Insights shared by verified travelers who flew the route from Dulles Intl to Japan 
Verified travelerFlew with ANA-May 2026
Definitely double check that the plane is actually what you're expecting. If it says it's operated by a different airline, treat it as THAT airline, not the one selling tickets.
JoannaFlew with ANA-Dec 2025
If you have a connecting ANA flight out of Haneda make sure it's not at a different terminal.
AhliaFlew with ANA-Apr 2025
Bring entertainment as well as it is a long flight
LayFlew with ANA-May 2024
Reserve seats in advance. This is an air ticket worth paying for, even if the price is slightly higher. The standard is consistent. Do book your layover accommodation in advance. I booked upin arrival and only got a more expensive option. Otherwise, I enjoyed very much flying with ANA and will choose it again.

Top tips for finding cheap flights to Japan

  • Japan has an efficient public transport system that the locals use to get from one place to another. To use public transport more conveniently, you should get a Japan Rail Pass or JR Tokyo Wide Area Pass so that you won’t have to pay to use the train every time.
  • Taking a taxi is often a good idea if you’re running late and need to get to Dulles International Airport (IAD) as quickly as possible. They are easily available all over the city and will drop you off outside the departure terminal.
  • To enjoy the lounge facilities at IAD Airport, consider booking your flight with United Airlines or Turkish Airlines. These are the only airlines with a lounge at the airport and also offer flights to Japan.
  • The Washington Dulles Airport Marriot is a great place to stay when you are flying out of IAD. Being the only hotel inside the airport, you’ll be less than five minutes away from the main terminal when you spend the night here.
  • When booking connecting flights, please go for the ones with an automatic transfer option. This is because the alternative, a self-transfer, will require you to check yourself and your luggage into each flight.

They broke the contents of my carry on that was forced to be checked in.

They broke the contents of my carry on that was forced to be checked in.

They forced me to check a bag. When Kayak sold me these tickets I was not informed of carry on baggage weight limits.

Great food on both legs and fast customer service from the stewardesses....

The food was great; the attendants were pleasant. Waiting to onboard felt stressful, as passengers who had connecting flights at SEA had to be verified again for two things before getting a real boarding pass: passport and carry-on luggage weight. The boarding pass issued by another airline (i.e., the first leg of my trip) did not count. The S terminal at SEA was barren, with lots of sensory overloads because every airline was repeatedly broadcasting long lists of names of passengers who had not gone through that verification process. The carry-on luggage weight check seemed futile to me. I saw a woman who opened her over-weight suitcase to move some items into her shoulder bag. She still boarded with two huge bags with her. I assume this check is an endeavor of ensuring fairness of the overhead bin space or optimizing fuel efficiency when gas price is through the roof, but I don't know if either goal is achieved. Nonetheless I respect the crew's dedication to the SOP.

Food tasted like the meat had freezer burn. Another thing all of our 4 check baggage was left somewhere and my oral medication for my diabetes was left in one of the lost luggage..most of the flight attendants did not know how to communicate in English.. the trip was a total nightmare

The crew need to be more friendly it seem everything such a rush situation during dinner and breakfast. Smiles to the passenger go such a long way just the service from Seattle to Taipei, service from Taipei to Bangkok were great more pleasant the flight attendant from Thailand she was very nice, as far as entertainment were amazing , wiffi connection was incredible great, I will be able to charged my phone from Seattle to Taipei and from taipei to Bangkok I won’t be able to do so flight attendant told me that because I don’t have the original iPhone charger connection has nothing to do what type of charger I have so she said there is nothing she can do about it. Foods : from Seattle to Taipei were ok no flavor , from Taipei to Bangkok I have chicken teriyaki the rice is overcooked all the flavor stuck on the aluminum wraps , breakfast the congee was on point and delicious. Will I recommend anyone to fly with Eva air go for it so you can experience yourself for myself I won’t fly with them again I’m gonna stick with Singapore airlines instead.

Never went. Got rescheduled with Phillipine Airlines to Bali, which was fine.

I am really satisfied with Eva Air and will definitely fly with them again.

everything was so good! Especially Food. It was the best I've ever had! However,I requested to add mileage point to Star alliance group ANA; it hasn't been added yet.... 😞

• Crew obviously hate their job • We were placed in the very back of the airplane even though we checked in 4+hrs before our flight • We were given food but since we were in the back of the plane, we were rushed to throw it away. • This was the most unorganized boarding experience. They just called “Group 1” to board and after that, it was chaos. Everyone was confused and they only spoke in Chinese.

It was so disappointed trip by unexpected company's fault delay. It had taken 3 hours delay for mechanical maintenance plus another 3 hours for bad weather.

SEA HND sector internet only worked for the last 2.5hrs of flight….. never had this kind of incident with other airlines

12 of the 14 hours were in the dark, all during daylight. Didn’t use my light because it disturbed other people it was illuminating. 14 hours sitting upright in a cramped space was horrible.

I’ve always had pleasant experiences with ANA and that has made me a loyal customer.

I like the service very much. The food just okay but maybe different culture who like, who don't like.

Seats had more space than expected. No recline, that is good.

