Singapore Airlines has set the bar for the other airlines at a very high level. Outstanding service from start to finish.

Had to take a shuttle bus from boarding gate to the plane and climb steps to the plane. I already knew 737-Max 8 was a small plane with only two toilets at the back for the entire economy cabin. If you sit among the last 5-6 rows closer to the toilet you will have passengers standing at the single aisle queuing to go toilet next to you as there could be more than 5-6 of them waiting at each time especially after meals. That said the crew was prompt to ensure the toilets were checked and in good order at intervals and they remained clean for use. The plane ride took close to 6 hours rather than 6.5h and despite taking off late some 25 minutes we arrived ahead of the scheduled time due to a shorter flight duration. In-Flight was challenging due to narrow aisle and quite slow. Food for breakfast was served rather late and a bit of rice grains were not fully cooked. good variety of juices and fruits + yogurt served. Flight was smooth.

Poor boarding and unboarding proceas. Multiple errors made by Singapore Airlines throughout the check in process.

I paid extra for assigned seating. When I checked in my seat had been changed to middle seat middle aisle. There was a reason I paid for an aisle seat. I did not sleep the entire 14 hour flight, preceded by a five hour flight from Kathmandu to Singapore. When I arrived in San Francisco, I had gone 40 hours without sleep. My immune system was compromised and I caught RSV flu. These days I hate flying!

I purchased my two tickets on February 2025. Tickets were by each other, aisle and window. However, when we were boarded the assigned seats were one by the window and the other one in the middle of the four seated row. It was a horrible experience and we had to tolerate 17 hours of flight seating by different people. If the airline changes the seat arrangement, it should have the decency to notify the passengers in advance. I have checked my return tickets to Los Angeles, and I have noticed that they are not by each other and I don’t know what to do. I hope someone contacts me and rectify this mistake.

It was all good. Lovely attention by the crew. I lost my glasses but they did everything and eventually found them. They clean the toilets regularly which is a big plus for me.

On schedule, courteous, and efficient. Old aircraft with not so nice lavatories.

The A350 3-3-3 configuration is cramped and uncomfortable. The seats dig in to the contact points with your body. The aisles are now too narrow for passengers and crew to pass with ease. I was in an seat but the passenger in front was laid back for the majority of the flight meaning I had to do the same. There was a kid in the seat next to me who wriggled all night which kept waking me up. If fact there were too many kids on board - why weren't they at school? Babies crying too. It was like a Kindergarten. Singapore Airlines in barely getting above Jetstar these days. It seems to have gone downhill since merging with Air India, The evening meal of fish and noodles was average. the morning breakfast of a pie was poor. At least the alcohol flow kept some sanity. The film choice was good, but I'd already seen the good stuff on the way out. The crew are still amazing and the service set the airline apart. A shame about the packed plane with inconsiderate passengers.

Food was excellent.. better if there are more movies selection.

Had picked seats while booking tickets but airlines reshuffled the seats without informing and we were again left with the worst possible seats on the return journey. terrible experience.

Food no choice just give it seams trying to finish what ever you have in hand

They wouldn't let me on the plane. The 3rd party apparently didn't pay for the tickets properly?

Did not take as cancelled 3 time so took another airline

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

Ok, but legspace on MH0127 from Kul to Per was too small. It was not possible to tilt my seat which I don't understand because the seat in front of my could do it. So I didn't rest on the flight. Also, the crew was probably understaffed because it took very long time to take trash after the meal. Everything very different from the flight with Malaysian Airlines from London to KL.

Service / food has to be much better. Staff were not very attentive to requests. Requested for a second serve of coke and got a weird look back from the host! Was also told they don’t have extra water bottles when I requested for one before sleep! Dinner time food was very minimum and average.

chaos boarding. Crew in business class seemed short staffed and lacking in attention to details initially, but did improve during flight.

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

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

Personable, friendly service. Crew interactions always naturally pleasant and polite. The crew really enjoy their job and interactions with one another. Public Addresses are all smooth, clear and unambiguous - this instils confidence. Landing was butter-smooth in what seemed to be challenging and turbulent conditions - Kudos to the flight crew. Boarding and airport experience were good also.

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.

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.

Very quick turn around, plane was in good condition, alles paletti.

Instead of landing we had to go around and landed in Kuala Lumpur International Airport instead of Subang. Then we had to restart and arrived over 2.5 hrs late

Premium check in was worth it. Boarding process was a little chaotic. Seats were super cramped and I am less than 80kg and 180cm

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

should remind people who cough must wear the mask. A few persons surrounding keep coughing.

Air Asia’s standard has dropped tremendously post pandemic. The whole organisation feels ‘soul-less’

No complaints. Made it on time with a minimum of hassle. Some complementary soft drinks would have been nice tho.

I regret flying air Asia everytime I fly them. Baggage policy is a joke and the fact they issue mobile boarding passes but you can’t ever use them?? A waste of everyone’s time (you can only use them flying out of bangkok or KL)

100% dislike due to last minutes flight cancellations and terrible customer service experience. Do notice us early at least 24 hours before departure time.

Crew was polite. Ground crew was prompt in informing about the flight delay. Boarding process was ok. There was no entertainment on the flight. Blankets were not available for an overnight flight. It was very cold & blanket was given upon request. Food was average. It would have been better to serve breakfast instead of a late night dinner as people like to sleep & serving breakfast before disembarking in the morning at Singapore would have been much appreciated. Seats were ok. Plane was old.

Flight was cancelled by air India. There was no explanation provided why the flight was cancelled. Found out that the flight was cancelled because the Iran air space was closed. Meanwhile, all other flights passing through that region were operating without issues. When asked to refund money for the tickets, being told that “ As checked, we wish to share that Flight AI 116 on 15 January 2026 from New York to Mumbai was cancelled due to Iran airspace closure, which were beyond the airline’s control. While such events can disrupt travel plans, we appreciate your understanding and patience. Our team remains committed to ensuring the safety and comfort of all passengers and takes all necessary measures to minimize any issues. However, we must inform you that compensation is not applicable under these extraordinary circumstances, in accordance with the relevant regulations.” Completed unacceptable and unprofessional behavior!

The flight was on time, the entire experience was very smooth. The Flight crew were incredibly professional and nice. Made us feel very comfortable

The planes are dated and need upgrades. Seats are not comfortable and entertainment equipment doesn’t work

Boarding and crew were nice Food was normal No entertainment was on the flight. Neither TV screen was there nor Wi-Fi connection to the mobile phone or iPad was there. Even the budget wing of AIR INDIA ie AIR INDIA EXPRESS provided us Wi-Fi connectivity on our mobile phone in their DOMESTIC SECTOR. So not providing Wi-Fi connectivity on international flight was unthinkable.

The flight taking off from BOM was delayed by 3 hours - making a 15 hour journey into a 18 hour journey!

The aircraft was newer 777 model and had comfortable seats and plenty of leg room even for basic economic ticket. Air India is upgrading their fleet and I was fortunate to fly on one of the newer aircraft this time. The direct flight is definitely convenient if you do not mind sitting in the aircraft for 15+ hours

The flight was very good, it was on time at the take off and before time at landing. Overall it was a great experience !!!

Food too spicy for non Indians. Not enough food options were available for the passengers sitting towards the end. They should rotate serving people from the back as well not always from the front. My TV and most of theTVs not working. For long flight its very important to fix the TVs. Seats were broken and dirty. Tray tables were wobbly. Foot rest didn’t stay in place.

Entertainment system was not available in Delhi-Ahmedabad flight. The flight was delayed for take off by 30 mins
