Good flight. Fiod was ready a bit late hence a hurry to finish before landing. Excellent crew and service

Great to have actual hot tastey meal on a flight. Well done

Cabin Crew always friendly and helpful. Seating cramped - foul smelling from toilets, high risk of disease. Guard personal property such as expensive sunglasses Coffee always awful and cold Meal trays toddler sized Not worth the extra cost to fly SQ - use a budget airline, same if not better experience

When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

A pc of cake or biscuit at least. The airport was like a maze need to take another bus to the main terminal to immigration.

Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline

They were able to assist my elderly father and myself after not being able to check in to scoot. The counter service was phenomenal. They did what they could to get us on the next plane so we could catch our Connecting flight. Scoot closed early on us so we ended up missing our flight.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

Transfer within the same terminal and lots of facilities at the airport.

I cancelled the flights in good time but could only get a partial refund. I was not warned of this.

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.

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.

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

Very comfortable flights. Not so many new releases in terms of films.

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 .

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

Flight was delayed. Drink was only offered during meal. Would have been nicer if crew walk around to offer drink after take off or in between meals.

Halal food options could have been better the first meal portion sizes were very small the second breakfast meal the fish and couscous was very dry and disappointing I enjoyed the Hong Kong t lot I enjoyed the midnight stuck a lot the Hong Kong tea we had for breakfast was very good

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.

Not a pleasant experience from the start of booking first flight all the way through to the actually flight. Only saving grace is the food.

No power on an 11 hour flight? What a joke. Crew did not come by enough to get trash or offer water.

Checking in was okay but boarding a little bit slow

There is a problem with the sound while watching movie or listening to the music ( the sound is static & goes on and off). Aside from the sound, the experience was good & stewardesses are nice.

Not leave 12 hours late. This airline is horrible always late does not refund upgrades for cancelled flights inept counter staff.. needs to be shutdown

The food was good but could be better. Also, less salt would be nice.

My biggest concern was with all the schedule changes. Both inbound and outbound flights times were changed, including a time change less than two days before the scheduled departure.

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 charges for overweight luggage were not clear, I think I paid twice, I didn’t argue because I was traveling alone & already felt exhausted.

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.
