    You will find comfortable sofas, benches, seats without armrests, and carpeted floors to sprawl out on in the International Terminal.

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.

Cabin Crew was excellent. They took care of everything requested. Flight was good

I didn’t know that my connecting flight from Japan to Hawaii was at a different airport - arrived in Haneda (ticket said Tokyo but didn’t notice the airport name) and had to get my bags and go out of immigration and back in to go to Narita airport 2 hours away. Such a hassle and SOOO confusing and complicated. Check your airports IN ADVANCE and NEVER book if you have to change airports. 40+ years of flying and first time had this. Never again. ANA is great but booking agencies will sell you a connection that you have a good chance of missing - even under the best circumstances.

I was charged $200 for a 2nd checked bag, which is unreasonably high and feels like price gouging. Other than that the experience was excellent.

The ROOM was great. We would love to have it on all of our flights. LOL

I would prefer to fly with Japanese airlines over American ones. They have better food and service overall

I was too late to get onto this flight. Kayak shouldn't let you book a connecting international to domestic flight when flying ANA. Your domestic flight could be in a different terminal and you won't make it because you have to go through immigration and customs.

United Airlines crew members do not know how to deal with emergency situation that caused our flight delay. For example, they should have asked the maintenance or seat belt repair personnel to come and fix the seat belt while they were looking for a volunteer to book another flight.

I always take ANA because of the great service and overall experience.

Tokyo Haneda to transport was so bad too short time . and find out way to the gate was so bad. I almost missed flight. because confused. They need more great way tell us how to get there details

Entertainment and food is best. I love to use ana for a lots japanese movies…. Food was best

Good pilot and crew. No food or beverage on this flight Entertainment is via own device thru plane's wifi.

My plans changed and I tried to cancel or change the flight for credit but was giving the run around and denied . Not great

Excellent service, excellent food and beverage options, plenty of leg room

Checking in as an international flyer is a bit tedious

I was so hungry , from Boston to Tokyo, only 2 big food .

It was okay, short flight so nothing much to comment.

The crew was nice, the food could be better, and at least 2 bathroom stalls were out of service.

The crew was attentive and provided everything I needed. The food in business class was excellent.

Good experience for economy transpacific. Reasonable comfortable seats. Food was not as good as I expected or had on other prior transpacific flights but likely attribute that to rising cost of supplies. Staff is courteous. Overall, very good.

Good the crew was nice very kind and very helpful

How can I review what was denied to me. Instead of offering to let me pay for the ticket I got booted of my flight with no way home and no choice but to purchase another ticket for 12 hours later. Filing a complaint with the DOT

From Las Vegas to Boise all went well. However, our flight was delayed in Boise and I missed my connecting flight from Seattle to Pasco. Moreover, the last flight to Pasco was full and I was booked on the 11:30 flight Sunday and given a hotel accommodation. However, I was scheduled to deliver the Sunday morning service at my church and needed to arrive no later than 10:00. Therefore, I booked a Delta flight scheduled to arrive in Pasco at 23:09. My piece of luggage checked in Las Vegas arrived in Pasco earlier today. I waited at the airport for over an hour last night to speak with an Alaska agent to no avail. I went back after church this morning in search of my piece of luggage and it could not be located. After waiting for 40 minutes to speak to the agent authorized to take my claim, he announced that he was closing the counter to assist on the flight line but not before providing me with a telephone number that would help me with filing my claim. Before I was able to make the call (due to other factors) I received a call from Alaska agent informing me that my luggage had just arrived and I am now waiting for it to be delivered. I deliberately took the more complicated route home to ensure that I would be home in plenty of time to prepare for myself for the Sunday service and accommodate my relatives’ needs. I believe the airport is undermanned given the number of flights coming in and going out. It was fiasco last night with three flights waiting for luggage and another flight landing within minutes. Today’s problems stemmed from a lack of cross training and a serious amount of cargo/baggage going out and too few people scheduled to cover.

The cabin crew was absolutely wonderful, the service was great and it was just a good flight overall.

I like them since I live in Alaska and I don't have much choice

The flight attendants were nice, but the cabin and seats were uncomfortable.

