Fortunately, cabin crew member was kind enough to give me a regular Hindu veggie meal rather than my pre-selected Vegetarian Jain meal (VJML) - DO NOT CHOOSE VJML on Qatar, unless you wanna faint from the horrible food! The tray was dirty! Co-passengers in the row behind me were also complaining The audio lead of my headphone would not go into the outlet in the seat armrest! So I had to use audio from neighboring (empty) seat and sync it with video from screen for my seat. What a pain!"
Pros: "Comfort of the seat/bed"
Cons: "The passenger sitting next to me was really sick due to flu. When i explained the situation and asked for masks to the attendant, you guys did not have even one. I was disappointed with that. I think the flight should have some for these kinds of situation so that other passengers can protect themselves. Thanks."
Pros: "The food was good. The legroom was enjoyable."
Cons: "I checked two bags and had them marked 'fragile', as I had valuables in there that I packed securely. When I retrieved the bags on the carousel, the fragile sticker was mangled, and both items from both bags were broken. Pieces of art I can not replace. Also, it took over 30 minutes upon multiple requests for the attendant to acknowledge my need for assistance."

Cons: "Nothing to complain about in the entire process from ticketing through flight and disembarkment"
Pros: "Checkin was really quick, needed to have some facilities for the passengers who have more than 8hrs layover."

Pros: "Food was great, good selection of entertaiment and movies, seat comfortable (even for economy class). Very friendly flight attendants. This was my first flight with Qatar and I'm now a big fan"
Pros: "Liked the raw vegetarian meal as it was perfectly plain. Attendants also very solicitous and went up and down several times with water after the meal."
Cons: "Seats are small and huge line for the toilet, but that is the nature of the plane and not Qatar's problem. Boarding was only good because passengers did not cooperate adn stood up when they were asked repeatedly not to."
Pros: "Everything is fine and have a wonderful time"
Pros: "The crew on the flight was excellent. They'll bring you pretty much anything reasonable you ask for. In flight entertainment options were many. I don't eat a lot of airline food, but the meals exceeded my expectations."
Cons: "I am quite tall (6'5"/1.92m), the in flight comfort was brutal. It'll take my knees a week or two to forget the constant jamming from the seat in front of me. Otherwise, on boarding was well organized, but very slow. Sound quality on provided headphones was very poor."
Pros: "The staff was friendly throughout and boarding was quick. There were no delays in taking off. They had also helped organize a hotel for the long layover including meal vouchers, visa, and return transfers."

Cons: "Tiny seat spaces"
Pros: "Qatar Airways is a nice airline and it's obvious they work on making your flight a pleasant experience with a lot of food, entertainment, etc"
Cons: "My flight was delayed 4 hours upon initially arriving to the airport. While it was important for me to be there when I found out this information because I needed to reschedule my connecting flightso due to the delay, this should not be required. Qatar Airways, knew the flight was going to be delayed at least 10 hours before they announced it. They should have already began the process of rescheduling connecting flights and figuring out problems before passengers arrive to the airport. I probably spent 45 minutes at the ticket counter working things out."
Pros: "upgrade flight"
Pros: "Everything was good."
Pros: "We missed the connection because the Istanbul airport is a silent airport and no announcement were made for boarding."

As a pilot, i can tell you this can be avoided. Some of the crew were not friendly. Old movie library."
Cons: "New and updated plane, especially business class, more trained crew, seats that work and function normally, better and more food, served a light breakfast on an 8 hr flight. Updated movie library."
Cons: "All the staff at the boarding part seem like they unorganized anything. They let all business passengers got it first but they didn’t open the gate door untill all passengers came through.

We called the stewerd and advised him of our observation and he promised to check with his supervisors; he came back and confirmed that all is under control. Arrived Bordeaux and the luggage didn’t. It took two days to get the suitcase and it took hours of follow up and the airport agent kept giving false excuses. At the end we drove to the airport and picked it up ourselves. Of course at the airport we listened to more trash."
Pros: "Getting Home"

I told them no need for their report but they told me that I may not travel and the male misbehaved againest my wife when she told him that no need for their medical assistant and he replied this is not your country. They sqwezed us at the last minute and my remaining family at the plane and they told me that I am not authorized to travel with my wife and small child. We are total of 9 passingers.

Pros: "The entire inflight experience was great from start to finish."

The man helping me lied to my face and told me that he could not make the change because the flight was full. when I got on the plane, there were over two dozen empty seats. It was very clear that he just did not want to invest the few seconds it would take to address my concern, or give me a credible reason why he could not make the change."
Pros: "The in-flight entertainment was above average. The in-flight crew was fine, although not particularly gracious or kind."
Cons: "The on-ground customer service in Istanbul was the worst experience I have ever had with humans in my whole life. They were unhelpful, rude, blatantly ignored people, dismissive, walked away from customers when they didn't want to deal with them, did not do anything to keep order when people were cutting in line after people were waiting for 4+ hours. I will avoid flying Turkish Airlines as best I can."
Pros: "Everything, fast boarding, good experience overall, turkish airline provides good services for very affordable price, i am pleased"

Pros: "Flights left on time. Boarding was good."
Cons: "It was blazing hot on every flight. Several guests complained yet the staff kept saying it was cool enough and would not turn it cooler.

Cons: "Nothing to knock down"
