Commission Stacking: How Your $18,000 Empty Leg Becomes a $26,000 Retail Ticket

You price an empty leg at $18,000. That is what the aircraft costs to operate on a repositioning flight where you would otherwise earn nothing. A reasonable number, clearly stated.

The traveler who eventually boards that aircraft paid $26,000.

Nobody lied. Nobody broke an obvious rule. The difference moved through a chain of broker margins so quietly that none of the parties in the middle even needed to talk to each other. The traveler is furious. Your tail number is in the booking confirmation they are looking at. And you have no idea what happened between your price and theirs.

This is commission stacking, and it is a structural feature of how informal charter distribution works, not a bug confined to bad actors. Understanding the mechanics is the first step to deciding what to do about it.

Anatomy of a stacked deal

Follow a single empty leg through a typical informal chain.

You operate a midsize jet and have a repositioning flight: three hours at $6,000 per flight hour. You post it at $18,000 to a broker network. The broker is a legitimate business with relationships you want access to. They add a margin of 20 percent, the lower end of the standard brokerage markup range, and show it to their buyer network at $21,600.

None of their buyers bite immediately. A contact at another brokerage firm shows interest and asks for the details. The first broker passes it along. The second firm marks it up a further 15 percent to cover their own overhead, client relationship, and profit. The retail price is now $24,840.

A traveler at the second firm books it. By the time handling fees and a card surcharge are applied, they receive a confirmation for $26,000. The operator, you, receives $18,000. The remaining $8,000 was distributed across two firms the traveler never spoke to and may not know exist.

The math is not unusual. Charter brokerage margins typically run between 10 and 25 percent per layer. A two-layer chain at the conservative end of that range turns an $18,000 operator price into a $25,000 to $28,000 retail ticket without any party behaving dishonestly. Multi-layer deals are common because informal distribution relies on existing broker-to-broker relationships, and those relationships extend through multiple firms.

Why DOT rules do not stop this

The Department of Transportation’s framework for air charter brokers (14 CFR Part 295) requires registered brokers operating in interstate commerce to identify themselves as brokers, not air carriers, and to disclose certain information about the certificated operator conducting the actual flight. What it does not require, in most on-demand charter arrangements, is proactive disclosure of the margin a broker retains above the operator’s base price.

A traveler who asks a broker directly what their markup is may be entitled to an honest answer. A traveler who does not ask receives no automatic disclosure. The retail price is presented as the price, not as an assembled stack of layers.

This is not a loophole being exploited by outliers. It is simply how on-demand charter has operated for decades, in an industry built on relationship-based networks rather than transparent published pricing. The DOT framework was designed for a market of direct broker-to-client relationships. The informal digital distribution chains that now circulate inventory through WhatsApp groups, Telegram channels, and broker networks were not the model it was written for.

The absence of a clear legal violation does not mean the traveler is not disadvantaged, or that the operator is insulated from the consequences when the traveler eventually compares notes with someone who paid less for the same route.

The reputational risk when your tail flies a marked-up ticket

The traveler’s booking confirmation contains your aircraft’s tail number, your operator name, and your crew details. It does not contain the names of the two broker firms that assembled the $26,000 retail price. From the traveler’s perspective, they booked with the source and paid what the source charged.

When a traveler discovers, through a conversation or a search, that the same leg was available for significantly less, their complaint is directed at the name in their paperwork. That name is yours.

This is the reputational structure that commission stacking creates for operators: you set a price that reflected your actual cost and margin, and you absorb the brand damage from a retail price you never saw and never agreed to. The broker firms that captured the difference have no tail number in the traveler’s documents. They face no reputational consequence.

Operators who have experienced this describe it as being held responsible for a customer experience they had no hand in setting. A traveler who overpaid by $8,000 on a private jet booking will not distinguish between a broker markup and operator greed when they describe the experience to their network. The aircraft is yours. The story becomes yours.

How disintermediation protects your margin and your brand

The mechanics of stacking require intermediary layers. Remove those layers and the stacking stops.

