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

The plane. Airbus A330-200. Comfortable for a 7-hour flight. Seats seemed to have more legroom. I was in row 17. Flight was operated by Delta but was better than expected.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

Put some new and several options for entertainment. Do not be rude to customers and avoid serving them an extra coke or something. We paid 1200 GBP for a return flight.. A noisy, crowded, rude and uncomfortable flight.

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

The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

The flight was delayed for 2 hrs. Because they didn’t have a crew to fly. And it is not a first time for klm to do that. Last time they cancelled my filght and rebooked me 3 days later. Not reliable airline

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

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.

Seats are fair enough for medium tall people. Good food all the trip. Fight attendances are warm

Between Air India and Qatar my luggage was lost for three days. I eventually found my own luggage location using the Apple Air Tag. Air India used a paper form to report my lost luggage. I could never get past getting past luggage personnel with my report number before they would hang up on me. Only after them specifically telling Air India at Chandigarh airport where my luggage was located which was right under their noses did they react. After three days I finally received my luggage. The Air India luggage folks didn’t seem proactive in finding the luggage’s rightful owner.

Besides the flight cancellation, everything else was prefect. Kudos to Malaysian Airlines.

For a short flight, Qatar Airways offers very good onboard service.

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

Not impressed. Only allowed one carry on on such a long flight.

To many ads. 3 or 4 between each movie. All repetitive, all related to Doha which I was just passing thru.

I had already opted for Vegan food before 2 months yet they say we have no record for it,

Overall good but staff in the place looked extremely tired after 8hrs in 14 hrs journey and then service was cut short and response time for calls increased in later part of flight. Food was ok not astonishing

Boarding process was terrible. Will not travel Qatar Airways if I had an alternative. The food was one of the worst, even for airline food.

Transit , Too long for terminal change, for a moment I thought Qatar airlines going to Los Angeles by bus. Please make transit convenient and quick.

Awful. They cancelled my seats and demanded $1360 to rebook me

I was flying with Turkish Airlines from Tashkent to Dallas and from Dallas to Tashkent. In both directions the flights were late. I missed my connecting flight from Istanbul to Dallas in Istanbul airport because of that. That led to a no show case with a rental company in Dallas and I lost 460 US dollars. On the way from Dallas to Tashkent with a layover in Istanbul the plane was also late and I almost missed my connecting flight to Tashkent. Then my bag did not arrive with the same plane and only on the next morning flight from Istanbul. I was about to leave Tashkent the same day to Astana in Kazakhstan and then from there for work in Saudi Arabia. Luckily I had an excess in time before the next flight and I manage to get my bag back. Otherwise I would have missed 3 flights automatically because I couldn't travel for work without my bag and all valuables in it. So, overall, very bad experience with Turkish Airlines. Will never use these airlines again.

Horrible customer service , employees are rude , angry and can’t speak any language other than Turkish well,

Terrible seats are very uncomfortable and narrow. Really hard time eating and painful buttons.. crew was very rud not allow anyone to stand not even to go to the toilets

Overall it was good, but the flight was long and crews on such long flights in my experience generally get more involved. They make more rounds with water and snacks and check on wellbeing of passengers. It was not an overnight flight, so the ‘night’ atmosphere in the cabin was not called for

Good experience with Turkish Airlines. We will be back with Turkish in the future and look forward to upgraded business class on the 777 beginning in 2025 and on the Airbus 350 now.

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.

Don’t use them on the IST-isb route, horrible service

Was not able to check in online, so had to stand in line for 90 minutes to get a boarding pass, and I had no luggage to check. Why not let people check in in advance on line? Or at a kiosk at the airport?

There was a Turkish Airlines employee sat in 16A in the row in front of us. We understood that she was a Turkish Airlines employee from her interaction with the cabin crew and the fact that she boarded business but was sitting in economy with us. What annoyed us was the extremely loud conversation she had for the majority of the 12 hour flight with two men, one of which was leaning over the chair in front of her. This was annoying as they were so loud that my wife and I could still hear them despite wearing our noise cancelling earphones. No intervention was taken by the cabin crew. Secondly, she ordered some extra meals from the crew, which we believe to have come from business class, for her male friends. Seeing this in economy is very disheartening. Lastly, one of her male friends pulled out an e-cigarette and was only mildly reprimanded by the cabin crew. Overall, we consider this behaviour completely inappropriate of a Turkish Airlines employee. Next time we will book with Emirites, I don’t think that their employees would be allowed to behave in this manner.

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.

