Aircraft Delivery Financing in 2026: How Airlines Are Funding the Gap Between Order and Delivery

Key Takeaways

• Aircraft financing starts before delivery through pre-delivery payments.
• PDP financing helps airlines protect liquidity before the aircraft arrives.
• Delivery often shifts funding into bank debt, leasing or other long-term structures.
• Delivery delays can disrupt drawdowns, hedging and fleet-transition plans.
• Lenders assess both airline credit and aircraft quality.
• Strong financing plans connect treasury, delivery timing and fleet strategy.

The expensive part of buying an aircraft does not wait until the keys are handed over. Long before a new aircraft carries its first passenger, the airline may already have paid substantial amounts to the manufacturer, committed financing, arranged hedging and planned the retirement or return of another aircraft.

That matters more when delivery programmes become larger. Boeing's 2026 Commercial Aircraft Finance Market update describes a competitive delivery-financing market in which banks, lessors, capital markets and covered products continue to play different roles across aircraft types and regions. It also points to growing interest in advance-payment financing as airlines manage large orderbooks.

Aircraft financing is therefore better understood as a journey rather than a transaction. Money is required before delivery, again at delivery and then throughout the aircraft's financing life. For airline treasury teams, the challenge is making sure those stages connect without placing unnecessary pressure on liquidity.
 

Why Does Aircraft Delivery Create a Financing Gap for Airlines?

When an airline signs an aircraft purchase agreement, it does not normally wait until delivery to pay the entire purchase price. Payments are made according to contractual milestones, which means capital begins leaving the business while the aircraft is still being produced.

The timing creates the funding gap. The airline is investing in an asset that cannot yet fly, generate passenger revenue or serve as completed aircraft collateral. At the same time, the carrier still needs cash for fuel, salaries, maintenance, existing lease rentals and the rest of its fleet.
 

How Do Pre-Delivery Payments Affect Airline Liquidity?

Pre-delivery payments, or PDPs, are instalments made to the aircraft manufacturer before delivery and credited toward the eventual purchase price.

They are normal parts of aircraft procurement, but they create an unusual cash-flow profile. Airbus's 2025 Annual Review noted that commercial momentum generated healthy inflows of pre-delivery payments, illustrating how material customer advances can be to the manufacturer's working capital. For the airline, of course, those same advances represent cash leaving the business before the aircraft begins earning.

Imagine an airline expecting six aircraft over the next 18 months. It may be profitable and have no difficulty financing the aircraft once delivered, yet still face several PDP dates during the year. Funding all of those payments from cash could leave less liquidity available for maintenance, network growth or an unexpected operating disruption.

 

Why Do Large Aircraft Orderbooks Create Funding Pressure Before Delivery?

One aircraft creates a financing requirement. Fifty aircraft create a treasury programme.

Large orderbooks can produce overlapping PDP schedules, especially when production accelerates and several deliveries fall into the same financial year. Treasury teams therefore need to model not only the eventual aircraft purchase price but also the cash required months or years beforehand.

This is where fleet planning and funding strategy begin to overlap. Decisions around delivery timing, replacement aircraft and lease expiries are part of wider airline fleet management and aircraft acquisition because an aircraft arriving three months earlier or later can change both capacity and cash requirements.

 

What Is PDP Financing and How Does It Work?

PDP financing is short- or medium-term borrowing used to finance some of the payments due to a manufacturer before aircraft delivery.

The concept sounds straightforward, but the collateral position is different from a normal aircraft loan. Before delivery, there is no completed aircraft sitting on the airline's balance sheet for the lender to mortgage. Instead, the financing may be secured through rights under the purchase agreement, PDP-related claims or other agreed security.

 

What Are Pre-Delivery Payments in Aircraft Financing?

PDPs are not an additional financing charge. They form part of the aircraft purchase price.

Suppose, purely as an illustration, an aircraft has an agreed purchase price of £60 million and the airline has already paid £12 million through PDPs by the time delivery approaches. The amount still payable at delivery is reduced accordingly. The financing problem is that the £12 million had to be funded well before the airline had a revenue-producing aircraft.

This timing issue explains why PDP financing exists.

