Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Excellent meal served with real utensils, cardboard served hot meals instead of plastic utensils and plastic covers. Quick service, friendly and accommodating stewards.

All in all the flight was good. Love the fact that for airline food it was piping hot

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

Awesome as always. I wish though the cabin for premium was upgraded.... Same old sane old :(

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

Wonderful service, planes and interior in great condition, very pleasant experience

Every thing was fine. Some ild classical Hindi movies should be add

The premium economy seats were not that great. It could have been more premium than economy seats.

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

The overall flight went well and the aircrew was pleasant.

Cathay Pacific seems to be an airline in trouble and on its way out. Lots of broken or poorly functioning things like entertainment screens, seats, and enough well trained staff to handle a full flight. Sad...

The flight crew was exceptionally good. Personal needs were well met. The food choices were very nice.

Excellent. Planes are a little older and could get some refurbishment, but besides that everything was excellent.

While I was in great pain, the seat was sufficiently comfortable to allow me to rest and not be in so much pain.

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.

Not impressed with check in desk staff at Vancouver airport. Not a professional mind service and not cared or tried to help. Don’t think I would fly with them again

Seats were very comfortable. Crew were excellent. Food very good.

Flight crew was especially thoughtful and attentive, made sure our seats were comfortable so we could rest on the long flight

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

everything was excellent the crew the food, crew was extremely friendly but wish there was a tv..📺

Flight delayed by hour for departure. No real announcements or updates until told to start boarding

The economy class sitting/chairs is tight not spacious enough to sit comfortably but for other matters everything is perfect 👍☺️

Every thing was good except our baggage that wasn’t here when we arrived, we understood the cause but hopefully we will get it soon as possible

Good one is its safety. Taking off and landing are good. The bad parts are the managements at airport, especially in Manila. It's horrible.

Flight was delayed. What’s better is if the flight stay on time.

The checkin was unacceptable. Agent took about 3-5 min minutes with me, standing in front of her, and not in acknowledging my presence. Finally, when she started processing my check in as a priority passenger, she neglected to give me a lounge pass until I reminded her . when I went to the lounge, they didn’t have me registered. However, the agent there still accepted me Did not tag my luggage as priority, so I had to wait until almost the very end before my luggage appeared. My Wi-Fi as premier elite did not work. This was not a good start to my lengthy flight.

Seats were very uncomfortable And the tv screens did not work neither did the phone charging ports. The crew was very friendly and the food was very good.

PAL Airlines is always delayed most of the time. Please try to avoid it.

Entertainment system in business class was broken. Not available during the entire trip. WIFI was difficult, kept disconnecting and required new passcode to re-connect (at additional cost, even if yo had already paid for the entire flight). In business class, they gave me free passcode, but I needed 4 of them to keep connected the entire flight.

Pros: "Surprised to get a nice meal even if flight is short and good service from the crew. Flight is uneventful and smooth"
Cons: "The 4.5 hr delay did not help. Plus the hard landing by the captain. EVA air much better but they were on strike. I think the plane was full"

WiFi didn’t work on both sectors so made killing time harder - planes clean modern and good flight crew - would do again if WiFi works

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.
