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

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

It was great! Kept the time. Provided what was promised

It was mediocre. Honestly, the flight was late but that didn’t bother me as I had plenty of time. The only thing that bothered me is that the crew never asked to make the beds for us in business class. Maybe the crew was exhausted and that just didn’t occur to them.

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

One of your male flight attendant was pushy and a bit of a martinette. Completely unnecessary.

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.

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

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.

Transit time could be 15 min longer atleast. It was right on the dot to boarding time. Giving minimal time to do shopping
