Just overall a poor experience with little to justify the price of the ticket!

I am very satisfied for choosing that Airlines! It was my first time but the everything went smoothly! Thank you!

OK, would prefer some meat for dinner, not just pasta although was tasty. There was only one dish, no choices

Accommodate the passangers at the gates. They only allow groups 1-3 to sit near/at the gate. We had to wait 3 HRs an had to look for a seat far away from the gate. Other than that was like other Airports.

It was a great experience. The aircraft is a bit dated but other than that it was great.

Booked economy. Seat felt like it was a bit more roomy than my last trans Atlantic flights. I had a nice person sitting next to me. Everything was as good as it could be considering you are 35,000 feet up in the air and in a metal container. Beers, wine, food were all readily available. Plenty of movies and shows to watch. Friendly flight staff

We were delayed three hours from Montenegro to Vienna on our outbound flight and then rebooked an extra leg on our trip to the US. Our bags, which Austrian made us check in in Montenegro even though the flight was barely half full, didn't find us for ten days. Then, when we asked for compensation for the delay we were given the runaround that the flight originated outside of the EU. Next time we fly Turkish Air.

Most of the crew members were rude, flight arrived late and we missed our connecting flight, they damaged my friends suitcase so badly that two wheels had been destroyed.

Loved the courtesy and punctuality. Very professional and most importantly on time.

I paid for carry-on bag, but they did not let me take it on board, persuaded to check it in because the flight was full. I agreed to help them out, and they mixed up tag numbers and my bag got lost. I had very valuable things in there, and my whole vacation experience was ruined. I even asked the boarding assistant why the tag number was different from the assigned one, but they assured me it was alright and the bag will arrive to my destination. Nothing arrived of course. Incompetence of boarding assistants cost me the loss of all my things.
