  • Flying on Sunday is usually the cheapest. Flights on Saturday cost about 15% more on average, so being flexible with your travel dates could help you save.
  • If arriving on time matters more than price, consider flying with one of the most punctual airlines on this route: ANA, Japan Airlines, Delta, Alaska Airlines and Hawaiian Airlines.
  • If you're looking to save, Aomori (AOJ) is the cheapest airport to fly into from Seattle. If you have onward travel, don't forget to factor in the cost of your journey by train, bus or domestic flight.
  • Start your trip in Tokyo, which is the most popular destination in Japan. From there, it's easy to continue on to other popular destinations such as Osaka, Kyoto and Sapporo.
  • If you want the shortest trip, choose the Seattle to Japan nonstop route. If you'd rather save money, the route via Honolulu (HNL) is usually the cheapest.
  • 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.

SAN-NRT was excellent experience with crew helping and assisting in all aspects of comfort. But NRT-BAN was not that comfortable with no blankets and pillows provided and treating it more like premier economy class. This has been the pattern I have observed where JAL uses non-trained crew, uncomfortable seats, restrooms not working, locking up window seats, business class comforts taken away on NRT-BAN route. Overall quality of service goes downhill on NRT-BAN flight. Not sure why?

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

Since I traveled on my birthday, they gave me a gift and a card. How thoughtful and caring.

JOKE of a company with the most Ridiculous policies. JAL is amazing, KAYAK/UNDERPRICER is the worst company I have ever dealt with, NEVER AGAIN

No food at all so it was a bit of a culture shock for international travellers with connecting domestic flights.

Excellent! So happy that the crew members were so helpful and friendly and able to understandably communicate. They’re very receptive with someone like me, with disability. I love that I did not even have to ask for luggage help like, having to place and take down my carry-on luggage in and out of the over-head compartment. Hope, help is extended to disabled passenger(s) through out class classifications they’ve bought; economy or business class it might be. As a disabled person myself, I’m truly of great appreciation of this kind of help. Means a lot !!! Thank you so very much JAL crew. You out done others on this customer service part of the trip. Please continue to do so. From now on, I’ll choose JAL as my airline whenever I have to fly to any southeast asian countries. And I will disseminate my excellent travel experience with you to others.

put me in front row, screen was tiny, movie slection wasnt very good will be flying back on another airlines

It was good but need mor amenities for toiletries and entertainment

First experience with JAL so was okay to pretty good. 10 hour flight in premium select seat. . Seats in that category should be better than pretty good. Seat pan a little short for tall people but plenty of leg room; I think JAL in process of new planes? Also, — they could have offered a bit more water throughout flight and meals not the greatest. That said, certainly 200 percent better than a very recent AK Air International flight in similar cabin class in comfort and meals.

Need new movies, a lots of them are 20-10 years old or older. It us a very long flight we need good entertainment. Please load more new movies!

All was great on flight to Tokyo. The ROOM setup was very comfortable. Definitely will try to do again.

I thought I purchased premium economy but got an economy seating for an expensive airfare from Kayak. Not able to pay extra to upgrade at all

On time, food was great. Didn’t wake me up when they saw me sleeping and as soon as I used the toilet, they came up and asked me if I wanted dinner. Right on!

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.

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

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

The staff is amazing, I cannot stress that enough! The food is really good and snacks at stations to take for yourselves. Economy seating is fine, not the most comfortable, but our friends in Premium Economy said they were very comfortable! Decent entertainment options, but being built in, you have to use their cheap headsets unless you have your own plug in ones. I only have Bluetooth earbuds.

Great service, wonderful meals, excellent entertainment, clean bathrooms, top notch experience

It was very good. Lots of room with superior food and service. I will not hesitate to fly ANA in the future!

I chose my seat for the window: there wasn’t a window in my row. The charging function for my device didn’t work.

As a deaf person I appreciate the assistance provided by the boarding staff and the flight attendants.

WiFi did not work for the flight. Crew were polite but kept asking me to move my bag even after it had been moved to the preferred position previously and not moved since. I had a winter jacket as well and they changed their minds multiple times about where I was allowed to keep it.

Good seating and leg room. Able to choose seat. Nice crew, polite and helpful. Nice snacks. Meals have to be pre ordered, short flight do no meal required.

No complaints. Nothing for entertainment, but it's a regional smaller body aircraft, not a longer range long body. Didn't partake in any snacks, mainly slept for the whole short flight. Got me to A to B as intended.

