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)

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

The seats seemed smaller than other business class offerings. The entertainment menu was limited. Flight crew was good.

It was excellent service in the snow storm gives us hotel and transportation. It will be more better if u can add one more meal because it’s a long flight boring journey. If you give extra meal time passes faster and can enjoy the trip better

Food quality and varites were very minimum. Surprised to have no desserts. Business class tickets should have lounge access and seats selection. They should be allowed to board while people with wheel chair, secial assistance and family with childrem.

Dear Team, I purchased a full travel package that included 2 checked bags through you and JustFly. However, when I arrived at the airport, my ticket showed 0 checked bags. Since I was traveling internationally to India with 2 bags, It was a $200 per bag at the counter, which was extremely disappointing. For an international trip, why would I ever choose a no‑bag option for only $20–$30 less? This seems like an error in the booking process, and I am requesting clarification and a resolution. I have called JustFly and on phone for 1 hr :53 min and they couldn't help till I show some kind of proof etc which isn't possible but besides that love your service and using it for years !

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

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.

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

There was not any issues with the Etihad Airways. Staff was excellent and I love the variety of movies and games that they provided.

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

Very disappointing #1 - You have to pay extra to use the business lounge, or else you sit in the cold airport for 7 hours and fall sick #2 - Did an awful job with boarding, they turned on the "last call" notice on the monitor made the passengers come running to the gate, once the passengers came close the crew would tell them - hey we are not boarding yet, this included passengers with children also, this was happening all the time, it was pitiful to see #3 - Did not have the courtesy for the passengers in the business class, there is a reasons why people choose business class, because they need to get to work, that means sleep is very important for them, in the business class, the crew members would themselves cause so much noise by closing the door in a loud way, once the crew member does it then the other passengers are also doing it, #4 - the food did not smell good, #5 - The Abu Dhabi airport is small, so not a whole lot to do, especially when the layover is 7+ hours. #6 - Did not provide the slippers with pajamas, #7 - also the pajamas also I had to ask, only after asking it was provided. #8- Asked for an extra pillow because the pillow they provided was not tall enough, the crew member said there was no additional pillow and gave me something like a blanket, I tried my best to use that as a pillow, but my head kept on sliding and that messed up my sleep and did not get deep thorough sleep Overall the airlines did not have an understanding of how to care for the passengers, especially the business class ones. Overall it was a bad experience, I would much rather spend the money with Qatar airways, the experience with Qatar is so much better.
