One hour before landing was the most scary part of my life. The plane just dropped from the air . No explanation or apologies from the captain. Women and children screaming everywhere. Would like to know what happened

One hour before landing was the most scary part of my life. The plane just dropped from the air . No explanation or apologies from the captain. Women and children screaming everywhere. Would like to know what happened

My flight going to doha had economy seats that had a little more leg room. Coming back the leg room was not there. I'm 6'3" and my knees were against the chair in front of me. I couldn't slide my feet under the chair. The 15 hour flight felt like torture from the lack of sleep I was getting being so uncomfortable. Food and crew were great though.

It was excellent except for at the very end. I woke up about 1.5 hrs before touchdown and wanted to order food in the Business class. I was told they had shut down food service. It would have been good to get a heads up before they closed the service. Anna the air hostess was wonderful. She did get me 2 bowls of fruit and I was very appreciative of her. Wonderful human and a hostess.

Amazing airline accommodations. The cabins were so great. The food was very good and the flight attendants were so nice. Made a 15 hour flight seem easy.

I paid extra for seating when first booking flight to be in a comfortable economy seat They still changed it to a middle seat regardless. When I asked for it to be changed back to aisle, they could only give me one at the back of the plane in the least comfortable seats.

Same as already mentioned. This was more comforting as I got my aisle seat for my knee.

Seats very small and unable to pre purchase internet or seat upgrades

It was good no problems made it on time for the next flight overseas!

Boarding was orderly, staff at the counter were friendly and so as most of the staff in the flight. Room for some improvement in entertainment, but overall very good flight.

Sitting arrangement is very poor and for entertainment options for Bollywood fans , need to add more movies and Hindi TV shows . Bcz mostly Indian people are spend more money to fly with Qatar so for their better entertainments please add more good TV shows . Thank you

Good could be better. Crew is good but not great. Not much snack options for kids. Bathrooms were not cleaned on time

The crew were really bad mannered! And spoiled all my mood throughout the flight!

Limit the number of usage of wine or please arrange our seats. The passenger was drunk on this flight and not on Thiruvananthapuram to Abudhabi.

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.

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.

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

Nothing was good. Everything needs to improve. Everything was abysmal. Needs lots of improvement. The check-in and baggage drop at the New Delhi airport was manned by disrespectful people, horrible experience. We will never travel by Etihad ever again.
