Well the proposed service to Crotone, if it ever happens, looks like one I wouldn't touch with a barge pole.
FlyServus (paper airline) says flights operated by Common Sky. But Common Sky doesn't operate Boeing B735s. They appear to have some tie up with AirX Charter, who do operate that type, so perhaps they are the real operator.
Oh, and no slots requested yet.
Non-starter or, if it starts, gone within a few weeks I reckon.
