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.

  • Where can I find the baby care rooms at HND?

    There are multiple baby care rooms in all the terminals at HND with baby chairs, hot water dispensers, washbasins, and private nursing booths. In Terminal 1, there are 6 nurseries in the arrivals lobby and 9 in the departures lobby. In Terminal 2, there are 7 nurseries in the arrivals lobby and 9 in the departures lobby, among many others throughout the airport, which are very easy to locate. The restrooms also have to change tables and small urinals for young boys. You can also rent a stroller from any information counter.

Top tips for finding cheap flights to Japan

  • Morning departure is around 20% more expensive than an evening flight, on average*.
  • 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. Rented baggage carts cannot be taken through security to the other side, so you have to rent another on either side.
  • There is an Art Walk from Starbucks in the central terminal to gate A14 at SEA, where you can admire the vast collection of glass, paintings, sculptures, and sound artworks. There are also live music performances throughout the airport that you can stop at.

The space for the seats i like it. Its not too close like other air line. The food is ok and also the staff. I'm waiting for my flight rewards point because until now i didn't recieved it.

The staff, ground and air, at ANA was very helpful and friendly during check in, boarding and during the flight. This is the reason why I always fly ANA whenever I go to Manila. The food was not the best but the flight crew more than makes up for the shortfall.

First I will say this was really NOT an ANA flight. ANA used a UNITED jet to perform this flight. I specifically booked with ANA because I did NOT WANT TO FLY UNITED FOR INTERNATIONAL FLIGHTS. So to spend $1800.00 and then discover after booking that it was going to be handled by United was very disappointing. I will be more careful next time when I book. The interior was very cramped in economy class; the dinner meal was terrible and also had extremely small portions for an international flight - the bread roll was ice cold and stale - that salad was very wilted; I’ve never had a “snack” that was so salty that it was difficult to eat; the breakfast “waffle” was practically unrecognizable. Really horrible meals for a very expensive international flight. Bathroom floor was also pretty dirty. I’m hoping my return flight is a real ANA airplane that is cleaned and serviced by ANA personnel with ANA meals. I will never book with ANA again if they continue to use UNITED airline jets. Yuck!!!🤢

Ticket was purchased as a United Airlines flight (operated by All Nippon) like what does that even mean? Makes for a VERY confusing flight experience. For instance, what do I look for a United drop off signage and ticket counter or ANA? No explanation anywhere to be found. I also felt a little bit scammed by the obsurdely restrictive seat selection provided. Only middle seats available!! Are you kidding me!! On 6hr + 10hr flights you're forcing me into the middle seat without telling me before I purchased the ticket?? This should be illegal. And to top it off, on the Tokyo LA leg there were quite a few empty seats including window seats! I must also say, the food was a dissappointing as well for my taste, fish with rice ( mostly plain white rice) or a vegetable medly for the breakfast meal? Should be at least 4 choices and at least 1 with eggs. Outside of these issues flight was otherwise ok.

Ground and flight crew were all courteous, extremely helpful and professional. Overall, process is really organized, from boarding to disembarkation.

This is a very long flight and the first time I have flown on a Japanese airline. I was very impressed with the staff. They worked hard and offered food and drink regularly. Plane was very well cared for. The let room was good . Food was ok but better than other airlines.

It was very nice. I was a bit disappointed by the few meal services. There were probably more drink services that I missed while sleeping, but I would have liked the crew to bring more than one drink service before landing and to bring more than one drink service and coffee service after take off

The space and bed was very comfortable , flight attendants very nice. The food was not tasty at all. I ordered the rib eye and it was so tough I couldn’t cut it.

I wish the serve should leach and drink. Maybe because only 2hr

Seat was roomy enough . The Asian selection for a meal was good . The tortellini was not very good. Service was excellent. O

The food was not that good. I liked the miso, green tea, and ice cream. I wasn’t able to put my carry on bag under the seat in front of me. The flight was smooth. Please expand your choices of movies especially the new ones. I can’t choose any of those films. They’re old.

I like the braised beef., miso soup,, and green tea. Very little choices of hollywood movies. The PA announcement in English was not very clear and very soft. I could hardly hear.

More updated movies & Chinese movies. The food sometimes overcooked. Prefer to have more neat snacks in between than just choose from the menu. Please change the menu every now and then. This is my second time flying within one year and the menu didn’t change at all!