Food was terrible, noisy plane & would never pay to fly first class again. Seats in regular price are too small, no leg room & center aisle much too, too small. Seats in 1st class larger but not comfortable.

Overall, once we took off, our flight was good. Flight departure was significantly delayed due to mechanical issues. Upon arrival, it took wayyy too long to retrieve checked bags.

The ticket I purchased through Kayak did not show up in my Alaska Airlines app, and neither of the codes given to me worked for online check in. I've never had to show up to the airport at 6am wondering if I've been scammed. Cheap flight fare or whatever does not play well with airlines and I will be wary of using Kayak in the future.

Crew was rude and passive aggressive when i told them I didnt want to check my duffel bag. Then a crew member slammed my bag to the side when organizing the overhead compartment. The plane had worn leather seats with no infotainment. Plane landing was noticeably rough (this is the one year ive flown multiple times and out of american and delta this was the worst). The only redeeming quality is that we were noticeably earlier than we should have been.

The plane was delayed which was annoying. No seat back screens is a bummer. Staff if great

It was good because we traveled without luggage, carry on only.

I usually get upgraded so my experience is usually amazing. I did not get upgraded this time - which was fine - but the wifi had issues, the monitors were going in & out, & (though not Delta's fault) one of the gentlemen next to me desperately needed a shower.

The entertainment screens were not working and there was no air condition the entire flight. Very uncomfortable.

I have diamond medallion status and usually we are in comfort plus . We were in main this time ( which was fine ) and my husband wanted wine . I have at least 10 vouchers for drinks that are good for this year and next! The attendant would not take the picture of the voucher as proof and never came back to check as She asked me to pull it up on delta Wi-Fi. Instead my husband just used his Amex to buy the wine . Disappointing!!!

Food is basically Sun Chips, cookies or Cheezits. I had an exit row seat so I had plenty of room. The crew was very nice and efficient. Pilot kept us informed. Pretty good flight.

Air travel sucks. It continues to be awful for all airlines. No shame on delta alone.

It was Delta, but the flight attendants were stressful and disrespectful. I am a diamond member a travel weekly. I have not had a negative thing to share in quite some time. But this was noticeable.

Comfort Plus seat 11E seemed smaller than prior flights. The movie selection is good. Watched most of the most recent Tron movie. I'll watch the remaining part later as my movie is saved in the Delta Seatback Experience.

Flight was late from Newark to Atlanta, I asked flight attendant to please let my family of 3 out first when we landed to Atlanta because we were late for our connecting flight to Quito. She didn't and we were late for 5 minutes we couldn't board the plane and spend hours trying to get another flight with customer service for the next day.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Ineffective communication with United resulted in lost baggage. Their Baggage Tracing counter at MUC was shut down from 11:00-14:15 on my arrival. Undertrained, underinformed staff had me Running all over MUC to find someone to help me to no avail. Staff was rude, unhelpful, and unable to effectively use the systems they did have operational. They refused to contact United in any way or provide any accommodation or other resources while I waited for my luggage. This has destroyed my downstream itinerary. If they had even the slightest visibility I may have been able to reschedule/plan, but again, their staff provided nothing, and did nothing more than their website, which doesn’t even work on a standard phone browser. Miserable failure at all levels that weren’t associated with the operation of the aircraft.

Miserable. They moved my seat, but canceled the next leg of my flight. I resolved the issue at my transfer, but that resulted in lost luggage that has taken days off my schedule with no resolution. Worse, they fail to interface effectively with Lufthansa, forcing me to bounce between two equally useless help desks. The apps are unable to handle the situation, the bag dropped off the tracker, and while the call centers are polite, they do not provide written information to assist with cross-airline communication.

left on time, reasonable boarding process arrived early luggage came out quickly

I like flying first class, and United has a nice one

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

Some flight attendants were great others were cranky. Seats were very tight and sitting on an aisle was very hard as the carts and people walking constantly bumped shoulder and arm.

It was great with United overall except for two things. 1) It was a 5-hour flight and we were with kids, so we were asking for extra snacks. They were extremely reticent to dole them out even though there wasn't any meal and the kids were starting to hit their limit towards the end. 2) Baggage didn't arrive until 80 minutes after we landed.
