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.

Dreamliner is an excellent aircraft. Great seats in business. Flight attendant Alex had a bored, sullen attitude in serving customers. Difficult to get his attention and very slow to respond to a simple request for water. Spoiled the experience a bit as the AA motto is “we’re here because of you”. Attitude needs some adjustment!

Dreamliner is an excellent aircraft. Great seats in business. Flight attendant Alex had a bored, sullen attitude in serving customers. Difficult to get his attention and very slow to respond to a simple request for water. Spoiled the experience a bit as the AA motto is “we’re here because of you”. Attitude needs some adjustment!

The best part was the staff. They are kind and gracious and made it a good flight.

Reasonable price, great service, highly recommended. i arrived well rested!

It is good. The aircraft is big enough for my legs. Just not that cold enough and food is not that good. There was a food that was supposed to be beef, but only onions, no beef inside.

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.

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

Though the flights to and from Tokyo were the longest (and some foods I found a little bit unappetising, but some I liked), and Osaka to Tokyo was very short (therefore no food or entertainment), I kinda enjoyed them and might use them again if I go to Japan again at some point in the future

Very nice staff and very good choices for food and drinks.

The flight took off at 10pm in Singapore (which is not an issue). However, the breakfast was served at 2:00am Singapore time to ETA of 5am SG time. Hence, it was difficult to get much of rest or sleep during the flight.

I was expecting to fly in a Japanese airline because that what I bought, very disappointed finding out the change of airline without any explanation.

The stewardesses were excellent! The food and service were great. I will definitely fly ANA in the future.

Excellent. There were setbacks, but it had nothing to do with the crew. Mostly, mechanical which delayed our flight.

Awful. They cancelled my flight from Osaka to Tokyo and did not communicate this with United so my flight was never rescheduled. I had to call United myself who, after being on hold with them for an entire hour, did not believe that my flight had been canceled because ANA never reported this. ANA themselves refused to rebook my flight. United then said they would only rebook my flight for $600. After three hours of calling I was able to rebook my flight. My total trip was delayed 7 hours.

Best service! Food was Japanese fine dining and they even sang happy birthday to me since it was my birthday halfway through the flight. Bed was comfortable and cabin was quiet.

Everything was excellent. Only the fish entree in the Japanese meal was overcooked and quite dry but everything else was great

Incredible. Amazing legroom. Over head fans for each person. Tv screens were great. Headphones were adequate. Seats were comfortable and spacious. Loved it.

Although I am a lifetime Gold Premier member on another airline association, I was placed in a inside passenger seat on both legs of my journey from SFO to HKG and onward to NRT. However, i was lucky enough to have befriended two other passengers (who were related) in my row (row 62) and therefore was kept entertained with conversation for a large portion of the overnight flight from SFO to HKG. Normally, on a Star Alliance carrier, I typically can have the seat of my choice (aisle seat) and also a Premier seat (wider and longer legroom). I was a bit disappointed that no recognition of my Gold Premier status was acknowledged by Cathay Pacific on either of my flights on Sept 26-27. The food was actually very tasty unlike the typical economy class menu. Also I appreciated that the dinner drinks were served first (prior) to the main meal on the HKG to NRT portion of my flights but drinks were served AFTER the meal had been distributed (less appealing for thirsty passengers). I was happily that there appeared to have ample cabin space for most everyone's bags ---although I did have to pay more than $400 in extra baggage fees as I had brought 4 bags with me Overall, I was impressed by the diligence and professionalism of the flight crew.

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

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 !

Very good baggage check and boarding pass service at Heathrow. Boarding was well organized, given the number of passengers. Food was very good. Cabin temperature was lower than expected and we were not prepared. Overall good experience.

one meal and one breakfast or sandwich instead of two meals.

Many issues arose with the plane and after 3 hours of delays, we had to return to the London airport as the plane was unfit to cross the ocean. It was highly concerning that this aircraft was in operation with so many problems.

You're asking 2 different questions. The flight from Los Angeles to London (and from London to Faro) was on British Airways. Those flights were awful. The app didn't provide detailed information, the WiFi that I paid for didn't work, the form I had to fill out to re-enter the UK was not communicated clearly so I nearly missed my flight. British Airways is significantly behind every other airline I've traveled in every way. American Airlines flight form London to Los Angeles was great. In the future, I will avoid flying British Airways when I can.

Premium economy was not what was shown, no leg riser, seats were broken and do not recline more than economy, food, we couldn't eat it was so bad, no menu 1 item and it sucked.

Our original flight was cancelled. This was a slightly earlier flight. We were business class and it was very good. The staff were marvellous and very helpful. Pity our baggage didn't make it!

British Airways is very good... Taxiing after landing took 35 minutes, can't really blame the airline but the terrible infrastructure at JFK.

Our section of the aircraft in premium economy was very cold. We asked the attendants twice to raise the heat but it never happened. Even with the blanket it was chilly for 10 1/2 hours

Really slow transfer after getting off the plane at Manchester, and lost luggage! Take the train, terrible experience on arrival

The flight was canceled and I was directed to Air France two days later than my plan departure day. This involve getting two more days of hotel and also not being able to get a boarding pass until I got to the Istanbul Air France boarding desk. It has been a troubling time.
