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

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

Premium Economy is not worth the extra money you pay. You are neither economy nor business. The seat doesn’t recline enough to relax your legs. Maneuvering while seated is cumbersome. Don’t recommend Premium Economy at all.

Everything was great but the food portions and quality was awful

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

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

Boarding, seats, entertainment and service were all great. The food was great except for the fact that there were too many sweet items.

The service on board was excellent, the flight wasn’t overbooked and we departed and arrived on time.

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

The ground staff on Islamabad is horrible. The on board services are excellent.

Nothing, all that I know is that I will never travel with Emirates again Qatar is were I belong. You guys should send someone over to experience what true acomadation is, Emirates has the worst food that I ever eat on any airline ,even jetblue has better food and snacks that curry Indian garbage you guys serve just make people sick.

Poor. Seats uncomfortable. No leg room. Hot and humid the whole trip. Food and staffs were ok.

I purchased a one way business class ticket from Geneva to Miami but the check in agent said I had an economy ticket and later upgraded to business class. This was not the case, I had a single business class transaction. I was forced to pay for my second checked bag. I am unsure of why this happened. But I won’t use Kayak again for business class tickets.

The seats were so close together, when the man in front of me put his seat back, the screen in front of me was 9 inches from my face. There is no way to lean forward if I needed to pick something up. It was pretty uncomfortable for a ten hour flight. I was very surprised.

The whole experience was positive. Crew very friendly and helpful. Very greedy with pre-seat allocation. Web site too complicated

All the flight to USA were arranged to E terminal whereas from Dubrovnik arriving on Zurich is on A80, have to walk all the way from A to E, even need transfer bus , for short transfer time like in an hour, we have to work fast, as soon as arrived at E, it is about time to boarding, pretty tight schedule, I hope Zurich airport can make some rearrangement so that transfer people do not have to walk long way. For short transfer time people, such as 50 min, this is even impossible if still like this.

Swiss airline do not allow online check-in before 24 hrs, this is very inconvenient to us. I tried many ways such as booking code(6 numbers) or 13 booking numbers , neither of them work, Lufthansa is better which allow us to check in even before 30 hrs, so we can assign our seats( not many people want spend extra money to assign seats on top of airfare which is already spent.)

Clean, efficient and quick response time when we missed our connecting flight.

When I needed to get my bag off of the plane so that I could take a train because the connection was 4 hours later, they took 2 hours to take my bag off making me take the train and miss my flight simultaneously. The seat size on the plane is too small for an average aged woman let alone a middle-aged man. It's unacceptable and I will not fly Boeing again.

The flight was generally good but was delayed departure meant a very late arrival for a connecting flight.

The cushion of the seats are old and very thin. The food can be more tasty or come with salt packages

The seats were uncomfortable. The service was poor. We bought internet for my family and myself and it didn’t work. The charger for our phone didn’t work. The service seemed like they were tired and exhausted and seemed a bit upset. It was not a good flight. Our flight from miami to Qatar was great but from Qatar to Tokyo was simply awful

I was unable to pre purchase sear upgrades or internet. Their online site is not user friendly and poor. I felt singled out in customs. Seats are very small even for a small person.

I recently travelled in Business Class with Qatar Airways, and overall, it was a pleasant experience. The cabin crew stood out for their kindness and professionalism, making the journey truly comfortable. The food exceeded expectations and was exceptional in both quality and presentation. The boarding staff was courteous, though I would like to mention that the staff member responsible for checking tickets during boarding could benefit from additional training to be more welcoming. A warm and hospitable approach would enhance the passenger experience significantly. However, one aspect of the journey was particularly frustrating. The in-flight entertainment system was disappointing, as the headphones provided did not work at all due to a loose connection. This significantly impacted the experience, especially since the flight also lacked Wi-Fi service. Addressing these issues would greatly enhance the overall travel experience. Lastly, I would suggest implementing a section-wise boarding process to streamline the boarding experience and minimise potential challenges. I appreciate the efforts Qatar Airways puts into delivering high-quality service and hope to see these improvements implemented in the future.

My experience with Qatar airway was very unsatisfactory. They lost my child’s stroller and I was told they found it and will send it to the hotel which was a lie. I had to go back to the airport baggage claim and pick up myself after trying to contact them many times!. There was a lack professional and communication. I am very disappointed in Qatar airway and will not be recommending them to friends and family nor will I be flying with them in the future.

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

The overall flight experience between Doha and Kolkata was satisfactory. The staff onboard were notably engaged, responsive, and enthusiastic, providing a level of service that stood out, especially when compared to the less attentive crew on the earlier leg from Heathrow to Doha. Their eagerness to assist made the journey more pleasant. Additionally, the time spent at the Silver Lounge in Doha contributed positively to the experience. The lounge offered a comfortable and relaxing environment, with adequate amenities and attentive staff. Overall, both the flight and the lounge experience in Doha met expectations, making for a smooth and satisfactory travel experience.

There was frequent beverage ,meal and snack service. The crew was very hospitable and professional.

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

Do not overbook flights and kick out confirmed ticketed passengers :-(

Noice cancelling headphones would be better since it’s a crowded plane And kids behaviors are unavoidable

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.

Etihad seems to have a very strict luggage enforcement. I am a very light passenger compared to other passengers which are mainly heavier. I do not understood why airlines enforce the weight restriction so strictly. I was overweight luggage of 1.5kg, but am probably 10+kg lighter than the average passenger. Other airlines are far more accommodating. Poor customer service as far as I am concerned. If weight is such an important issue to an airline they should charge passengers by total amount of body weight plus luggage. To me just ridiculous.

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.

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.

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

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.

Needs better seat for business class. My seat was falling apart. Also no WiFi on that flight

In never flown this flight, because my flight coning from Barcelona was delayed.

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

The wheelchair service was good. Staff and crew were helpful/supportive. The business of 'being overbooked' ....."you may not be able to travel tonight/we may have to put you in Economy'" was rather unsettling. Even Economy Plus in a MIDDLE seat felt cramped. The seating and experience felt very basic even though I had struggled to pay for extra - Economy Plus.

Good crew and boarding process. Horrible food and one of the most uncomfortable aircraft seats I have ever sat in. The cabin temperature was warm which made it hard for my family to sleep.

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

The first class seats were unusable, mine at the end of the flight, my husband's in the middle of the flight, and the one next to me was unusable either, they had to move the person to another seat.

With three empty seats across the aisle from me I politely asked the crew if I could sit in one of those seats. They initially told me I couldn't do it for my safety. When I pressed them again they blamed the captain. So which was it? I didn't appreciate either nonsense explanation simply because they didn't want to honor my request.

Hand bag was taken to be checked in at boarding gate

Nice flight, attentive crew, soft landing by the Pilot,, comfortable seat.

Very quiet aircraft, business class was spacious and comfortable. Very pleased with the service.

Great room between the seats, food was excellent, very comfortable overall and could have stayed on the plane even longer

Business class seats were very dated on my plane. Very little storage, charging ports were not easily accessible, tv screen kept flopping away. Vegetarian food was disappointing: hardly any protein and severely under-seasoned. Crew was lovely.
