Choosing the wrong operational structure for a private or commercial aircraft is one of the most expensive mistakes an owner can make. A dry lease transfers the aircraft to a lessee without crew, placing full operational control and regulatory responsibility with the lessee [flyingfinance.com]. A wet lease provides the aircraft along with crew, maintenance, and insurance [aersale.com]. ACMI (Aircraft, Crew, Maintenance, and Insurance) is a structured variant of wet leasing, commonly used for capacity supplementation [sassofia.com]. Each model carries a fundamentally different risk profile, cost base, and regulatory burden. Getting this decision right requires more than reading a comparison chart; it requires advisory experience grounded in the Asia-Pacific regulatory and operational environment.
TL;DR
- A dry lease gives the lessee an aircraft only, with no crew or services, making the lessee fully responsible for operations [avico.com].
- A wet lease bundles aircraft, crew, maintenance, and insurance under the lessor’s AOC, shifting operational responsibility back to the lessor [aersale.com].
- ACMI is a specific wet lease variant where the lessee provides only ground handling and pays for fuel, positioning it as a capacity tool rather than an ownership strategy [sassofia.com].
- Each structure has distinct tax, regulatory, and liability implications that vary significantly across APAC jurisdictions.
- L’VOYAGE’s Private Aviation Advisory team (PATL) helps owners evaluate these structures against their actual usage profile, not just their stated preferences.
About the Author: L’VOYAGE is a government-licensed travel agency and private aviation consultancy headquartered in Hong Kong, with offices across Hong Kong, Shenzhen, Kuala Lumpur, and the APAC region. Through its advisory arm, Private Aviation Technology Ltd. (PATL), the team has guided aircraft owners, flight departments, and aviation startups across the region on acquisition, management, and operational structure decisions since 2014.
What Exactly Is a Dry Lease and Who Should Use It?
A dry lease is a rental arrangement in which the aircraft is delivered to the lessee with no crew, no maintenance contract, and no insurance provided by the lessor [avico.com]. The lessee must hold or obtain its own Air Operator Certificate (AOC), hire and manage its own flight crew, and carry its own hull and liability insurance [flyingfinance.com].
This structure suits:
- Established airlines or operators that already hold an AOC and need additional fleet capacity without taking on ownership costs.
- Corporate flight departments that are large enough to manage their own crew and maintenance infrastructure.
- Aircraft investors looking to place an asset with a qualified operator on a long-term basis without retaining operational involvement.
The key trade-off is control versus complexity. The lessee gains complete scheduling autonomy and branding flexibility but absorbs the full regulatory and liability burden [aircharterservice.com]. In APAC, where AOC requirements differ meaningfully between Hong Kong, Malaysia, mainland China, and other jurisdictions, a dry lease arrangement without experienced local advisory support can expose a lessee to costly compliance gaps.
What Is a Wet Lease and When Does It Make More Sense?
A wet lease bundles the aircraft with crew, maintenance, and insurance under the lessor’s own AOC [aersale.com]. The lessee is essentially purchasing capacity, not operational responsibility. The lessor retains control of the aircraft and its airworthiness, and the lessee receives a fully operable asset ready for deployment.
Building on the dry lease distinction above, the harder question is not which structure sounds simpler, but which structure matches the lessee’s actual regulatory standing and operational depth.
Wet leasing is appropriate when:
- The lessee does not hold its own AOC and cannot realistically obtain one within the required timeframe.
- The need is seasonal or temporary, such as covering peak demand periods or a specific route launch.
- The lessee wants to limit liability exposure, keeping maintenance and crew accountability with the lessor.
One underappreciated consideration in APAC is that wet leasing across international borders can trigger bilateral air services agreement (ASA) restrictions. An aircraft wet-leased from a Hong Kong-based operator to a lessee operating routes into and out of Southeast Asia may face cabotage limitations or require specific government approvals depending on the route and flag state. This is precisely the type of jurisdictional nuance that a generalist advisor is unlikely to flag early enough.
How Does ACMI Differ From a Standard Wet Lease?