 

How Can Airlines Fund PDPs Before the Aircraft Arrives?

An airline can use its own cash, borrow from banks, obtain specialist PDP facilities or use alternative capital depending on its credit and fleet strategy.

A useful real-world example came in July 2026, when Allegiant disclosed a PDP facility with an available commitment of approximately $231 million to finance part of the pre-delivery payments associated with future Boeing 737-8 aircraft. The Allegiant PDP financing agreement demonstrates the basic principle: capital can be raised specifically for obligations arising before aircraft delivery.

Private lenders can also participate in this part of the market. Private credit in aviation can provide PDP, bridge and aircraft-backed financing where speed, execution certainty or structural flexibility is particularly valuable.

The PDP facility is usually not intended to remain in place for the aircraft's entire operating life. Delivery creates an opportunity to refinance the short-term exposure into a more permanent structure.

 

What Happens Financially When the Aircraft Reaches Delivery?

Delivery changes the financing equation because there is now a completed, identifiable aircraft.

The airline completes technical and contractual acceptance, the remaining purchase price becomes payable and permanent financing can be drawn. Depending on the structure, the aircraft may enter airline ownership, move into a special-purpose financing vehicle or be sold directly to a lessor.

 

How Is the Final Delivery Payment Funded?

There is no single standard answer.

A strong airline might fund part of the aircraft with cash and borrow the rest from a bank. Another may use a sale-and-leaseback, where a lessor purchases the aircraft and leases it back to the airline. A qualifying transaction may use export-credit support, while another borrower may use private credit or structured finance.

The important distinction is between interim and permanent capital. PDP financing helps the airline reach delivery. Delivery financing determines how the aircraft will be funded once it becomes an operating asset.

 

Why Does the Aircraft Delivery Schedule Matter to Treasury Planning?

Consider an airline expecting an aircraft on 1 November.

Its bank financing may be scheduled to draw on that date. The PDP loan may be due to repay at delivery. A currency hedge may mature around the purchase payment, while the outgoing aircraft may be due to return to its lessor shortly afterwards.

If the delivery slips to January, none of those dates automatically disappear.

Treasury may need to extend financing commitments, adjust hedging and keep the PDP facility outstanding for longer. The fleet team may simultaneously need to extend an existing lease or source temporary capacity.

An aircraft delivery schedule is therefore also a funding schedule.

 

Which Aircraft Financing Structures Can Airlines Use at Delivery?

The financing choice normally depends on airline credit, aircraft type, jurisdiction, interest rates, balance-sheet priorities and how much ownership exposure the carrier wants.
 

How Do Bank Debt, Sale-and-Leaseback and ECA Financing Differ?

Bank debt leaves the airline or its financing structure with ownership exposure while creating a scheduled debt obligation. A sale-and-leaseback aircraft transaction transfers the asset to a lessor, meaning the airline exchanges ownership for lease payments and greater capital flexibility.

ECA aircraft financing works differently again. Export credit agencies support eligible exports through mechanisms such as direct lending, guarantees or insurance. The US Export-Import Bank's aircraft export financing framework, for example, describes support for qualifying commercial aircraft and explains how airline credit and aircraft security form part of the financing assessment.

None of these structures is automatically superior. The right answer depends on what the airline wants its balance sheet and fleet to look like after delivery.
 

When Can Alternative Capital or Private Credit Be Useful?

Alternative capital becomes interesting when certainty has value.

An airline might face a firm delivery deadline but find that a conventional financing process cannot move quickly enough. A private lender may be willing to structure a bridge around that timetable, albeit usually at a higher cost than conventional bank debt.

That does not make private credit a replacement for banks. It makes it another tool. An airline might use private capital temporarily and refinance into cheaper long-term debt once the aircraft and financing structure have stabilised.
 

How Do Aircraft Delivery Delays Affect Financing?

A delayed aircraft can produce a counterintuitive result: the airline does not yet have to pay the final purchase price, but its financing position can still become more complicated.

PDP debt may remain outstanding. Lender commitments may need to be extended. The replacement aircraft that was supposed to free an older aircraft for return may no longer be available.

 

What Happens When Funding Is Ready but the Aircraft Is Late?

