Service and the plane itself were terrific, but the extensive delays both before we left and after were a real pain.

Service and the plane itself were terrific, but the extensive delays both before we left and after were a real pain.

It was good and there is nothing to complain about .

The seats were narrower compare to other airlines traveling to Asia, which makes them uncomfortable after 6 hours The plane was worn, my tray table wasn’t level, You had to pay for WiFi and no Bluetooth option to use your own headphones. The crew was excellent in servicing the food and drinks. However I felt they needed some extra hands to serve the two sections of economy at the same time. They run out of one of the food option as they got to the rear section of the plane. Having travel on other Asian airlines during this trip; American Airlines can learn a bit from them, but I wonder if their service is geared towards a clientele that has become accustomed to not expect to much from an airline.

It was just a short flight. The crew was nice. No major issue.

Overall, it was ok. The attendants are nice. It was a short flight, and I did not use the restrooms. What I was frustrated was the check-in. I was to fly from ATL to Chicago (American) then change to Japan Airline to go to Japan. I checked in, but I only got a boarding pass for the flight from Atlanta to Chicago. It said I would need to check in for a flight to Japan on Japan Airline site. When I tried to check in on JAL website, it said I need to check in American... It was very confusing.

The crew was great, food was good. My concern is about the plane itself. It wasn't super clean, and during the landing process (after attendants had to take their seats) the air conditioning vent above my daughter's head started leaking a lot of water. It leaked for about 30 minutes, until we landed. I let the attendant know about the leak as we were getting off the plane, and she was very kind about saying she'd look into it. Given concerns about hygiene on planes, plus the fact that my daughter had to hold the blanket over her for 30 minutes to avoid getting soaked, that was not a great situation.

Absolutely WORST experience I’ve ever hard NEVER buy your airline ticket through a third party website, especially this one. Basically stole $1300 from me and has the WORST policy taking a WEEK to change a name on the reservation? A complete joke of a company.

There was a problem with the maintenance so missed the flight from las vegas to L.A and then L.A to Narita with japan airlines. They took care of the problem by rebooked with cathay pacific airways.

I paid for premium and it’s wasn’t what I was told I would be getting. Food wasn’t good. Should be able to pick and not be served items you dislike. Very little leg room.

I am trying to select a seat during booking but it respond that set assigment will be given during check in, and the seat assignment they give is in the middle seat and 2 row from the rest rooms, i am the person who pee a lot in this case I disturb so much the person beside me ,this trip is from Haneda to Texas, the trip from Texas to Cvg is a much better because its a smaller plane few passenger

Fast and efficient flight. Wifi worked well. Food selection could have been better

Never book through Kayak. They can offload booking to third parties that are completely horrible.

Crew is excellent Wifi needs to be improved in order to connect to the internet.

The flight arrived on time. 2×2 seating meant no one needed to sit in the middle. This was a connectibf flight from Singapore and required going to 3 counters in different levels to check a golf bag

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.

It was ok, but not what it was like 20 years ago

We had a cancellation due to weather, but the American Airlines staff was very helpful. Once we got on a plane, the trip was great.

Great food and good entertainment options for the long flight.

It seems that qantas are trying hard to regain their status as Australia's premier airline. I only flew economy but happy with the service entertainment, food, configuration everything.

I never flew with alliance. Kayak is a joke and none of the flights or times were correct. Won’t ever use kayak again

I missed my flight due to unforeseen circumstances It was, however , an excellent price !

Loved the food and beverages available, spacious economy class, excellent entertainment

Very good overall. Highly recommend for all flying to Australia

Helpful staff when I felt unwell. Qantas need to have an audio/music channel so you can listen to various music/.artists

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.
