Airline reviews
Pros: "Return flight from Singapore to DC via Tokyo was more pleasant. The stewardesses were more service oriented."
Pros: "Return flight from Singapore to DC via Tokyo was more pleasant. The stewardesses were more service oriented."
Pros: "The 787-900 used is a great aircraft from passenger comfort and the overhead bins can take all your carryon bags."
Cons: "Our flight used a remote gate - so we had take a bus to the plane... therefore had to drag our carryon up and into the bus... then up the staircase into the aircraft.. it also made us :30 late departing"
Pros: "The crew were attentive yet not invasive and spoke excellent English"
Cons: "I wish ANA few to Denver!"

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.

Food was high quality. Crew was extremely professional, polite, attentive. Flights were on time. Plane had good media tech.

It was ok I thought because my flight was 1pm i was expecting to have lunch but it didn’t and after 7 hr finally dinner time was only chicken sandwich and next breakfast was an hour before plane land in Tokyo. so I should bring some food with me. Japanese flight attend was nice but the other was chewing gum and how she ask and respond to customers was not professional I felt. Maybe because Japan flight attendant is highly train and everyone looked very dress and professional so I was kind disappointed. I like that the bathroom was very clean .

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

Lovely airport at Haneda. Great food selection. Spacious and private boarding area with dedicated bathroom for each gate.

They did not get my request for veg food that i made a month ago. Also did not have any backup veg food on board or fruit plate or simething. Very disappointing as i had hward about how grwat ANA was supossed to be. Alsio entertainment was lacking and screen and tech was subpar. Overall just mid to low tie. They are living off reputation and are being passed up by most other carriers.

Ana is absolute world class They should not work with united

Japan and China airlines were incredible. On board service was impeccable. All the flight attendants were helpful, friendly, and always smiling. Airplanes were very clean. The boarding crew was extremely accommodating and very nice as well. Overall I was extremely impressed.

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

I slept during flight so didn’t eat at all. Very kind flight attendants.

This flight was operated by American Airlines. AA was completely unprepared for the crowds at DFW for Spring Break and were ridiculously understaffed. They had only three operating kiosks for self check-in, and ONE agent to handle hundreds (thousands?) of dropped off bags. She also had to do double duty to assist passengers at the kiosks. In comparison, flying on United Airlines at Christmastime was a much smoother experience.

It was one of the best experiences. The staff were amazing. JAL is my second favorite Asian Carrier I have flown on. Korean Air was my first. Thank you JAL for bringing me home safely and for such an amazing staff and service.

JAL is quite nice in business class. Comfortable, spacious seats. Their entertainment, especially their film selection, isn’t that great though as their are not many new releases like some airlines offer their first and business class customers. . Food is excellent and the option to order on demand is always quite nice, which JAL offers. Flight attendants were very friendly and kind. Overall very good experience with JAL.

Very comfortable unlike my first trip where they switched my flight from JAL to AA which was a disaster!

I requested a vegetarian meal, and somehow that wasn’t processed from Japan airlines to the new carrier American Airlines when it was on the ticket. Don’t know if that was KAYAK or Japan air or American Airlines. But the crew scrounge together something for me and that was very good. Also I think American has the tiniest seats in the industry. It’s kind of annoying but it got me from .8 point B and now I’m at point B on the final point at LAX. I had to leave the airport and then go back through security to catch my next plane. I’ve never had to do that before. It was very annoying.

I was not given any food boats the times the entire flight. I had to go hungry for 10 hours the first flight and 12 hours the second one. They said they did not receive my special request for a vegetarian meal and they were very rude about it. I’m vegetarian because of religious reasons. I will never fly Japanese airlines ever again. And I really hope you are able to give me some compensation for this issue that was cars to me since you were also a Party to this whole transaction.

serving nuts is great, but it would be even better if it was overnight roasted nuts.

The best way to travel a long intercontinental flight. Staff are kind, polite and welcoming. Passengers experience a comfortable low stress environment, Customers feel they are well cared for by a highly trained and professional staff. I will shout from the rooftops when I get back home, "Japan Air is the way to go!"

Pros: "The seats were comfortable, the plane was empty so could move for comfort"
Cons: "The food was not very good, the airplane was empty, but assigned seats to fill rows while spouting nonsense about social distancing"
Pros: "The flight attendants are the most professional and attentive employees I've ever had the pleasure to be served by."
Cons: "The movie selection could have been much better for such a long flight."

When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

A pc of cake or biscuit at least. The airport was like a maze need to take another bus to the main terminal to immigration.

Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline

They were able to assist my elderly father and myself after not being able to check in to scoot. The counter service was phenomenal. They did what they could to get us on the next plane so we could catch our Connecting flight. Scoot closed early on us so we ended up missing our flight.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

Transfer within the same terminal and lots of facilities at the airport.

The seat comfort, the food and of course the crew, they made you feel welcome and relaxed 😊

Due to the delay of my first flight, my connecting flight with JetBlue was canceled by Singapore Airlines, but the JetBlue crew was very accommodating and rebooked a seat for me. The crew was very nice and had good attitude.

The overall operation needs to be improved. The in-flight services took forever and sometimes ran out of options.

Crew is way too many times on the intercom re explaining the same thing

Amazing comfortable chairs great snacks super friendly staff pilots did excellent job. Smooth sailing all the way. Definitely be flying United more.

We waited too long to get water while the plane was on the Tarmac awaiting de-icing.

Excellent as always. Had issues checking-in online. Please fix.

The plane was delayed coming in and on the tarmac. I was coming from another flight so it made for a very long day. The stewardess kept trying to slam the overhead bins closed and I was worried that she had damaged my new luggage. They ran out of snacks and lccdsddd me a hummus box which was nice. It took them a very long time to pick up the garbage so I could not go to the washroom and had little time. To prepare for disbarment. The TV system was hard to control from the armrest and picture wasn’t clear. The crew did apologize several times for the lateness. It took the Denver airport an unusually long time to de-ice the plane.

By in large it was a good experience. The flight crew was great and that's the most important to me. Boarding was fine.

It was fine. Everything ran on time, crew was great.

Staff friendly and app worked really well. Modest delays were frustrating

They rerouted flight to LAX. Offered nothing but a 5 hr drive to SBP. No compensation. No regards to our healthy and safety.

Both flights were fine. I wish there was a little more legroom, but we got to where we needed to be on time, the crew did their job, and that’s really all that matters. We’ll fly United again.
