On time and no hassle luggage policy (2 checked in and 1 cabin bag)

Unfortunately the flight was cancelled so I never got to go

The seats seemed smaller than other business class offerings. The entertainment menu was limited. Flight crew was good.

excellent, the staff was kind and the boarding process was with no issues or hassle

Old plane, old entertainment system. It wasn't working throughout the entire flight. I was offered to connect to their system via Wifi to watch on my phone. Crew wasn't very helpful except one lady who turned the experience around.

Crew Check-In – Kolkata (CCU) The crew handling check-in in Kolkata was outstanding—efficient, courteous, and highly organized. Flight Segment – CCU to Abu Dhabi (AUH) A standard flight overall. Notably, only one in-flight meal option—a vegetarian curry—was available, which seemed unsuitable for a red-eye journey. The crew offered no alternatives, which was unexpected. Flight Segment – Abu Dhabi to Rome (AUH-FCO) Comfort improved on this leg, but service quality was average, falling short of Etihad’s premium standards. Crew attention was heavily absorbed by a difficult couple in Row 15 (port side), resulting in disproportionate focus. It was concerning that a steward had to personally return to apologize, a task better suited for supervisory staff. This highlights a development opportunity for supervisors Anna and Quashim in managing guest escalation professionally.

Etihad flight sector is a local . .give the same quality upto destination

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

I travelled from Adu Dhabi to Melb; service was minimal at best, when I asked for a bottle of water but no meal I was told it was not available- it seemed a cup would do. The staff were un helpful & dismissive. We had a family near us who I never saw obtain any assistance from crew- they were simply avoided! Meal was simple and adequate no hot drinks were on offer until close to arriving, with a pseudo breakfast. Seats were tight despite obtaining extra leg room. I will not be flying with Etihad again and will not recommend them to family & friends.

The seat was not functional. Very uncomfortable to sit upright for that many hours😢. There was no legroom. Can’t move the legs or the body. We should have the option to pick our seats. There was no need to call customer support team and have them pick and we pay for the premium seats. When I called the CST regarding the seats, their response is gaslighting. Total disappointment. We have paid to be tortured by Etihad Airlines.
