The friendliness of the attendants, and the quality of the service.

The friendliness of the attendants, and the quality of the service.

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

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

My groups frequent flyer star allianceUnited airline miles was not accepted. The Singapore premium economy bag had to be requested, it was very lacking- no toothbrush. I paid more than double than economy but could only use the bathrooms sharing with economy which was hardly available and had to wait in line. Is the 2X $ worth it just for a larger seat???? It is questionable. Seats were not that comfortable. My husband’s seat had white stains on it- had to wipe it down. Our headphones did not have covers on it. Food- way too much.

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.

Overall good experience, convenient Changi Airport, even the layover was long.

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.

They made me check my carry on even though there was room We un boarded in a strange way but overall it was good

A very small gate at Singapore airport, lots of people packed into a small area…. A Petrie dish for infection. The flight was late although the captain did make up time. We had an aisle and middle economy class seat on the plane. The flight appeared to be very full. The seats were small, hard and very uncomfortable with minimal leg room. I’m a small woman and felt really cramped. My husband is a big man and stated he was unable to move at all in his seat. We were given 2 meals during the flight from Singapore to Brisbane. Our first meal was okay at best but the second meal was inedible. I think it was supposed to be veg in pastry but the pastry was full of air with minimal if any filling. The staff were pleasant and efficient. Getting off the plane went without any problems. It did take an extended period of time for our bags to come out onto the carousel. For the best ‘airline’ in the world, it was pretty poor. If Singapore is the best, what are the others like?

I cancelled my family 2023 international vacation because you guys double booked me with the same date, passengers, airlines and just hours difference and did not want to refund me at the right time and then finally cancelled the extra booking! Cancelling the booking that I personally booked! And you guys kept the unauthorized booking! This experience was really bad! Ruined everything! Never again I will book with kayak , me , my family , my friends and most importantly I will advocate to everyone to make sure not to book with Kayak! None existing customers service! Only 3rd provider that serve only their company and not the travelers!!!!!!

It was a really good experience. Food, snacks, and beverages were good. Flight entertainment was also a good one.

There was 2 hours delay before boarding and 2 hours delay after boarding while waiting in the plane

Flight was late over a hour just like the first one. WiFi was down.

Old cabine without flat bed in business for a 12 hour flight is not acceptable

They charge me for luggage which is was included on the ticket

worst experience ever i choose my seat in advance and also have my seat selected in my boarding and the they told me that my seat has been changed without notify me

Food could have been better especially the breakfast. Overall it was a good flight

We transited through Chad and what was supposed to be a 1hr 20 minutes transit time lasted over 4hrs. We didn't get regular updates until we complained. After a 10hr flight from Paris no form of refreshment given and finally arrived Abuja over 6hrs later and none of my bags came

The line at boarding was not well organized and managed

My seat was so uncomfortable, and the headrest was broken. Very very disappointing for the price I paid.

Flew first class. Was excellent. Lovely crew. Seats were amazing and could convert to flat bed on the A320 we Flew. Good food and drinks choices.

First off, it wasn't clear that my first flight was to be operated by IndiGO. While the flight itself was fine, this meant that my whole initial check in where I would've properly verified my seating on my Qatar flight/requested an upgrade was impeded by the fact that I had to check in with IndiGO. They said I would separately have to go to Qatar counter to deal with second flight leg issues, which was impossible given how long the check in took/no time available to do so.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

It was excellent in all respects. I don’t think it needs any improvement

I was denied lounge facility at airport. Explanation was not satisfactory.

Good staff, good intent, decent entertainment. More seat space would always be of benefit

I liked the overall service and comfort. The only annoying thing was paying for excess baggage at the airport. They have limited options and they don't take all cards.

The plane from Dublin to Doha was quite comfortable. I was in economy and the seats and rows were very tight. The man in front of me reclined his seat and it made my screen incredibly close to my face and I wasn’t able to take my tray down and my knees were pressed against the seat. I had to ask three times for him to pull his seat up but in his defence he hadn’t even reclined it far, the rows were just too close. I had a pain in my side by the end of the flight from the chairs which were quite worn and not very padded or supportive. It was a significantly inferior plane to the plane from Doha to Sydney and vice versa.

food in Qatar was terrible. I had ordered asian vegetarian meal but the food lacked any flavor. Choices of entertainment was also very limited. emirates is way better in terms of food and entertainment.

