More facilities to transport to the gates......felt too much walking distance

Not impressed. Only allowed one carry on on such a long flight.

I liked the overall service and comfort. The only annoying thing was paying for excess baggage at the airport. They have limited options and they don't take all cards.

Asian Veng meal have Non Veg items which is not ok. Pure veg meals option are too less and they have inclusion of Vedgan and Lactos etc... which is taste less

The plane from Dublin to Doha was quite comfortable. I was in economy and the seats and rows were very tight. The man in front of me reclined his seat and it made my screen incredibly close to my face and I wasn’t able to take my tray down and my knees were pressed against the seat. I had to ask three times for him to pull his seat up but in his defence he hadn’t even reclined it far, the rows were just too close. I had a pain in my side by the end of the flight from the chairs which were quite worn and not very padded or supportive. It was a significantly inferior plane to the plane from Doha to Sydney and vice versa.

You're like a poor man's Emirates Airlines. The Asian vegetarian food was awful. The entertainment selection was very limited and not contemporary at all. The seats were cramped. There was no plug for charging my phone (I refuse to plug into a USB port - A security risk). The plane itself was aged.

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

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

Good and comfortable flight Helpful crew Decent food and drinks

food in Qatar was terrible. I had ordered asian vegetarian meal but the food lacked any flavor. Choices of entertainment was also very limited. emirates is way better in terms of food and entertainment.

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

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!

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.

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

1.Aircraft Comfort: The aircraft type was quite small with non-reclining, cramped seats that significantly lacked comfort. 2.In-flight Entertainment: There was no provision of in-flight entertainment screens or Wi-Fi for the majority of the flight. 3.Boarding Process at New Abu Dhabi Airport: Despite the move to a new airport, which promised enhanced experiences, the use of buses instead of jet bridges did not meet expectations, causing inconvenience. 4.Gate Change Communication: A last-minute gate change was poorly communicated, resulting in a long and difficult walk.

Ripped off and broken seats in Business class. Seats stink and need to request the staff for additional bedsheets. Crew if very friendly though

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.

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

Everything was great. Cabin Crew was awesome and very helpful. Thank you so much.
