My overall experience with Singapore Airlines is great. Will definitely fly Singapore airline again.

Awesome as always. I wish though the cabin for premium was upgraded.... Same old sane old :(

I requested an aisle seat and got a middle seat The flight gate was changed and the flight was delayed

In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

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

Wonderful service, planes and interior in great condition, very pleasant experience

Every thing was fine. Some ild classical Hindi movies should be add

The premium economy seats were not that great. It could have been more premium than economy seats.

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

I did not like anything. Flight experience was bad overall.

Initial flight was cancelled so moved to an alternative flight. As a result, stuck in a middle seat. Flight then place in holding pattern prior to landing resulting in a very late trip home.

There was nothing I didn’t like, prices a little lower would help

Flight delay was informed at the last minute. Food quality is not up to Qantas standard I was unable to book an online boarding pass on any of my 6 flights.

Following a marathon flight riddled by delays and changes from Santiago, Chile, my flight to Melbourne from Sydney was on schedule but I was transferred to the next flight. The reason by ticketing and the floor manager was I missed the entry to flight by one minute! That's right, the emphasised that if I was 1 minute earlier I would be on the flight. I asked what was the point them emphasising 1minute overdue and how that helped me or the situation. They didn't care at all. Replying that if it was one minute earlier they would've done something and smirking delivering the information. Australian's do call Australia home, Qantas calls Australian's suckers.

Rescheduled after ticket purchased and issued, not 2 or 3 times and not a fourth but by 5 times, by Qantas, that's right, 5 changes! Forcing an overnight stay in Chile and need for visa. Qantas can no longer provide basic services as a national or international service provider. Professionalism is extinct and the provider needs to be mentored and educated in perfecting who to operate as an airline. Qantas is the spirit of Australian dissatisfaction.

Amazing! Was put on the earlier flight and I requested for an aisle seat and was given it. Thanks Qantas!

The staff we fantastic and seemed to work very well with each other

Business lounge in Melbourne mediocre. Look at Emirates or Qatar, Qantas! Great friendly crew. Food was good but Emirates is a level above. Business seat good. But can’t compare to Qatar. Main reason for booking Qantas is loyalty and terrific connection via Perth to LHR.

It's only a short trip from Sydney to Melbourne, which i have done many times. The trip met my expectations

The crew were amazing - A great job. They made me feel special and valued.

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

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

The cabin was quite noisy as there were lots of children travelling for the school holidays. Found the selection of movies limited.

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.

My first course flight (Aor-Kul) was cancelled in the morning, and they asked me to board the night flight hence I need to transit overnight for the 2nd flight (Kul-Myy) that supposed to be on the same day. The overnight stay was not provided, (I'm traveling with my spouse, a daughter (5 y.o.) and an infant (2 months old). Hence I booked Sama Sama Hotel at my own expense (fortunately using my enrich miles points). Other than this issue, all services is good.

Entertainment system was too old, crew were unorganised during boarding

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

No recognition for one World Emerald member. I got row 1 in business class and it was pathetic. No leg space, cramped space, less recline

Legs space in the business class cabin is too small and pillow is dirty!

Very good crew, very efficient. Unfortunately not all items listed in duty free catalog were available.

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.

Very professional and well managed. On time, great staff and comfortable.

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

not looking like a national flag carrier.. both the ground team and flight team are far from being kind and helpful. Not sure what's wrong.

Kayak company fake total I m not travel my payment reverse plzzz my credit card

I m not good serves poor serves I m m fake company kayak ok plzz my help my ticket cancel my tripe ok

Terrible experience. Unexpected wait due to staff delay was not taken proper care. Food inflight could be better where as flight attendees on flight hospitality was 100%

Aircraft used fir this route was pretty old. Seats 💺 were hard & difficult to reclaim although it was flat bed

Because of the bubble agreement b/w India and Srilanka, I was not allowed to board the flight to Columbo. My experience about airport representatives was good. They were through in their job and saved my family from getting stuck in Columbo (as I would not be able to fly to Doha because of bubble agreement). So by their prompt attention, such a catastrophe was avoided. For this reason, even without flying with them, I would rate them 7/10.

Communication was terrible. Flight was delayed for 4-5 hours in DC (on the front end, and also after we boarded, we had to get off - some issue with fueling the old plane correctly). There was little to no information on timing or what was happening. Once we reach Delhi airspace, apparently there was weather that caused us not to land - we were actually near the ground, saw the run way, and lifted back up to the sky after being sooo close. Then we circled for about 30 minutes, and they decided to go to Jaipur to land until the weather cleared and to refuel. Again, once we landed in Jaipur (wrong city), there was little to no information on timing or what was happening. Then we heard that the crew was reaching their 24 hours. We sat on the place, on the tarmac for another 3 HOURS, with no food and not enough water for everyone on the flight. Then, they kicked us off the plane with no plan, in the wrong city. We went thru customs, got our bags (thank goodness), and had to ask a bunch of staff what was happening and what to do. Eventually, their soltuion was to bus people back to Delhi (like 6 hours we were told) but not everyone would fit on the bus, and unknown timing on when it would leave. At this point it was 9PM (we were scheduled to arrive in Delhi at 11AM...). My husband and I decided to risk it and take a cab that we had to pay ourselves (about $200 US dollars) to get to Delhi (about 5 hour drive). We both had terrible trips back to the US as well - almost missed connecting flight, forced to pay for carry-on luggage (a small back pack!) and duty-free goods by the Air India staff last minute. Just terrible experience all around. Never again with AI! The ONLY good thing was the air hostesses were kind and patient - example: they made sure people with food allergies got their correct. However, the TV's did not work so I'm glad we brought our own entertainment.

The Air India lounge in Delhi , was very disappointing! The food was of poor quality and options were limited especially for vegetarians!! Beverages were fine. The in flight crew was excellent! . They helped me with my seat controls - the controls did not work without a hassle or assistance!! A very poor showing for a Business cabin!!! Post flight , the wheel chair passengers ( including Me) were “ shepherded and left waiting twice (an hour or more) before taking us to immigration! I chose to Fly Air India because I want. to patronize our National carrier with the hope that the experience will improve!!! Regrettably, I will have to look at other options for my next trip to India

It would have been perfect if there was onboard entertainment.

Food was unfit even for prisoners. larger front seats are terribly uncomfortable, which is ironic. Thorough need to upgrade aircraft on such a long route.

Interment is zero tv wasn’t work phone charger plug doesn’t work moves doesn’t work

Food could be better they need a better caterer in DC flight from India always has better food

Very very impressed with the proactive care and alertness with which ABHISHEK Chowdhary took care of us. Quietl,dignified , very alert, and meticulous. Very impressed. Also with SUNiL Kumar who was there for us in a very helpful way. SHERLY ALEX On Flight 119, BOM TO JFK CUSTOMER ON SEAT 21C, 21ST March 2024

Old fittings. Went business class. Staff not very considerate regards comfort.

Old aircraft, crew were so so. Meals were mediocre. Flight to delhi was delayed. Lounge needs update and was mediocre too.
