Similar to Hyd->Dubai this too was worst airlines. Bad seats, bad seating arrangement which created lot of confusion since family member were not given seat together. However most of them changed the seat and got with the family. Cheap tactics by Emirates.

The best ever, friendly and attentive cabin crew, amazing captains who utilised their expertise for less turbulence, just overall amazing

Overall I was quite pleased with the experience; the cleanliness; the polite and attentiveness of the cabin crew; and the delicious food options.

I would never have been able to make the transfer in time without asking for a wheelchair

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

Loved that I had an exit row seat, and there was no one else in the row! And again, I don' use on-line entertainment at all (I read or sleep) but I very much appreciate that I didn't hear anyone else's entertainment!

The entire crew was amazing. They went out of their way to make us enjoy a great travel experience.

Loved everything! This flight had premium economy and I didn't see an option to upgraded to premium economy OR buy premium economy tickets. How come?

Some Crew were distinguishably fake in their interactions with passengers.

We was missed the flight They doesn’t lest us fly next flight without payment They charge me 606 hundred dollars What is very unacceptable,our first fight ticket was almost 2000 dollars, again paid 700 it’s hurt … airlines need to do something please

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.

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.

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 was delayed which cause me to miss my connecting flight in AbuDhsbi airport.

Liked leg room Disliked unable to book to sit with my family on same flight without paying extra

It was a short flight, everything was good with it.

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

I meant this flight was not good, the one from Tirana to Frankfurt was better!

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

I wish seats were not reclinable. It's so claustrophobic when the person in front of you spends most of a nine hour flight leaned all the way back. The crew was really nice though and the dinner (red Thai curry) was pretty compelling.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

The boarding system was all bogus - employees at the boarding gate were not sound like proffesional or may be possibly rational

I got an email in the morning of the flight 1/7, from Kayak, that I was rebooked from UA 906 to LH 430. Nobody at Lufthansa ot United knew about this. I went to both counters. at the airport. Also, Cheap Flights, who I booked the ticket through, did not know. I ended up staying on the United flight. But this was very disturbing, since I got a very late notice that I was rebooked to an earlier flight, I hurried to the airport to find out after a lot of inquiring that this was a mistake. Not a good Kayak experience.

After living in Europe for five years and flying with Lufthansa and KLM airlines, I’ve realized that United Airlines is now a budget carrier. The flight attendant are not friendly. The seats are not comfortable. And everything comes at a cost. I will be flying with KLM and Skyteam like Delta to the US going forward no doubt. United Airlines is not what it once was:

We had a pretty good experience. Enjoyed both the flights. Crew was very good and helpful.

They issued seat assignments and sat my 2 year-old in the row behind me, separate from me and my daughter. Communication/ customer service was terrible. They told me to change it in London, then in London, they told me to talk to the cabin crew, then a supervisor came and stuck us in the back of the plane when we were supposed to be in row 25. Overall, they need to really work on their customer service. Additionally the food was terrible and they ran out of meals and didn’t have any kid options. To top it off there was no in-flight entertainment for the first hour of the trip.

We missed the connection because we had to wait for a shuttle from the plane to the Terminal. Also, we needed assistance and none was available.

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.

Checking in prior on line and wait time at Gatwick was terrible. I would rate a big fat ZERO.

There was a slight delay. Otherwise, everything else was satisfactory.

The company that I bought my tickets through, Cheapflightsfares, failed to provide my confirmation information in a timely manner, so I was unable to check on at the country and therefore unable to make my flight. As a matter of fact, I STILL have not received the confirmation. After having read more and more reviews about the company, Cheapflightsfares appears to have scammed hundreds of hopeful travelers out of thousands of dollars. Please look into this company and, for the sake of anyone planning their next trip, stop allowing them to do business through you.

I checked in to bags, one arrived one was delayed. I did not receive the bag for 4 days - arrived on Tuesday, received bag on Saturday!

It was ok. Our flight was delayed 2 hours, and then again on arrival. The explanation given felt feeble.

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.

Inflight Services are poor compared to other airlines. They do not offer even water during 15 hr flight. Food is little in portion and I had food poisoning after last meal ( rajma chawal)

Boarding at Mumbai airport was terrible, the staff had no idea how to handle it. It was chaos - and led to a delay

My seats that I paid for were changed last minute and I had to sit in uncomfortable chairs

This was a bery good experience as it was a newer plane . AI older plane bussiness class is bad .

What a pathetic plane it was. Entertainment system didn’t work. USB port was broken. There was a hole on top of folding serving table. Broken restrooms in the middle of flight.

Our seat monitor did not Not work either way going to Vietnam. I had a bulkhead seat with plenty of room, but with No monitor, it was a long flight with no movies. Fun was good, staff was Excellent.

I will never ever book air india in the future. I was with my family and at delhi airport I had to go through too with horrible experience. My 12 years daughter saud that she will never come bqck to india the way people treated us. There was no line for bags drop off since we checked online and print tag at their Kiosk as per email instruction. People working at the counter were so careless and rude. They were keep talking to each other than taking care the customers. I will not recommend anyone to fly via air india. I had horrible experience. Especially, the staff at checking counters was very very rude and careless. I have feeling if air india won't change the way they doing their operations they will out of business in a few years. Air hostes were not happy . I did not see a smile on anyone in the plane. I called twice for the assistance and no one showed up. I hope you will sene this to the Hire authority. I left a video with an another employee of air india who asked me about my experiences. I hope they will make some changes ASAP. Regars, Mohinder Kumar
