Crew experience was more transnational, seats were so close together (LtoR and FtoB) that it was difficult to enjoy much of anything. When the person in front leaned back, there is no space for me. Sadly it was a flight to be endured not experienced.

Crew experience was more transnational, seats were so close together (LtoR and FtoB) that it was difficult to enjoy much of anything. When the person in front leaned back, there is no space for me. Sadly it was a flight to be endured not experienced.

My seat was sold off to someone else. Had to wait 9 hours to catch the next filght. Definitely will never use Cathay Pacific again. Bad, very bad airline. will comment on google reviews too.

The coffee in Premium economy and economy is terrible. That's it. Everything else is great

One of the worst flight in business class by qatar airways and I’m no stranger with qatar airways businesses class, I travelled with the extensively in the past 12 years

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.

The crew were fine. I didn’t enjoy the food at all. I found it unappetising and really had trouble eating it. The comfort level was fine and our return flight is with Cathay Pacific but honestly I probably wouldn’t fly Cathay Pacific again.

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 .

Everything was good food could be better but ok for economy on my 2nd flight the head ph jack are bad you have to hold pushed in to hear anything but other then that very nice service

Cathay much better than other options Imigration was a total mess on arrival in KL but not Cathay s fault

The crew were amazing - A great job. They made me feel special and valued.

The flight met my expectations. It left and landed on time

My bag didn’t make it but otherwise it was a great experience.

Experience was great. My only advice is to have a pasta dish on the menu. Otherwise everything was excellent.

Flights delayed multiple times, travellers requests for updates ignored. Qantas continues to desatisfy travelling basics.

I find the food in business class is just old and boring, it was once good but now just trying to hard to be "on Trend" with plant based for the minority of people, while those people can order a special meal anyway, while the majority have to suffer and loose a choice. only 2 choices for entree one boring plant based and 4 for main which two were seafood, one was plant based and one meat dish.

Packed flight. Urged to check carry-on before boarding only to discover numerous empty overhead bins after boarding. Challenging entertainment screen. After almost 20 minutes to arrive at baggage claim, waited over 30 mins before luggage was loaded on baggage claim carousel.

First flight on Quantas. High marks all around. Plus it appears as if the have a comparatively new flight. Excellent airline!

Flight LA to Sydney was first moved earlier by 2 hrs from 10:25 pm to 8:25pm roughly a week before departure. Then on actual departure date, it was delayed 2x, and needed up leaving close to 10 pm. Then entertainment for the whole flight wasn’t working for most of the seats including ours. The baby crib at the middle isle was being taped to the wall to keep it tacked in using a packing tape while passengers were walking by looking for their seats. Not projecting good confidence. After a few minutes after take off the whole crib fell off. Good the people seating next to it wast hit or got scared. At arrival at Sydney, crew handed the customs forms as we were getting out of the plane. So passengers had to scramble to find a place to fill up the forms along the corridor going to immigration. So no one is available to help from Qantas to fill up the entry forms. Not a very good experience for a flagship carrier.

flight delays seems to be the norm these days. pies with soggy pastry.

The plane was small and a little stuffy inside the plane.

Going to Xiamen they did not offer any wine and basically offered two food choices in tin trays. Something you would expect on a domestic flight in China not a $10k business class flight. The flight attendant admitted they also stopped paying for satellite Wi-Fi; which they used to offer and now don't - without apology. Normally I am a huge fan of a non-stop but the difference between Japanese or US carriers is a large one and well worth a stop in Korea or Japan rather than pay double for no amenities at all. The plane is nice, but the experience was below par.

Once on board, everything is perfect. The young and pretty flight attendants warmly welcome each passenger and demonstrate excellent service attitudes. As passengers board one after another, the flight attendants begin to inquire about our meal preferences. I requested to see a wine list and choose a suitable red wine. She replied that there were no menus or wine lists, but she would take a photo of the red wine options on her phone and show me later. After lunch, the flight attendants began to ask about dinner arrangements. It turns out that there were only three options for dinner: seafood, chicken, and beef, exactly the same as lunch.

