Creeping the thread here, but isn't Rotterdam even more expensive than Schiphol?
Landing fees are a little less at Rotterdam, but not much. But since we're based at Rotterdam, we get a discount.
Both Schiphol and Rotterdam have mandatory handling. But since we're based at Rotterdam, we do our own handling.
I once worked out the total landing cost at Schiphol would be about 70 euros for the landing, and 130 for the handling. Landing at Rotterdam for me is about 20 euros.
