Very uncomfortable aircraft. No free entertainment or drinks. Food okay. Won't fly with them again.

Very uncomfortable aircraft. No free entertainment or drinks. Food okay. Won't fly with them again.

Excellent comfort and entertainment. Service poor..Food average with little choice.

Comfort poor, little leg room, cabin temperature too hot. No free entertainment. No complementary drinks. Overal experience poor and would not travel with them again.

Comfort good. Service as usual poor. Cabin temperature as usual too cold, about 15 degrees

Comfort and customer service from most if the crew was great. The crew reassigning passengers should consider the presence of infants when reassigning seats. Unfortunately a couple of oversized passengers were relocated next to us, making this segment a bit uncomfortable, as there was not only extra leg space required. I ended up swapping seats with my husband so our baby wouldn't be impacted. My husband travelled quite uncomfortable as the reassigned neighbour shoulder and arm ended up on my husband's seat

Boarding, seats, entertainment and service were all great. The food was great except for the fact that there were too many sweet items.

Emirates is always a pleasure to travel on. From the spectacular First and Business Class configurations of your big A380 and 777, to the Bar Lounge to, of course, your impecable on board flight attendance and their iconic uniform, now also even available for young girls. All the destinations that Emirates offers makes it an airline of choice many a time.

Boarding was a mess, no one managing the queues. I got my meal as the pilot announced starting commencing descent and basic drink not available. No air bridge so takes forever to deplane the A380 onto buses.

Bad Cancel the flight Came back to work only 3 days after Horrible Won’t help with hotel while we stock Horrible Don’t fly with them

Worst trip ever from the beginning to the end I will never travel with that airline again. I made a big mistake by not going with my regular schedule flight with Qatar airline. Even underpriced cheat me of my 134 dollars I paid for special seats and they kept my money and didn't pay the airline for the seats for me.

second leg was more comfortable. Customer service in Abu Dhabi is okay.

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.

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.

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

we were delayed from Athens to Abu Dhabi by an hour and a half, so I had trouble connecting the flight from there to Bali. It could have been done had they waited even 15 mins. There was another lady who was in the same boat. By the time we were half way across the terminal, they have actually already issued different flights for us to go Jakarta then to Bali. Not to mention the inconvenience of waiting over 4 hrs at the airport and the subsequent inconvenience, we did not arrive to Bali till after 800pm the next day, which means I paid for the hotel for nothing when I could have been there before noon the next day! There was little explanation. It was just as well I needed some assistance getting around, otherwise the 2 of us would have been completely lost! Not going to fly with them again!

Needs better seat for business class. My seat was falling apart. Also no WiFi on that flight

In never flown this flight, because my flight coning from Barcelona was delayed.

The flight was delayed which cause me to miss my connecting flight in AbuDhsbi airport.
