What is ACMI Leasing

Also known as wet or damp leasing, ACMI leasing is an agreement between two airlines in which the lessor provides the lessee with an aircraft, crew, maintenance and insurance in return for payment based on the number of block hours operated.

ACMI provides the lessee with additional or replacement capacity, even at short notice.

When to use ACMI Leasing

Airlines face operational disruption on a daily basis. Capacity requirements can change at a moment’s notice. Adapting accordingly is vital. ACMI leasing can provide a flexible solution to immediate and strategic capacity requirements.

ACC Aviation provide expert advice and actively manages our clients’ aviation assets, offering a range of services with the primary goal of maximising value and minimising risk across aviation portfolios.

Urgent Cover

Aircraft and crew can be wet leased in on a short-term basis. A fully-crewed aircraft is provided, minimising service disruption in the event of sudden unforeseen issues (such as an aircraft suffering a technical fault or a lack of available crew).

Planned maintenance and late deliveries

Even when planned, maintenance can take an aircraft out of commission for anywhere between two weeks and three months – potentially leading to service cancellations. Longer-term leasing solutions ensure that scheduled flights continue to operate for the duration of planned maintenance periods. Aircraft manufacturers are currently operating significant outstanding order backlogs, leading to aircraft delivery delays. Airlines can avoid scheduling issues brought about by delayed deliveries with leasing.

Network Continuity

Ensure consistent service across all routes with dependable aircraft coverage.

Seasonal Demand and New Routes

When planning for seasonal peaks or testing new markets and routes, operators need the flexibility to lease additional capacity for as long as required. ACMI provides additional or replacement aircraft quickly, allowing operators to maintain a seamless service without compromising their schedules.

Advantages of ACMI for the Aircraft Lessee

The main advantage of wet leasing is flexibility. Subject to availability, lease operations can begin quickly to meet immediate capacity requirements.

Alternatively, a wet lease can be used over a longer period to provide supplementary seasonal capacity. Wet leasing is also ideal for testing new routes and markets without first making a substantial investment in new aircraft and crew.

An operating or finance lease, also known as a dry lease, typically requires a minimum-term commitment. Purchasing an aircraft represents a significant capital investment that may not be practical for some operators.

Wet leasing is highly flexible and can be used only when required. ACMI allows lessees to supplement fleet capacity without committing to an investment that may not produce a return.

Advantages of ACMI for the Aircraft Lessor

ACMI allows the lessor to achieve greater fleet efficiency with reduced risk. By leasing surplus capacity during quieter operating seasons, lessors can continue generating revenue without the commercial exposure associated with selling tickets.

The income generated through ACMI provides a more consistent revenue stream than variable ticket sales and generally avoids compensation liability under EU Regulation 261/2004.

By taking advantage of counter-seasonal demand in other international markets, fleet capacity can be utilised throughout the year. This spreads operating costs across a greater number of flight hours and reduces hourly operating rates.

Partial ACMI

Damp Leasing

A damp lease is similar to a wet lease, but the lessee has sufficient cabin crew to operate the leased flights. Damp leasing is tailored to an airline’s specific operational requirements to maximise efficiency by removing the costs associated with all or part of the cabin crew and HOTAC.
