It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I normally love Korean Air, but this trip was not great. We boarded the plan and were settling into our seats. My son and I use these leg swings and we used it on the trip over to Cambodia, but on the way back the flight attendant very rudely told us we could not use it and that it was against regulations. I asked to see the regulation, but never saw it. The food on this trip was horrible as well, Even my son's kids meal was disgusting so we didn't eat anything on the flight. Thankfully we brought snacks. Entertainment - what happened to the games?

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Not many people, so you can lay down on two seats

They did an excellent job helping me with a wheelchair. I couldn’t have asked for any better help.

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

I lost my lock from my luggage, I don’t know someone took something from my bag.

Except for the uncleaned tray, and the delay in serving food for our section (which may have been due to the location of our row) everything else was good. The crew were very professional and responded to our requests promptly throughout the flight. We as a family were not disappointed by Emirates.

It was great, a little more leg room would have been better particularly since we were in premium economy

The boarding process was smooth and the stewardesses were nice. Some delays with drinks at the end of the flight, but no issues.

Very uncomfortable aircraft. No free entertainment or drinks. Food okay. Won't fly with them again.

Comfort poor, little leg room, cabin temperature too hot. No free entertainment. No complementary drinks. Overal experience poor and would not travel with them again.

Thay crew was so nice.Air hostess il ham was so nice.my mom was little scray with airplan turbulence she help us alot.

Seat 💺 was all the way on last row. Food was okay .

Charged for internet that never really worked. The food selection was just ok.

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

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.

Great. Efficient boarding process with the face recognition. Plenty of cabin space for luggage.

The only problem I had was not being able to download my boarding passes prior to arriving at the airport. Everything else was perfect.

The food and service was great. You have to pay a lot for in flight Internet though which is lame.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

So so, crew was overly professional and lacks human touch. Equipment is very old, especially the HKG-PVG CX366 flight. That plane along with its decor must have twenty years of history, or at least I had that impression.

Crew was great. But a bit understaffed. The business class seat, etc were dated. But comfortable. Some legs had entertainment system from a decade ago. Selections were rather poor. Food was mediocre at best. Actually poor for business class standards. I liked the lounge in Hong Kong. Showers were great. Food was nice.

Everything was fine and I have no complaints or things to note.

The economy seats are much indeed roomier. Meals needs improvement.

flight delayed 45 mins - missed connection - 1 hr layover became 8 hr layover waiting for next flight -

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

My flight was with American Airlines 120. The flight was delayed 3 hours and I missed my connection. When I arrived in Doha, the AA staff told me to call an 800 number to rebook a different flight, which was unacceptable. Eventually a Qatar Air staff member helped rebook me on a flight to Manila, that was 12 hours later. They offered me a hotel and meal voucher which I declined, because I didn’t want to leave the airport. Long story short, I spent 12 hours in the Doha airport waiting for my next flight.

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.

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

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.

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.

All the crew members were too slow and rude. Most of the times the registers were empty, while hundreds of customers were waiting in line, and it was impossible to get a supervisor. Despite being in line on time, I missed my freight, plus a some customers who were ahead and behind me.

The crew were very hospitable and pleasant. The food was pretty good. Unfortunately, there was a flight delay of more than 2 hours. We're not sure why but it appeared to be outside the control of Turkish Airlines.

Bough tickets with luggage, but made me pay at Airport as well

The economy seat was so uncomfortable, had not enough leg room for 13 hours flight, front seat basket was broken and couldn’t hold anything, food quality was horrible( we got food poisoned ) we charged for logged which used to be free. We paid too much for this flight and very disappointed. Turkish air line better to make satisfy and respect people instead of find different way to scam people.

This is really the rating of two flights. JFK to IST then IST to NQZ. New York to Istanbul was good. Good crew and all positives. The flight to Astana was so bad that brought it all down. Crew was nonexistent above the minimum, seats were cramped, and it was hot on the plane. Turkish Airlines seems to be slipping down to US based carriers level.

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.

Everything was very good, except that the plane was an hour and a half late

flight with heavy turbulence old boeing 777 rest wasnt clean dashboard doesn’t work

Light and recline did not work on my seat. Very uncomfortable and could not read in the dark

Bad experience; they are not good anymore. They charge too much for luggage seat are so uncomfortable, Flight delays which may miss your next flight, they don’t care if you miss the flight or not. Zero customer services for front desk representatives Istanbul's airport I’m not using this airline any more.

I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant
