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.

I felt that the customer service improved compared to a several years ago.

I traveled business class from Lax to Narita flight Jl61. The crew was attentive and polite. Food was good quality and service was as it should be. Narita to Bengaluru Jl753was another story in business class. The cabin was darkened for the 9hr:30min flight, food was mediocre, service was below standard and crew can't speak English to save their lives. When you ask for noodles soup from Ala carte they gave cup of noodles while Lax to Narita i was served the best Ramen noodles in a big bowl. Why the disparity on this leg of the journey.....or is it because there were mostly Indian passengers and it really did not matter to Jal to bother as its a poor country and Indians refrain from speaking up? A good airline but differentiation like this brings their reputation and business down.

Japan Airlines was excellent as usual once on the plane. Cabin crew was wonderful as usual. Boarding was solid on the Honolulu leg. For Thai Airways the boarding was less organized. I was in an earlier group but they weren’t clear with the numbers or instructions. Flight crew from Japan to Thailand was very good.

Terrible. Our flight was delayed by 15 hours. We lost a full day of our vacation.

highly recommend for trip to japan only reason why i gave good not excellent is because their selection of movies and tv shows in English is more limited .

We asked for Hindu vegetarian meal in advance and the quality of the food was horrendous. Never flying JAL again!

Japan airline is excellent service .I recommend to Kayak and Japan airline to Frend.

Overall a great experience. One complain was the vegetarian food that my wife had which was mostly boiled vegetables with not much flavor.

Very accommodating and kind airline crews. The plane is also big which makes the passengers more comfortable and relax

I actually didn’t make it onto the flight. I spent quite a few hours trying to rebook the flight just to get screwed out of $5000. Fun!

First time tying out business class with this airline, hat a disappointment, never returning. We didn’t get the meal as requested from Singapore to HKG flight. While meals served connecting flight, crew takes meal order based off passenger membership status by giving the. Priority selection of meals. It was a battle, plain disappointment, not worth the hype, price, class as categorized/ advertised

Leg room wasn't that great. Other than that it was a good flight

Issues: 1) the charging issue as described in my previous survey 2) when I requested diet coke during the breakfast time, it is not available. Why? I can't drink diet coke in the morning? 3) when I tried to transfer to this flight, its gate information was not available to me?

Close to excellent. The only problem is when I try to charge my phone on the USB in front of my seat, the battery level is decreasing rather than increasing. Why?

The lead business class attendant was excellent. Made a point of greeting you and knowing your name by the time you leave.

Chicken pieces were too big with pasta. Need to be smaller.

Seats in the absolute back row of the plane even though we booked ages ago :( Crew was awesome though

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.

Small plane with only two lavatories at the back. You must have a good plan to use it before or after the meal, if you make a bad decision, you will end up with standing in front of the toilet for a while till the food carts empty. The good thing is even there’s a slightly delayed, the plane is still arriving on time which is superb!!

The only personel that smiled at all were the flights attendants. Desk agents, lounge people none of them had a smile or even a hello. They were like dealing with dead fish. Again flight attendants were good. All other personnel looked like they didn’t want to be there or help.

good flight. food is only so so. I actually did not eat the snack. it does not look too good on the passenger next to me.

Food no variations only beef of chicken no veggie meals

Super surprised with the entire experience. Business class is incredible. Flight attendants around the world could learn customer service from these people. Simply fabulous experience all the way around.

Pillow and blanket are dirty. My son got multiple bites during the flight

Flight was on time. My group paid for seat’s so that us four can be seated next to each other. We all got separated. We all got middle seats, which made it more difficult to be able to get up and stretch or use the restroom. We tried talking to the employees at China Eastern and they were of no help. We will not be taking this flight or recommend this route to others in the future. Also I will be contacting customer service on how I can get our money back for paying for assigned seats.

China eastern was fantastic. I had read so many bad reviews that had made me nervous. However, I found that the flight attendant’s, and customer service check in etc. etc. was excellent. I had no problems. I would fly with them again!

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

Excellent experience however older aeroplanes used by China Eastern Airlines.

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

cannot get seat information for LAX to IAH when check in in XI,AN

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

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

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.

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

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

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.

Food & service very good next I will pick up again

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!

The boarding process was chaotic at LHR and the seat was not as comfortable as other airlines....

Great flight. One unique individual assisting in business class who should have not been there. Need more generic meals, not British centric.

We always use BA due to the direct flight options, we have always had a pleasant flight with BA.

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

Unfortunately, my flight was cancelled because of some sort of emergency over the Atlantic and had to return to London. While I think British Airways made every effort to mitigate the situation, I must say it was still pretty unpleasant. I do appreciate the fact, however, that British Airways put my safety first…and I think the effort to correct a bad situation was very sincere. But I think the process might be handled better in future.

Horrible leg room - coach seating with empty seat in middle on a 3 across seating. You buy business class for comfort which includes leg room. Absolutely no entertainment options either. Awful experience

Crew service was poor and very little difference between premium economy and economy. Disappointed.

My bags never made it on the flight and I now have to wait for them to arrive hopefully tomorrow. You can’t even track your bags in the app to see where they are since they didn’t arrive. You have to file a claim and then wait for them to inform you when you will receive your bag. We were already delayed for an hour due to baggage so I don’t understand how my bag didn’t make the flight.

One of the worst experience given the middle seat even asked for the change no one honored,boarded at the end and overall one of the worst experience

No WiFi in either flight. No leg room, the seat in front of me left dents on my knees and the tray was so low my knees propped it up if I tried to use it.
