Sadly I couldn't get the food I requested as it was out. Also, if you don't want to be woken up make sure the crew knows it. My wife was woken on every service.

Sadly I couldn't get the food I requested as it was out. Also, if you don't want to be woken up make sure the crew knows it. My wife was woken on every service.

Three meals on a single flight is disgusting. Even if I reject them all, sleeping is impossible and all that food (especially wasted food) is just antithetical to a pleasant flight experience. People were chucking multiple abandoned trays on the floor in front of my seat.

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?

Issues: 1) the charging issue as described in my previous survey 2) when I requested diet coke during the breakfast time, it is not available. Why? I can't drink diet coke in the morning? 3) when I tried to transfer to this flight, its gate information was not available to me?

The lead business class attendant was excellent. Made a point of greeting you and knowing your name by the time you leave.

A lot of things Never flying with this airline again Had an emergency landing

Chicken pieces were too big with pasta. Need to be smaller.

Seats in the absolute back row of the plane even though we booked ages ago :( Crew was awesome though

Overall pretty good experience. It would be nice to have caught the attendants even they were flying down the aisle with snacks, and if they could cater to multiple dietary restrictions (bland and no lactose. The customer service chat is a bad experience), but otherwise no complaints.

I am Vegetarian also has Gluten free food. However they gave me chicken and fish which is gluten free, but i am a vegetrain and i requested crew Hindu meal vegetarian, they said they will come back. .but they never showed up even i asked 2nd time. They could have compensate. I also request airline industry to have another option Gluten Free for Vegetarin people as well. Because Vegetarin people will have gluen issue...

Just want to do a little more clean up so does not smell like urine.

it was a great experience as far as business class.. but I have had better meals and wine on other airlines.. that said.. the price was a great value for what I got in return.. crew made the difference.

Check in process at the kiosk, crew in flight and overall comfort was good. Food selection could have been better. Flight from Hong Kong to Los Angeles did not have any vegetarian main course option, it was either sea food or chicken. Being a vegetarian I could only eat yogurt and fruit. Most international flights have one vegetarian main course dish which I found missing in Cathay Pacific menu.

Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

My baggage is lost. Flight cancelled, Rebooked ticket through long routes. Mental stress, emotional hurt

The flight overall was good. The attendants did a good job except that 1 female had too much fragrance on. The other things that made the flight unpleasant were out of the airlines control.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I would love the entertainment center to be updated with more content. The flight to Doha had more options than the one to Miami

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

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.

I felt that when I was rerouted it should have been to business class.

The flight was smooth Thank God but the delays and changing gates for 3-4 times made me so tired of walking back and forth with heavy bags I thought I was going to pass out with heavy headaches but Thank God finally found the final gate and home safe. These delays happen anytime for important reasons so just be patient when you come across these situations.

Food is very turkish. No regard for other natinalities taste and preference. The entertainment can be improved- it was the same menu on 10/8/25 and 10/25/25. The boarding is the worst in the airline industry- I suggest you ask your staff to and watch how other airlines do it.

The best airline for international travel in terms of value you get in business class (service/cost)

I liked the overall flight experience. However, Turkish officials could do a better job at guiding non-Turkish speakers to their connecting flight gates in such a huge & vast airport.

Very small and cramped aisles and seats. Food was poor but the fresh hot roll and hummus was good. No cans of soda given but they had small bottles of water. Crew was nice and pleasant and kept bathroom clean.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

Small seat space for 13 hours flight, they charged for baggage , very bad quality of food,

I was sitting almost in the back, the seats are very tight and there’s no legroom, it’s uncomfortable for a long distance

Absolute worst airline. Charged us $720 to check 4 bags (2 of which were carry-on). Entertainment systems didnt work. And on a 12 hour flight they served 2 meals and never once came around outside of those 2 meals with a beverage or cup of water. Will never fly them again.

Took forever to board. They made announcements without the loudspeaker and since the waiting room was full of screaming kids, no one could hear what they were saying. The business class sleeper seats were designed for tall skinny people. When partially reclined there was nowhere to rest my feet because they did not reach the footrest. and when fully reclined there wasn't room at my sides for my arms. Definitely one of the worst sleeper seats I have ever had.

About an hour delay but we made it to Chicago. I feel that the smaller connecting flights are the ones that cause the delays on the bigger planes that fly international.

IndiGo is low cost and therefore no frills, but is always a pleasant experience. No mood lighting and fancy features but clean aircraft, professional crew and absolute value for money.

Very hard seats. No food service, even though price is not competitive.

Very hard seats for long flights. No food even on International flight. Won't fly Indigo again if I can help it.

Terrible experience at IST airport due to mismanagement by ground and wheelchair staff.

Some seats don’t recline. No USB port or power outlet, no inflight WIFI - not even for SMS/Messaging apps. Ontime performance was very good. They should have at least one crew member who speaks the local language, for flights like these.

Although we took the XL seats with more width, we found that you do not have a seat in front to stow your personal item, nor can you stretch your legs. This is not the best option for a comfortable seat. Boarding was timely but disorganized without any row based entry.

Not professional and didn’t know about double seat even when I paid for it and have a confirmation. Lack of comms between teams.

deboarding is very poor after landing it took around 45 minutes to come out.

My baggage bag got broken and only 3000 voucher was given for compensation

Crew members forgot to serve sandwiches after serving the coffee. Worst was the handling of bag. One of wheel was Broken making it useless. Though a complaint was registered and assured of compensation voucher equal to part cost of the new bag.
