What are Wet And Dry Leases? A wet lease is the lease of an aircraft including its crew. So, in reality, it is an ACMI lease . A dry lease is the lease of the aircraft only . In this case, we provide the aircraft and the lessee has to provide everything else. However, we need to make sure that the client is fully capable of operation the aircraft to our stringent standards, so we tend not to do this very often . Dry leased are normally charged at a fixed monthly rate, plus hourly charges for maintenance reserves. They are normally for periods of at least six months . Wet and dry leases are only available to other airlines holding valid Air Operator’s Certificates and the required route a civil aviation have to honor authorities-all other companies who have to charter in aircraft .
