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.

no issues at all... Kudos to the food. This time was really really good

One of the vstewardeses wanted to bump me of the plane for absolutely nothing. There is CCTV in the plane ans everything can be verified. Very disappointing , you all will see, o other 5 years and the passangers who does not smile to flight attendent will be bumped off...

The worst airline. Cancelled flight 30 min before boarding and rebooked on flight after 3 days.

It was nice to be on a legacy airline, people try at least.

Mostly fine. Minor delays departing and arriving. Quite a cramped plane, not so much as regards legroom but very narrow seats. Quiet nice food. Non-working USB charger. Flight attendants were helpful but not particularly proactive — one had to work to get their attention (but all was fine once they notice you), very Dutch style:)

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

The food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

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.

The qatar airways flights were great, the code share with Indigo could have been a lot better. There is no option for web check in, there is not information on the tickets for the INDIGO PNR this caused a problem with security letting us into the airport. The indigo staff did not even want us to line up before they opened the counters. There is not option on the indigo flgith to request special meals.

Staff was helpful. Flight was on time. Overall excellent experience. Thank you will fly again.

Each and every requirement was nicely provided by all staff no very be happy

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.

COmpared to my experience in the business class of other airlines the food variety and offerings were meager. They did not have any cookies or crackers for snacking! They were unable to offer some other items. This has never been my experience in other airlines.

Just on time arrival and departure would make it great

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

I am writing to express my extreme dissatisfaction with the recent flight experience I had with your airline. This has been one of the worst travel experiences I have ever encountered, and I feel compelled to bring it to your attention. Firstly, I missed my flight due to what I perceive to be a lack of clear communication and coordination on the part of your staff. There was no remorse or apology from the airline's representatives, which further exacerbated the situation. As a result of missing my flight, I was subjected to a 24-hour delay at the airport, where I had to spend a significant amount of money to rent a hotel room and cover other incidental expenses. Additionally, since my baggage was already checked in from Tanzania to Turkey, I had to purchase essential items for the 24-hour period. What truly dismayed me, however, was the discourteous and unprofessional attitude of your staff. Their lack of empathy and understanding only added to the stress and inconvenience of the situation. I have been traveling abroad for over 20 years, and I can confidently say that this experience has been the worst I have ever encountered. As a result, I am compelled to reconsider ever using your airline again for future travel. I strongly urge you to address the issues I have raised and take immediate steps to rectify the situation. Additionally, I expect a formal apology and a refund for the expenses I incurred due to the airline's negligence.

I’m unclear why I had to pay extra for assigned seats as Turkish airlines did not honor the seating. We were placed across the aisle from each other on TK 34, and were seated behind one another on TK 694. Because my name was misspelled on e-ticket (Klawiter, instead of Klawitter) I could not log onto website to get the connection gate number in Istanbul. The monitors in the airport were a jumbled mess 1/2 Arabic and 1/2 English.

On line check in needs a lot of improvement. I tried and gave up.

The crew was excellent, but the flight was a little delayed and the temperature on the plane was too warm.

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.

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

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

Boarding was quick and efficient. Ground staff were pleasant and courteous. Food was tasty, portions were good for me. Food containers kept slipping on the tray. Tray would look better with an anti-skid tray mat. I had the bulkhead seat which was very uncomfortable for couple of reasons. Aircraft is designed with no throughput to move across aisle to aisle. Passengers kept jumping over my legs to get from one side to the other to use the toilet. Secondly I had a mother and 9 month baby next to me. Mom had to hold baby for 12 hours in her lap as he did not fit into the bassinet. Half the baby was on my lap during the flight. Aircraft temperature was very cold - light attendant said it was the central cooling and nothing could be done about it. Movie selection was very poor old and outdated.

Crew was good, boarding mediocre, food choices were limited, seating was not comfortable

Horrible experience. Nothing to give to kids to keep them entertained.

We were helped whenever needed and had a pleasant flight.

Always a pleasure to deal with United's helpful and knowledgeable staff

You only get a chocolate square and small bottle of water.!

1. Food provided was not per the selection. 2. Very old and outdated media infotainment and not much language oriented films 3. Better provide with a proper headset rather cheap in ear headphones.

Horrible they wouldn’t let my wife and daughter board the plane. They stated there was an issue with her visa when she clearly showed them how to look it up online. This resulted in her missing her flight and having to buy a different airline ticket for the same day in which clearly there was no problem.

Very very poor. Reliability is the main issue. The flight from Bangalore to Frankfurt was delayed by 8 hours and hence we couldn’t make the flight from Frankfurt to St. Louis ( which was later canceled by Lufthansa ) . Bangalore airport lounge 080 is EXCELLENT. The shower in the lounge is first class. Wished they had some extendable lounge chairs for sleeping for the weary passengers. FRANKFURT AIRPORT IS HORRIBLE! WILL NEVER EVER FLY IN OR OUT OF FRANKFURT. There is no jetways for the Lufthansa flight and the bus took so long to reach the next terminal. We had to clear immigration and security checks again and again though we are transit travelers.

United tried to bump me. We pay good money to get on the plane we are scheduled to ride in. To hell with United Airlines.

Gets the job done. Don’t look for comfort or service.

Rude staff and seats are only can accommodate small people. If you 6 feet and up be ready for struggle.