Suppose a lender has committed funding for a December aircraft delivery, but the manufacturer moves the handover to March.

The airline may not draw the full aircraft loan until March because there is no delivered aircraft to finance. Yet commitment periods, legal documents or hedging arrangements may have been built around December.

This does not mean every delay creates a financial loss. Some cash expenditure is deferred as well. The real issue is whether the financing documents and treasury plan are flexible enough to move with the aircraft.

 

Can Delivery Delays Increase Bridging or Refinancing Requirements?

They can.

Bridge financing is temporary capital used until a longer-term transaction can occur. If a PDP facility was expected to be refinanced on delivery and delivery moves by four months, the bridge may need to remain outstanding for four months longer.

That extension has a cost.

It may also influence the airline's wider capital plan. One aircraft slipping by a month may be manageable. Ten aircraft moving between financial years can change cash requirements, debt balances and liquidity forecasts materially.

 

What Do Lenders Assess Before Financing an Aircraft Delivery?

Aviation finance lenders do not only look at whether an airline can pay interest.

They also look at the asset supporting the loan. If the airline later defaults, the lender wants to understand whether the aircraft can realistically be recovered, sold or placed with another operator.

 

Why Do Airline Credit and Aircraft Collateral Matter?

Airline credit remains the primary source of repayment. A strong route network, healthy liquidity and manageable debt can give lenders confidence that the loan will perform without ever relying on the aircraft.

Collateral provides the second layer of protection.

Aircraft type, maintenance condition, records, configuration and operator demand all affect how useful that protection really is. A popular narrowbody with standard specifications and good maintenance status may be easier to redeploy than a more specialised aircraft with significant maintenance approaching.

For this reason, financing analysis often connects directly with aircraft valuation rather than relying only on the airline's balance sheet.

 

How Does Aircraft Residual Value Influence Financing Risk?

Aircraft residual value is an estimate of what the aircraft may be worth at a future date.

Consider a lender financing an aircraft today with a seven-year loan. The relevant question is not only what the aircraft is worth on closing day. The lender also wants to know whether the outstanding loan balance is likely to remain comfortably below the aircraft's value as both decline over time.

Maintenance complicates that calculation. Two aircraft of the same age can have different recoverable values if one has recently completed major engine work while the other is approaching an expensive shop visit.

This is where technical and financial due diligence begin to merge. Independent aviation consultancy can help connect aircraft condition, records and maintenance exposure with the assumptions being used in a transaction.

 

Why Aircraft Delivery Financing Is Becoming a Treasury and Fleet Strategy Decision

Aircraft financing used to be easy to describe as the money needed to buy an aircraft. That definition is now too narrow for the way large fleet programmes actually work.

Capital can be required years before delivery through PDPs. Interim facilities may bridge those obligations. Permanent debt or leasing takes over when the aircraft arrives. Delivery delays can move those funding dates, while aircraft value and technical condition influence what lenders are prepared to offer.

The strongest approach is therefore to plan the funding path at the same time as the fleet path.

An airline ordering dozens of aircraft should know not only when each aircraft is expected to arrive, but when PDPs fall due, which facilities will fund them, what financing is expected at delivery and what happens if that delivery date moves.

That is the real aircraft delivery financing challenge in 2026. It is less about finding one source of money and more about making sure the right form of capital is available at each stage between order and revenue service.

 

FAQs

What is PDP financing in aviation?

PDP financing funds part of the pre-delivery payments an airline owes to an aircraft manufacturer before the aircraft is delivered.

 

Why do airlines make pre-delivery payments?

PDPs form part of the aircraft purchase price and allow manufacturers to receive scheduled customer payments during the period before delivery.

 

What happens to PDP financing when an aircraft is delivered?

The PDP facility is normally repaid or refinanced into longer-term aircraft financing when delivery occurs.

 

Can an aircraft delivery delay affect financing?

Yes. A delay can extend interim borrowing, move permanent financing drawdowns and require treasury plans or hedges to be adjusted.

 

What do lenders consider when financing aircraft?

Lenders assess airline credit together with aircraft value, liquidity, maintenance condition, records and future residual-value exposure.