I reserved exit row as I am 6’7” and was very disappointed to find out that my seats were as crammed together as the rest of the plane. Worse actually, as the seats don’t recline. I believe I paid an additional $200 apiece. What do I get for that? I guess it’s on me that I didn’t do the research to know this in advance but I’m tired of buying airfare which used to include an actual seat on the plane and now it is an additional charge. I think the seats I purchased are sold at a premium by deception by people like me that think these are desirable. Got forbid there’s an incident and passengers have to escape through these tiny passages. Love to travel but have to reconsider future trips because of the dishonesty of your industry. Have always had good experience in the past with Alaska but now I have soured. Thank you very little, Dean Jones.

Everything was fine, flight was on time. Seats are pretty comfortable. I paid extra for the extra leg room. Did not get food. The only thing I wish Alaska had was a seat back screen rather than trying to watch things on my phone.

The flight attendants stood there talking to each other instead of welcoming people on the flight.

My bag was gate checked in Seattle and I was told it would be at the end of the walkway when I arrived in Idaho. It was not and I had to get it from baggage claim. Southwest Airlines will gate check a bag even if they have room for it in the cabin. I like that a lot. Seattle Airport is not that easy to maneuver. Indianapolis is one of the easiest airports to navigate.

Truly, everything was professional, and extremely friendly with lots of smiles from all the staff. My only complaint is that both coming and going from San Francisco to Seattle and back the public announcement system on the airplane when I was sitting in the exit row was so loud that it hurt my ears, and I was not the only one I did report it to one of the stewardesses who thanked me and apologized, but truly Alaska Airlines is my favorite domestic Airlines by a far shot

Cheeseburger was good, but other sides were awful. Attendents were great! Flight was good, except for changing gates 4 times and flight being delayed over an hour..

dropped my bags at Seattle Delta curbside. 1.5 hours before departure. one bag oversized made it. the other was left at curb and mishandled. poor communication from delta in sjc baggage claim. No internet on flight and food choices in business are horrible. You are forcing us to fly Alaska which is shockingly better than the Delta experience. that is a low bar.

Delta is the best. It was all very easy and on time.

Delay from Atlanta to Tampa was simply unacceptable. Multiple delays led to us landing after 3am. Worst travel experience of my life

I somehow thought my food preferences was saved to my account— everything had dairy and couldn’t eat anything.

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

The flight was done by SkyWest only WIFI no entertainment center are available on the CRJ

Everything worked smoothly, never had a concern with the flight from start to finish.

My flight was delayed by 4 hours in 30 minute increments. The gate agents were amazing but the communication was not. We were told that there was a maintenance issue but they didn't know what it was. That didn't inspire confidence. Then they said they found it and it was fixed and the pilot just needed to sign off. Then the pilot needed to talk to the other pilot from the arriving flight and we'd be fine. Then we were waiting for the pilot to call back. Then the maintenance issue wasn't fixed. Then they decided we were getting a new plane (why didn't they decide this earlier??). Fine. But then they announced we were changing gates AND terminals. And we were boarding in 20 minutes. So we all had to run to the new terminal gate. We could have taken off at that time, but we then had to wait for all the people who rebooked on a different flight to book this flight again. That took 30+ minutes because there was only one gate agent. When everyone ditched this flight, I saw it as an opportunity to upgrade to comfort. Delta, the greedy jerks they are, charged me $121. After their delay, their fault, their issues, couldn't even discount an upgrade. They only handed out $12 meal vouchers for the delay. I can't even get a snack from starbucks for that.

Love me some Delta. One of the few airlines to recognize and support veterans. Easy boarding, flight was on time and arrived early and the flight attendants were excellent on this flight.

We sat on the runway for over an hour before departure. That was unwelcome.

Premium economy was worth it. Great seats and good food.

Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

Very comfortable seating and the Flight staff were very attentive. The premium economy section that I was seated in was very clean, updated, and well appointed. I would highly recommend flying United Airlines as this experience was better than the Japan Airlines business class that I flew several months ago.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

We fly to Ecuador frequently. Checking in is usually a hassle because most United agents take some time before they can verify that my passport doesn't require a visa to Ecuador. This time the process was even longer due to the cyber attack. But she was really nice to us. So glad we brought plenty of snacks to supplement the 3 flights from SEA to GYE.
