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.

From all the segments I flew it was the only one I did not get the option to choose ni seat, I did not get the quality of seat I had paid for. Crew was nice, airplane was clean, but no food, only water and a small courtesy chocolate. Everything else you had to pay for.

Awful, the plane was on time but Ryan Air chose to use it for another flight that was running late to avoid the 3 hour penalty so our own flight was 1.5 hours late. This meant a 1 am scheduled landing became 2..30 and we missed our car hire which costs us an extra £300 to rebook - bloody shambles

Stuck on run way for 2 hours before takeoff - tractor breakdown

We had to wait 2,5 hours in the plane before take off!!!

Enough seat availability for us to move a little and so sit together - but the flight was half an hour late

On time departure; arrived early into Faro. Air Malta operating flight, crew friendly and efficient.

I didn't eat any food so can't comment on that. The prices on the plane are extortionate (as are all prices on planes). Everything else was seemless and a great experience

The flight was 1h delayed. There was a flight attendant making announcements in the cabin, but it was impossible to understand whether the information was important or not. (Although whatever she was saying, it was clearly meant to be communicated to the passengers.) From the way she spoke, it sounded like Spanish, but only thanks to catching one word out of every five or six — mumbled through her teeth — I realized she was actually speaking English. It was quite embarrassing

The table at my seat was dirty, the crew was nice, the boarding was swift. An average Ryanair experience but this time the plane was not properly cleaned between flights.

Ryanair was ok but the flight is delayed 2 hours! We dont know the reason if it was either Ryanaair or the Kos airport or Vienna Airport …

I got denied boarding bevause they said they "ran out of seats on a plane"