Cons: "Shouldn’t have babies or small kids in the business class"
Pros: "There was a good amount of leg room for an economy seat"
Cons: "I wish there was a bigger movie selection"
Pros: "There was a good amount of leg room for an economy seat"
Cons: "I wish it had more movie options"
Pros: "Crew was very good and professional, yes the seats were comfortable"
Cons: "I think the Xiamen knows how to run an airline."
Cons: "They wouldn’t let us in the plane due to passport expiring within 6 months of travel. That should have been something you should have put out there during the booking process. We’re now not going on vacation and are having a hard time getting anything back from a trip we couldn’t take"
Pros: "Crew was nice"
Cons: "It was extremely loud the entire trip and after traveling for more than 24 hours beforehand, it was an extremely uncomfortable trip."
Pros: "The crew was nice"
Cons: "My tv monitor didn’t work and my wife’s chair wouldn’t stay reclined"

better handling of the checked in luggage. they destroyed mine

Should’ve not separated those who checked-in online and those who checked-in at the airport

the process of paying for the excess baggage weight, the check in process and the boarding process are subhuman. this is an airline devoid of customer service

Cebu Pac has a habit of changing boarding gates. They do a lot of remote boarding. So just be attentive to the announcements, especially if it's near your boarding time.

It was a low cost flight, so no high expectations. The experience was average.

Crew was very helpful because I used a wheelchair to get around

Flight was delayed for almost 30 minutea, I had difficulties to catch up the connecting flight. Bit due to tje well organized Singapore airport I was able to make it

The flight was delayed for 3 hours and I missed my transit flight.

Was denied early boarding for a hot seat row 1C. I asked gate attendant why I couldn’t I board as I paid extra for that seat and it’s privileges that come from purchasing it. and she said no that Cebu Pacific does not allow it. When I boarded plane finally I had nowhere to put my bag as the seats behind me had taken my overhead area. The flight attendant said that the gate attendant was wrong. I fly a lot in the philippines and to Japan and now I have no choice but to fly with Air Asia. At least they board with zones and allow rows 1-3 to board early.

I was rebook by the other airpott because of the delayed flight

6hrs fly they dont give you a glass of water from seoul to singapore need to buy drink and food plus they charge for bag on international fly is always Free 1 bag from seoul to singapore is Not a local fly you are traveling true asia same story from singapore to Bali no water drink after payment for bag drink cost more the regular airline Well never use this company again we use regular company like Delta korea japan China and even scoot parent company Singapore Air

We had 2 attempts to land at Singapore Changing during a thunderstorm. Everything was delayed by 1 hour plus.

Boarding was not accordingly after front seat, bmf then back seat. This delayed for at least 40mins or more. The staff at Jakarta can do better. Is chaos at the entry to board the plane. This tarnished Scoot reputation when everyone was talking about it.

The crew was not customer oriented at all, even confrontational . The aircraft needs more attention to detail as far as comfort, and the 1 hour sitting at the gate with no air is inexcusable

We flew on the 787 Dreamliner direct to main gate at KLIA2, quick entry via eGate and on the train 41mins after touchdown. Go well SCOOT

Was on scoot plus. The only good thing about the flight was the spacious seats. Tables and armrests were extremely dirty Food: bad Entertainment: non existent Wifi: unable to connect, then was painfully slow that we couldn’t even send messages Good thing we had a night flight, so we just slept throughout.

Not clear why boarding passes could only be issued at the counter and not through the kiosk. I had already check-in on the web, so waiting to obtain a boarding pass 1.5 hours before the actual flight defeats the purpose of early web check-in.

no charging point. food offering is limited and very much on the budget line. Overall is not satisfying for such a price and duration of flight.

We were delayed, but there was never any update given. Everyone was standing at the gate as boarding was supposed to commence at 13:10 for a 13:55 flight. We didn't actually start getting on the shuttles to the plane, until after 14:00. No updates, no information given at all.

Scoot refused to change my flight even though I had booked a flexible ticket. MyTrip wanted to charge me an extra $271 for a ticket that was only listed as $217. I complained about this to scoot and they didn't give a shite. So never again will you be getting money from me Scoot. You can Scoot off.