On SkyAccess, an empty leg marketplace built for direct operator-to-buyer transactions, operators publish their price and buyers book at that price. There is no broker layer between the operator’s listed price and the traveler’s booking confirmation. The $18,000 repositioning flight is shown to buyers as an $18,000 repositioning flight. The price the traveler pays reflects what the operator set, not what an informal chain assembled from it.

Disintermediation does two things that informal distribution cannot. First, it preserves pricing integrity: the operator’s number is the retail number, so there is no above-market retail price circulating under the operator’s tail number. Second, it keeps the buyer relationship with the operator. The traveler knows who operated the aircraft, books directly on the operator’s paper, and has a contact record that belongs to the operator, not to a broker the traveler will never interact with again.

SkyAccess requires no monthly subscription and no listing fee from operators. The operator network on the platform includes more than 1,500 certified charter operators globally. Travelers browsing empty legs see the discounts that repositioning economics actually produce, which the platform defines as 25 to 75 percent below full charter rates on the same aircraft, without an additional markup layer sitting between the operator’s economics and the traveler’s price.

The transparency dividend

Transparent pricing does something informal distribution structurally cannot: it builds trust across transactions.

A traveler who books a $18,000 empty leg and pays $18,000 has a reference point for the next booking. They know what the aircraft costs to operate, what the discount from full charter looks like, and what a fair price is for a similar route. That traveler is a repeat-booking prospect because they trust the price they received.

A traveler who paid $26,000 for the same leg, and later learns what the operator received, does not come back. They do not refer anyone. They describe the experience as opaque, and that description damages the broader market for legitimate operators who never intended to overcharge anyone.

Commission stacking is not corrected by any individual actor being more ethical. It is a systemic feature of distribution built on informal relationship chains, and it persists as long as inventory circulates through those chains. Operators who remove their inventory from informal networks and publish it directly solve the problem for themselves. They retain pricing control, they receive the margin that the informal chain distributed to intermediaries, and they put their own name on a price their customers can trust.

The $8,000 that disappeared between your listing and the traveler’s confirmation did not go to aircraft maintenance, flight crew training, or the cost of the flight. It went to two firms whose names do not appear on anyone’s booking confirmation. Whether that is a cost worth paying for informal distribution access is a question each operator can now calculate precisely.

Frequently asked questions

Is charter broker commission stacking legal?

In most on-demand charter contexts, yes. DOT’s broker registration framework (14 CFR Part 295) does not mandate proactive disclosure of broker markup. Brokers are required to identify themselves as brokers and disclose the operating carrier, but the margin they retain above the operator’s base price is not subject to automatic disclosure in most on-demand arrangements. Some travelers negotiate disclosure directly; most do not know to ask.

How large do broker markups typically run in private aviation?

Single-layer markups are commonly reported between 10 and 25 percent of the operator’s base price. Multi-layer chains compound these margins. A two-layer chain at 20 percent per layer turns $18,000 into roughly $25,920 before any handling or booking fees are added. The exact markup varies by firm, relationship, and market conditions; these are not disclosed to the traveler in most transactions.

What does FAA Part 135 have to do with charter broker markup?

Part 135 is the air carrier certificate required for the operator conducting the commercial charter flight. Part 135 governs operational safety standards, crew training, aircraft maintenance, and how the flight itself is conducted. It does not govern the commercial chain between the operator and the traveler. An operator can be fully Part 135 compliant while their flight is sold through a stacked broker chain with no limit on markup. Regulatory compliance and pricing transparency are separate frameworks.

How can an operator find out what their flights are being sold for at retail?

In most informal broker arrangements, they cannot without actively searching or having a contact in the buyer network. Operators who distribute through informal channels typically have no visibility into what price their inventory reaches at retail, who bought it, or at what markup. This information gap is a structural feature of indirect distribution.

Does listing on a marketplace like SkyAccess prevent my inventory from being re-listed by brokers elsewhere?

A direct marketplace listing gives the operator a canonical public price that buyers can find and book directly. It does not prevent a broker from independently contacting the operator to inquire about a leg. Operators who want to prevent informal re-listing negotiate direct-booking terms with their distribution partners or publish exclusively through channels where they control the listed price. The marketplace listing itself establishes a price reference that undercuts the commercial case for a large markup: a traveler who can find the direct price has no incentive to pay a stacked one.
