Airline reviews

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.

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

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.

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.

Service excellent would chose Singapore airlines as my first choice

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.

On time, friendly staff and decent food. Would definitely recommend.

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

They bumped us up. They overbooked the flight and we hurried to the next flight. We are a family of 5 with 13, 10 , and 6 year olds kids. Everybody was running to the next flight. We never been exhausted in our flights hust like we have experienced this week. Mismanagement in scoot and kayak.

Crews are not allowed to perform any service whenever the captain deems there’s a chance of turbulence. Even if it is perfectly smooth air.

I enjoy flying with Thai Airways, however their B788 business class configuration is quite dated. Additionally , while the service is always friendly and efficient, I’m getting tired of the same “usual suspects” when it comes to food choices. Since it was a lunchtime flight, what about some gourmet sandwiches or some type of salad dish for the main course? The entertainment options are also quite limited and this is not unique to TG, so much so that given the short duration of the flight I ended up not bothering with any entertainment. Finally, despite signs around the cabin advising wifi available, I was unable to con-net and in fact I’ve never been able to connect on any TG flight over the last year or so - what’s the go here??

Always liked Thai Airways but in the past they have been very expensive, not being a millionaire just yet, I will use cheaper airlines. Bangkok to London £370 11 hours 45 mins. Old plane but ok. Lovely ladies on board, very polite. Food was ok. Will always use them if the price is right.

Could have been better. I prefer Thai airlines only but it hasnt been reliable.

Service on board was excellent. Flight attendant was very helpful. I wish the website is more functional. I can't even choose seats online and had to call the customer service. During check-in at the counter in CGK, I saw a printed page about paying for the bulkhead and exit row seats, so I asked the staff at the check-in counter. I was told that the flight is full and there isn't any seats available for paid upgrade. When I boarded the plane, I saw so many bulkhead and exit row seats empty and asked the flight attendant. He allowed me to purchase the upgrades on board. It would have been nice if I could purchase the upgrades ahead of time, eg. During online check-in or bag drop at the airport. The economy seats in the A350-900 are arranged in 3-3-3 configuration. Seat width is a bit tight for me.

Overall things were very good and orderly. The food was very good but I want able to get a second drink very easily, so that could have been better for services. The seats seemed to be lacking legroom but I'm also 6'1" so I'm used to wanting more legroom but the plane seemed smaller then others when it came to legroom. My kids all enjoyed the entertainment as did I so that was perfect!

The flight attendants ignored us several times which was annoying. The sandwich thing wasn't very good but it's only an hour flight, it would have been better to have entertainment over bad food.

It was good overall. At 6 foot 1 it's hard to say anything seat on a flight is comfortable but it would be nice to have more legroom. The meals were good but would have liked to get wine much sooner.

Extra seat belt across the chest 10 minutes before taking off and 15 minutes before landing seemed excessively safe.

The transfer from Domestic and International was a bit confusing but I am easily confused. I did not eat any food, but the food on the other leg was decent. It was nice they turned the lights off on the night flight. The plane was in good shape, but was a little cramped in economy and I am small. They gave me a customs form to fill out and nobody looked at it as I went through customs. Not a bad flight.

My case was missing a wheel on arrival Heathrow and the staff were unhelpful when i tried to get some compensation stating it was not sufficient damage, i only wish that they at some point have to deal with the same situation it put me in, maybe they would change their attitude but overall it was a good flight

The flight isn’t great, as the plane has faulty with light and noise. It blinks and make noise for 8hrs non stop! Causing health and sensory issues! Causing Hazard matter to all 3 babies that on bassinet seats. This matters affected 12 passengers and the most horrible flight I ever experience. Have been flying with MAS for more 30yrs and this is the worst! Very disappointed

AC not working, just slowly blowing room temperature air. Long taxi time does not help as well. Sweating all over the whole trip.

Did not take as cancelled 3 time so took another airline

It was a 2-hour flight so they didn't have much time for serving food. There was some turbulence so they could not serve hot coffee or tea for the safety reason. Good service, good tasting food, nice plane, a little bit of delay.

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.

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.

Did not like that we were not informed about the 4 hour delay, crew not friendly, noone at terminals to consult with...all employees for Batrik were behind glass aftervgoing through security at the gate again. Why no agent at Gate H 10 to answer questions? And no apology. Updates would have eased anxiety. Boarding is disorderly also.

During this flight all the crew just focused on making money by selling food and drinks. There was only one washroom open. And it really smelled bad and wasn’t usable. Even to watch something onboard entertainment u have to rent headphones pathetic airline but only one with direct flight so pretty much the only option from Karachi to KL

Delayed for 3 hours, need to pay extra for drinking water.

The OD2204 KUL-LGK was delayed 40 minutes due to air-condition malfuntion, after inspection the technician give green light for the flight to go as usual but the air-condition is still not working properly, passengers complaining to the stewardess but they cannot do anything, I did tweet to @malindoair to complaint but no reply from them … hope this Batik Air is not having problem like Rayani Air and I do hope the management do respond to my complaint as well

Nasi lemak was horrible. Plain white rice, tasteless sambal, no cucumber, no kacang, no ikan bilis. And the chicken was colourless and tasteless, tasted like boiled chicken. Entertainment system didn't work at all.

2 delayed flights - hotel layover in a different country- lost baggage.

Silly to not even offer people water for free when they are paying so much for tickets.

You get what you pay for. It’s functional and gets you from point A to B in good comfort. However, food options are limited and cash only, Crew is a hit and miss .. they get your attention if you reach out.

Good leg room ... air conditioning was a bit warm don't Book row 8 ... no windows

They got to the terminal late, with no one on the arriving flight, boarded us late, and left us sitting there for 2 hours before they got us off the ground. They knew they were going to be late, yet they never got an updated flight plan from their head office until long after the flight was supposed to leave. They could have cut the delay in half, of at least let us stay in the terminal. Really just horrible planning.
