Practically everything went smoothly. There was no onboard service on our way to Paros, but they did serve a snack on the return flight. Don't know why, because there wasn't any turbulence on ATH-PAS. The only "complaint" we have is that we booked the ComfortFlex ticket, which allowed us to reserve up-front seats free of charge. The reservation was not available online, even though the plane was ATR 72-600, where they do allow seat reservations. Even though we checked in immediately when the check in opened, they only seats available were at the back.
