Airline reviews

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

It was very good experience on board to Sydney with SQ.

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

It was an average flight. I would have expected more from this airline. Food, seats, service, etc was just average. I just give them some extra points for offering free WiFi on board with just a Krisflyer account.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

Really enjoyed the flight. Our flight attendant on the way back SIN-LAX was exceptional I didn’t get her name but she was so kind and went above and beyond to make sure I was comfortable. I had a bit of a panic attack and she checked on me a few times to make sure I was ok. Really appreciated her attention and service. Thank u

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

I was a member of Krisflyer for ten years, but my last flight to Tokyo was a disaster. I had to stand in line for four hours before check-in because they were late opening the counter, and there were more than 50 people behind me. The plane was extremely small, and the food could have been better. When I dropped off my stroller before boarding the plane, I expected to receive it upon exiting for my transfer. However, they returned the stroller to the checked baggage because they said I was late getting off the plane. Of course, I was late; they assigned me a seat at the back of the aircraft, and I was traveling with a baby! The worst part was when I arrived in Jakarta. They damaged my stroller and refused to approve my claim, so I had to pay for stroller rental because of the damage they caused. I don’t know what happened to Singapore Airlines, but I felt like I was flying with a budget airline.

From the checking, ground handlimg was very poor.seems new personal on duty,people qho suppose to be teaching them didnt see around.new people may mislead passenger, as of flt info boards, not give proper info.even informatiin counter people dont get uptodate info.makin big ques, totally disaster.guests were not happy about it.even boarding to aircraft some BC class pax sent to aft staircase, some aft pasx sent to front door.poor ground handling.may need to improove.

Nice crew.flight delay fromBKK for some ground prep issue I guess, crew serve well to guest, and respect to guest as well. As usual AC is old,and nt much comert in compare to other rehional airliners.other than that.all good

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

Flight was on time.food is as usual good.Aircraft is old.old A320, seats aithout any display.crew serve well

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.

Was got free upgrade, on old A320.aircraft is out dated kind of.bt service ,cabin manager, tried there best.and food was excelent.

When flying from Indian Sector, should be more prepared with Indian food

KAYAK Real time status update is not accurate.the flight inbound rejected and go around.and came back and land. Delay abt 30 min.still shows ontime.track ur self if u wana real time.and cabin crew s are nicer. Aircraft is jst ok.old airplane.and in midflight ,seems have some compressor issue.airconditioning was nt work properly either.I could litarary see guests were cheking if AC is working.bt on landing it start to gv cool.which probably some one intentionaly kept .which was so bad.even breathing was bit difficult.otjer than that.for me all ok.

This leg of the trip was smoother than compared to the initial trip. Sri Lankan Airlines still have much work to do to improve the overall travel experience.

Terrible experience at IST airport due to mismanagement by ground and wheelchair staff.

Some seats don’t recline. No USB port or power outlet, no inflight WIFI - not even for SMS/Messaging apps. Ontime performance was very good. They should have at least one crew member who speaks the local language, for flights like these.

Some seats don’t recline. No USB port or power outlet, no inflight WIFI - not even for SMS/Messaging apps. Ontime performance was very good.

Although we took the XL seats with more width, we found that you do not have a seat in front to stow your personal item, nor can you stretch your legs. This is not the best option for a comfortable seat. Boarding was timely but disorganized without any row based entry.

Not professional and didn’t know about double seat even when I paid for it and have a confirmation. Lack of comms between teams.

deboarding is very poor after landing it took around 45 minutes to come out.

My baggage bag got broken and only 3000 voucher was given for compensation

Crew members forgot to serve sandwiches after serving the coffee. Worst was the handling of bag. One of wheel was Broken making it useless. Though a complaint was registered and assured of compensation voucher equal to part cost of the new bag.

The seats are horrible and pathetic. The flight was delayed by over an hour as they did not have the crew

Please don’t send survey questions on Indigo flights. 90% of booking, check in, Boarding work is done by the passenger. So those questions are irrelevant

I love leaving on time and having a smooth flight

I value punctuality and customer service, which were exactly what I experienced in this flight.

Landing was smooth. Baggage check in was given complimentary B4 boarding was like a surprise gift.

If you are over 170 cm, i would implore you to select an exit row or front row seat. You will not be able to sleep. Extremely uncomfortable.

My second consecutive experience of flight delay between 1.5 and close to 2hr. Resulting upsetting my biz agenda and additional expenses on local transportation to catch up

Expensive Poor check-in process staff only arrived 2h before boarding which is not a par with international standards Cabin was overly warm No seat Pocket No in seat charging No entertainment No WiFi option Slow cabin service Limited purchasing options Boarding was good Staff were presentable Flight was safe and on time

The flight attendants were not passing out soft drinks. They skipped a lot of rows and passengers were complaining.

The boarding a bit late but overall no drama. Will fly with jetstar again someday for sure.

seat legroom was quite narrow, so i could feel the person’s knees behind me.

Honestly, I Wouldn’t fly Jetstar if I had a choice.

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.

We recently flew with AirAsia and encountered several issues. Our flight was delayed by over an hour, and both boarding and takeoff were postponed without any prior notification. Although we eventually realized there was a delay on our own, the crew did inform us afterward. To make up for lost time, the pilot took off at high speed, resulting in some turbulent moments that were quite scary. Despite these challenges, the cabin crew did an excellent job managing the situation and easing the inconvenience. Overall, while the delays and turbulence made for a stressful experience, I appreciated the crew’s efforts to keep us as comfortable as possible.

I had a wonderful experience with this company. The staff were all very friendly and helpful. Our pilot was skilled and clearly experienced. The value for the price was excellent. I would definitely recommend them.

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

My flight boarding was interrupted as gate staff said I needed visa in advance for Vietnam....

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

As usual, poor communication on delays. No info, no updates, no apologies.

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

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.
