It was really nice experience by flying this klm flight.I personally recommend everyone to please try this klm flight

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

The service was great. However the lounge only gets passing grade

Flight left a few minutes late, but that's it. I wish the seats could be wider and recline more.

Was trying to change a flight but told that Canadian and local klm systems do not interact so they could not access my booking. Overall I like klm a lot but if it was important to change flights I would be very frustrated.

KLM is my favourite airline. Never ever let us down.Staff are first class.

Quick and efficient as always. Air France managed to loose and damage my luggage that never made it onto my KLM flight.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

Boarding in NCL is really bad. I'm sure part of that is a directive from the airport that KLM can't change but part of that is due to KLM policy. NCL doesn't announce the gate of departure until 30 minutes before departure. However, when you arrive at the gate area, the gate agents file everyone into one long line and everyone boards from one line at one time. This line can stretch for 200m...easily. There is a separate line for groups 1 and 2 but you don't know it until you get to the gate area and agents don't announce/advertise it. Everyone else is grouped into one line. Are you in group 3? Doesn't matter...you board with group 5. Traveling with a child? Tough luck...you're stuck at the end of the line and board last. The last part is very annoying because none of the gates at NCL (with the exception of 1 used by Emirates) has a jetway. To board, you must leave the gate area, walk downstairs, walk onto the tarmac and walk up stairs to board the plane. Highly challenging if you're traveling with small children. That boarding process begs for a concession to allow people with children to board first because they will need extra time. But there is no such policy. Just a really horrible boarding experience all around.

My seat/bed broke. Flight was delayed. Most of the cabin crew were very pleasant. Amenity kit was nice. Chairs and cabin was worn. Food was mostly quite nice.

The crew were kind and very helpful. Did not expect food service. Was served a warm soft sandwich bread , was delicious. Overall the service, the staff were great. Highly recommend others to try Turkish Airline

Cabin was kept very hot and it was uncomfortable. Entertainment system did not work at my seat. Crew and service is fantastic

Turkish Airline canceled our tickets in the very last minute, with our luggage and everything else, all prepared and good to go. It’s clear that they sold the tickets for better money to someone else. Bad, Bad, Bad business!!!

My experience with Turkish Airlines was good. I didn’t get the meal I ordered. So I didn’t have anything to eat which was disappointing.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

It was ok. Not the experience I expected from Turkish airlines

Small seat space for 13 hours flight, they charged for baggage , very bad quality of food,

The crew was amazing. Super polite and welcoming. Excellent communication and service.

The seat did not recline and we called the stewardess, he forced it to recline, but when we landed, it did not come forward because the seat was broken. The stewardess came, He tried to do it but couldn't do it, the flight commander came and spoke to us in a bad tone, telling us to get out of here, she waited at the head and acted as if there was a child and we couldn't get up, it was very shameful, I don't even know if it's true, but she said if you don't get up, the plane will not land and will keep turning around. Then a passenger pushed the seat from behind and it worked. Then we wanted to talk to the supervisor again, but she did not come next to us. We fly so much and this is the first time we encountered such a style.

Food and service were excellent. The lack of seat monitors for movies etc was a negative.

Excellent business class seats, service and food. No airline does it better.

One of our bags was never put on the flight in Copenhagen. Now that we're home in the USA, my wife is still without most of her clothes and personal items as she returns to work this week. Hoping for a quick resolution, but there seems to be little chance of speaking with an actual person in the process.

Scandinavian was perfect. Nice A350 with an on time departure and an an experienced crew. What a difference from TAP.

SAS has too many other airliners. They don't need to exist.

Food could have been better. My pasta was microwaved into a solid block. Inedible.

Crew was unresponsive to request for a soda. Food was horrible and I’d venture to guess many others thought so as well by the amount that they trashed. Made me sick to my stomach and ended up in bed the remainder of the day once we arrived. Screaming child for 3/4 of the almost 8 hour flight. Crew had no headphones whatsoever for free or purchase. Seating way too tight and we upgraded our seats. I do not see us ever flying this airline again.

They cancelled our flight home less than 24 hours before it was supposed to leave. It partially ruined our last day because I was on the phone trying to get 5 people home and the stress that it causes. We still arrived at the airport with no definite flight plans. The actual flight was good but my kids really misses the kids meals I had ordered for them which obviously didn’t make it to the new flight.

They were all bad because SAS was at fault and cost me my time. I will never fly SAS again.

The flights from EWR to Stockholm and from Copenhagen to JFK were great. Love everything from SAS

Boarding staff at lahore airport corporate well. Thanks to that guy.

Flight got canceled due to Middle East conflict. Just fly hasn’t refunded me the money

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

On this flight...fine. The one from India to Abu Dahbi, awful.

One of your male flight attendant was pushy and a bit of a martinette. Completely unnecessary.

second leg was more comfortable. Customer service in Abu Dhabi is okay.

My wife and I were upgraded to Business Class on our Dublin-Abu-Dhabi flight on the 22nd of January. Being served by "Mariyan" (not too sure about her name, she's from Tunisia) was the real highlight of our flight, she deserves to be working with etihad. We are looking forward to the next upgrade as we are flying back to Dublin on February 01, 2024. If I am not mistaken we have just reached GOLD status as Etihad Guests.

Very unfriendly team. It was very difficult to get a cup of coffee. Legroom was extremely small. Old, dilapidated plane.

The seat was not functional. Very uncomfortable to sit upright for that many hours😢. There was no legroom. Can’t move the legs or the body. We should have the option to pick our seats. There was no need to call customer support team and have them pick and we pay for the premium seats. When I called the CST regarding the seats, their response is gaslighting. Total disappointment. We have paid to be tortured by Etihad Airlines.

Transit time could be 15 min longer atleast. It was right on the dot to boarding time. Giving minimal time to do shopping

I like the stripes, the more color the better I think you could even make more contrast with the stripes by filling in colors that create visual effect. The crew on both flights were polite well dressed, alert, good looking and very friendly. I never had a standing in line anywhere long for entering or exiting to my seat and it’s nice that people don’t bring too much luggage on the plane. The one thing I find is hard to manage is when a family or in general just being able to book a free seat if it is not for a dog, it shouldn’t be allowed. Since it is already very confined space on a flight overseas this can create slight conflict because there are sometimes free seats, which people then can freely use after cabin doors are shut. On the return flight, it was dark and by accident I stood on a paper bag with food in it that was placed on the floor in front of a seat next to me. I belong to the lady across the aisle and I felt terribly sorry once I found out there was still desired food in the paper bag. So I felt uncomfortable for getting into this situation. Otherwise I had a great time.

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

Crew and service was excellent. My seat was super small and cramped! No leg room

Staff was rude in business class. Luggage was damaged and nothing was done about it airlines.

We were helped whenever needed and had a pleasant flight.

Boarding is as always an issue. Slow and long boarding time.

Deplaning at Frankfurt required ck=limbing steep stairs with no provision for escalator or elevator.

Plane left 1 hour and 30 min late due to a faulty gate at the airport . they should have changed the gate immediately and minimize the delay. Due to this fact I lost my connection in Munich and ended up staying 12h in the airport . I got rebooked and for the troubles i got a 15 euro voucher witch is barely enough to buy a bottle of water in the airport . A bottle of water is 6 to 7 euros in the airport a sandwich is 12 to 20 euros . a sleep cabin is 17 to 20 an hour . their compensation is mediocre at least it has not changed the amount in the past 10 years , where the prices since then have . On top of this on my return they broke both of my check in bags another 500 USD damage

Another couple hrs delayed no compensation for the flight that was 11hrs delayed
