The next time you board a plane, there’s a good chance the airline doesn’t own it. And there’s an even better chance that the company that does own it is based in Ireland.
Ireland is the world capital of aircraft leasing. Companies based in Ireland manage about two-thirds of all the leased passenger jets in the world. Whether you’re flying a low-cost airline in Europe, a carrier in Asia or a domestic flight in the US, your aircraft may well be managed from an office in Dublin or Shannon.
In this guide, we explain what jet leasing is, how a small island became the center of a global industry, which Irish lessors lead the market, and what it all means for travelers and investors.
What is jet leasing?
Jet leasing works much like leasing a car. Instead of buying an aircraft outright, an airline rents it from a leasing company, called a lessor, for a fixed monthly payment over several years. When the lease ends, the airline can return the plane, extend the lease or sometimes buy it.
There are two main types:
- Operating lease. The lessor owns the aircraft and rents it to the airline, usually for eight to twelve years. At the end, the aircraft goes back to the lessor, who can lease it to another airline. This is the most common model in the Irish industry.
- Finance lease. The airline pays off most of the aircraft’s value over the lease and usually ends up owning it. It works more like a loan.
Why do airlines lease planes?
A new passenger jet can cost tens of millions of dollars, and a large widebody can cost much more. Buying planes ties up huge amounts of money. Leasing gives airlines several advantages:
- Lower upfront costs. Airlines pay monthly instead of finding the full purchase price.
- Airlines can add or return aircraft as demand changes, for example during busy seasons or after a downturn.
- Faster access to new aircraft. Big lessors place large orders with Airbus and Boeing years in advance. Airlines can lease new jets from them instead of waiting in the manufacturer’s queue.
- Less risk. The lessor carries the risk of what the aircraft will be worth in the future.
Today, around 41% of the world’s commercial aircraft are leased rather than owned, and that share has grown steadily over the past few decades.
How big is Irish jet leasing?
According to Aircraft Leasing Ireland, the industry body, Irish-based leasing firms and their groups manage:
- 9,504 aircraft
- About 64% of all leased aircraft in the world by number
- More than $315 billion worth of aircraft, around 69% of the value of the world’s leased fleet
- Another 2,383 aircraft on order, more than 95% of them new-technology models that burn less fuel
More than 50 aviation finance companies operate in Ireland, including 14 of the world’s top 15 aircraft lessors. In Dublin alone, more than 3,000 people work in aircraft leasing and finance, and the sector is estimated to contribute about €1 billion a year to the Irish economy.
How did Ireland become the jet leasing capital?
It started in Shannon
The story begins in 1975 at Shannon, in County Clare. Tony Ryan, a former Aer Lingus manager, set up Guinness Peat Aviation (GPA) with backing from Aer Lingus and the Guinness Peat financial group. Ryan, who later co-founded Ryanair, saw that airlines needed flexible ways to get aircraft without buying them.
GPA grew into one of the biggest aircraft lessors in the world. In 1992, its planned stock market listing failed and the company ran into serious trouble. But GPA had trained a generation of aviation finance experts. Many of them went on to start or run leasing companies, and they stayed in Ireland. That pool of talent is still one of the industry’s biggest strengths.
Tax and treaties
Ireland’s tax system has also helped. The country’s corporate tax rate of 12.5% on trading income attracted leasing companies for decades. Since 2024, very large international groups pay a minimum rate of 15% under the OECD’s global tax agreement, known as Pillar Two.
Just as important are Ireland’s double tax treaties with more than 70 countries. These agreements mean that lease payments from airlines in those countries usually aren’t taxed twice. Ireland also allows aircraft to be written off for tax purposes over eight years, which suits the business.
Strong legal protections
Ireland signed up to the Cape Town Convention in 2006, an international agreement that protects lessors if an airline stops paying. It makes it easier to recover aircraft across borders, which lowers risk and makes financing cheaper. The international registry that records these interests, Aviareto, is also based in Dublin.
The biggest Irish jet lessors
Several of the world’s largest aircraft lessors are based in Ireland:
| Lessor | Fleet size (owned and managed) | Base |
| AerCap | About 1,680 aircraft | Dublin |
| SMBC Aviation Capital | About 720 aircraft | Dublin |
| Avolon | About 640 aircraft | Dublin |
AerCap
AerCap is the world’s largest aircraft lessor by a wide margin. It became even bigger in 2021, when it bought GE Capital Aviation Services (GECAS), the leasing arm of General Electric, which itself had deep roots in Shannon. AerCap also leases engines and helicopters.
SMBC Aviation Capital
SMBC Aviation Capital is owned by Japanese financial group Sumitomo Mitsui and is headquartered in Dublin. It celebrated 25 years in 2026 and is the world’s second-largest lessor by fleet size.
Avolon
Avolon was founded in Dublin in 2010 and has grown rapidly into one of the top three lessors worldwide. It’s owned by China’s Bohai Leasing and Japan’s ORIX.
Many other lessors, including some headquartered in Asia and the US, also run large operations in Ireland.
Challenges facing Irish jet leasing in 2026
The industry is doing well, but it faces real pressures:
- Aircraft shortages. Airbus and Boeing are still behind on deliveries, and some new engines need extra maintenance. That means there aren’t enough planes to meet demand. This has pushed up lease rates, which helps lessors in the short term but makes it harder to grow.
- Global tax changes. The 15% minimum tax for large groups reduces Ireland’s tax advantage. Ireland still offers its treaty network, legal framework and experienced workforce, which are harder to copy.
- Competition from other hubs. Singapore, the UAE and the US all want a bigger share of aircraft leasing.
- Geopolitical risk. When Russia invaded Ukraine in 2022, hundreds of leased aircraft were stuck in Russia, and Irish lessors faced large losses. Many have since recovered money through insurance settlements, but it showed how quickly world events can hit the industry.
What does Irish jet leasing mean for travelers?
For most travelers, aircraft leasing is invisible. But it shapes your experience in a few ways:
- More routes and lower fares. Leasing helps new and low-cost airlines launch and grow without buying a whole fleet. Many budget carriers rely heavily on leased aircraft.
- Newer, quieter planes. Lessors focus on new-technology aircraft that are more fuel-efficient and comfortable.
So when you collect points and miles for your next trip, the plane taking you there may well have been financed from an office building in Dublin’s docklands.
Can you invest in aircraft leasing?
Some people are interested in aircraft leasing as an investment. AerCap shares are listed on the New York Stock Exchange, and shares of some other lessors are publicly traded too. Investors can also gain exposure through aviation-focused funds and bonds.
Like any investment, aircraft leasing carries risk. Its fortunes depend on airline demand, interest rates, fuel prices and world events. This article is for information only and isn’t financial advice. Talk to a qualified advisor before investing.

Conclusion
Irish jet leasing is one of the biggest business success stories you’ve probably never heard of. From its start at Shannon in the 1970s, Ireland has grown into the place where about two-thirds of the world’s leased aircraft are managed. Talent, tax treaties, strong legal protections and decades of experience keep it on top, even as global tax changes and competing hubs raise new challenges. Next time you board a flight, take a look at the plane. There’s a good chance its story leads back to Ireland.
