Airline reviews

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.

I had the worst experience of my life in travel. Due to circumstances beyond my control (catastrophic traffic accidents on the highway between Gold Coast and Brisbane) I missed my flight for the first time ever. Because I booked through Kayak Singapore Airlines were not interested in helping me. They told me to contact the agent that I booked through. I was extremely stressed as I had connecting flights in Europe. First Kayak told me that the next available flights were in four days time. Then they told me that they could do it but at a cost of $2600 AUD. When I agreed he told me that he was having trouble getting it through Singapore’s system and he would contact me further once it had been done. When I had not heard from him after several hours, I phoned Kayak again, spoke to a different person who said he could do it for $8200. I declined and told him to cancel the booking. The worst part of this experience was that I had booked 5 flights altogether with Singapore including Premium Economy on two legs and Singapore cancelled all my flights including the return legs leaving me with having to completely reschedule my entire trip. Kayak refunded me $2000 from $5200, obviously leaving me out of pocket. This has left me feeling that I will never deal with Kayak or Singapore Airlines again.

Crew were so busy Anna so awesome. I was in a seat that got my food nearly last but the crew were Just awesome.

I had selected seats together for my family of three when I first booked my tickets in February. However, I realized only when I checked in at the airport that the seats I had selected were no longer assigned to us and we were completely scattered across three different middle seats instead of being seated together! After requesting the Singapore staff to have us seated together on a full flight, they managed to find something but it was right next to the rest rooms and the whole journey of 15+ hours was really unpleasant. They said that the seat selection isn't locked and the airline can reallocate the seats anytime. No one ever told us this and it was a terribly unpleasant surprise. Will avoid Kayak/underpricer and Singapore in future

Limited food options. I dont like chicken or even fish but that’s the only option. Sad to say not impress

Subject: Complaint Regarding Cabin Temperature on Flight SQ447 (DAC–SIN)** Dear Singapore Airlines Customer Service, I am writing to express my disappointment regarding my recent experience on flight SQ447 from Dhaka (DAC) to Singapore (SIN). After boarding, it became apparent that the cabin air conditioning was not functioning adequately. When we initially raised the concern, a flight attendant informed us that it would take approximately 10 minutes for the temperature to cool down once the aircraft began operating. We trusted this explanation; however, the cabin remained uncomfortably warm, and many passengers—including my family—were sweating for an extended period. After approximately 45 minutes, I raised the issue again. While the attendant mentioned that adjustments had been made, the response did not reflect the seriousness of the ongoing discomfort. It was only after about an hour into the flight that the temperature finally improved and the cabin became more comfortable. I also spoke with several other passengers seated nearby, and they confirmed they were experiencing the same issue. As a frequent traveler who has always associated Singapore Airlines with high standards of service, this experience was very disappointing. It has made me reconsider choosing this route with your airline in the future. I hope you will review this incident and take the necessary steps to ensure that such situations are handled more promptly and professionally going forward. Thank you for your attention to this matter. Sincerely, Mohammed Shahriar

Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

Very concerned with guest comforts going out of their way to accommodate special dietary needs when the guests hadn’t pre-ordered.

There was no screens on the flight, and no wifi with which we could connect to the internet and stream any content. This was a smaller plan so the business class seats were a bit tight. No hot towels or welcome drinks like when you fly on the bigger TG on the same route. The food was excellent, much better than the previous Thai airways business class meals. It was also nice that they offered eye masks for easy sleeping.

HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

business class is old but still done very well by the team.

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

Although booked meal of fruit only The crew had not received this special meal The same happened on my flight Bangkok / CAN The films are so old that best is to use own computer to watch downloads . Serve nuts but they do not warm up . Service is attentive , WC clean

The flight was delayed going out of the gate at BKK that made it a difficult challenge to get through immigration transfer at tapei and make it to my departure on time. This appears to be a recurring issue. The flight crew and cabin crew were excellent. The food was very nice.

Entertainment is limited with a relatively old catalogue. Wi-Fi never works and the cabin and lavatory had evidence of a lot of scuff marks and temporary repairs. Nothing unsafe, but a bit tatty in places.

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??

Lunch Food was tasteful and had variety. Seat was comfortable. However, when I was reserving my seats during booking, the seat configuration showed was 3-3-3, but when I boarded it was a 2-4-2 configuration? Also during booking, I had also bought travel insurance together with my TG booking. However there was no confirmation of my purchase from Allianz and TG. After several emails with TG contact, sales, reservation and Allianz was i able to confirm my insurance purchase. When the policy was issued, the birth dates of me and my wife were wrongly stated and I had to go through another round of emails with Allianz to get it corrected. Otherwise any claims would be void! It was indeed not a very good booking experience!

food poor i said chiken i got pack a pow breakfast lousey .job to explain wot it was ...

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

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

Food was good but only 1 meal and 1 pie, instead of 2 meals. Both legs were late.

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

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. I got row 1 in business class and it was pathetic. No leg space, cramped space, less recline

Flight from Shanghai to Kuala Luumpur delay byy 3.5hrs with no real explanation.

The flight is awful, food isn’t very tasty or good, entertainment sucks

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 asked for more food as i was too hungry or I probably missed MAS onboard food. Both flight-attendants fulfilled my request by giving me both menus - the Nasi Lemak & the chicken noodles. Both tasted very nice. Thanks Mas. I think asked for skyjuice 5x & tomato juice twice

No food/drinks included for BOM to BKK I paid 675£ for LHR-BOM-BKK (return) flight.

Flight was delayed 110 mins.. Crew on Ground or in Air had no regrets.. No apologies... Very poor boarding process... Awful food and beverage choice.

They denied my meal which was included in ticket and also damaged my bag completely and broke the wheel and still not accepting their fault

Foreign nationals are not permitted to check in online in advance. We can only check in at the airport, so choice of seat was limited. I was stuck in a very uncomfortable location. I would expect a meal included in a flight of this duration. The food options to buy are very basic. IngiGo are a very good domestic carrier, but if they are serious about operating more international, longer haul flights, they need to improve this service to match every other airline I know.

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.

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

Worst checkin experience. Lot of delays. Checkin agents rude. Flight delayed. No regrets by the airline.

There was inordinate delay without any plausible reason. This has become a normal feature of Indigo now a days.

Flight was inordinately delayed, which has become normal with Indigo. Crews were inattentive. After landing there was a lot of time for arrival of chek in baggage

On time Arrival and Departure despite budget airline. In side the aircraft, seats and floor carpet is very clean and neat

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.

very run down aircraft. seat tilted. the mobile / magazine holder was broken. The entertainment screen was not working. The crew was good, polite and helpful

Terrible. Air India canceled my flight out of Kathmandu because of airport constructions but did not tell me. They should not be selling night flights out of Kathmandu right now that they know they will not honor. The staff was terrible and not helpful with my rebooking or compensating me.

Flight leg to and from IAD/Delhi was good. The leg to and from Delhi/KTM was terrible.

Our seat monitor did not Not work either way going to Vietnam. I had a bulkhead seat with plenty of room, but with No monitor, it was a long flight with no movies. Fun was good, staff was Excellent.

Food not of any international or even Indian standard. We have many cuisine available but only paneer & sundry items. Improve & provide some good indian items. Entertainment website or channel out of order.

Their security process is excessive. We were checked when we got off our incoming plane, at the gate and up the stairs when boarding the plane. Come on.

Interment is zero tv wasn’t work phone charger plug doesn’t work moves 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 food on board the flight was atrocious - tasteless, spicy as hell, and simply a hodge podge of nonsensical items of poor quality.
