We loved flying with Emirates in business class, the staff were fabulous, going above & beyond

Delayed and missed connecting flight. But Emirates took care until next day flight. Thank you

They should resume the fast track for business / first class passengers

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!

Good food, real silverware, polite staff, smooth landing, charging plugs, good entertainment options.

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?

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

Indigo airlines is terrible. Staff is awful and so disorganized. They are so rude and unhelpful. I will never travel on Indigo airlines again!!!!!

Awful plane to Tashkent. Not even possible to sleep. In business class does not even recline fully

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

I had a terrible experience checking in at the airport for my flight. I booked my ticket initially through Kayak while it was promoted as a ticket that offers a carry on and 2 suit cases. (I have a screen shot as a proof of it) I selected it to buy three tickets and paid online. Couple of minutes later airfare assist which is the OTA offering the ticket called me saying My card declined. So I used a different card that went through. I was surprised that they increased the price ticket by a $167. They said the ticket no longer exists and because my card declined I had to buy a new one. So I did. The day my family and I were traveling I could not check in and when I went to the airport I was shocked to be told my ticket had no bags allowed and must pay $200 per bag for three people 6 bags mean I have to pay $1200. I called the travel agency as I feel I was scammed the confirmation didn’t say anything about the bags and they never told me the new ticket doesn’t not include any bag so they changed it after I selected it on your app without informing me. Very sneaky. The travel agency said they will reimburse me only for one bag person. Which means I still paid $600 I still feel very disappointed to pay such an expense. I have always used Kayak to buy my flight tickets and telling everyone how good your rates and app are however after this I feel I was mislead and paid more for something I should not have to. You allowing such an agency on your platform will surely hurt your reputation and level of integrity. I have all the proofs from the screen shot to the confirmation email from them, the or email offering to reimburse o e bag per person and the $1200 bag fees receipts that I paid on the desk. I must be refund the full amount and I look forward to your response.

The food could be better. Toilets were smelly all along

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

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.

Crew was very courteous, friendly and professional. Caring and attentive.

Very good experience. All of the details made this experience very positive.

The crew was exceptionally polite and caring. The plane was comfortable. Great experience. Will fly more on Air India because of this experience.

The flight attendants were rude in the DEL to FRA flight. The transfer between the two flights at Frankfurt International Airport was an unpleasant experience. The airplane was never parked at the terminal, but was deboarded instead on the tarmac itself. For those passengers in need of a wheelchair, it was a nightmare to come down the stairs and then rush across the airport to catch the connecting flight from FRA to IAH. Upon arriving at IAH, it was informed that the luggage had not arrived. Would make it a point never to travel with Lufthansa again.

Entertainment system is old, touch screen isn’t working properly. New movies should be added atleast once a month Should provide toothbrush and toothpaste at least when asked.

The experience was great. A330 needs an upgrade between RDU and FRA and vice-versa.

Flight ride was good, crew members were great however they need to hire some better food caterer.

You gave me a “Never fly Lufthansa” experience for life. You charged me $1760 for reinstating my ticket on a cancelled flight. Service at the airport was terrible. I’m convinced that I should never fly Lufthansa.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

The flight to Frankfurt was delayed. Consequently the connecting flight to Seattle could not be boarded. Lufthansa accommodated in a Cattle Class Flight where the Seats and foods were horrible. I had only Hobson’s Choice and boarded the flight and reached Seattle 3hours later than my scheduled arrival.

Overall it was good. But air planes should be upgraded.

Bad seats. Broken entertainment system. Charging port not working. Seats were broken worn out. Crew was amazing. They helped as much as they could.

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.
