FAQs - booking Japan flights

  • How early should I arrive at SEA airport?

    For international flights, we recommend you arrive at the airport at least 3h before your scheduled departure time. This will allow you time to park your car, check in, get through security, explore and even eat before leaving. You can also sign up for pre-check to avoid the long lines at the security checkpoints.

  • Can I sleep at HND airport?

    You will find comfortable sofas, benches, seats without armrests, and carpeted floors to sprawl out on in the International Terminal. Alternatively, if you prefer more comfortable options, you can sleep at one of the many hotels in and around the airport. One such hotel is the First Cabin Tokyo Haneda Hotel, located on arrivals Floor 1F in Domestic Terminal 1. You can use the monorail or complimentary shuttle bus for transfers between terminals. The one-person rooms at the hotel resemble plane cabins with no en-suite washrooms.

  • At Seattle-Tacoma International Airport (SEA), you can store your bags and rent baggage carts at Smarte Carte Baggage Storage, located between carousels 12 and 13 in the baggage claim area.

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

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

Great first time experience on this airline. Very professional staff and great service.

Warm the bread. Movies: better choices to include Chinese movies options or some of the older winners of flim festival

I was able to change my flight last minute. It was more expensive, but that was my fault. Thank you for allowing me to fly!

Business class on ANA was awesome. There lie flat seats made it easier to sleep on a 12 hour flight. Food was great and service was excellent.

The crew was very nice and polite. They made sure everybody got their meal and drinks. Even the economy class had a very adequate leg room for someone that is over 6 foot tall.

Overall it was good. Making changes to the reservation on ANA’s website was little challenging. Would like to see those features improved in the future.

The flight crew was outstanding. Very cheerful and always respectful. I wish the same could be said about United. The AC wasn't the best on the plane.

The seats are uncomfortable. The flight attendants are not pleasant. They do their job, but not with a ray of sunshine and warmth. The food was awful, not what I would expect from an Asian airline. All of the other Asian airlines I have flown have far better food. The food was on par with United airlines food, which is really bad. Maybe ANA should get out of the alliance with United.

During booking, I selected the seats so that my wife and I would sit next to each other. However, the airline changed our seats at boarding so that we were seated apart. Very disappointing.

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!

We booked business class round trip from Delhi to San Diego and back. On our last leg from Bangalore to Delhi we were down graded to economy class which was big disappointment other than that everything was great.

Had an incident with a stewardess who insisted that I take a seat. I informed her that I came to use the restroom and to have some water. After using the restroom, I wanted to stretch my legs out a little cuz my knees were aching from sitting. I understood her concern for my concern and the potential turbulence (she said she knows this route and the turbulence and safety is not to be taken lightly) but I felt that her mood, tone, demeanor, and a lack of compassion for the pain in my knees were not the proper way to address a customer or anyone for that matter. This left a bitter taste in my mouth. It was her lack of professionalism that surprised me.

we have requested for hindu veg. meal during booking. but served meal was of very poor qualty and taste. they can get such meal from 5 star Indian restaurant at Vancouver/ tokyo/ Bangalore.pure hindu veg meal and no AVML

It was good but need mor amenities for toiletries and entertainment

Better screens, it would have been nice to have more comfortable seats.

2nd major delay due to maintenance issues. 1st delay missed my connecting flight.

It was great, but my bag was not loaded onto the connecting flight. I'm currently getting it resolved. If this isn't a problem, everything else was excellent.

Very clean ,flight attendants very professional,nice , Boarding was very easy

The aircraft was massive (A-380) and became crowded with 400+ passengers on board.

The plane hasnt left im stuck in seatle still my flight has been grounded for almost 5 hours

My luggage didn’t arrive with my flight. Flight was delayed by nearly 2 hours while we sat on the plane and I almost missed my connecting flight and subsequently missed the last train from the airport so it took me another 2 hours to get to my destination after arriving, Crew skipped me several times when offering beverages, and I couldn’t get their attention at times because they wouldn’t even make eye contact with me. They didn’t give me a form for disembarking so I had to go to the back of the line after waiting an eternity for immigration. Paid for on flight wi- fi that didn’t work for most of the flight.

Love flying Asiana. Been using it for over a decade now.

I had a bad experience coming from America to Thailand. On my connecting flight my check in suitcase was not put on the departing aircraft, I received my suitcase 24 hours after arriving in Bangkok and when I open my luggage my hand swelled up. The next morning when I put on an outfit from my suitcase my face swelled up and became numb. My entire vacation was ruined it seems that some kind of chemical was sprayed into suitcase and ruined my clothes and got me sick. The staff at my hotel called the airline and spoke to someone and they told me to file a complaint and gave my a website to do so. I did not file a complaint I felt like it would have fell on death ears. I had to throw away my brand new vacation clothes and suitcase and I had the worst vacation ever due to this happening to me.

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

Flight was delayed as it always is with Alaska airlines. Particularly to smaller airports. No AC on the plane so it was miserably hot.

Slow boarding and the flight crew hit me with the food cart

It was very nice flight going to Seattle and coming back to Omaha. Even got in early. Very easy to check in using the Alaska Airlines App. Thank you.

They offer the only direct flight from Seattle to Pittsburgh.

Seattle airport is a mess. New bag tag system has potential, but you need more signage to guide passengers through the process as to where to go next. Told to go in one direction and then met with a very rude agent when we did. He blamed his attitude on all the folks flying over labor day that were paying his salary. Gate area for D3 is a mess compared to the North terminal. Overall Alaska is number 1 in my book.

After we boarded there was quite a long time before we actually took off, and there were no announcements from crew about why we were delayed. Later when they did make announcements they were largely inaudible. There was no food (other than for purchase) on the flight and no entertainment. Thats not a complaint, just explaining my ratings in those categories. The flight was smooth. Baggage claim was rapid.

The airline staff was great! The best safety review ive ever had!

Agent boarding us in San Diego lectured me on showing up on time for the flight, and said that if I had been three minutes later, he would have denied myself and my wife boarding. Our trusted traveler numbers were not in the system, even though I entered them when I bought the tickets. Our food orders were not in the system, even though I entered them prior to the flight. My wife requires a wheelchair, and that was delayed on both flights.

Why was I charged for a glass of wine on one flight and not on another? Why no movie or TVs? It was a long flight.

I liked that it didn't take 10 hours to drive here. Super short trip!

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

The food was terrible especially for a 15 hour international flight. The crew was unpleasant as well.

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Quick check in. Everything went smooth. I don't know what can be done about airline food.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

Delta made it easy, comfortable and timely. The crew was fantastic.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Nothing special. The crew never went out of their way for anything.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate
