Very bad service and food variety will never come back again

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

The flight from HYD to DOH was delayed by 3 hours and we missed the connection from DOH to MIA. We had to wait 24H more to get the MIA flight. It was a total disaster. If the flight crew had waited 1 more hour to accommodate their 3 hour delayed flight, we would not have lost a whole day !

Flight canceled by JetBlue for no reason. No good alternatives provided.

Very difficult to check in and almost missed flight. No room in seats and had a middle seat. I tried to create an account and check in before to change seat and unable to. I do not understand why I wasn’t on a Qatar flight from on Bengalore to Doha when they left at the same time. Disappointed in the Kayak booking process.

My journey with Qatar Airways from Ahmedabad to Jacksonville on 3rd February 2026 was truly exceptional. The entire experience reflected comfort, care, and world-class service. Complimentary high-quality Wi-Fi throughout the journey was a welcome luxury, especially on a long-haul flight. The vegetarian meals were thoughtfully prepared, delicious, and served with attention to detail, along with a fine selection of snacks and beverages. What truly elevated the experience was the cabin crew — graceful, courteous, and genuinely attentive, delivering outstanding hospitality at every step. This journey perfectly showcased the premium standard Qatar Airways is known for, and it left a lasting impression. I would gladly fly with them again.

First off, it wasn't clear that my first flight was to be operated by IndiGO. While the flight itself was fine, this meant that my whole initial check in where I would've properly verified my seating on my Qatar flight/requested an upgrade was impeded by the fact that I had to check in with IndiGO. They said I would separately have to go to Qatar counter to deal with second flight leg issues, which was impossible given how long the check in took/no time available to do so.

Impressive as always. It is the airline of my choice, The dessert on the 2nd flight DOH-IAH was somewhat dry (the cake with cream etc) Check-in and boarding experience was fantastic, with the exception of CCU airport where chk-in staff refused to help with aisle seats stating the flight was full and accommodations were beyond him. Once I boarded there were plenty of available aisles. I was disappointed that this could not be done by self during online chk-in nor at the airport. Nothing more to add. Overall a good experience, TY QTR

Good staff, good intent, decent entertainment. More seat space would always be of benefit

The staffs were very good and helpful especially since we were traveling with a toddler

The boarding process was unpleasant. We had hardly any checked baggage, but they insisted on weighing the cabin baggage. While the weight of our cabin bag was well within limit, it seemed petty! The food was pretty disgusting. I had such awful food on the way over, that I brought some snacks of my own for the flight back. Glad I did. Qatar was consistent in that food was just as terrible on the way back as it was on the way over. The flight attendants were super-nice, though. If I had an option I would not take Qatar Airways again.

The seats did not have foot rest. If there is no foot rest you can’t sleep.

Maybe some more information as to why the flight got delayed I understand may be tell your customers that missiles were fired at a specific airport wouldn't be reassuring to the customers and would cause mayhem but something like recent events have cause a delay on your flight or smth

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

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

Air India Express operates as a separate airline, so it says. Air India Express is a subsidiary of Air India and is part of the Tata Group, which acquired a 100% stake in the airline. (https://www.tata.com/business/air-india-express). Yet Air India express is not a member of Star Alliance, so Star Alliance gold members do not receive the benefits they would had they traveled on a mainline Air India flight. Even though it's a subsidiary of Air India, which is a Star Alliance airline. Very frustrating.

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.

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.
