How does ACMI leasing compare to owning or dry leasing aircraft?
Picture yourself charting the course for an airline in Europe — Embraer E175/E195s linking regional towns, Boeing 737s and Airbus A320s on the core network, wide-bodies reaching long-haul. Every capacity decision echoes across busy hubs and quiet regional strips. So when demand spikes 20–25% over summer and 1.8 million slots are in play, how should you add aircraft: ACMI, dry lease, or buy?

The three routes explained
ACMI leasing
A rental model that bundles Aircraft, Crew, Maintenance and Insurance. Pricing is per block hour — indicatively €2,500–€10,000 depending on aircraft type and mission — and it is inherently short-to-medium term: around 60% of agreements run under six months (Cirium 2023).
Owning
Buying outright means a capital outlay of roughly €45 million for a regional jet up to €375 million for a long-haul wide-body, full responsibility for every operating cost, and complete control over livery and maintenance scheduling.
Dry leasing
An aircraft-only rental, typically 5–10 years (about 80% of contracts exceed five years). Annual rent runs roughly €1–€7 million, and the operator provides its own crew, maintenance and insurance.
1. Cost comparison
ACMI is pay-as-you-fly. Indicative hourly rates: Embraer E175 ≈ €2,500–€3,500; Embraer E195 ≈ €3,200–€3,800; a three-month E190 programme (≈300 hours) lands near €1 million. A Boeing 737-800 or Airbus A320 runs ≈ €4,000–€6,000 per hour (≈€2.4–€3.6 million for a 600-hour summer); an Airbus A330 or Boeing 777-300ER ≈ €8,000–€10,000 per hour (≈€4.8–€6 million for 600 hours).
Ownership means purchase prices of about €45 million (E175), €110 million (A320) and €375 million (777), plus annual crew, maintenance and insurance (CMI) of ≈€4 million for regionals up to ≈€27 million for wide-bodies. Break-even typically arrives only after 5–10 years at 3,000+ flight hours a year.
Dry leasing sits in between: annual rent of ≈€1–€1.5 million (E175), €2–€2.4 million (737) or €4–€7 million (A330), plus €1–€2 million of CMI — a total annual outlay of roughly €2–€9 million.
2. Speed to take-off
- ACMI: 7–14 days to deployment.
- Owning: 6–12 months to order and take delivery.
- Dry leasing: 1–3 months on average.
In Europe, that speed matters most in slot-retention scenarios (hubs reject around 10% of requests) and for capturing seasonal peaks before they pass.
3. Flexibility in flight
- ACMI: high — with ≈60% of contracts under six months, it is built for route testing. A strong summer (say 85% occupancy) argues to continue; a weak one (65%) lets you simply return the aircraft.
- Owning: low — a ≈€90 million 737 is a decade-plus commitment.
- Dry leasing: moderate — a 5–10 year term is easier to adjust than ownership but is still a long horizon. Regional traffic is growing ≈3.5% a year (Eurocontrol 2024).
4. Control over the cockpit
- ACMI: the lessor manages crew (≈€2–€3 million/year), maintenance (≈€500,000–€1 million per major inspection) and insurance (≈€300,000–€1.8 million/year). You keep the commercial controls.
- Owning: complete control — and complete internal responsibility for all of it.
- Dry leasing: you control crew and maintenance, balancing control against cost. EASA and EU ETS compliance overhead runs roughly €135–€4,800 per flight depending on sector.
5. Risk profile
- ACMI: low — the lessor assumes operational, crew and maintenance liabilities.
- Owning: high — annual depreciation of 10–15%, full maintenance and ETS exposure; a €45 million E175 is subject to substantial value erosion.
- Dry leasing: medium — you cover operating costs without carrying the aircraft's depreciation.
Europe's ground game: practical scenarios
Regional route — Copenhagen–Oslo
A 3-month E175 ACMI lease (≈€900K) supports ≈€1.6M in revenue (88 seats × €150 × 120 flights). Owning the same aircraft would put €44–€46 million at risk if occupancy slipped to 65%.
European core route — London–Madrid
A 6-month 737-800 ACMI lease (≈€2.4M) supports ≈€2.6M in revenue (180 seats × €150 × 90 flights) — against an €88–€93 million long-term commitment to own or dry-lease.
Long-haul test — Frankfurt–Tokyo
A 6-month A330 ACMI lease (≈€4.8M) supports ≈€5.4M in revenue (300 seats × €600 × 90 flights). Ownership or dry-lease economics here only pay off over a 10-year-plus horizon.
Side-by-side summary
| Metric | ACMI | Dry leasing | Ownership |
|---|---|---|---|
| Deployment speed | 7–14 days | 1–3 months | 6–12 months |
| Upfront / outlay | €900K–€4.8M (3–6 months) | €1–€7M annually | €45–€375M |
| Contract length | ≈60% under 6 months | 5–10 years | Indefinite |
| Annual CMI cost | Included | €1–€2M | €4–€27M |
| Flexibility | High | Moderate | Low |
| Risk level | Low | Medium | High |
| Break-even | n/a (usage-based) | 5–10 years | 5–10 years |
Conclusion
ACMI wins on speed and minimal risk for route testing and seasonal demand. Ownership delivers long-term ROI for stable, high-frequency flying measured in decades. Dry leasing is the middle ground — operational control without the capital of ownership. With 1.9 billion passengers projected in Europe by 2030 (ACI Europe), 3.5% annual traffic growth and rising carbon-cost exposure under EU ETS, the flexible option is an increasingly strategic one. Marathon Airlines leans into that with fuel-efficient E-Jets — the E175 (≈88 seats, ≈1,800-mile range) and the E195 (up to ≈118 seats, rivalling narrow-bodies at lower cost).
