What is Wet Lease (Aviation)?

A wet lease in aviation is a contractual agreement between two airlines where one airline (the lessor) provides an aircraft, complete crew, maintenance, and insurance (ACMI) to another airline (the lessee). This comprehensive arrangement allows the lessee to operate flights under its own flight code, often utilizing the lessor’s aircraft and operational expertise.

This type of lease is typically short to medium-term. It is frequently employed to manage temporary increases in passenger demand, cover periods of maintenance on the lessee’s own fleet, or mitigate the impact of unforeseen aircraft groundings. A wet lease provides an immediate operational solution without the long-term capital commitment of purchasing or dry leasing an aircraft.

The lessor maintains operational control of the aircraft and crew, adhering to its own regulatory certifications and Operations Manual. This includes compliance with safety standards and crew training. The lessee pays an hourly rate for the aircraft’s operation, covering all ACMI costs, while handling fuel, landing fees, passenger services, and other variable expenses.
