Leasing is a core part of how aviation businesses manage their fleets. It enables operators to access aircraft without the full financial burden of ownership. It is particularly useful to scale up, enter new markets or manage temporary spikes in demand.
Among the different types of aircraft lease, the most widely used are the dry lease and wet lease models. Each comes with its own set of responsibilities, costs and regulatory requirements. The choice of wet vs dry lease is not only about budget—it also affects operations, timelines and compliance. In this article, we explore how these two leasing models differ and where each one fits best.
What is a Wet Lease?
A wet lease refers to an arrangement in which the lessor provides the aircraft along with crew, maintenance and insurance. This type of aircraft lease is often called ACMI, short for Aircraft, Crew, Maintenance and Insurance and is ideal for those who require a ready-to-operate aircraft.
Aircraft Wet Lease Explained
In a dry vs wet lease comparison, the wet lease allows the lessor to retain operational control. The lessee pays for the hours flown but does not have to manage staffing, maintenance or regulatory compliance.
When to Use a Wet Lease
Wet leases work well in situations where speed, flexibility or temporary capacity is essential. They allow operators to fill short-term gaps without long-term investment or infrastructure.
- Short-term or seasonal capacity needs
Airlines often face sudden increases in demand during holidays or peak travel seasons. In such wet lease vs dry lease aircraft situations, wet leasing provides the fastest solution. - New route launches
When testing unproven routes, airlines prefer to avoid upfront investments. Here, a wet lease vs dry lease aircraft decision typically favours wet leasing as it reduces initial risks. - Covering for grounded fleet (AOG)
Aircraft on Ground incidents can disrupt schedules and revenue. Wet leasing provides immediate access to operational aircraft while maintenance is carried out on the grounded fleet. - Governments and humanitarian missions
In times of crisis or natural disasters, governments and aid agencies need fully operational aircraft quickly. Wet leases offer a dependable solution with all support elements included.
What is a Dry Lease?
A dry lease is a more hands-off arrangement for the lessor. It is where only the aircraft is provided. The lessee takes full responsibility for staffing, maintenance, insurance and regulatory compliance.
Aircraft Dry Lease Explained
When comparing wet lease vs dry lease, the dry lease is typically used by certified operators who already possess the required infrastructure and licences. The aircraft is handed over without crew, and the lessee operates it under their own AOC (Air Operator Certificate).
When to Use a Dry Lease
Dry lease suits operators with established infrastructure and long-term plans. They offer lower costs over time and allow for full control of operations.
- Scheduled carriers looking to expand
Airlines often use dry leases to grow their fleet without taking on the financial risk of buying aircraft. In a wet lease vs dry lease scenario, the dry lease supports long-term expansion strategies. - Operators with required licenses and infrastructure
Only operators with a valid AOC can legally manage a dry-leased aircraft. - Companies seeking operational control and cost efficiency
Dry leases are more economical over time since operators manage the entire process. A wet lease vs dry lease aircraft evaluation often shows dry leasing is the more efficient choice for established airlines.
Key Differences of the Aircraft Wet Lease vs Dry Lease
Understanding the functional and regulatory differences between these leasing models can help you select the right fit for your organisation. A wet lease vs dry lease aircraft comparison highlights how responsibilities are divided.
| Aspect | Wet Lease | Dry Lease |
|---|---|---|
| Crew Provided | Yes | No |
| Maintenance & Insurance | Included | Lessee’s Responsibility |
| AOC Needed | No | Yes |
| Typical Duration | Short-Term | Long-Term |
| Control & Liability | Lessor | Lessee |
| Use Case | Emergency or short-term requirement | Expansion or long-term operational planning |
Cost Implications: Dry Lease vs Wet Lease Aircraft
A wet lease vs dry lease assessment shows that wet leases generally cost more because they include the crew, maintenance and insurance. However, this bundled approach offers stability in pricing and reduces operational burden. It is useful for short-term or urgent needs.
Dry leases are more affordable over time, but demand strong internal resources. Since the lessee handles all aspects of operation, it is more cost-effective when the right systems and teams are already in place.
Safety and Compliance: Aircraft Dry Lease vs Wet Lease
Safety and compliance depend on who controls the aircraft’s operations and whether they meet regulatory standards. In a wet lease vs dry lease model, the lessor ensures all certifications and procedures in a wet lease, while a dry lease places the burden entirely on the lessee.
Operators choosing between wet lease vs dry lease must evaluate whether they have the infrastructure to meet all training, maintenance and documentation requirements internally.
Choose the Right Lease for Your Needs
Selecting the right lease depends on how your operations are set up. A wet lease is ideal when you need an aircraft quickly and want minimal responsibility. A dry lease works better for operators who already have crew, certifications and ground support in place.
There are also hybrid models like Damp Leasing. It offers partial crew support while leaving other responsibilities with the lessee. Each lease type serves a different purpose and suits a different stage of business growth. At Air Charter International, we help you assess what fits best. With the right guidance, a wet lease vs dry lease decision can support not just operations, but also long-term strategy and cost planning.
Typically a damp lease means the lessee will provide its own trained cabin flight attendants to provide a consistent onboard experience for passengers as per the airlines own SOP’s. Whilst the cock-pit crew is still provided by the lessor and they maintain operational control of the aircraft.
Common FAQs About Wet and Dry Leasing
1. What is the main difference between wet and dry lease?
The wet lease vs dry lease difference lies in the fact that the wet lease includes the aircraft along with operational support such as crew, maintenance and insurance, while a dry lease includes only the aircraft.
2. Can I operate a dry-leased aircraft without an AOC?
No. A dry lease requires the lessee to have a valid Air Operator Certificate in order to manage and fly the aircraft legally.
3. Which is more cost-effective: wet lease or dry lease?
A wet lease vs dry lease aircraft evaluation shows that dry leases are generally more cost-effective in the long term. Wet leases are better suited for short-term or emergency operations where infrastructure is limited.
4. Do I need to register the aircraft under my name in a dry lease?
In most cases, yes. The lessee typically registers dry-leased aircraft. This is done per the laws of the operating jurisdiction.
5. Is maintenance included in a dry lease?
No. Maintenance, crew and all other operational responsibilities fall under the lessee’s scope in a dry lease agreement.
