I have my first FR sector in about 10 years coming up next month, SKG-ATH. I have paid about €20 for the fare and don't care where I sit for this 50-minute, "up-beer-down" flight.

My question is about luggage. I am spending a week in Greece and will be carrying a standard small roll-a-board. Is this included, or am I limited to the stardard "personal item", i.e. under-seat size?
