Good service and food. For buying items on flight should be preordered as they don’t keep much stock on board.

Good service and food. For buying items on flight should be preordered as they don’t keep much stock on board.

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

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.

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.

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.

We were able to check in 48 hours before departure. The boarding was a breeze. The business' seat is very large with large tv screen. The lunch and dinner were excellent with selection of wines and other drinks. The seat was converted to a totally flat bed for sleeping which was very comfortable as well. We will definitely fly with Singapore Airline again in the future.

Sleep pods in SilverKris lounge are disappointing, showers are great though. Food decent, not amazing. Need more toilets in lounge ideally. Flight was good but service can be better.

I would not have changed anything… It was a perfect fight

Cleanliness Help for boarding and sitting Food should have been better

multiple passengers on single PNR should be allowed to update/upgrade class.

Flights were delayed, Food was good but only 1 meal instead of 2.

Comfortable seats in economy, managed a few hours sleep in an o night flight but the food was terrible. Surprising as Malaysia airlines has been good in the past. Service was mediocre this time too.

The IFE is quite unconvenient if using our own device. Not all passenger brought their own earphone/headphone.

An overnight Doha to KL. Great sleep, good service and tasty food in business class

Delayed, not enough information. Had to ask for refreshments, crew could have been more proactive

The best so far coz this time it was all male steward on the economy cluster. They were polite, efficient & genuinely courteous. They do not judge you when you ask for more food & peanuts.

No recognition for one World Emerald member. Business class seat has flat bed

I had purchased extra leg room for all legs of the flight but due to a delay in leaving Perth I was put on another flight but with Emirates. My luggage was initially lost but later found and my suitcase was broken. I ended up losing my upgrades

On-time & very well priced. All you need on a short flight.

I had been keen to try this airline and I found the food great and appreciated the metal utensils. I found the seating space smaller than most. I am 177cm and was unable to reach down and pick up something off the floor because the seat in front was too close. One of our seats couldn’t be locked in to recline and the staff were sour and unhelpful. We were on 3 flights in a row and were only provided a total of about 700ml of juice / water for the 24 hour period. I recommend taking your own bottle on board because staff will fill it for you. I had to keep asking for water and they couldn’t come up with any better solution than 100ml at a time in a cup. I asked them to give me 2 x 500ml bottles of sparkling water that we could have to ourselves and the lady I asked didn’t want to give me the whole thing until another staff member understood the problem and overrode her. It would be handy to suggest people bring a refillable bottle on board.

Sri Lankan airline had less entertainment choices and Sri Lankan national carrier did not have language choices

Very poor. The flight was delayed for over an hour. Also, our baggage, including that of many passengers, approimately 180 bags did not arrive, and we are yet to receive it.

Poor, They have damaged my luggage and I have filed a claim at Colombo airport. They promised I will be in touch by the team within next 2 days but there is no One contacted me at all after 1 week. I then follow up again and received an email acknowledging my claim and claimed that they will reply in 12 days on investigation. Again, no response at all after that… Very disappointing…

All good, on time, depart.only bad side was, airxraft is too old to be in business.hope ailine will manage somethinv somewhat.all good

Was good, comparatively. A330, with good crew set.on time depature. And crew try there best, to make thing efficient.

Spesific ,Crew and cabin manager, look after all pax on board despite being in a old A320 equipment.Got free seat upgrade as well,but old style seats, no much comfert on it.But food and the spesific crew, was amazing.maintain airlanka standerd.the cabin manager, who was so much keen,keen operate as per SOP.

The staff was absolutely phenomenal but the other elements of Sri Lankan Airlines need some serious adjustments. The day started off with terrible news that the flight was cancelled from Male and that the plane went to Malta. As an American, when such delays occur, the airlines find suitable ways to accommodate their customers such as putting them in an Airport hotel or lounge while waiting for the next flight. A 1.5 hour trip turned into 12 hours with no accommodations from the Airlines except a ticket to eat breakfast. For such a Billion dollar industry, a cheap breakfast is an insult toward the customer and something greater should have been done.

Many changes need to be addressed from airport check in to flight departure. If they observe other major airlines, then they can expect what Sri Lankan airlines need to update their procedures.

Smooth takeoff and landing. Best service experience in all our travels over the years. Caring and attentive crew. Loved our flight to and fro.

Automated check in could have been better organised and informative

We were told that flight was delayed by 20 mins, but it left close to an hour late. But they did make it up and arrived early; it's just very difficult to keep waiting when it's a late flight. Food was mediocre.

The flight has been delayed for nearly an hour, yet neither the captain nor the chief steward made an effort to explain the reason for the delay or offer any apologies to the passengers.

Boarding was nuts. Gate change. Delayed. No communication from gate staff. They seemed lost. Rest of the flight went well

It was good. The FACE check in at KLIA2 was not working.

Second time flying on AirAsia. They’re fine for a low cost carrier, so I don’t expect high level hospitality. They could have informed us that the flight would be delayed even if by a few minutes, instead of the passengers asking the gate agents why we’re not boarding 8 minutes before takeoff. And given some of the passengers on this particular flight were problematic, the crew did great handling such people.

They didn't have a single blanket for hire for a long haul overnight flight. This wasn't good enough even for a budget airline

Kayak shares with you the best price! and in my case it was Air Asia flight. Air Asia flight was on time, the boarding was seamless with FACES technology at KLIA2 and the pilot made a great smooth landing upon arrival. Excellent trip!

By the time the “sell “ cart came around to row 17 they were out of several items. This happened both leaving and arriving in Kuala Lumpur. Poor planning.

I don’t fly also same as previous no refund even it’s airlines or agency mistake

First time flying with VietJet Air is so so. Check-in process for domestic is okay and easy but during our flight back to Manila, the ground staff at Tan Son Nhat International Airport weighed our hand luggage before boarding when in fact, it should be weighed during the check-in process. They are very strict in terms of the 7kg hand carry it’s either you’ll pay extra, or leave things behind.

I was unable to check in online so had to line up at the airport. When I got to the counter? The staff told me I had to check my carry on luggage, which cost $70. When I boarded the plane, I saw many suitcases that were bigger and heavier than my carry on… so not sure how they were able to bring them on and I wasn’t …

The flight was OK, but you need to warn passengers going to Vietnam that the full first, middle and last name needs to be in the issued visa, At least 5 passengers on that pane did not have that. We all had to pay $298 each to some agent to amend the visa. At least one lady could not and was left behind.

Our flight was delayed for about 3hours however the ground crew made it sure that we will not miss our connecting flight from Hanoi to incheon.

Not punctual in departure and seats are very tight and narrow. Crew should handle noisy families during flight.

Very bad experience and will never try their service again. Not even water serve for 8hr flight. Will have to wait for every prepurched to cimplete before can buy water.

They do not even give you water. Have to pay for that and not cheap. Staff had some friendly and some very unfriendly. Terrible experience

Flight was okay. Seats were a bit cramped and not that comfortable, especially for a 7-hour flight, but you get what you pay for. Food has to be bought also so plan ahead. But if you can tolerate it then it’s not a bad deal! Staff are nice too.

Trip was only 40 minutes in duration....no food and no entertainment. Otherwise it was excellent!

I wasn’t able checkin on line so wasn’t given option buy food so I had to site watch everyone eat when I was hungry. That’s F-up
