Everything was great but the food portions and quality was awful

no problem with Emirates it was the underpricer subcontractor Who was ridiculous

Good flight overall. Good options of food on NY-Dubai-Mumbai leg. Not that good reversing back. The flight crew is courteous and professional as always. The seating was much more comfortable going into Mumbai than coming back. Cheers!

Emeritus is ***** Fly dubai is 0 we need better service for Fly Dubai

Flight was on time. Seats (economy) were very comfortable and food was excellent. The bad thing was that after landing it took an hour to reach arrivals. We had to wait 15mins to get off the plane and then had to board a bus which moved very slowly and took almost 30 minutes.

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

Better boarding process at Hyderabad airport Better time management by air hostesses in providing the meals

The flight was nice and on time. The comfort can be slightly better in business class

Okish. But for £550 , I’d have preferred a better experience

The flight experience was good, but connection time was cut shorted because of delayed start.. it would have been helpful if the flight showed which gate/terminal we need to go for connecting flight and flight timing was less than 30 minutes to connect which made ourselves stressful to catch next flight 😔

The flight gate was changed and all the pessengers were waiting at the gate #2 for boarding, There were 4 (four) employees standing at the boarding desk and no one ever said anything about the gate changed. Finaly when I noticed an employee was removing the boarding zone signs, it surprised me something is not right, so I went and ask that employee what happned - she said the gate has been changed. So, i questioned again which gate it would be, she told me gate #5. I look for Gate 5 - which was down stairs. When I went to gate 5 - no body was at that gate which depress me a lot because it was already a bording time pass. Later I checked on the departure screen for my flight - it was gate #1, so I had to go back again upstairs in hurry as the boarding time already pass. They never anounced or telling customer anything at the original boarding gate - WHICH WAS TOTALY STUPID. I am 77 yrs old and what they the employees and the managers care about) care about how I can handle all this going back and forth. Air India is just advertising they are getting bigger but their services are just BOGUS and I don't expect it would be any better. They are getting worst and worst than they use to be.

It was just like any other budget airline in India—nothing extraordinary. The check-in at CCU was surprisingly smooth and effortless, as expected after online check-in. But BOM? They had me join the regular check-in queue, while six Bag-Drop counters were busy doing the same thing. Makes you wonder how Vistara plans to promote web check-in if passengers end up in line anyway.

Flight was delayed more than 18 hours, checked in bag damaged, no accountability from vistara ground staff. Worst experience. Shall compensate all the charges with double Ticket refund

The flight was an hour late. There were no gate announcements or displays. After getting on the plane, there was a further delay without any explanation.

The flight was on time. I upgraded to Premium Economy and it was comfortable. The food was very good. Staff were courteous.

Flight was delayed but no announcements were made. Till the boarding it was still showing original schedule time at the monitor and also on your mobile app. It left the gate half hour later than scheduled.

It’s really very nice experience with very nice behaviour respected crews n all Vistara members thankyou so much Vistara to give us humble hospitality

My wife with 5 month son were traveling. No proper support was provided for luggage handling. Although it was requested in prior. My wife sole manage everything and was not as expected.

This was an old 320 without a screen or USB charging port even in the business class. The food could have been better.

a real good flying experince. Everything was excellent right from check-in to baggage collection at destination.

The Achilles heel of the experience with Qatar Airways is the Doha Airport, especially for travellers arriving into Doha and not transiting. This airport suffers from being ambitiously big and the immigration into Qatar being overly time taking. At the end of my particular flight in which my travel was ending in Doha, the plane parked at a very remote terminal, from where it took me 30 minutes to arrive just at the immigration counter, with fast paced walking and the time on a train inside the airport. Then, at the immigration counter it takes up to a minute or more to process each tourist visitor,due to time taking face and finger scanning processes and langugage barriers if there are questions or information to be exchanged verbally with the officers. If several planes have landed at the same time, it is not unusual that one has to wait 45 to 60 minutes in the immigration queue. In short, the frustration of arriving at Doha takes away all positive vibe of the airline, as the airline and the airport are heavily intertwined and are marketed together.

