It is not so much I had bad experience with Singapore Airlines, but with Kayak and particularly Underpricer. My wife and my seat arrangements were changed some times after we booked our tickets and reserved our seats I February 14, 2026. However, after our arrival we realized that we were separated and sitting in different isles. Our return tickets indicated the same. Our several calls to your Underpricer customer care were useless as they cared how much they could charge us rather than actually help us. At the end they referred us to Singapore Airlines. If that was the solution, why did I have to call your Underpricer customer care. I will definitely erase your app from my phone and I will never use Kayak for future traveling. After all, there are so many agencies that I can use other than your company.

First time flying with Singapore airlines and I’ll give them two thumbs up 👍 👍

The food wasn’t good at all. I skipped meals .

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

The flight was very late, sitting on the plane for over an hour and missed our connecting flight from Singapore to LA. As senior citizens, we were rerouted to Copenhagen and then to LA. They should not do this to senior citizens. They should have given us a hotel voucher for a night, then catch a flight to LA the next day. Singapore Airlines should grant us some kind of credit for the next trip, if they want us to fly with them. I doubt if we will ever hear from them.

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.

plus: service and personal assistance minus: online check-in did not work

I requested an aisle seat and got a middle seat The flight gate was changed and the flight was delayed

Please have the artiste showcase of classic international movies. Please have better food. There was no dessert or yogurt in my Ind Veg meal.

Wouldn’t let us check our stroller and car seat at the gate

The staff were fantastic and the food was tasty. My check in experience was good too.

Old 777 on this route uncomfortable and in need of updating.

Frankfurt airport was awful! Brand new airport with modern technology but a process that does not keep up at all. Attitude of staff at the airport also disgraceful but that is normal in Germany. One security gate in the middle of Monday and machine clearly not working well. Immigration has 2 staff with serious attitude.

Everything was perfect. Staff were informative and professional and flight boarding, flying and de-embarking was smooth. I would certainly travel with Emirates again.

The food options were excellent for Economy. It was difficult to find the lounge after clearing security and boarding was clunky

Crew were very good. Food service was a little slow and disappointing not having on demand dining and only 3 options. Amenity kits and pyjamas were excellent.

Absolutely horrible all around especially for such a long 13-14 hour flight - terrible food - ancient entertainment - legroom worse than a short air Asia flight - not enough toilets

Everything was good up until getting off the plane. Riyadh simply cannot handle an A380. Exiting the plane on a remote stand was extremely slow and frustrating, then waiting for buses for transport back to the terminal is another disaster. Give me the 777 any day.

The first class experience was great but Frankfurt airport is very confusing. Badly signed all round. Boarding was not pleasant and check in staff was arrogant.

First Class on A380 was an incredible experience with a group of very attentive crew. The only flaw of this flight was the boarding process at Concourse C of DXB where no one was managing the queue. I was at Zone A but arrived when they were already boarding Zone C & D. There was no separate gate for Zone A & B to go through.

We still get drinks and a snack. Love the gift bags too.

Excellent airline. The plane was clean and the staff were very attentive

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

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

Terrible. It’s like they are stuck in the dark ages. I brought a standard carry on suitcase and a back pack - I was told I could only carry on 7kg per bag - in business class, I was forced to remove articles from the suitcase and put them into my backpack! That’s the most ridiculous thing I’ve ever encountered in all my years of flying. The two bags weighed the same amount but one could not be more than 7kg. Holy cow.

I give EVA 5 stars in every category. I enjoy this airline and it's great team of employees. I always highly recommend EVA to friends and family and everyone.

Thai Airways is one of the best airlines in the business. Looking forward to fly again with them.

After going back and forth with the airline, they never reimbursed the airline tickets. Went around asking multiple people how to get reimbursed and kept getting put back, not satisfied with their customer service.

Excellent service. departed on time, and arrived ahead of schedule. The whole restrictions around no food/drink is a bit weird even with Covid. Also, no mobiles and iPad use during takeoff and landing is very 2006!

Overall, very pleased with this flight. Boarding could be better because boarding was announced without a microphone so people didn’t know to line up until we heard the staff walking around to announce it. Also, had to stand in line for 10’ before we started moving. My husband who is impatient and cannot stand for too long did not like this. The rest of the flight- crew, food, and entertainment were very good.

Boarding and deviating was mediocre. At boarding they have not prioritized Business class. During debarking they prioritized premium economy. Also bus rides both times.

The flight crew and attendants are very professional and polite.

Lovely staff, comfortable seats. Transit time was short but they had great processes in place to get us on the plane.

2 hours delay, time changes started already 2 days before the flight

Poor. Flight was delay without prior notice. Poor boarding. Poor meal service. Plane was dirty and smelly. Does not worth the money.

