Staff was rude and loud. No respect for customers unlike the Starflyer Osaka to Haneda sector where service was outstanding. What a stark difference. Maybe United should learn from ANA how to do customer service.

Staff was rude and loud. No respect for customers unlike the Starflyer Osaka to Haneda sector where service was outstanding. What a stark difference. Maybe United should learn from ANA how to do customer service.

The meals were sufficient and tasty considering it was air travel food. Water coffee and juices offered each time a meal came by and water distributed between meals. It was good service in my opinion. Plenty of movies to enjoy. May not be the one you want but plenty of older movies and plenty of current ones as well. I enjoyed the trip.

we were in premium economy, but we both got middle seats and had to sit separately. i could have avoided this by trying to obtain seats sooner, but i tried 3 times and gave up. ANA's technology is not friendly for newcomers. no, check that---I think it is nigh impossible. not sure we are coming back. ana can do better to provide a front end that's friendly to users in both US and Japan.

Checking in via an alliance partner, even a foreign one should get TSA Precheck printed on your boarding pass. The paper copy issued by ANA didn’t show it. I couldn’t get my digital copy due to some technical issue arising because I checked in with ANA. The kiosks at SFO similarly threw an error. The only way I could have gotten a new copy of my boarding pass was from the UA counter and lines were nearly as long as TSA so I bit the bullet and went through the regular TSA line. If UA wants my business, they need to improve that process.

Great as can be expected with a 10 hour flight over the Pacific. Great movie selection of new releases that hadn’t hit streaming yet. And despite the bad rep, I actually like the airplane good.

One of the best business class seats I’ve had. The lie flat seats made it comfortable to endure a 12 hour flight. Service was excellent and food was great.

Almost 6 hours of delay with over 12 gate changes. Flight was supposed to depart around 6 and instead depart after 12am. No accommodations were offered than some snacks closer to midnight when the crew was planning to throw away some snacks.

Purchased WiFi was slow to non functional. Staff was not personable or friendly. Seats were cramped. Boarding took long but I expected that.

The crew was excellent. The flight was delayed for 20 to 25 minutes. We did arrive a bit later than expected. The AC could have been better.

Very disappointed with the seat selection. During the booking, I selected seats such that my wife and I would sit next to each other. However, during check-in, we found out that the airline changed our seats and we were seated apart; and I was stuck in the middle seat with two strangers. Very disappointing experience. We would not fly ANA next time.

Check in procedure is harder than with other airlines, infotainment system is outdated

I liked- timely took the take off I disliked- food for ANML was not served even after request, ASVML was really bad, the cleanliness of seats were not up to satisfactory level and I had to use my own sanitizer. Even basic sanitizer packs were not served, cabin crew could be more friendly as I noticed their behavior against other fellow passangers who were not speaking English well.

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

Fantastic flight company. A higher standard than any American airline company for sure.

great experience - staff were kind and attentive and food was excellent. very comfortable flight that felt much shorter than 14 hours.

I thought this was a JAL flight but landed up being a code sharing one with Hawaiian Air. Got upgraded by check in staff and they confirmed my bag coming from Bangkok which was great. Cabin crew was solid, not especially friendly, just super efficient and wanting to get the job done which they did. Very fast and agenda oriented. Worst part is my economy plus seat was no better than my economy seat on JAL. Plus JAL has way better food, cleaner plane, and better crew. Worst part is when I landed, was never told where to grab bags. I had correct flight name and number for JAL but there was a Hawaiian flight number in another baggage terminal. I wasted over an hour with no help from ground staff for my bag. Hawaiian and Alaska airlines merger can’t happen fast enough as Hawaiian airlines is a dinosaur. Bad experience again and I’m not surprised. JAL rocks!

The seat was uncomfortable and seemed to be on its last days. Loose and sloppy

Business class lie flat seat is the best and easiest to operate 👍👍

My seat had zero leg room. I thought I was flying Japan Airlines, a company I picked based solely on the legroom... When I got to the airport on my first flight, they informed me that I was in fact flying J.A.L VIA American Airlines... What a bait and switch. I will never fly AA on an international flight ever again.

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

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

The staff on the plane were attentive and friendly. The frustration with the cabin crew was that we were served second to special diet people. And, we were in economy section. The boarding staff was mediocre. Got scolded for requesting to sit with spouse on 14 hours long flight home. Was told they cannot break up families for us. Didn’t understand how we were denied sitting together as we are husband and wife. After many words of exchange, we were accommodated. Cleaning crew did a horrible job! Bathrooms were unsanitary or dirty from beginning of flight! Didn’t expect sparkling as its economy, but did except decent.

Headwind delayed our flight which wasn’t the airlines fault

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

Food could have been better. Too many passengers getting up and down all the time.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

It was very good experience on board to Sydney with SQ.

It was an average flight. I would have expected more from this airline. Food, seats, service, etc was just average. I just give them some extra points for offering free WiFi on board with just a Krisflyer account.

Flight was canceled. I was not alerted. It was only kayak that alerted me

Flight was 2.5 hours late leaving. We spent 50 minutes of that sitting on the plane with no explanation. They did reduce the time in the air so we arrived a little less late which was something. The cheese and crackers were okay but the wine was terrible.

Excellent as always, I won't fly to Australia, and back to the US on any other airline. The flight crew is always top notch, and have a way to make one feel extra special. Thank you for your service, I would rate Qantas Airways a 10+.

Basic airline, aircraft and service. AA gets you from point A to B. My flight was delayed by 2 hours too.

No internet on flight, which makes log travels really hard.

Not great. The inflight entertainment was all on an app, and I did not want to watch a film on my phone. Also, the range of options of films was limited.

My flight from Dallas to Sydney was cancelled. My entire trip was rerouted to include the following: Hartford to Washington DC Washington DC to JFK JFK to Auckland Auckland to Christchurch I paid for an aisle seat on the flight to Auckland and was asked if I would take a window seat to accommodate a family. The agent at the podium failed to mention that the family had a 3 month old baby and that a bassinet would be used during the 16 hour flight. The only way I could get out of my seat was to crawl under the bassinet of the sleeping baby. I think it is wrong that I was no given the choice to sit in another seat, that the agent knew what she was doing and chose to not properly disclose my seating arrangement. Terrible treatment.

they ran out of fruit for breakfast and so I just had a yogurt instead. other than that the flight was good

by the time they got to our row, they were out of some of the food options. games and movies were great but maybe more game options like tetris or pac man would be great

A few more inches of legroom is all i ask