This trip was the most comfortable one I have ever experienced, the team was excellent and very helpful. I am so glad I picked Qatar Airways.

They didn't board by zones and it was a free for all. The 16 hour flight was the most excruciating experience of my life and the seats were TINY... with no leg space and my feet were swollen immediately. The food was so bad it was inedible.

Qatar Airways did a very good job. Flights were slightly delayed with boarding but pilots made up time by arrival. The food was OK, no better or worse than other airlines. Although it would be nice to have three meals during 16 hours flight instead of two.

The space was tight, hardly any leg room and the crew surprisingly were busy and did not take the time to attend to passengers, felt rushed. There was a delay for check in since the systems were down the airport staffs were accommodating

I was denied lounge facility at airport. Explanation was not satisfactory.

Moved seats, didn't accommodate requests to change seats even though other seats were available.

Being a QR Platinum member traveling in business class, I expected the staff to be more courteous. Unfortunately, the lady staff was rude attending business class 1K side.

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

It was a long flight but overall a good one. The one thing that I would comment on is that there is a real problem with disposable plastic products when it comes to the meal service. It would be great for Qatar Airways to find ways to make its meal service more circular and reduce the immense amount of waste.

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 my seats, I was cramped, had no overhead bin space, freezing as the flight had no temperature controls, the food was awful and served cold, when asked for snacks was told to wait and then never received any. I booked this flight as a partner through American Airlines but will avoid in the future.

Took a long time for boarding. The flight was comfortable.

Flight was delayed due to slow boarding process by etihad. Update food options and movies as well.

Should have had business class line in immigration. Food quality suboptimal

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

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

Boarding was efficient, had to check in cabin luggage. Seats were narrow, food was more in quantity, received cabin luggage on the luggage belt which was fine.

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

I did not have a good experience in both flights of Etihad. First of all, when I was booking the flight, there were two options. The first option was a cheaper flight with longer layover (9 hrs), or a more expensive flight with shorter layover (2 hrs). I booked the expensive flight with shorter layover because I wanted a more comfortable trip. A few days before the trip, Etihad informed me that the departure time of my first flight will change 7 hours earlier, leading to an 9 hour layover, without giving me another option nor reimbursing me for the extra cost. They didn’t even send me an apologetic email for this change. Regarding the flight experience, I would rate it as mediocre. This is mostly because the pilots of both flights did their best to give us the worst approach to airports that I have ever experienced. In the case of the first flight they had to aboard the landing and took off again right before touching the landing strip. The captain said that it was due to wind conditions but the second time the pilot followed the same direction as the first time to land the plane.

Why should I rate entertainment if I’ve not used? You don’t have NA - Not Applicable option.

my experience with kayak was terrible. Team kayak just left me with a booking and limbo and preffered not to contact me.. Instead when I contacted the team they said the booking is cancelled. Seriously 5 days after booking u were waiting of my call to inform me of the incompetence of the team. This will be taken up with higher authorities

only passenger seats are too much narrow. It’s not comfortable otherwise it’s good. Seats are very important because it’s main in Travel

Miss my flight from delhi to amritsar due to lock the luggage door of airplane.and there was no more flight even for next days and they not refund the fare. I took bus grom delhi.. bad experiance.

very run down aircraft. seat tilted. the mobile / magazine holder was broken. The entertainment screen was not working. The crew was good, polite and helpful

Boarding was through bus even though aerobridges were empty. Major mess

Food is good, staff is good... Wi-fi quality is poor, disembarkment after landing is atrocious.

Flight crew was lovely. Bathrooms should have been cleaner. The handsets in business class for watching the entertainment are horrible. Very difficult to figure out which buttons are for what. I managed to get the flight maps on my screen but it wasn't easy. Never got anything else up.

Uneventful trip. Good flight crew. Food could have been better and a bit more of it. Cabin cleanliness was ok.

Extremely bad experience compared to Vistara. No priority in check in, no priority for boarding. No upgrade. Seat selection is paid. Curtains were dirty. Demo bag was dirty. Warmth of the crew was missing.
