The check-in and crew staff were wonderful. The food was reasonable. The online side Qatar was very poor. Seats were very tight and not very comfortable for a 14 hour flight!

The flight was operated by IndiGo and not Qatar, which is a budget airline from India. Nevertheless, the flight was uneventful.

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.

The Achilles heel of the experience with Qatar Airways is the Doha Airport, especially for travellers arriving into Doha and not transiting. This airport suffers from being ambitiously big and the immigration into Qatar being overly time taking. At the end of my particular flight in which my travel was ending in Doha, the plane parked at a very remote terminal, from where it took me 30 minutes to arrive just at the immigration counter, with fast paced walking and the time on a train inside the airport. Then, at the immigration counter it takes up to a minute or more to process each tourist visitor,due to time taking face and finger scanning processes and langugage barriers if there are questions or information to be exchanged verbally with the officers. If several planes have landed at the same time, it is not unusual that one has to wait 45 to 60 minutes in the immigration queue. In short, the frustration of arriving at Doha takes away all positive vibe of the airline, as the airline and the airport are heavily intertwined and are marketed together.

Liked some flight attendants. 1 was rude I'll not say her name I don't want to get her jn trouble on my flight back to Dallas from Doha. Very rude to some races of people clearly. She needs a better attitude and bedside manners. Asking her questions and she responds "WHAT" twice rudely like I was bothering her and "is it going to be cranberry or mango juice with an attitude".

Seats very small and unable to pre purchase internet or seat upgrades

The only thing that could have been better, is that the food trays get left way to long after a meal. We had a snack 8 hrs into the trip, and they left us with the boxes and cups for way too long. It is not fun being trapped in your seat unnecessarily

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

Did not like anything. Seats were crammed, leg space was minimal and food was terrible. This was the first time traveling overseas in American Airlines and was the worst experience ever. Have learned a lesson to never travel in American Airlines.

Overall good. Food choice in business class is a concern as same dishes on every flight for months. Crew is great and seats on this sector were fine . They need to have more variety in dining

I was not given basinett seat.The connecting flight was missed due to airline fault i was not accomodated for hotel.Drinks were normt served frewuently.Never travelling again on tirkish airlines.I always travel wiyh family by turkish airline but no more.zero stars

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.

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.

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.

Amazing trip! No delays, no broken or lost luggage, and amazing food.

Amazing! Big line at Check in was diminished in 10 minutes. Boarding was quick and efficient. Service and food great. Only minor point: seats could be a little broader and for me being small, something to put your feet on during the flight would be great.

Food wasn’t nice and doesn’t have halal option

No customer service. Non educated staff members with no will to support or service the passenger.

Boarding was much delayed, and there was no explanation ( obviously they were waiting for something or someone. ) Passengers were all crowded at the gate with anxiety. On the plane, the crew worked very hard on checking for safety and serving delicious food. They were polite and courteous.

All was fine , but air conditioning was not working on board properly so was very hot

The flight was ok, but the chargers did not work, and the speakers in the back of the cabin did not either. The seats are too small, and the food was terrible. However, I am writing because the crew was extremely rude, not only that, but they also kept the curtains closed, forgot to clear our trays, the bathrooms were filthy, and trash was piling up. Additionally, one of the attendants had her earbuds on while in the cabin. From the movement, it seemed like she was listening to music, so not even the safety aspect was there. My neighbor s English is not good and they were very dismissive of her. When we deplaned, the crew in the back was just chatting with one another, and the first class attendant was nice and said thank you. It is nice that the crew gets along so well, but they did not take care of the passengers at all. They rushed through all the services and otherwise did not go through the cabin to offer water or anything else. i had the feeling of being unwelcome at a party. I am not a grumpy traveller, but I thought you really needed to know. Thank you, Carin

The seat I was stuck in was so unimaginably uncomfortable. I have never had that tight of a seat in my 20 years of flying. Even budget airlines give you more space.

Flight was cancelled and rebooking was an hours long experience which required us to rent a cab, hotel room and fly the next day on a different airline with a much longer layover

Everything well done and customer oriented There entertainment system is difficult to navigate

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

They gave us chocolates twice (for whoever would like an extra chocolate - kids did!). I asked for an extra water, and I was given one. Crew was very friendly!

Check in could have been a little cheerful rather than dour

So poor I will endeavour to never fly with them again. Booked flight direct with Lufthansa, LHR to Leipzig, with stop in Frankfurt. Transfer in Frankfurt, via app and website was a '9min walk'...it, quite simply is not - it was a complete terminal change, with passport control & 2nd security check. No guidance provided by gate staff. Missed connection (despite agents at passport control granting line bypass and running for 750m). No assistance from gate agents at missed flight (along with approximately 15 other passengers that didn't make connection. Lufthansa Service Centre staff helpful - their manager was not, stated it was our fault for not leaving enough time to make transfer, revoked compensation....err, how are we supposed to know about construction, new security procedures, late gate changes??? Really??? We went were airline sent us, at pace, they messed up (twice on both legs of journey). Will avoid at all costs in future.

The flight was delayed but I was still able to board the connecting flight in Munich.

The real bathroom smelled horrible and it smelled in the real of the plane..
