Great service but food taste and options have gone down a few notches.

This airlines is always my favorite. Very consistent customer service and food is good. My last flight with them, I had no idea we landed because it was just that smooth of a land.

Excellent crew, immediate attention for any request. Both ways on time (rather before time arrival at Haneda). Only complaint was that the seats are not reclining like rest of the airlines that I travelled. The Backrest is fixed. The reclining is only within the box seat, so you slide down forward for reclining, not backward. So it was bit uncomfortable. The food for the day trip was excellent. For the night flight, no breakfast was served, only dinner, which was disappointing.

At least it was not very cold inside the plane. I noticed there was now a bidet in the bathroom and that’s good! I didn’t like the window seat. Flight was smooth except for 1 turbulence. Plane was on time. Thanks. Food was not that great. Miso and green tea were good! As usual movies were old and there were no changes.

Food as always. PA was not clear, especially the English ones. Very limited Hollywood movies. Unlike the first flight I had, this plane has less leg room and less room for my under seat baggage.

Please change menu every now & then bc I fly twice within the year and serving the food the same

The Experience was fantastic, it's a quick flight so no entertainment or food. Just a refreshment

Great crew, Japanese domestic flight is just a drink service but crew are very attentive

First of all I had dozed off. And when I woke up, my food was on a tray without telling me the food was there or asking me if I wanted something to drink. They never came back to ask me if I wanted anything to drink and I tried to stop them several times. I personally have a problem swallowing food without something to drink with it. so therefore I could not eat., second thing for the entertainment. There was no place to plug the headset in because the tip had been broken off into the monitor to where you couldn’t even watch a movie or hear any music that was annoying .

I didn’t like the check in process I had to check in at the counter took too much time . Didn’t give the upgrade my seat .

The overall flight went well and the aircrew was pleasant.

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

The aircraft was slightly newer but the food was very bad. Bland and uninteresting. Nothing special at all.

I felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

Everything went smooth. All flights were on time No changing gates, . No changing flights . It was like a completely different airlines tha n the last time I used Cathay Pacific . The last flight, 2 months ago, I had before this one was from Philippines also . I got changed in Manila and was told it only added 2 hours onto my flight . My 20 hour return trip ended up being 30 hours return with a 10.0 hour layover in New York with no seats anywhere . Everyone was sleeping or sitting on the floor . Unlike the hotel I was given in Manila to wait for this flight home . I never thought I would use Cathay Pacific again . But I did and this time you were great! I should have complained about the flight and layover from Hell a couple months ago. Consider that I am complaining about that august/23 flight now . Thank you got the great flying experience on my way home from philippines .

In flight entertainment system including wifi were down and passengers got tortured for the 16 hours flight without any of these. Food was spoiled as well for the first meal provided but second meal was Ok. Overall a horrible experience which was not at all expected for such a long haul flight which was expected to be THE most memorable part of my planned trip for family.

I traveled to Singapore for 5 days, I didn’t receive my luggage until the 3rd day. When I received my luggage was broken which they fixed it supposedly. I never had such a poor experience with the any other airline. I honestly think it should be a compensation for all of my losses and suffering that I went through.

I booked this through Travelgenio and requested a cancellation due to COVID related impact. Their customer service was absolutely terrible and they informed me after the flight had departed that they could not cancel my ticket. Worst experience, will never use them again. Strongly reconsidering using Kayak in future given how poor the travelgenio experience has been.

Cons: "The flight delay could have been announced over the speakers"

More facilities to transport to the gates......felt too much walking distance

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

It was good no problems made it on time for the next flight overseas!

It was a really long flight from Doha to Philadelphia and it was overall a good one. The one area that I would comment on is that there is a lot of single-use plastic and disposables in the meal service for American Airlines. It would be great to see more circular options in the meal service to reduce the amount of waste.

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

The crew was fantastic and the over flight was perfect as well.

They shld provide food. Between food they are giving 10 hours gap which is toooo much

The crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

I had already opted for Vegan food before 2 months yet they say we have no record for it,

Even though we left CMI late, we mostly made up the time.

Delayed almost 4 hours for a 45 minute flight with no explanation.

Again, multiple delays and I eventually just canceled and drove!

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.

The CX617 from HK to BKK was delayed more than 1.5 hours.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

They ocer booked the connecting flight. My bags took a long time to come out, nevertheless I got to the gate in time to board, but they have given my seat to another passenger. They were aware I was connecting from another flight that was a little late, but they did not care. The customer representatives were rude. A horrible experience.
