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!!!!!!

Very bad service and food variety will never come back again

My baby was with me it was really good experience with emirates

Fantastic as ever. Great staff super catering and excellent service.

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

Everything was superb, only bad point was that the fast track on London Heathrow arrivals was not handed out to me and I had to go back to the gate to collect it.

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

You can improve in many ways First the crew in general is good, but needs to work with passion to their works not like robots Second, collecting the ear headphones long time before landing is strange The crew should deal with the passengers with respect and descent way not like giving orders

It was ok, but not what it was like 20 years ago

I couldn't hear all of the announcements. It was nice when they put them on the screen.

I liked boarding the plane. The staff were rude, the food was appalling and the chairs the most uncomfortable I have ever experienced

Delayed QF59 flight once again, Qantas doesn't fail in maintaining there delayed departures and arrivals. USB points do not work nor do the power point sockets on the plane, Qantas staff admitted that on the flight. Don't expect to your charge devices. Saving grace, was the ice cream. Bottom line, if you expect to fly to HND and make it on time avoid Qantas and if you're interested in ice cream - visit 7/11.

The flight was good, long obviously but smooth. The seats are pretty small, definitely notice a difference for long haul compared to Emirates or Cathay Pacific it’s more like medium haul seating for space. Food options were good, children’s meals were good for my fussy 3yo.

Excellent plane, smooth boarding Friendly crew Clean flight till end Food can be little better

Everything as good as can be if one flies economy bit not enough toilets!! People were queuing during the whole flight - there are really not enough toilets!!!

flight delays seems to be the norm these days. pies with soggy pastry.

Two hours late - lack of communication on why or how long.

Old plane nothing worked no charging facilities for phones etc

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.

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

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.

Flight was good but couldn’t sleep because bed was so uncomfortable.

This was the return leg of my trip. Tried to do online check in several times, both on BA App and online but it kept saying " it was not possible, check in at the airport". Got to Airport 3 hours before the flight to be told the flight was overbooked and I was on standby because I hadn't checked in online!!! Was told I could go and wait at the gate in case of a no show but would actually be booked on the next flight in 4 hours. At the gate I did actually get in to the original plane... And had 2 empty seats next to me.. So much for overbooked. To add insult to injury, my baggage did not arrive in LHR and was finally delivered over 24 hours later. I don't travel with BA very often.. This experience will make it even less likely, particularly as my wife had exactly the same issue 2 days later.

I couldn't check in over two days online, had to phone to secure a seat and at the airport they put me on standby, at the gate I had to push to get my seat allocated back to me! No catering, a small bottle of water and a biscuit. Yet business had a full meal and drinks service. Very poor.

Spent unnecessary hours on phone calls to resolve small error on one of the passengers name... It was extremely stressful and time consuming... Not great... Also all 4 members of the family: 2 parents/ 2 teenagers were allocated separate seats (even separate floors... Not great...

Absolutely the best airline for service and comfort by far! I only wish I could fly with them domestically!

Comfortable seats, good service overall. The food could’ve been a little bit better. The boarding process was slightly chaotic and in fairness, not all of that is related to the performance of British Airways.

The chairs were a bit tight even though I had extra feet space…2nd plane didn’t have entertainment and even though they said there was free WiFi-I believe the free WiFi wasn’t accessible unless u had some account set up….which I didn’t figure out

On time. Comfortable sats. Clean aircraft. Friendly crew. Good food.

Naples airport not the best ! Boarding via coach to aircraft never the best. Staff and captains announcements good. Flight on time with soft landing. Ran out of sandwiches half way down the plane. !! Not impressed. 7/10 satisfaction overall

That was awful. My flight from Zurich to London was delayed 2hours and 50 minutes. This had a significant negative impact on my work and living conditions. How can I complain?