Etihad flight sector is a local . .give the same quality upto destination

Long way to improve. Toilets not working. Bad handling when flight was canceled

Lovely crew - comfortable journey despite it being an older plane.

Good range of movies but lacking decent tv shows. Wifi was really expensive on this flight, considering flights under 7 hours have a $9.99 USD charge for streaming, to jump up to $24.99 for a 7 hour 40 flight seemed a little bit of a rip off. Staff are inattentive, and really need to improve on the customer experience. The new airport is fantastic, as is the new lounge, a huge upgrade from the old airport and lounge!

It has been a couple of years since I flew with Etihad last, after having a unpleasant experience with them coming out of the pandemic. I can say that the experience has uplifted, but I can’t really rate the service. At Barcelona airport the service was great, with their dedicated Etihad staff very helpful. The onboard experience wasn’t great, not very personalised and it really makes sense why Etihad doesn’t feature in the top 10 2023 Skytrax awards. The crew just seemed to be inattentive and almost absent from the cabin. I felt that I had to keep getting their attention. Even after I’d finished my meal, an hour went by before I had to call them to clear the tray/plate etc.

The staff was kind and polite, but it was very very hot and no ways to have some fresh air.it would be also be nice to have more time to sleep, since it was a night flight

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.

Eine Toilette der Business Class war gesperrt und somit nicht benutzbar.

I WOULD ADVISE NOT TO BOOK YOUR FLIGHT ON KAYAK. THEY SHOW BETTER FARES AND AFTER I BOOKED MINE, I FIND OUT THAT IT DID NOT INCLUDE LUGGAGE. i HAD TO PAY $800 TO CHECK IN MY BAGS.

It wasn't clear that there will be additional charge for checked in baggage. Very, very disappointed making me pay extra $75. Food was not tasty and not healthy. Lufthansa used to be good, not any more. Unfortunately has gone down big time and continues to go down.

Flight was cancelled. Rebooked after 5 hour delay. Pregnant daughter rebooked following day with 12 hour layover in Düsseldorf. However - I must applaud and praise the Business lounge hosts who were EXCEPTIONAL in trying to rebook and arranged for our daughter to standby for last flight of the day - which she made. The terminal B business lounge reception staff were AWESOME

Lufthansa has outsourced their ground crew to a company in Bengaluru. This company is really not dedicated to customer service. Very disappointed as this does not reflect Lufthansa’s service that I remember from before.

It was horrible!! The plane was old and outdated. The AC was not adjustable and got me and my daughter sick because we couldn’t redirect it away from us. Absolutely no leg space. The food was garbage. Horrific experience! Shame on Lufthansa to use such trash airplanes.

It was disappointing that I could not sit next to my wife but I was not allowed to pick my seat

The flight was delayed and I would have missed my connection so I had to be rerouted on a much earlier flight.

A very poor experience which is a surprise as Lufthansa has such a good reputation. Absolutely no leg room in economy - it was very very uncomfortable - the video/tv screen was not working, food was poor but that is standard for airline food. Flight attendants were generally nice and helpful. Pilots were reassuring.

The Business Class seating did not stack up to other airlines that we've experienced. There was no privacy and the seats in recline for sleeping were not well padded and comfortable. There was no mattress pad provided either. The crew was not as respectful and accommodating. We have no specific complaints regarding the crew except to say we've been treated noticeably better on other airlines, for example, British Airlines. Lastly, we were immensely disappointed when we got to the Denver airport as our flight was significantly delayed, granted, due to a lightning strike in a nearby airport, but what made this worse was our discovery that we could not use the United lounge for the 3 1/2 hour delay. We were told our Business Class tickets could only be used for outgoing overseas flights. This left us scrambling to eat the sad restaurant offers at the Denver airport. All in all, we would not book another Business Class flight on Lufthansa.

Loved the food (vegetarian in our case). Super pleasant. We're in our 60s/70s and not speedy anymore but I never felt rushed. Entertainment choices very current, personalized, and fun. Asked to change seats with a man who had paid for his seats as well but something had occurred in process so he was two rows away from his small daughter. Staff was very efficient at mediating the exchange and gave us a beautiful little travel pack as a gift to agree to it. The seats were comfortable but reclined a bit much for my comfort. I'm glad I'm not claustrophobic as the person in front of me reclined to the max and I felt very enclosed. Very efficient crew simultaneously as super pleasant.

All 4 flights were late. Plus delays for cleaning planes . On return baggage was not even on the plane arrived next day not received until two days later . Very poor experience.
