ACMI Leasing for Charter Operators: How It Works and What to Look For
- May 27
- 4 min read
For charter operators, ACMI leasing is one of the most practical tools for managing demand peaks, covering aircraft downtime, and expanding capacity without the long-term financial commitment of fleet acquisition. This guide explains how ACMI works specifically in the charter operator context — the deal structures, what to look for in a provider, and how to avoid the most common pitfalls.
How ACMI Works for Charter Operators
When a charter operator takes an aircraft on ACMI, they receive a complete, ready-to-fly package: aircraft, crew, maintenance programme, and insurance. The operator then sells and manages flights on the aircraft, typically under the ACMI provider's Air Operator Certificate. The operator pays a lease rate — usually per flight hour or per day — and bears fuel costs, handling fees, landing charges, and overflight permits.
From the client's perspective, the charter appears normal — they book through the operator and fly on the aircraft. The ACMI provider is invisible to the passenger. This is what makes ACMI such a clean capacity solution.
Why Charter Operators Use ACMI
Peak season demand — summer Mediterranean, Christmas ski season, Formula 1 race weekends, and other predictable high-demand windows
AOG coverage — when an owned aircraft becomes unserviceable and a client booking cannot be cancelled or rescheduled
Route trials — testing commercial demand on new routes before committing to fleet investment
Fleet gap — bridging the period between selling one aircraft and acquiring the next
Specific type requirements — clients requesting an aircraft type the operator does not own or cannot source on short notice
What an ACMI Contract Covers
A well-structured ACMI agreement addresses the following elements:
Aircraft specification — make, model, registration, year, configuration, and approved range
Crew — minimum crew qualifications, language requirements, rest rules, and fatigue compliance framework
Maintenance — who holds the maintenance programme, scheduled maintenance windows, and AOG response obligations
Insurance — hull and liability coverage levels, and confirmation that the lessee is named as an additional insured
Minimum guarantees — minimum flight hours per month or a block rate structure protecting the lessor's revenue baseline
Positioning — which party bears the cost of positioning flights (dead legs) to and from the operational base
Exclusivity — whether the lessor can simultaneously operate the aircraft for other clients during the lease period
What to Look for in an ACMI Provider
Not all ACMI providers are equal. Key factors to assess before committing:
EASA (or equivalent) AOC certification — verify independently with the relevant aviation authority
Safety rating — IOSA, ARGUS Platinum, or Wyvern Wingman certification signals operational standards. A rated provider reduces your own risk exposure when presenting the aircraft to clients
Aircraft age and condition — newer, lower-hours aircraft are easier to sell to corporate and HNW clients. Ask for the full maintenance status at the start of the lease
Crew qualifications and recency — minimum 1,500 hours PIC is standard for light/midsize types; more for long-range or heavy jets
AOG response commitment — the contract should specify the maximum acceptable unserviceability window before a replacement aircraft or financial remedy is triggered
Operator references — ask for active references from current lessees, not historical clients
Regulatory Considerations
Charter operators taking on ACMI aircraft should be aware of the following regulatory points:
The aircraft operates under the lessor's AOC — passenger-facing documentation in some jurisdictions will show the lessor as the registered operator
Some aviation authorities require formal wet lease approval before a lessee can begin commercial operations on a leased aircraft — allow time for this in your planning
Crew fatigue rules follow the lessor's regulatory framework, which may differ from the lessee's home country requirements
If the lessee wishes to operate under their own AOC branding, a more formal wet lease arrangement (rather than pure ACMI) may be required
ACMI Pricing Structures
ACMI agreements typically use one of three pricing structures:
Flight hour rate — a fixed rate per block hour flown. Most common for variable-demand operations where utilisation is unpredictable
Daily guarantee — a minimum daily payment regardless of utilisation, plus a variable rate above the threshold. Protects the lessor while giving the lessee operational flexibility
Block rate — a fixed rate for a pre-agreed number of hours per month, with over/under provisions for variance
Indicative ACMI rates for business jets in 2026 range from approximately €2,500 to €8,000+ per flight hour depending on aircraft type, with additional costs for positioning, daily minimums, and specific operational requirements.
Frequently Asked Questions
Can I operate an ACMI aircraft under my own company brand?
The aircraft operates under the lessor's AOC, meaning the registered operator in official documentation is the lessor. The charter is marketed and sold by you. This arrangement is standard in the industry and well understood by aviation authorities. If full operational branding under your own AOC is required, discuss a formal wet lease structure with your broker.
What is a typical ACMI lease duration for a charter operator?
ACMI leases for charter operators typically run from a few weeks to a full season (3–6 months), aligning with identifiable demand peaks. Longer arrangements exist but tend to evolve toward dry lease structures when both parties are committed to a multi-year relationship.
What happens if the ACMI aircraft goes AOG during an active booking?
This is one of the most critical contract points. The ACMI provider is responsible for the aircraft, crew, maintenance, and insurance — including AOG situations. Your contract should specify the maximum acceptable downtime and the remedy triggered if it is exceeded, whether that is a replacement aircraft, a rate reduction, or a financial penalty. Jetvice ensures these protections are included and clearly defined during negotiations.
