The seats were more narrow than at other lines. Food was mediocre (economy class)

The seats were more narrow than at other lines. Food was mediocre (economy class)

The crew have great customer service but their economy seating isn’t the most comfortable for a 220lbs+ guy and the food wasn’t bad, but wasn’t exceptional, either.

Food option Hindu veg to Hindu non veg request was unheard

They made 22 hours aboard aircraft very enjoyable. I was very impressed with the attention to detail and level of service. Singapore airline will be my preferred choice going forward.

Could not really fault anything. We had a really short time between flights (about 45 mins), and had to get across the other side of the terminal. But we made it and crew were helpful. Food was good and service for the kids was great.

On time, friendly staff and decent food. Would definitely recommend.

My daughter and I had a pleasant trip to Singapore. Reliable and on time.

A 16 hour flight from Singapore to Los Angeles had only 2 meals. It would be great to have 3 meals.

The experience was poor in comparison to the flight to Manado from Singapore via Scoot. Gate against could only check in stroller to Singapore (by clearing immigration) or to Brisbane. Who is able to carry their baby for 7 hour transit without having to enter Singapore?

Good airlines, travelled 🧳 n Singapore multiple times and experience is consistent

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~

I was really impressed with the experience it was my first trip overseas. Nice staff

Not enough food for everyone. . Always run out of food when we ask

Customer service was exceptional. I heard it wasn’t a great airline, my opinion has changed after flying with them

I was amazed at how clean Cathay Pacific planes were compared to our US domestic airlines. Everything was great all but the food service I was just okay with. Shorter flights with other airlines usually provided more meals and snacks that I have been on. Almost a 16 hour flight just two meals and no snacks with Cathay Pacific. Even ran out of what I wanted for one of them. Other than that top notch!

Cathay was not the problem. The problem was the customer service from Kayak/Underprice. Will never book through Kayak again.

The crews were smiling all the time with soft tunes when they spoke; the food was excellent. Thank you!

Cathay flight was fine, Amsterdam airport was a nightmare, spent way too much time walking to our next connection, no travelators.

Mediocre. Nothing special. Bad airline food Never received the food I requested Slow response from ground staff concerning my wheelchair. I was left at a holding area and had to walk the distance to the gate. In Hong Kong

Bathroom was not cleaned as often as other airlines does. It was gross for a less than full flight capacity.

Not a frequent user of their website booking. Booked my check-in baggage and only realized that I did not book my check in baggage for return flight. The receipt was not clear in identifying that as well. Was charged exorbitantly at check in counter. Bad taste for sure when it is a business trip and not leisure trip. Baggage was delayed for more than an hour at belt back in SG.

Boarding took forever. It's also weird that we paid more (for preferred seats) to get on the plane last. Inflight WiFi never worked the entire trip. I want my money back.

The cosmetic condition was pretty run down. The carpets were badly worn out. Even the paint on the wings was chipped and peeled! Looks like they are running these 787s to the ground..

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.
