ACMI & Aircraft Leasing

ACMI & Aircraft Leasing — Wet, Damp and Dry

We source and coordinate leased capacity for airlines, operators, governments and tour operators — short-term ACMI cover through to multi-year dry leases — working with appropriately licensed lessors and operators. SkyBridge Jets is a broker and adviser; we do not own or operate aircraft.

Lease Structures

ACMI, Damp and Dry — What Each Actually Means

The structure determines who holds operational control, who carries the regulatory burden and where the risk sits. Choosing it correctly at the outset saves far more than negotiating the rate.

Aircraft lease structures compared

ACMI / Wet Lease

Provided by lessor
Aircraft, crew, maintenance and insurance provided by the lessor
Operational control
Operated on the lessor's AOC, under the lessor's operational control

Fastest route to added capacity: AOG recovery, delayed deliveries, seasonal peaks, route launches and crew shortfalls. The lessee normally pays fuel, navigation, handling, airport and route charges.

Damp Lease

Provided by lessor
Aircraft and maintenance from the lessor, with crew or insurance split between the parties
Operational control
Usually the lessor's AOC, but the split varies by contract

A middle ground — often the lessee supplies cabin crew while the lessor supplies flight crew, or the lessee carries its own insurance. There is no globally uniform legal definition of a damp lease; what it means in practice is set by the contract and the regulator involved.

Dry Lease

Provided by lessor
Aircraft only
Operational control
Operated on the lessee's own AOC, under the lessee's operational control

Fleet growth, replacement aircraft and long-term capacity without outright purchase. Requires the lessee to hold the relevant operational approvals and to complete technical acceptance, registration and insurance work before entry into service.

Sub-charter & AOG Cover

Provided by lessor
Short-notice replacement capacity from a third-party operator
Operational control
Operated by the covering carrier

Protecting a published schedule during unscheduled maintenance, disruption or a delayed return to service, subject to aircraft and crew availability, slots and traffic rights.

Short-Term ACMI

When Airlines Reach for Leased Capacity

Short-term ACMI use cases

AOG recovery & disruption

Covering an unexpectedly grounded aircraft so the published schedule survives, where a compliant aircraft and crew can be positioned in time.

Delayed deliveries

Bridging the gap when an ordered aircraft slips, so the network plan and slot portfolio are not lost.

Seasonal peaks

Summer leisure programmes, winter ski rotations and holiday peaks where owning the extra aircraft year-round makes no commercial sense.

Route launch & proving

Testing a new market with leased capacity before committing to owned or long-leased metal.

Crew shortfalls

Where the aircraft exists but the qualified crew do not, an ACMI arrangement brings both together.

Pilgrimage & seasonal programmes

Hajj, Umrah and comparable seasonal movements requiring widebody capacity for a defined window.

Sports, tour & incentive series

Multi-month charter series for federations, tour operators and event programmes.

Humanitarian & government capacity

Relief, evacuation and government programmes needing passenger, combi or freighter capacity at short notice.

Long Term

Dry Lease & Fleet Planning

Dry lease and long-term fleet planning

Long-term dry leases support fleet growth, aircraft replacement and network expansion without the capital commitment of purchase. We source regional turboprops, narrowbodies, widebodies, freighters and, where the requirement calls for it, business and VIP aircraft — always through third-party owners, lessors and operators rather than from any inventory of our own.

Dry lease induction is a project, not a booking. Depending on the jurisdiction it can require the type on the lessee's AOC and operations specification, technical acceptance of the airframe and records, registration or import and the associated airworthiness work, insurance placement, security deposits or guarantees, and an agreed maintenance and redelivery regime. Planning that sequence properly is usually what determines the realistic in-service date.

Where outright ownership is the better answer — or where a purchase is intended to be placed on lease — our aircraft sales and acquisition advisory covers sourcing, due diligence coordination and transaction support. For a single urgent freight movement rather than sustained capacity, see ad-hoc air cargo charter.

Before You Enquire

The Requirement Checklist

Aircraft leasing requirement checklist

Aircraft type required and acceptable alternatives.

Number of aircraft and whether they are needed simultaneously.

Year of manufacture or age limits, if your regulator or financiers impose them.

Passenger or cargo configuration, including seat count and class layout.

Operating base and the routes or regions to be flown.

Required start date and the term you are contracting for.

Planned monthly utilisation and the MGH you are prepared to underwrite.

Which of crew, maintenance and insurance you need from the lessor.

Your AOC status and jurisdiction, for any dry lease.

Commercial expectation — a budget range, even a rough one, saves a full round of options.

Security position: deposit, bank guarantee or parent-company guarantee available.

Maintenance status and delivery condition requirements, including redelivery expectations.

Process & Due Diligence

From Mandate to In-Service

Aircraft leasing attracts a great deal of unverified circulation. Our process exists to filter it, protect both sides' confidentiality and keep the transaction on a documented footing.

Leasing process and due diligence

01

Mandate & Authority

We confirm who we are acting for and, on the supply side, that the party offering an aircraft actually has authority to offer it. Chains of intermediaries without written authority are declined.

02

Counterparty & KYC

Company standing, ownership, regulatory status and sanctions screening on both sides before any sensitive information is exchanged.

03

Aircraft Identity & Specification

Type, variant, configuration, engine standard and identity confirmed. Serial numbers and registrations are shared only under confidentiality and only when the process genuinely requires it.

