I staff or crew they were very friendly and humbly, they done theirs service very well, I appreciate them and thank you to the company or Qatar 🇶🇦 Government for providing as good service in their flight ,once again, thank you 😊 🙏 😀 😉 👍

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 flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

The crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.

Too many boarding protocols. Never experienced with other international flights.

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.

I would advice everybody not to fly by Indigo, no entertainment in flight, rude behavior of staff, worst experience of my life

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.

If you want to make money pls charge it in the ticket, Chennai check in crew simply forcing travelers make payment for unnecessary. Second, Chennai crew not even listening travelers request. Poor service and not sure you will improve with my feedback.

Lovely aircraft and I flight entertainment. Good leg room. Full flight crew struggled a bit

Overall mediocre experience. Check in was good. They're were discriminatory. They were not attentive, food choices were not vegetarian friendly. The food served was frozen.

1st time with. Etihad Airways and it was amazing from check in to crew. Great flight.

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

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.

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 member took too long time to take back leftover food plates from passenger seats. Food was nice.Easy excellent checking.Guy at checking counter was really kind and helpful.Made our checking very quickly. Leftover food should be taken back ASAP. Because in economy class passanger have narrow space . In the long journey like this, passanger have difficulties to sit with the plates.overall experience was good.

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

Everything is good and improved and needs to improve economy class seat more specious so long journey we can enjoy and it will be give more relaxable. Overall all services good and safely landed . I enjoyed my journey and all the cabin crew members services very well.

Dear Etihad Airways Customer Service, I hope this message finds you well. I am writing to express my deep disappointment with my recent flight experience on Etihad Airways, which took me from India to NYC via Abu Dhabi. My flight details are as follows: [Flight Number] on [Date]. My overall experience was marred by a series of significant issues that I believe warrant attention and improvement. These issues include: Bad Conditions of Washroom: The state of the washrooms on the flight was far from satisfactory. They were inadequately maintained and lacked the level of cleanliness one would expect during a long-haul journey. Seating Space and Comfort: The seating arrangement left much to be desired. The seats were cramped, uncomfortable, and the legroom was insufficient for such a long flight. The seats did not recline as expected, making the journey quite uncomfortable. Cabin Cleanliness: The cleanliness of the cabin, including seats and tray tables, was not up to par. The lack of cleanliness impacted the overall comfort and satisfaction of passengers. Excessive Noise: The flight was notably noisy, with disturbances and loud noises making it difficult to rest or concentrate. The noise levels were considerably disruptive. Food and Catering: The quality and variety of meals served on the flight left much to be desired. Furthermore, there were issues with accommodating dietary restrictions, which is crucial for passenger satisfaction. Hygiene and Sanitary Facilities: The condition of the restrooms was subpar, and essential hygiene supplies were not adequately provided. This falls short of expectations for a long-haul journey. Overall Experience: Regrettably, the combination of these issues significantly affected my overall experience during this long flight, making it far from the comfortable and enjoyable journey I had anticipated. I understand that maintaining high standards on long-haul flights can be challenging, but I believe it's vital to bring these concerns to your attention in the hope that they can be addressed and improved upon in the future. As a loyal Etihad Airways customer, I had higher expectations for my journey. I kindly request that you take these issues into consideration and work towards enhancing the overall passenger experience on similar routes. Your attention to these matters is greatly appreciated. Thank you for your time and understanding.

The legs room was not enough at all. The seats are not comfortable enough for long journey but other than that it was very good
