Aircraft, Crew, Maintenance and Insurance (ACMI)

A form of operational wet lease of an aircraft. An operator may engage into ACMI leasing when they require an aircraft urgently and for a reasonably short time period. During an ACMI lease, the lessor must be an operator themselves and they provide a full service option to the lessee, meaning they provide a ready to fly aircraft with a full flight crew, maintenance support and flight insurance. This is a very expensive way to run an operation, but often necessary if an operator’s own aircraft goes AOG in the middle of a high peak season.