BLR boarding is total pathetic. Should not fly Qatar from Bengaluru. Check in staff is too rude there

The food was nice and the toilets were kept clean. I find the cabin bag policy to be ludicrous though, there's no way someone can have a small personal item and carry-on cabin bag weighing <7kg if you need to take a laptop with you, meds, and any valuables and items you can't risk to leave in a cargo bag that may get left behind

The cabin crew were kind, helpful, and polite. However, my flight from Abu Dhabi to Frankfurt was delayed, causing me to miss my connecting flight. As a result, my journey was significantly extended, leading to a much longer travel time than originally scheduled.

Maybe some more information as to why the flight got delayed I understand may be tell your customers that missiles were fired at a specific airport wouldn't be reassuring to the customers and would cause mayhem but something like recent events have cause a delay on your flight or smth

It was great! Kept the time. Provided what was promised

I booked and paid for a Business Class seat for myself and my wife. 4 hours before the flight i get a call saying the plane they sent doesn't have the correct layout to accommodate all the business class seats they sold me 3 months earlier at a premium of $1500 a ticket. So they have to bump me from Business to Economy and will give me a $400 credit (total of $800 for both seats) that I could turn in at Abu Dahbi for $400 in US cash. They then promised a row that we could have to ourselves and the arm rests would go up so we could spread out for each of us. My wife was taken care of but I was put in the exit row with the flight attendents set as part of the three...and the arm rest did not go up. When we got to Abu Dahbi, they would not exchange our credit for cash as promised. Very disappointed they took my money 3 months ago and refused to reimburse for the change in seats or follow the promises made.

The WiFi was not compatible on both my phones (Vivo Y30 5g and Samsung Galaxy A32) with up-to-date android software.

Flight was delayed due to slow boarding process by etihad. Update food options and movies as well.

Only 1 time food and drinks together was offered, for total 5 hours duration drinks and snacks was never offered. For some people food choice was not available, only veg was available. No entertainment option was there. Crew members were mostly back of the flight asking each other for KitKat and chips to share between them.

1st of all on February 27th Abu Dhabi to Delhi flight the seat wasn't comfortable at all, coming back the Lounge at Abu Dhabi didn't have anything. Than the Food in the flight

Entertainment did not work from flight from Abu Dhabi to Kolkata. Emirates has a much better flight in that sector.

More entertainment channels and better food, whatever food requirement you select.

The flight from NY to Bangalore was very good but the return flight from Bahrain to NY was mediocre

The Senior Flight attendant was just amazing on our Flight GF 284 on 30/11/25. She was so attentive, helpful and caring not just to us but to all in our cabin.

Loading was on time and quick Not very many people

Amazing business class in a single aisle plane. Fully flat seats, pyjamas, amenity kits, all in all a really complete product. Service was good - not amazing - but they did a good job. Got a few hours sleep. Will fly with them again if I can.

Did not have to leave plane. However found the wait tiring with nearly a full plane boarding at Male and being unable to get out of seat due to cleaners security and a full plane boarding with hand luggage. Staff were excellent despite a long and tiring flight due to stopover.

Everything about our return trip from Colombo to Manchester was excellent. Staff were brilliant all flights. Return flights on time and all staff were brilliant. The outbound journey however was marred by cancellation of Man to Bahrain flight. No information or staff assistance. Customer Service none existent. Told to make own arrangements by none interested or understanding telephone staff who said to make own hotel arrangements and be reimbursed. CS refused to reimburse hotel or lost lounge booking or taxi fees.

I like it very much. Gulf Air is always the topper rank of the world. I love it very much.

The drinks should come before food. Unable to have any fluid unless after food. Thanks

The flight was a transit and I had my boarding pass from the departure. I have talked to the check in person to set me up close to my family seats and ended up with my wife in one seat, 3 years old son in different seat and myself on different seat. very disappointing and overwhelming.
