Top tips for finding cheap flights to London
- Book at least 3 weeks before departure in order to get a below-average price.
- High season is considered to be June, July and August. The cheapest month to fly from the United States is February.
- Enter your preferred departure airport and travel dates into the search form above to unlock the latest London flight deals.
- Landing at any of the six international airports in London guarantees an excellent traveling experience. These airports have passenger assistants to help travelers navigate the airports and special assistance programs for those who need extra help. Programs like the Sunflower Lanyard at London Luton Airport or the Blue Band scheme at London Southend Airport help airport employees identify travelers needing additional assistance.
- When traveling with a lot of luggage and you are flying to Heathrow Airport, you could request porter services available at the airport. You can hail a porter in the baggage halls, and you will receive assistance with your luggage. Porters charge $32 for 1-8 bags and work from 6 am to 9 pm.
- Are you landing at Heathrow Airport? If you would like a quiet place to meditate, take advantage of the multi-faith prayer rooms available. You can find the rooms at Terminal 2 Gate A21, Terminal 3 Gate 24, Terminal 4 Mezzanine Level, Terminal 4 Gate4, and Terminal 5 Gates A8, B34, and C52.
- Inter terminal movements are often unavoidable. If you land at Heathrow airport, you will need to obtain a free inter-terminal ticket from one of the machines at the station to use the airport shuttles. If you have a connecting flight at Heathrow, you don't need to use the shuttles. The airport has frequent flight connections and buses to take to the next terminal without leaving the passenger-only area.
- If you love animal therapy, you should consider landing at London Southend Airport. The airport has partnered with Essex Therapy Dogs to provide therapy dogs. These dogs roam around the airport's terminals seeking to ease the anxiety and stress travelers face.
- Flights to London can land you in any number of airports serving the greater London area. Six international airports service London and, in terms of number of passengers served, they rank as follows: Heathrow Airport, Gatwick Airport, London Stansted Airport, Luton Airport, London City Airport and London Southend Airport. Lucky travelers flying to London have a plethora of options.
- Perhaps the most popular airport, Heathrow easily connects to the London Underground and can be reached via the Piccadilly Line. Travel time should be under an hour and a single-way fare will be upwards of six pounds (around USD $8.00). Heathrow has three separate stations on the London Underground: one for terminals 2 and 3 and one each for terminals 4 and 5.
- The Rest and Relaxation Room in Terminal 3 of Heathrow Airport is perfect for travelers stuck with a long layover. Snack machines, sofas, and lounge chairs will tide the weary traveler over until boarding time in this free and oft-visited lounge. For travelers willing to pay for premium service, there are a variety of other lounges that offer private rooms, showers, and fully equipped bars.
- Landing in Gatwick Airport? There are several popular ways to reach the city from the airport. Trains run to London Bridge and Victoria, and many locations around the city are reachable by London Blackfriars. As if that weren’t enough, coaches and shuttle buses offer service to a number of other locations across the city.
- If duty-free shopping is one of the perks of traveling for you, then Heathrow is definitely the airport to head to. Not only do they have an extensive range of luxury stores and products, but pre-ordering purchases a day in advance also saves you time, as it allows you to skip the lines. Heathrow Reward members earn points with every purchase as well. These points can later be redeemed for miles and many other perks.

Airline reviews
Cons: "JetBlue is awful. TVs don’t work. Staff isn’t friendly"
Cons: "JetBlue is awful. TVs don’t work. Staff isn’t friendly"
Pros: "Crew was courteous and gave constant updates in regards to any delays."
Cons: "Flight was delayed and there was congestion prior to take off. Not sure there was anything that could’ve been done."
Pros: "The crew was ok."
Cons: "We wait too much, at least someone should have told the reasons for the waiting."
Pros: "The inflight crew was absolutely incredible. They were funny and helpful especially as our situation was incredibly bad."
Cons: "After waiting almost an extra hour plus for a delay, the boarding process was complete chaos. Not to the fault of the crew at LaGuardia, but just based on the annoyance and impatience of the passengers waiting to board. Once on the plane, our row was the only one with broken TVs. Unfortunately for my husband and myself, we were flying with two toddlers with whom we had solely expected to entertain with the TV."
Pros: "The personnel were courteous and listen to your request ,the flight was exceptional.."
Cons: "No comments at this time."
Pros: "Leg room and tv"
Cons: "Increased cost of luggage, snacks , and perhaps a little more info about the flight delay"
Pros: "Great service. Also loved the size of the seats and the leg room that I had."
Pros: "Free unlimited snacks! Lots of leg room"
Cons: "No safety video. Airport terminal was very small and stuffy. Security line was long"
Pros: "Boarding was a bit delayed in the beginning but back on time very quickly, seat comfort and legroom was great. Loved that I got a full sized can of soda, that's always fantastic and snacks were fine."
Cons: "My Seat 23D had a defective TV, so it was flashing on and off constantly throughout the whole flight, usually I don't have an issue with the entertainment because I like to sleep during flights, but due to some turbulence I was awake for part of the flight. Unfortunately with the flashing TV it gave me pretty bad nausea to the point of wanting to vomit, this is the first time I've experienced anything like this on a plane, was definitely looking forward to landing so I didn't have this nauseating feeling anymore. I have a video of the issue if anyone at Jetblue was interested in seeing. It was flight 499 from LGA to Orlando on 9-16-18. Thanks."
Cons: "delays, crying children and sniffling sneezing passengers. Restroom was dirty."
Pros: "Entertainment"
Cons: "I requested a vegan vegetarian meal and did not get it. I had to do with the regular meal which had a lot of dairy products to which I am allergic to. The space between rows of seats. It was really crammed in Economy and we are a petite thin family!"
Pros: "The crew was very nice."
Cons: "The seats had such little cushion that it made the flight extremely uncomfortable."
Pros: "Good crew, food was good for airline food. Entertainment offerings were good."
Cons: "Too many seats, 3-4-3 configuration means not even enough room to walk down aisle without bumping people in their narrow seats."
Pros: "Amazing - they had a full dinner for a 9:55pm flight, with real silverware, complementary alcohol, for economy passengers! Crew extremely professional and efficient."
Pros: "Crew were great"
Cons: "Cabin kept very hot, very difficult to sleep. Seats were so-so comfortable"
Pros: "Orderly boarding process. Considerate reseating when bulkhead with extra legroom were not usable."
Pros: "I did not receive a single email from kayak letting me know I could check in or select seats. No updates on flight status! Poor service!"
Cons: "Email updates before flight! Not a single email sent!!"
Cons: "It would have better if the flight wasn’t 5 hours late."
Pros: "Good entertainment options"
Cons: "two of the three phone charge ports were not working I think the passenger seating areas may not have been deep cleaned"
Pros: "Smooth transfer from Terminal 3 to the International Terminal. Great airport. Easy boarding, friendly crew and very smooth flight."
Cons: "I was very happy with my flight experience with Swiss."
The staff was very professional, the places very clean. The legroom was a little bit tight but so worth the price of the flight. Very pleased! Next time, I want to book a stayover to explore Iceland :)
The boarding process was easy, the crew was friendly and the flight was very smooth. There is a limited menu the food was tasty, but you have to purchase everything. The cost of the flight was very reasonable but everything such as baggage is extra.
Play is a great budget airline. There are no TVs or chargers in the seat but there was more legroom than expected. Boarding and all staff that I interacted with were great. You have to pay for any and all drinks or snacks you might want on flight.
Play is a great budget airline. There’s more legroom than expected, no TVs or chargers in the seat, all staff that I interacted with were great.
Blood sucker budgeted airline. Charging after and after. No one should busy air ticket in this airline. Completely a scam and sucking blood.
The cabin crew very kindly arranged a change of seats for us due to a distressed passenger
There was no food or entertainment. That was fine, not a problem. I paid for “priority boarding” ( and a cabin bag) but there was no “priority boarding.” That was disappointing and falsely advertised so perhaps that could be adjusted.
