Top tips for finding a cheap flight from London Heathrow Airport to Japan

  • If you're planning flights from London to Japan, you'll typically have the choice of three airports in London to depart from for this route. London Heathrow Airport (LHR) offers more frequent options and is a much larger and more established airport, which often leads to longer wait times. London City (LCY) operates some of the quickest flights with a single stopover in Amsterdam and is also the closest airport to the city centre. If you're flying to Haneda, London Gatwick (LGW) or London City are the best options.
  • The three most well-known and major airports in Japan are Narita International Airport (NRT), Haneda Airport (HND) and Kansai International Airport (KIX). The first two are based in Tokyo and the best choices if you're heading to the city or visiting eastern Japan, while Kansai is based in Osaka and serves Kyoto and western Japan.
  • If you're flying to Tokyo, you'll find that the most frequent flights head to Narita International while only a couple of flights head to Haneda. Flights to Haneda are typically more expensive and the airport is also much busier than Narita, which could mean longer wait times.
  • Kansai Airport is very accommodating when travelling with children. The airport offers a wide range of services and facilities, including a kid's play area at the International Gate Area Centre, baby rooms with baby-changing facilities, loaner strollers, baby chairs and children's seats.
  • If you're flying from London to Haneda, the most common airlines operating this route are Japan Airlines and Turkish Airlines, making them a safe bet if you're on a tight schedule.

The crew assisted the super senior citizen and accommodated her requests. Experience with crew was excellent. However the aircraft did not have a separate business class cabin. Some of the small offer to improve confirmt of passenger like making a bed in helping them sleep, closing the cabin door would go a long way as some of the traveler are not even aware of these facilities. Once they know, they may prefer flying business.

Since I traveled on my birthday, they gave me a gift and a card. How thoughtful and caring.

Delightful. Excellent service, excelling cabin, could never fly coach again! 😎😆😉

Our flight was canceled, then they moved us to a different flight number yet we didn’t receive notifications timely. We had to find out the latest on our own / later AA sent a text with the updated info..

They didn't tell me they changed my flight. So I got confused on what happened to my flight.

Great flight experience although the food served was not up to the usual SQ standards with the main being too saucy.

There were no vegetarian options on flight from India. Then on the next flight there was no chosen entree available. Movie selection was mediocre

It was fine but my trip from Narita Japan to L.A kind of mediocre because did not get the assigned window seat.

It was good overall. What I liked most was the restrooms. Compared to other airlines, the restrooms seem larger and look clean. The seats also look clean. The attendants are nice, except one time during the flight. I was sitting on aisle and a man sitting window. He asked an attendant for a snack. She told him to go ahead and get some snack from the section with food storage (I am not sure how it is called). So, I had to get up to let him get out from his seat. Why she did not bring him some snacks so that I would not have to move, I do not know... I was kind of surprised how inconsiderate the attendant was.

Although delayed leaving the crew were lovely, comfort of the seats was excellent. Cabin was a little too warm but overall the best economy flight we have taken

The go to HK trip will easily giving jetlag, but coming back to Chicago has no jetlag because of the time taking off matter.

Cathay has always been great. Even allowed some leniency on my baggage weight. I believe they are also on the more leg room side of airlines.

The only problem was my connecting flight to Chiang Mai on Hong Kong express that I booked through Cathay Pacific was canceled and I was never told about it. I was rescheduled on a flight 10 hours later. Very long day at rgr airport in Hing Kong after a 13 hour flight but that's OK, I understand things change but I think I should have been told. I would have prepared myself for a long wait. Great flights all around though. Thank you

Great entertainment system, the seat is a bit old style needs refurbishment

Boarding at the airport was not well managed. Otherwise, had a good flight sitting in the first row (which I paid for). Crew was pretty friendly, and flight was smooth.

very professional and very attentive to my Special Needs as I required a Wheel Chair and assistance to board

Crew was great. But a bit understaffed. The business class seat, etc were dated. But comfortable. Some legs had entertainment system from a decade ago. Selections were rather poor. Food was mediocre at best. Actually poor for business class standards. I liked the lounge in Hong Kong. Showers were great. Food was nice.

As a solo traveller, I always prefer to have an aisle seat, but the flight was so full, there weren’t any available. I understand that the seatbelt sign sometimes has to go on if turbulence is anticipated but after the second food service, it was on continuously for about an hour and a half and there didn’t seem to be any turbulence at all! With seats reclined, my fellow passenger in the aisle seat asleep and the seatbelt sign on I felt very trapped, extremely uncomfortable and in desperate need of the bathroom. The positives were that the staff were very friendly, the entertainment was great and we actually took off on time and arrived in HKG earlier than expected.

One of the worst flight in business class by qatar airways and I’m no stranger with qatar airways businesses class, I travelled with the extensively in the past 12 years

Very comfortable flights. Not so many new releases in terms of films.

Weren’t even given earphones to use the entertainment system

The meals were not the greatest and lacking of appetite but everything else was spot on

Overall, excellent: check-in, boarding, service, and food. The Business Class seating is a little less private and spacious than the world's premier airlines, but still very good for a long haul flight.

