Very bad service and food variety will never come back again

My baby was with me it was really good experience with emirates

Fantastic as ever. Great staff super catering and excellent service.

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

We had to deboard using stairs. Why didnt you have the aero-bridge?

Everything was superb, only bad point was that the fast track on London Heathrow arrivals was not handed out to me and I had to go back to the gate to collect it.

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

You can improve in many ways First the crew in general is good, but needs to work with passion to their works not like robots Second, collecting the ear headphones long time before landing is strange The crew should deal with the passengers with respect and descent way not like giving orders

From Chennai to abu dabhi Abudabhi to Chicago Both flights are good , good service too

Air hostesses were great. Food was good. Flat bed is not that flat or comfortable.

Seats were very comfortable and the staff too was very friendly.

Flight got canceled due to Middle East conflict. Just fly hasn’t refunded me the money

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.

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.

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.

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

When landing in Hyderabad, the pilot made a hard landing. Everyone in the plane were shocked. The captain landed the plane hard and felt as if we were going to be thrown out from our seats. It was surprising the captain didn't apologize or make an announcement about. Again a surprise no crew acknowledge this. This was an odd experience!

I appreciated a meal on the shorter flight. It was slightly delayed with no announcement but I was able to determine what was happening.

I don't think there were entertainment options (short flight) - which is why I gave the 'ok' sign. Didn't make a diff in my flight experience either way, however

Really old air craft, broken seats and tray tables. Entertainment screens don’t work. Charging ports didn’t work.

Poor, pilot flew as if he was in hurry and had to coverup for wasted time

seats were not comfortable, entertainment was not working and food could be much better, given the airline calls itself full service and india's flag carrier.

The planes did not have charging jacks for phones or lap tops and there are no monitors for movies. On the flight from Delhi to Hyderabad I was the last person in First asked for a meal choice and only one meal was available so I had no choice.

Other than the inflight video screen freezing for about four hours everything else was brilliant.

The flight was dirty. The screens were not working and people were restless. Food and staff was okay.

Booked thru Kayak -> Indian Eagle. One leg of flight was cancelled after check-in (CCU to Del). Rebooked thru Indian Eagle cancelled again and rebooked. Cancelled once more now scheduled for CCU-BOM-JFK on Jan 18th. Let's see if this gets cancelled again. Would not book any tickets thru India Eagle - they are just a ticketing intermediate and for questions they ask you to call Air India. They "request" booking but apparently I got bumped after ticket was confirmed. Much better to book directly with Air India - avoid Kayak and Indian Eagle. I paid for Travel insurance can't see it any more on Indian Eagle site to contact.