Food is lagging. Very poor choice. Like vending machine fast food.

Please change the menu more often. The beef is not tender, more choice in ice cream flavor. Dessert is not good too.

The Experience was fantastic, it's a quick flight so no entertainment or food. Just a refreshment

Great crew, Japanese domestic flight is just a drink service but crew are very attentive

Again I paid for an upgrade on my credit card didn’t get it need a refund. . American I not good at gettin in contact for refunds.

l enjoyed the variety of good and drink choices. The flight attendants were very quick and efficient to our needs.

-Bathrooms were regularly checked/maintained. -Food was okay, but the miso soup was good. -Top of my foot got bitten by a bug when I took off my shoes and was only wearing my socks. It was swollen and very itchy for several days.

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Had a broken tray in business class. Crew just shrugged it off.

Everything was great except for the seat. The backrest would not stay in the upright position.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Mi primera conexión se retrasó por lo cual perdí mi segunda conexión la cual salió adelantada

Crew was not friendly when I went to request a seat change.

There were choices for the snacks. Good choices and tasty lunch and breakfast as well.

The flight crew was amazing. I’m very tall and they moved me to an exit row unsolicited!!! Amazing service.

Very smooth flight, great landing- entertainment didn’t work so well

Pilot and first officer did really an amazing job. I can best discribe their flying as finesse. Inital service with food/beverages was great, however after that the crew just kind of packed it in and were sitting in the galleys chatting for the remainder of the flight. I wanted a bottle of water, went to the mid plane galley, was told they were only available in the back, so had to walk the length of the plane just to get a bottle of water. That was a new experience on an airplane for me. Pretty sure evem Spirit will bring you the bottle of water you are paying for. Seat was comfy, magazine worth the read. Entertainment nonexistant unless you want to pop for the $4 headphones.

When I got into Maui I had a layover but there was a flight to Honolulu earlier. I asked the gate agent to see if I could get on the earlier flight to get home sooner. Ke'van is so great! He was very helpful and friendly and I appreciate him very much

Unable to perform online check in using Hawaiian Airlines APP Only ONE meal choice available - Totally unacceptable Low Airline ranking compared to other International airlines and service Old Airplane (A330-200) Entertainment system - Outdated Total Score - Mediocre

This flight was delayed approximately 4 hours due to bad weather in HNL.

It was great with the exception of a rude desk member on the way back. And a terrible sandwich on the way back.

One of the best flights Ive had in a long time

Flight delayed then cancelled then gate changed two times then baggage lost.

My flight was canceled minutes before boarding started. It took three hours to get rebooked and it was on another airline overnight with another stop added. All I got was two $15 food coupons.

The plane is extremely loud and there’s no place to charge devices.

Squeeze like sardines. ANA has much better leg room. The food on air canada was disgusting. Worse that left over microwave dinner. Like you heated up microwave dinner then saved it overnight, then microwaved it again and added nasty garnish to try to elevate but instead made it as edible as cat food.

They canceled the flight on us very close to the flight date .

It took 66 hours to get from Seattle to Tel Aviv. As a minor, I was left for more than 12 hours in Toronto and Frankfurt without hotel and food vouchers. It took 5 layovers. It was insane and not okay

It was delayed but got us to YYZ. I had great copassengers.

Flew SEA-CA, then CA-NRT. First flight was short but very uncomfortable, dirty, and had very small overhead storage space. The seats and fans were not cleaned and had visible dirt on them. Second flight was perfect.

My second flight ended up being through United and it was fine. Again, just frustrating that it was so late.

My experience was pretty frustrating because the first leg of my flight on United (though booked through Air Canada) was delayed causing me to miss my connecting flight on Air Canada. This could have been an easy solve as there was a direct flight later that morning via Air Canada that they easily could have put me on which would have only gotten me to my destination 2 1/2 hours later but because United and Air Canada don’t seem to have good communication they gave me the run around both telling me to talk with the other which I did three times to no avail. I ended up taking the delayed flight and getting on a new connecting flight which ended up getting me to my destination 6 hours later and I missed the event I was planning to go to this evening.

Everything went smoothly and as expected. We were on time and one flight arrived early.

First time flying Air Canada and the trip was very pleasant! They did a great job getting us out of Toronto and into Rome (early!) For an international flight it was very enjoyable.

This is not a Business Class equipped airplane and even the crew apologize before take over BUT BUT Air Canada charged full business class fare
