Typical charter day:
get up at 2:00, fly to an island about 3 hrs away, return to a different airport, grab a taxi for a 300km ride to the next, sleep for a couple of hours in a hotelbed, get up at 2:00, fly to another island, and, when your happy, land at home.
Typical winters month:
heeps of standby, some off-days and one or two flights to a sunny island. Next mont the same.
Better than street wyping, anyway