Your staff was exceptional. Could teach the other airlines-rules on etiquette, and service. Excellent landings on flights, carried out by your pilots. Only complaint is long delay on return flight in Beijing, onto Vancouver.

Worst than I expected, crew was not attentive, meal was as disgusting , they didn’t even drink selections as they would to other passengers. I felt discriminated

UA is ok. But check in was a very bad experience

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

Communication between the captain/crew and the passengers needs to be improved.

The flight is not bad, but the Business Lounge is not big enough for the quantity of people they accept and there is a limited options for food and beverages.

We bought premium Economy, thinking it would be more comfortable, but the seat is so narrow ,that my legs and feet are swollen , I can't wear shoes !

It was just fine. The sirlines did live up fully to my expectation.

The crew were excellent, service amazing, blankets and pillow good, cabin temperature perfect, the flight on time, food was unusual selection however plentiful, price for tickets unbeatable through Kayak. Older aeroplanes used by China Eastern was the only down side.

Better good than most, if not all European airlines. If you’re stuck in an economy seat anyways, China Eastern is a good choice because of shorter flight time, being able to overfly Russia

The temperature of the plane cabin is too hot. Sweat and uncomfortable. Also my food tray was broken down drinks fall off

Cheapest option from Gatwick £400 cheaper than Emirates and Qatar. Entertainment no where near as good as Emirates and Qatar, but saved £400 so all good.

Great staff and food. Seats pretty uncomfortable but plenty of legroom. Entertainment system outdated.

Flight was fine, however we were not able to check in online, this adds to travel stress. Luckily check-in at Heathrow was quick, but we did not get the seats we paid extra for. We paid for a window and 2 aisle seats from Shanghai to Tokyo leg, but they changed us to middle seats. Not good :(

Couldn’t fly since they wouldn’t issue a boarding ticket. Something to do with not taking the departing flight since it was cancelled due to weather. No notice or anything about the trip being invalid. The app made it seem like I was all good for it. Never trusting travel agency

2 hours delay on the 1st plane out of the day!!!!!

Multiple delays, with no explanation. Caused us to almost miss our connector. The airline made no effort when we arrived in Shanghai to help us make it to our next flight with the same airline.

It was pretty decent mostly cause I have leg room.

Flight was delayed leaving Heathrow by 1 hour. No onboard entertainment and basic food available for purchase.

because of delays of earlier flights, we did not fly BA to Reykjavik. We booked an alternate flight through Businessclass.

It was the old style business class seats which are a long way from the new ones. Also the pork-free breakfast option is always a bit disappointing!

God food! Although some of the snacks were not to my taste. Nice amenities in premium economy made for a comfortable flight. The pilot was able to make up about half the time we were delayed in the ground (we were delayed over an hour before takeoff due to a shortage of tugs) Nice movie selection for entertainment. We were last to board the second leg of our flight due to.complications during transfer from the first flight of our trip, but did manage to board in time. We really enjoyed the video presentation for flight safety. Hilarious gets your attention! Really nice, sufficient accommodations for overhead storage, didn't seem crowded or jam packed. I enjoyed being able to track the flight on my monitor. I was disappointed that there wasn't free WiFi during the flight, I thought that was a complimentary service but you had to pay extra. It felt like we were nickled and dimed on that one.

That airplane is the most uncomfortable I’ve ever flown! Flight 267 LON-PDX Aug 10, 26 The middle armrests didn’t go up all the way. The aisle arm rest didn’t raise at all. The leg room area was compromised by a large metal box on both exterior seats. The headrests didn’t flatten. We got an email apologizing for no WiFi, but on the plane we’re told there would be WiFi. I never got it to connect. Pre-boarding support was great. Boarding was smooth. Crew was great. Food was DELICIOUS. A different plane would have resulted in a much better score.

Lovely attentive staff and even though take off was a tiny bit late, the pilot landed us early in PHX. Smooth easy journey and good touchdown.

My first check in at my origin checked my visa for my international flight but it needed to be checked again. While this is understandable, I had to wait in line for 2 hours to get this second check. More agents are needed to process travel issues in Heathrow. There were times during the 2 hour wait that there was only one person servicing the long line (I don't know where the others went). There were many agents milling about but not working the desk so it seemed as if there were plenty of people at work that day. I attempted to use the automated kiosk but because I had a new visa (not one in my passport). Again, most of this was understandable travel delays but the queue processing time was just horrible.

Online check-in not available from Istanbul to Las Vegas. The check-in process at the airport was extremely and inefficient period. Took us over an hour to check in. Besides that, everything else about British Airways was good

My screen didn't work for the first 9.5 hours of the flight. The crew could not resolve. I don't watch much media so I had been really excited to relax and watch a BBC special but couldn't. Then I tried to use the online streaming on my devices - that never worked but I do have about 7 charges on my credit card that I now have to dispute with BA. Pretty annoying. Also, they ran out of meals and they served meals that had a serve by date of 1/26. But the staff were all very friendly and helpful when they could help.