Overall very nice airline. The seats were cloth unlike leather seats I am accustom to on planes. The food was adequate. I had to use a paper boarding pass as they do not like electronic boarding passes. I scanned my electronic pass, but the gate agent requested the paper pass. Luckily I had a paper pass, although my electronic pass worked and when the paper pass was scanned it stated I was already on board.

Was on holiday with my partner and we booked with Vietnam airlines as it not meant to be a budget airline. They separated us and made us sit at either end of the plane. Not the way I planned to spend my time on my holiday separate from my loved one. How can they separate people on the same booking. They know we are together and spending quality time together.

Vietnam airlines is just one step upper to the cheapest one (vietjet, if you wanted delays and cancel or feel like a criminal then vietjet is for you) for sure better customer cares and on time.

Jetstar was terrible. They left us without boarding passes for the connecting flight for several hours, for no reason. They should have given us the boarding passes for the connecting flight, but instead we were stuck in a “customs limbo” in Ho Chi Minh airport until very shortly before we were to board. No reason for them not to give us the connecting boarding passes.

Again another extremely chaotic boarding for the flight. Could have easily opened up more automated gates and the staff could have proactively managed the queues as they're forming rather than sitting behind the counter, waiting for the boarding to start.

My flight to Frankfurt was a very pleasant experience. The food was good, but what really stood out was the cabin crew, who were exceptionally friendly, attentive, and professional. The service was excellent—honestly, better than on some much more expensive flights I’ve taken. A wonderful experience overall!

The flight from FRA to SFO was uncomfortable. The crew allowed people to change seats after boarding finished, but then made some people move back to their seats but not others, which resulted in my wife and I having to sit in two middle seats for an 11 hour flight. The entertainment system was not working well throughout the flight, and stopped working completely around hour 8.

Review what was entered already in the same booking. Not sure we will use Arrant Grant, given what happened!

Great service food was very good and overall experience was great !!

When I fl with Bulgarian air, I am greeted with a bottle of water and a packaged cleaning wipe. There is a hot sandwich and a drink offered afterwards. Towards the end of the flight, there is a piece of chocolate and per request an additional water bottle. For the price that Lufthansa charges per ticket, it is embarassing that other airlines can offer better customer service quality on board. Also, some of the Lufthansa flight attendants act very entitled instead of being customer focused. Regularly the mobile lift for diabled passengers is missing... Every time when I fly with my 89 year old mother, she is being questioned multiple times whether it is okay to use the stairs ( she walks with two canes). Most of the times when we arrive in Frankfurt, the mobile lift is missing and she is urged to use the staircase. When I refuse to allow this, the flightattendants look at me scornfully. This is not WW2 where disabled people should be treated as second hand people... Then we all have to wait another 30 to 40 minutes on the airplane, while waiting for the mobile lift to arrrive. Does Lufthansa have enough money to waste on an airplane waiting for (on the average) 30 min for the mobile lift to come? I fly frequently and have experience mostly with Delta, United, Southwest and other American Airlines. Lufthansa needs to pick up their game on board, if they want to stay competitive and in the game...

The Linate Milano flight was delayed. Landed at Frankfort at 12:10. Then took the bus on the tarmac and the bus ride was about 20 minutes due to the airport traffic. Got off bus went to passport control, used the kiosk scanned passport, took photo and finger prints and proceeded to wait in line. I asked the attendant that I had a connecting flight at 12:50 his respond was you have to ask the other travelers in line to let you go ahead. There should be a better system. Passed passport control and the gate was at Z69 to the other end of airport. Ran there out breath, I was last person to board due to a mechanical:electrical issue plane took off 2 hours later. Lufthansa need to a better job with international connecting flight. A 1-15 minutes is not enough considering the doors typically close 15 minutes prior to take off. So the window is reduced to 1 hour with all you have to go through with a slight delay it is not enough time. The crew on the flight was excellent and received exceptional customer service.

Keep an eye on your seat assignments - ESPECIALLY if you paid for upgraded seats - the airline moved us out of our prepaid seats THREE TIMES and I could only resolve it by calling customer service - who was very helpful. Expect to carry your bags down several flights of stairs for boarding on the tarmac.

It flight had a maintenance issue, that should be part of of preventative maintenance, and then they completely mismanaged the passengers on the buses. A terrible experience.

Absolutely horrible. We missed both of our connecting flights from Frankfort due to the new border control lines. Lufthansa had us running and walking around the airport trying to rebook. They were not prepared to offer us a hotel room for the night, but finally relented when I said I was done with Lufthansa, most were not so lucky. I also put put of the blame in Kayak. You need to update which connecting flights you are offering to allow for more time to deal with the mess that is border control in the EU.
