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

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.

The boarding experience was as expected and went well. The plane's economy seating plan is not designed for a positive customer experience but rather for company profit. When the passenger in front of me reclined, the distance from the screen to my face was the span of my hand (thumb tip to pinky fingertip). There is no such thing as personal space in this setting. This results in the domino effect, for when I recline the person in back of me reclines and so it goes. This is not to say that reclining is the answer as the experience is not increased, but simply managed.

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.

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.

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

Upgrade their seats. They’ve got 20-year-old business class seats in their 777s. The food choices. On the way to Manila and the way back I thought we’re lousy compared to other carriers. The staff was fantastic and very happy.

So far pal express is much better than Cebu pacific in terms of customers service and in flight crew. And on time departure and arrival . Especially if you're taking airbus 320 plane . But the small aircraft like bombardier . It usually delayed .

Checking in was okay but boarding a little bit slow

The flight itself was good, however, the disorganization of boarding and the sheer amount of baggage STUFFED into the over head compartments in what appear to be an outdated plane was not okay. The plane was outdated. I walked into the restroom and a panel underneath the sink was on the floor. I called the attention of the stewardess and she quickly put it back into place. The entertainment system had to be rebooted in order to “work,” but even after rebooting, the sound was off. For the amount of money my wife and I paid, we expected a little bit more. Sad to say, but Phillippines Airlines missed the mark on many things going all the way to sectioning off such a small area for all the passengers to wait for boarding. Everyone was on top of each other. They also made you throw away your water, even after the initial security check. So the water you bought after the first security check wasn’t allowed onto the plane, but they didn’t offer a refill station or another place to buy water. Will definitely need to think again about booking with Philippine Airlines.

The food was ordinary, this could be improved. Sleeping was comfortable enough for several hours sleep. The layover time in Manila Mabuhay lounge for 17 hours was awful. Surely I could have been given a flight to Perth within that time on another airline. At 74 years of age I find that far too long and stressful and will probably not travel with Philippine Airlines again for that reason. The food offering on board and in the lounge was also a little underwhelming. The crew were wonderful and the flight comfort was good also.

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

The seats were very comfortable. The menu was excellent. The service was very good.

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.

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"
Pros: "Quick boarding and direct to Macau. Didn’t need to fly to HK."
Cons: "A little more leg room and a better sandwich please."

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.
