculation, not a forecast.

By month

Traffic follows the vacation calendar. July 2025 was the busiest month with 2,123,958³ passengers, about 68,515² a day, and February the quietest with 1,086,072³; July carried 1.96² times as many.³ February is also the cheapest month for fares, but June, not July, is the priciest: the fare peak comes a month before the traffic peak.¹

By UK airport and route

Heathrow handled 17.39 million³ of the 20.18 million³ US-UK nonstop passengers in 2025, 86.2%² of the total and 15.3² times as many as Gatwick's 1.14 million³.³ Manchester (903,219³) and Edinburgh (684,945³) follow, and the next, Glasgow, had only 22,201³.

On US airlines, the busiest single route in 2025 was Dallas/Fort Worth to Heathrow on American, with 732,700³ passengers.³ New York JFK-Heathrow is split between three US carriers, which together carried 998,609²; British Airways and Virgin Atlantic also fly the route but are not in these US-airline figures.

Heathrow, London's gateway

Heathrow itself handled 79.56 million¹⁸ terminal passengers in 2025, from every market, its highest total in the years shown, up from 76.02 million¹⁸ in 2019. In 2020 it handled 20.59 million¹⁸, 27.1%² of the 2019 figure.¹⁸

Americans in the UK: a record year

US residents made 5.6 million⁴ visits to the UK in 2024, the most on record, and spent £7.3 billion⁴, about $9.33 billion² at the 2024 average rate.⁴ Visits were 1.24² times the 2019 level and 2.05² times 2009's 2,727¹⁹ thousand.¹⁹ The 2024 figures come from a survey whose method changed, so the step from 2023 (5,122²⁰ thousand) to 2024 is partly a change of measurement.²⁰ No figure was published for 2020, and 2021 (663²⁰ thousand) is left out of the line.

Spending grew faster than visits. In dollars at each year's exchange rate, US visitors spent $3,230.9 million² in 2009 and $9,330.1 million² in 2024; the average visit in 2024 cost £1,301⁴, about $1,662.81², on top of the flight.⁴ Holidays made up 51%⁴ of visits and 58%⁴ of spending, with a record 2.9 million⁴ holiday visits, and about 30%⁴ of US visitors were 55 or older, against 23%⁴ for all overseas visitors.⁴

Where North American visitors go in Britain

Most visits by North American residents include London. Of their 6,447²¹ thousand visits to regions of Great Britain in 2024, 4,244²¹ thousand included London, 65.8%²; London also took 46.0%² of their nights and 57.2%² of their spending.²¹ A visit can include several regions, so the regional visits add up to more than the number of trips. The figures cover all North American residents, the closest regional breakdown published. US residents made 5,475²¹ thousand of the 6,447²¹ thousand North American visits to Great Britain in 2024, 84.9%².²¹

Scotland is the clear second, with 1,076²¹ thousand visits and 1,469²¹ million pounds of spending, and its visitors stay longer: 7.6² nights per visit against 5.5² in London. The South East (768²¹ thousand), which surrounds Heathrow and Gatwick, comes third.²¹

What these numbers mean for your trip

For a traveler from the US, the calendar and the airport move the price more than timing the purchase to the day.¹ A February trip at the $380¹ median against a June one at $635¹ saves $255² per ticket, before duty and fees are counted.

Those charges are the part that does not move: $212.40² of UK duty and US government charges on every economy round trip ($212.76² from October 1, 2026), and more in premium cabins. The pound matters too: at $1.3458⁸ per pound this year, the £1,301⁴ a typical US visitor spent in 2024 would cost more in dollars than it did at 2024's rate.

If time matters more than money, the shortest trips start in the Northeast, where Boston and New York nonstops reach London in well under seven hours; if money matters more, one-stop itineraries from the big gateways and nonstops into Gatwick carry the lowest prices in the listings, at the cost of a longer day.¹

How the UK compares with other European destinations

Measured the same way, as the past-month average round trip from all US airports, the UK is one of the cheaper big European destinations. Italy averaged $937²²,²² $117² more than the UK, and France $895²³;²³ only Spain, at $747²⁴, was cheaper.²⁴

Conclusions

1. London's price is the UK's price. With 98%¹ of flight searches to the UK going to London, the $820¹ UK average is the London average in practice; the airport choice inside London (Gatwick $297¹, Heathrow $479¹) moves the price more than the city does.
2. The cheap season and the quiet season coincide. February has both the lowest median fare ($380¹) and the fewest passengers (1,086,072³ in 2025), while the fare peak in June runs a month ahead of the traffic peak in July.
3. The wind makes the round trip lopsided. Eastbound nonstops from New York average 6h 50m¹; the westbound schedule is about an hour longer, and real return legs averaged 8h 05m².
4. A fixed slice of every ticket is set by governments, not airlines. In economy, $212.40² of UK duty and US government charges ($212.76² from October 1, 2026), 25.9%² of the average fare, is charged whatever the sale price, and UK duty rises again in April 2027.
5. Demand has recovered in visitors, not yet in nonstop passengers. US visits to the UK set a record in 2024 (5.6 million⁴), while nonstop passengers between the two countries in 2025 were still 92.9%² of 2019.