ACMI stands for Aircraft, Crew, Maintenance, and Insurance. It is technically a subset of wet leasing, but it has a more precise commercial definition [scribd.com]. Under an ACMI arrangement, the lessor provides those four elements. The lessee takes responsibility for fuel, ground handling, airport fees, navigation charges, and other trip-specific costs [sassofia.com].
| Element | Dry Lease | Wet Lease | ACMI |
|---|---|---|---|
| Aircraft | Lessee operates | Lessor provides | Lessor provides |
| Crew | Lessee provides | Lessor provides | Lessor provides |
| Maintenance | Lessee manages | Lessor manages | Lessor manages |
| Insurance | Lessee arranges | Lessor arranges | Lessor arranges |
| Fuel & Ground | Lessee | Often bundled | Lessee |
| AOC Used | Lessee’s | Lessor’s | Lessee’s (in most cases) |
| Best For | Fleet expansion, control | Seasonal capacity | Short-term supplemental lift |
ACMI leases are typically short-term and are commonly used by airlines facing a temporary aircraft shortage, schedule disruption, or rapid route expansion [sassofia.com]. For private aircraft owners in the APAC region, ACMI is less commonly a starting structure and more often a secondary arrangement used once a management or charter operation is already in place.
What Are the Regulatory and Tax Implications Specific to APAC?
Stepping back from the structural detail, a separate concern is that the APAC region is not a single regulatory environment. It is a patchwork of aviation authorities, tax regimes, and bilateral agreements. The implications of each lease type shift considerably depending on where the aircraft is registered and where it operates.
Key regional considerations include:
- Aircraft registration jurisdiction: Hong Kong-registered aircraft operate under HKCAD oversight. Different rules apply to Malaysian, Cayman Islands, or Isle of Man-registered aircraft, all of which appear commonly in APAC private aviation portfolios.
- Import duties and GST/VAT on aircraft: Several ASEAN jurisdictions impose import duties or consumption taxes on aircraft brought in under dry lease arrangements, which can materially affect the net cost comparison.
- Crew licensing and recognition: Pilot licenses must be validated or converted in each operating jurisdiction; the responsibilities differ between dry and wet lease structures.
- Withholding tax on lease payments: Cross-border lease payments can attract withholding tax in some APAC jurisdictions; the applicable rate depends on the tax treaty position between the lessor’s and lessee’s home countries.
None of these factors appear in a generic lease type comparison. They surface only through hands-on experience in the region, which is why advisory engagement before signing a lease is not optional for owners serious about cost control.
Frequently Asked Questions
Can a private aircraft owner use a wet lease structure to generate revenue from their aircraft?
Yes. An owner can wet-lease their aircraft to an operator who then uses it under that operator’s AOC. The owner receives lease income without managing operations. However, the owner must ensure the lessee-operator maintains appropriate coverage and the arrangement complies with the registration state’s rules.
What is the minimum practical duration for an ACMI arrangement?
ACMI leases can be as short as a few days for specific event or route coverage [sassofia.com]. There is no fixed minimum, but the administrative and contractual setup cost makes very short engagements less practical without an established operator relationship.
Does a dry lease require the lessee to obtain a new AOC?
Yes. If the lessee does not already hold a valid AOC in the relevant jurisdiction, it must obtain one before operating an aircraft under a dry lease. This process can take months and involves significant regulatory preparation [avico.com].
Is ACMI or wet leasing suitable for a startup airline in Southeast Asia?
Wet lease and ACMI arrangements are commonly used by new airlines precisely because they allow the lessee to operate without owning aircraft or holding extensive maintenance approvals. Regulatory acceptance varies by country, so local advisory input is essential before committing.
How does the choice of lease structure affect charter pricing if the owner plans to place the aircraft on a charter program?
Lease structure directly affects which AOC the aircraft operates under and therefore which operator’s safety and pricing profile applies. This has downstream effects on what the aircraft can be offered for on the charter market and whether empty-leg repositioning opportunities can be captured effectively.
What role does an advisory firm play beyond recommending a lease type?
A qualified advisor reviews the owner’s full picture: usage profile, budget, tax residency, registration jurisdiction, preferred operator relationships, and exit options. The lease type recommendation is the output of that analysis, not the starting point.
Does L’VOYAGE handle the aircraft management after advising on structure?
Yes. Through its Further Fleet Initiatives arm and PATL advisory division, L’VOYAGE offers hybrid aircraft management solutions and can serve as a long-term operational partner beyond the initial advisory engagement.
