I have flown with them two times. Each time the flight was delayed by several hours. Boarding is a cattle call. There are no groups and everyone is running as fast as possible to get on the plane. People in Eastern Europe don't know how to queue. I paid extra for Priority since it includes a seat selection, two carry-on items, and priority boarding. The agents boarding at CDG made no announcements about priority boarding and seemed annoyed when I tried to jump the line to use priority. By the time I made it on the plane, all of the passengers had put their items into the overheads and they were completely full. No one wants to put items underneath their seat so they put small purses and backpacks in the overhead bins. A flight attendant came through and made me put my small personal item in the overhead, so I wonder if they have some kind of policy about this.