04

Records & Maintenance Status

Maintenance status, time and cycles to the next major events, life-limited part status, modification standard and records completeness reviewed by the lessee's technical team or an appointed specialist.

05

LOI / Term Sheet

Commercial heads of terms agreed in writing before either party invests in inspection and legal work.

06

Technical Acceptance & Inspection

Physical inspection and records review, with any rectification and delivery-condition items agreed and documented.

07

Regulatory Coordination

Wet-lease approvals, foreign-operator permits, registration, import and airworthiness work are progressed by the operator, the lessee and their regulatory and legal advisers. SkyBridge Jets coordinates the timetable and keeps the critical path visible.

08

Contract, Induction & Support

Lease documentation is negotiated by the parties and their lawyers. We stay engaged through induction, entry into service and the life of the contract as the commercial point of contact.

SkyBridge Jets provides commercial coordination and introductions. We do not provide legal, tax, airworthiness or accounting advice; those opinions should come from your own qualified advisers, and we will work alongside them.

Commercial Terms

The Vocabulary of a Lease Deal

Commercial lease terms explained

Block-hour rate
The price per block hour flown under an ACMI contract. It normally covers the aircraft, crew, maintenance and insurance, with fuel, navigation, handling and airport charges paid by the lessee.
MGH (minimum guaranteed hours)
A contracted minimum number of block hours per month the lessee pays for regardless of actual utilisation. It is how the lessor underwrites having committed the aircraft and crew to you.
Positioning
Ferry cost of bringing the aircraft to your base at the start of the contract and returning it at the end, plus any repositioning during the term.
Crew rotations
Crew accommodation, per diems, travel and rotation cycles — usually the lessee's cost under ACMI, and a meaningful part of the total.
Maintenance reserves
On dry leases, monthly amounts set aside against future major maintenance events, calculated per flight hour, cycle or calendar month.
Deposits & security
Cash security deposits, bank or parent-company guarantees, or letters of credit — sized against the term, the aircraft value and the counterparty's standing.
Delivery & redelivery conditions
The technical and cosmetic condition in which the aircraft is handed over and must be returned, including hours and cycles remaining to major events. This is frequently the most contested part of a dry lease.
Utilisation & escalation
Minimum and maximum utilisation assumptions, plus how rates move with inflation, insurance markets or contract extensions.

Leasing FAQ

ACMI & Aircraft Leasing Questions

What is the difference between ACMI, damp lease and dry lease?

Under an ACMI or wet lease the lessor provides the aircraft, crew, maintenance and insurance and operates the aircraft on its own AOC, so operational control stays with the lessor. Under a dry lease the lessee takes the aircraft only and operates it on its own AOC, holding operational control and providing crew, maintenance and insurance. A damp lease sits between the two — typically some but not all of crew, maintenance and insurance come from the lessor. There is no globally uniform legal definition of a damp lease; the split is defined by the contract and the regulators involved.

How quickly can an ACMI aircraft be deployed?

It depends on what is genuinely available and where. AOG cover is worked immediately and driven by aircraft and crew positioning, slots, and any wet-lease approvals or traffic rights needed on the routing. A new seasonal contract normally needs a longer runway for regulatory filings, crew training and technical acceptance. We would rather give you a realistic date supported by the operator than a headline turnaround we cannot control.

What are typical lease terms?

Short-term ACMI is commonly arranged from a few weeks of AOG cover up to a full season, with longer ACMI contracts running a year or more. Dry leases are usually multi-year with structured maintenance reserves and defined redelivery conditions. Actual terms are set by the lessor, the aircraft and the market at the time.

What is MGH and how does it affect cost?

MGH is the minimum number of block hours per month you contract to pay for whether or not you fly them. A higher MGH usually buys a lower block-hour rate, because the lessor's utilisation risk falls. Getting the MGH right against your planned schedule matters more to total cost than shaving the headline rate.

What approvals are needed before an aircraft can enter service?

For a wet lease, the lease itself generally needs regulatory approval, along with foreign-operator permits and traffic rights on the routes to be flown. For a dry lease, the lessee needs the aircraft type on its AOC and operations specification, plus registration or import, airworthiness certification, insurance and technical acceptance. These are filed by the operator, the lessee and their advisers; SkyBridge Jets coordinates the sequence rather than filing on their behalf.

What security or guarantees will a lessor expect?

Typically a cash security deposit or an acceptable bank or parent-company guarantee, sometimes supported by letters of credit, together with evidence of insurance and financial standing. The size and form depend on the term, the aircraft, the jurisdiction and the lessee's credit profile. Being clear about your security position early makes the process substantially faster.

Does SkyBridge Jets own or operate aircraft?

No. SkyBridge Jets is a broker, arranger and advisory firm. We do not own aircraft, we do not hold standing inventory and we do not hold an air operator certificate. Every aircraft is owned or operated by an appropriately licensed third party, and every lease is contracted directly between the lessor and the lessee.

Can you handle confidential mandates?

Yes. Requirements and availability are handled on a need-to-know basis, with non-disclosure agreements where appropriate, and sensitive identifiers are withheld until the counterparty is qualified and confidentiality is in place. We do not publish or circulate client requirements.

Can you source freighter capacity as well as passenger aircraft?

Yes. Freighter and combi ACMI is a regular requirement for e-commerce peaks, project cargo lanes and relief programmes. If the need is a single urgent movement rather than sustained capacity, an ad-hoc cargo charter is usually the better structure.
