A dry lease involves a private jet leasing arrangement where the aircraft owner provides only the aircraft, without pilots or cabin crew. The lessee pays a fixed hourly rate, directly purchases the fuel, and contracts and pays for the flight crew separately. In contrast, a wet lease includes the aircraft along with at least one crew member, and the owner or operator covers fuel, maintenance, and insurance.
Another important distinction is operational control. In a dry lease, the lessee has complete operational control over the flights. Conversely, in a wet lease, since the owner or operator supplies the crew, fuel, maintenance, and insurance, they retain operational control.
