Overall it was a very good experience. Boarding was efficient and well organized. The cabin crew were excellent. The meals were tasty and quite filling. The warm bread rolls were a nice touch. Seats were comfortable even if they were a little narrow. Entertainment selection was excellent.

The business class experience was awesome - I will be using QATAR airways again and it'll be business class again - appreciate the privileges afforded to the business class clients - thank you.

The 2nd flight from Doha to Mumbai was not of international level expected while booking with Qatar

Better service is needed. I booked for Qatar but I was switched to American way after I bought my tickets.

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.

Terrible airlines - suffered entire flight due to food poisoning from stale food

need to improve management and air hostess services. Rest of it’s OK.

Check-in staff were not very pleasing and sounded to be rude, even though I hold a platinum membership. The aircraft is brand new and good. As it's a short flight no other comments.

I liked the food and services provided. I think the seating should be updated cause it’s to congested for economic class.

I really did like the food and beverage and crew was really good!

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

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.

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

Food was very good. Again tray could use a non-skid mat. I had a regular seat - comfortable - able to sleep undisturbed. Boarding was uneventful.

Crew did not cooperate… I just asked water twice for one crew member and she didn’t get anything.. and when I asked other crew member he gave me water and he was not respectful.. I kept Hindu non veg meal chicken .. when I get my turn chicken was not provided and then they gave me veg paneer and green peas curry which I don’t like..

Sits are very uncomfortable Don’t feel like to travel in Etihad. It was 1st time we traveled in Etihad now we decided we don’t want to travel in Etihad.

Sits are very uncomfortable and food quality should be improved. Alcohol you have to ask and wait for more then 1/2 hrs. Don’t feel like to travel in Etihad. It was 1st time we traveled in Etihad now we decided we don’t want to travel in Etihad.

Food and beverage service have rooms for improvement .there were no entertainment facilities available
