Limit the number of usage of wine or please arrange our seats. The passenger was drunk on this flight and not on Thiruvananthapuram to Abudhabi.

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

It was excellent service in the snow storm gives us hotel and transportation. It will be more better if u can add one more meal because it’s a long flight boring journey. If you give extra meal time passes faster and can enjoy the trip better

Business class ticket should include lounge access and seat selection. The food quality and varieties should be more. It was surpirise that no dessert was offered.

From the start of my vacation at Logan Airport, Boston it was chaotic. I'm praying my flight home is better .I'm grateful that we landed safe

I booked and paid for a Business Class seat for myself and my wife. 4 hours before the flight i get a call saying the plane they sent doesn't have the correct layout to accommodate all the business class seats they sold me 3 months earlier at a premium of $1500 a ticket. So they have to bump me from Business to Economy and will give me a $400 credit (total of $800 for both seats) that I could turn in at Abu Dahbi for $400 in US cash. They then promised a row that we could have to ourselves and the arm rests would go up so we could spread out for each of us. My wife was taken care of but I was put in the exit row with the flight attendents set as part of the three...and the arm rest did not go up. When we got to Abu Dahbi, they would not exchange our credit for cash as promised. Very disappointed they took my money 3 months ago and refused to reimburse for the change in seats or follow the promises made.

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

Wish the flight attendants were more attentive in serving food

Certainly! Here’s a more concise and refined version of your report, maintaining a polished and professional tone: --- 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.

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