No frills airline. Excellent service. Very good leg room for passengers compared to other "full service" airlines. Crew was very friendly. No entertainment system other than flight information display which was surprising as I thought it would be another revenue stream for them. Overall a surprisingly excellent experience.
Great new carrier to Europe. Lots of leg space and friendly crew
Worst seating -- by several orders of magnitude -- on any aircraft in sixty years of flying regular and budget airlines. The seats are cramped from side to side, barely padded, short from back to front. Tightness was at first absurd and then actually painful for a five-to-six hour flight. Pitch between rows is so small that even turning to stand up to get into the aisle is difficult. And I'm a slender guy, 5'9", 170 lbs. Website for booking held many "mysteries" like hidden access to payment portal. Though one screen said my booking and payment were complete, I learned at the airport that "complete" was not true. Had to work with helpful supervisor at the check-in desk Online I was able to change my flight booking from Saturday to Friday, But also I learned at the airport (too late) that the carry-on bag fee from the Saturday flight did not automatically shift onto the Friday flight. I had to pay the much higher at-the-airport charge, 49 euros. I will try to get an adjustment.
Pros: "Crew are always top notch, free drinks are readily available and entertainment system is great."
Cons: "The food portions and quality have definitely declined over the years sadly, as carriers cut costs no doubt."
Pros: "Amazing crew, excellent drinks and decent food. Very comfortable seat"
Cons: "Everything was great"
Pros: "Crew was great !!!"
Cons: "Seating in upper class is uncomfortable and bedding is not fresh."
Cons: "I cancelled this flight online, then I called to let them know I was getting emails, but that I had cancelled. For two days I received emails about delayed flights and now this."
Pros: "The business class seats are the best we’ve had. Plenty of room, nicely laid out, good organization design. The blankets were fluffy and very comfortable. Crew was super attentive and friendly. For such a long flight, it was very pleasant, will highly recommend."
Pros: "The crew were very attentive, they tried hard to help me with comfort, drinks etc. I didnt have food as it was so good in the Virgin Clubhouse!"
Cons: "The bed! When you flip it flat its rock hard, and the matress they provide is useless! Need foam matress to really make it more comfotable. If the seat reclined another few inches i wouldnt bother flipping it."
Pros: "Boarding process was very efficient and crew was very pleasant and helpful. Seats were reasonable for economy."
Cons: "Meals were very small but tasty. Movie options were random but enough to keep you occupied."
Pros: "The flight itself was good! The one from London to Delhi was better than from JFK to London"
Cons: "I wasn’t told about my baggage were being delivered through different airlines the other day!"
Pros: "Food was delicious, consistent timely service and excellent entertainment options onboard. The flight was an hour early!"
Pros: "The flight felt so short, service was amazing, food was good. Great overall experience."
Pros: "Not one of my good experiences with Delta. Two hours delay in the flight"
Cons: "Information on the flight delay as communication was. at least very poor. Also A 220 was ok but First Class was so so"
Pros: "Cabin crew and entire experience was phenomenal. Cannot recommend Delta more!"
Cons: "Nothing"
Pros: "The crew was very attentive and had great personality. They anticipated any needs we had."
Pros: "Crew, food, flight."
Cons: "Could always use a wider seat. I just hate having my hips touching a stranger for the whole trip."
Cons: "Really packed together seats...more room. Crew spoke very loudly on plane...jarring"
Pros: "It’s nice to be in a plane fitted with modern conveniences. Great entertainment options."
Cons: "I didn’t have a window at all. The staff didn’t offer any snacks to us. My bag was the only one that didn’t make it while I had a plenty long layover."
Pros: "Horrible delay with unruly customers on the plane. But the flight attendants did great handling them"
Cons: "sat on the tarmac for 3 hours because the pilot was late."
Cons: "The entire time there was a clogged bathroom smell coming in waves. The crew was forgetful of requests. Not a pleasant flight."
Pros: "The crew was communicative and courteous."
Cons: "There was a flight delay in LAX due to a maintenance issue. The captain and crew informed us before we boarded the plane which was excellent. However, they could not figure out what was wrong with the planed and delayed the boarding for another 3 hours, putting our 1900 departure time to 2100."
