Airline reviews

The crew was very attentive and delivered great service unlike any other airline. It was our first time with Emirates. Our only critique is the food. Pasta pesto is not very common. Tomato sauce would’ve been more of a crowd pleaser. Beef curry sounds bad because curry can be very tough on the stomach. We were in row 26 and the pasta ran out, meaning no one wanted the beef which says something. The beef was just ok… The rest of the food was very good and generous. The plane speaker sound could be better. It was tough to understand announcements even with headphones. Although we did not need them this time due to the purpose of our trip, we were surprised that 2 checked bags were included. That’d be great for the future. It was unpleasant though that our personal items were weighed (we’ve never had another airline do this), especially when we didn’t have checked bags and almost had our carry-ons checked. Overall it was a good experience, but we wish the prices were friendlier for such a short distance (Miami > Colombia).

It was very exlent flight and thanks a lot kayak

Flight was cancelled without notification. Information on flight status was not available on Emirates's website.

I love to travel again and again in Emirates. Keep up the good work.

I liked the newer aircraft CRJ-550 since it had WIFI and the seats are more spacious.

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

Some Crew were distinguishably fake in their interactions with passengers.

Better entertainment; the lack of it made the very long flight even longer

POOR CREW BEHAVIOR. RESTRICTIONS ON FOOD. FEELS LIKE ECONOMY CLASS.

Food was not eadable. Testless and not apealing. order for indian vegitarian, recived spice less. combination of main course and side iteams are far away from traditonal food, serve less iteams. , but eadoble. Thanks

The crew were really bad mannered! And spoiled all my mood throughout the flight!

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.

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.

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

On this flight...fine. The one from India to Abu Dahbi, awful.

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.

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

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

Nothing was good. Everything needs to improve. Everything was abysmal. Needs lots of improvement. The check-in and baggage drop at the New Delhi airport was manned by disrespectful people, horrible experience. We will never travel by Etihad ever again.
