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.

The crew could have been more friendly and could have offered to make the beds. Also, Ethiad should have more vegetarian food options.

The flight from Abu Dabhi to Bangalore was terrible. The plane was an order model with no onboard entertainment. The beverage selection were very limited.

Same problem place in the middle so small Im 1,85 m so not good 👍

Etihad seems to have a very strict luggage enforcement. I am a very light passenger compared to other passengers which are mainly heavier. I do not understood why airlines enforce the weight restriction so strictly. I was overweight luggage of 1.5kg, but am probably 10+kg lighter than the average passenger. Other airlines are far more accommodating. Poor customer service as far as I am concerned. If weight is such an important issue to an airline they should charge passengers by total amount of body weight plus luggage. To me just ridiculous.

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.

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

This flight was a dreamliner so I think the space was ok for the legs, but the option for food was again limited and the crew was same.

One thing is very important is you people not giving seat arrangement together to couple, senior citizen. You have to take care of senior citizen. Do not look about money. Money is not important everywhere. Make relationship strong is very very important. I like Etiyad air line out of all air line. Food was hot and delicious. Air hostess gave very good service, nice attitude, very good behaviour. I gave 10 out of 10 marks. Thanks Jivraj

It feels like the seat did not have any cushion just plywood. The seats are so compact that I could not even move at all and I am slim. Just imagine someone else. Singapore Air and Emirates are far far better than this. Do not even travel for free. For a 12 hour flight sitting on a plywood is horrible experience and on top of that the person at checking counter at NY was worst and rude. Plus they charge arms and leg for everything. I think they would also start charging for belts and oxygen also soon. First and last time flying with Ethiad.

It was just fine. The sirlines did live up fully to my expectation.

Super surprised with the entire experience. Business class is incredible. Flight attendants around the world could learn customer service from these people. Simply fabulous experience all the way around.

Pillow and blanket are dirty. My son got multiple bites during the flight

China eastern was fantastic. I had read so many bad reviews that had made me nervous. However, I found that the flight attendant’s, and customer service check in etc. etc. was excellent. I had no problems. I would fly with them again!

Excellent experience however older aeroplanes used by China Eastern Airlines.

Delay in off-boarding due to customs at SFO... pilot announcement should have come earlier so passengers don't clog aisles.

Good airline for the price. The Air stewardess are great, nothing is to much trouble. Will use again.

Flight was fine, however we were not able to check in online, this adds to travel stress. Luckily check-in at Heathrow was quick, but we did not get the seats we paid extra for. We paid for a window and 2 aisle seats from Shanghai to Tokyo leg, but they changed us to middle seats. Not good :(

Couldn’t fly since they wouldn’t issue a boarding ticket. Something to do with not taking the departing flight since it was cancelled due to weather. No notice or anything about the trip being invalid. The app made it seem like I was all good for it. Never trusting travel agency

2 hours delay on the 1st plane out of the day!!!!!
