Airline reviews

On time boarding I would like to see ground hostess to help transit customers to direct them to the right terminal and boarding gate. Last night, all the transit customers on SQ484 arriving Singapore had to merry go round to look for terminal and boarding gate to board SQ128 transit to KL Malaysia. We went to Terminal 3 taking the Skytrain to T3 and back to T3 to get out to look for different Skytrain to T2. On arrival t2, we had to go round to ask which boarding gate to KL. We only had 5 minutes to make to the boarding time at 6:55pm but we already spent more than 30 minutes running around to find the boarding gate. We were late at the boarding gate.

Flight was delayed by baggage loading onto the plane. This was attributed to "inclement weather" (some moderate rain) which could be said to be beyond the airline's control, but the problematic part was that the plane was boarded and doors shut so that passengers sat in a cramped plane with rising temperature (full flight) for an hour. The airline was aware of the status of baggage loading, they could have deferred boarding to keep passengers comfortable.

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

This flight was 16 hours and they made it very tolerable. Seats were comfortable and the staff very accommodating. I had plenty of inflight entertainment. Food was very good.

The crew and their service was top notch, but the plane itself seemed to be on the older side and worn out. Also, the food could’ve been better. 9 out of 10.

The booking experience was bad. Our six character booking ID number disappeared the day before the flight, We could not find out what happened or what was the status of our flight, scheduled for the next day. We finally found the right number to contact Singapore Airlines on the matter (not easy). The Singapore agent worked through the issue in a little over thirty minutes on the phone, the day before the flight. That was great. I'm very happy with Singapore Airlines and their performance. Contact with a competent person on the matter was near impossible. It seems no one in business these days wants to deal with customers once they've pocketed the money. There were resellers, including Kayak, involved in the chain. When we finally got through to Underpricer, we did get a return call that could have proved helpful. But by that time the matter had been resolved by the Singapore agent. Majestic Vacations, the reseller who received the payment was less than worthless. That's just a fast buck operation. Ugh.

Excellent- a lot of food Disappointed with the premium economy pouch- did not have toothbrush and tooth paste or socks. Other airlines provide them

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

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

I loved the comfort of the flight and the hospitality of the flight attendants!

Food was hood for airline food with good poftion and variety in meals. Frequency of beverage service was very low and amount of soda with meals was inadequate.

bad… no veg food was provided eventhough i pre ordered special meal

Excellent service provided the flight crew. Food and drinks were very good.

Meal options for vegetarians can be provided… Nothing was offered for me for dinner.. crew just said no vegetarian option available and did even bother to provide any alternatives or something to eat.

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

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!

It would be nice if they could have a choice of both gluten AND dairy free menu. Lots of people have problems with BOTH. I also could not get on their website to check. Phone verification issues etc( not all of us have our phones on roaming. I tried over an hour!

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

For a transpacific flight, flying economy is awful! The seats are cramped and its meant for petite folks! Good luck if you have long legs. BOARDING - AWFUL, we got to Hong Kong - the gate was listed, but upon arrival, there was a MESS of boarding procedures, they basically DIY'ed how to board but making three lines and putting three ground crew to check for passports in the terminal area. THEN to make it worse, after going through that cattle process, all of a sudden you see people standing and looking confused, apparently we were told to get in line to board, but the AV notification wasnt even working. So people started cramming in line - worse than cattle. One saving point, the flight crew forgot to serve me dinner and after waiting for it, I fell asleep since this was a midnight flight. After letting a crew know that I was forgotten, all of my meals were served first !!! Yay for being in the economy seats! Nothing much to write home about once more!

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.