We purchased premium economy seats 9 months ago and got bumped to economy when we tried to board the plane. It was a huge fiasco while they struggled to find us seats. I tried reaching out to Kayak to see how we can get refunded for the extra money we spent on premium but have heard nothing back. It was a 14 hour flight and were disappointed that we lost our seats after selecting them 9 months ago.

Excellent. All the ticket prices have gone up so much. With only economy as the option, I thought I better pay for a good airline and I am glad I took ANA. The only thing is the long layover at Hanaeda enroute to Singapore. Any chance to bring back the service to land at Narita instead for the transit and a shorter layover will be fantastic. I am a fan of ANA.

The flight was canceled due to a mechanical problem. The rebooked flights were snot good. Many complexities. Will not use a third party booking again.

Our flight that was before this one was delayed, and I appreciate that this airline sent a very nice flight attendant to pick us up at the Chicago airport and walked us to the gate. They waited for us, so we didn't miss the flight. That was amazing and outstanding customer service! We appreciate you so much!!

Reasonable fair, good service, in sum, I am very happy!

Seating was good in the economy with plenty of leg room. The seat cushions were a little firm though, especially for such a long flight. All meals were Korean as would be expected. The food was typical airline quality. Edible, but not something you would recommend to friends. Inflight entertainment was also all Korean but Korean tv and movies are made well and you can find something to watch. Just be prepared to read subtitles. Overall it was a good flight, especially for the price.

The person in front of me was rude. He may came from some communism countries and don’t care of other people. No common manner and sense between human being.

The staff were very friendly, and the flight was comfortable. That said, there was no option to specify dietary restrictions before the flight, so you may need to bring your own food. Also, there was no wifi available for the flight, though there is an in-flight entertainment console with many Korean-language shows and movies.

The legroom was great for a 5’11” person. The 11 hour direct flight had two meal services included in the ticket price which was less than other airline’s cost without food service (Canada air)from sfo to incheon. The airline is focused towards Korean nationals with the onboard entertainment selection of Korean movies but English subtitles were available. Overall premia air is a great option to fly from the US to Korea.

Plane and service were great. The entertainment is only for Koreans. Wish there were vegetarian options for food. All in all pleasantly surprised. Economy premium was quite good.

Great airline, but there was no English entertainment (movies or shows)

One of our luggage items was damaged during our flight to Newark from Incheon. Although our email communication was not responded to, when discussing the matter with the staff at the Newark checkin before our return flight to Incheon, we were provided with a free replacement luggage item. This customer service was, overall, very satisfactory.

Some favorite food ran out of service and I have to eat what was left available. Also I had to drink cold red wind! Why could not have been kept in room temperature?

Plan was very clean and very comfortable seat Very smooth flight without any engine noises.

Staff didn't seem confident about the ingredients in my lactose intolerance meal

the seat has a problem. the back had a hole.

My flight was delayed so bad i missed u it so i just said never mind

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Onboard staff was courteous, helpful, responsive and friendly. The boarding process was disorganized, poorly communicated, and disheveled. Gate agents were yelling instead of using the PA system, didn’t communicate the timing delay of our flight, and created an atmosphere of chaos rather than order and communication. As far as I know, there was no reason for their. I would hate to see how it operated under extreme conditions. I’ve never seen United Airlines operations in such a state.

The flight did not have its customary snacks during the flight. Apparently they were never loaded on the plane.

Worst service- attendants dont want to help and sat us in front of bathroom

We sat on the hot plane for ours with very conflicting messages. Some (most?) of this may be due to the flight control staff, but we were also repeatedly getting "we are leaving"/"we are not" messages. It was very uncomfortable

United Airlines changed my flight 5 hours before I arrived at the airport. This messed up my entire day that I arrived in Japan.

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

Loved and was pleasantly surprised by the food!! Request Lufthansa to help transiting passengers at Munich (confusion whether to go thru passport control or not).

Flight home was delayed multiple times, did not get home until 2am

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.

We were forced to check in our carryon and were given a green label that said to pick it up when exiting the airplane. We were told by the flight attendant to pick it up at the carrousel instead. We spent more than 40 minutes looking for the carryon which appeared at the wrong carrousel. There was no agent at the united desk for help. There was no entertainment.

Confusing with Air Canada and United flight, it was a hell, no help, rude people there, stressful environment

Great crew and the plane was very nice! The problem was that we didn’t have WiFi on both of my flights. I found that to be very disappointing today when all the other airlines always have WiFi so I could work or watch a movie.

It was my first time booking from kayak and first time with Air Canada and I must say it was cheep and flight and experience was so good. My favorite KAYAK now🥰

Overall I will say it was a very good experience. It was as comfortable as can be expected for such a long flight - 12 hours from Toronto to Tokyo. Everyone was very pleasant and polite. Even the passengers were cooperative and trying to be nice to each other. Of course the space is limited on such a long flight. The bathrooms were actually very clean. The food was very good. I liked how there was a variety of food options. The in flight entertainment system was also very impressive! There were some children on the flight but they were well behaved and hardly ever crying. Great Job Canada Air! I will definitely fly with Air Canada again!

Flight was delay for 3hours then later canceled. I missed my work. It was a bit ectic and frustrating
