The air in the office at on a Sunday morning has a specific, thin quality, smelling faintly of lemon-scented industrial floor wax and the metallic tang of a cooling HVAC system. It is a sterile environment that stands in sharp contrast to the grit of a runway, yet it is where the most significant decisions in aviation are currently being made.
Priya, a vice president at a mid-market private equity fund, sits within this silence, her sweater pulled tight against the over-efficient air conditioning. On one screen, a confidential information memorandum (CIM) for a mid-sized Fixed-Base Operator (FBO) is splayed open like an autopsy. On the other, a search engine window contains a half-dozen tabs that would be deeply embarrassing to her colleagues: “what is a fuel flowage fee,” “difference between into-plane and retail fuel,” and “how to read an airport lease agreement.”
She feels a mounting sense of fraudulence. Priya has underwritten complex software-as-a-service (SaaS) rollups and managed the debt restructuring of international logistics firms. She is, by every objective measure, a financial heavyweight. Yet, as she stares at the seller’s earnings bridge, she realizes she cannot explain where the money actually comes from.
She assumes this is a personal failure. She believes that if she were smarter, or if she had spent more time at the local municipal airport instead of at a desk in Manhattan, these terms would be intuitive. She is wrong.
For the business of aviation ground support was, for nearly , a vernacular industry passed down through families and former military pilots who spoke a language of handshakes and hangar-floor wisdom. Since the capital now flowing into these assets comes from a population trained in the rigorous, standardized language of the MBA and the spreadsheet, a profound translation gap has emerged.
We call a business an FBO because the term-Fixed-Base Operator-distinguishes it from the itinerant barnstormers of the ; it is a retail fuel station, a parking garage, and a real estate office rolled into one, all operating on a government-owned leasehold.
Understanding the “Into-Plane” Friction
To understand the confusion, one must first define the “Into-Plane” fee, a concept that routinely trips up even the most seasoned analysts. An into-plane fee is the revenue earned by the FBO for the physical act of pumping fuel that the aircraft owner has already purchased from a third party, such as a fuel brand or a fractional provider like NetJets.
A service fee with high margins but low volume. Looks like “easy” processing revenue on the spreadsheet.
A “margin leak.” Every gallon pumped here is a gallon that escaped the higher retail price point.
If a buyer does not understand the ratio of contract fuel to retail fuel, they are not merely miscalculating revenue; they are misreading the entire competitive posture of the airport. The valuation of an FBO is fundamentally a real estate play disguised as a retail business, for the revenue derived from fuel sales is ultimately a function of the exclusive right to occupy a specific patch of asphalt.
This exclusivity is governed by the “Airport Sponsor”-usually a city, county, or regional authority-and is subject to a complex set of federal guidelines known as FAA Grant Assurances. These assurances mandate that the airport be open to the public and that no business be given an “exclusive right” in a way that violates federal law, yet in practice, the physical constraints of a runway often create a natural monopoly.
A first-time buyer often misses the nuance of the “reversionary clause” in a lease. In many airport agreements, every building the FBO owner constructs-the multi-million dollar hangars, the plush passenger lounges-reverts to the ownership of the airport sponsor at the end of the lease term.
This creates a “melting ice cube” effect on the asset’s value. If Priya does not see the date on the master lease, she might be modeling of cash flow on an asset that legally vanishes in .
The feeling of being the slowest person in the room is a predictable result of an asset class changing hands between two populations that do not share a vocabulary. My friend Helen J.-M., a veteran carnival ride inspector, once explained a similar phenomenon in her field.
“When regional fairgrounds are bought by large amusement conglomerates, the new owners look at the maintenance logs and see chaos. They see hand-written notes about ‘rhythm’ and ‘vibration’ rather than torque specifications.”
– Helen J.-M., Carnival Ride Inspector
Helen knows that the ride is safe because she can hear the specific pitch of the gears, a knowledge that is not yet codified in the buyer’s manual. In the same way, an FBO operator knows the health of their business by the tail numbers on the ramp.
Relationships vs. Trend Lines
The operator knows that the Gulfstream G650 that lands every Tuesday morning belongs to a local CEO who always buys a “full top-off” and never asks about the price. A private equity analyst sees that same tail number as a data point in a “transient traffic” column.
The operator sees a relationship; the buyer sees a trend line. When the relationship is not translated into the trend line, the buyer assumes they are missing a formula, when in fact, they are missing a dialect.
The typical range for a fuel flowage fee. Buyers often mistake this fixed sovereign levy for a negotiable variable cost.
This gap is where the most expensive mistakes are made. Because a buyer is embarrassed to ask what a “fuel flowage fee” is-a per-gallon tax paid to the airport for the privilege of moving fuel across the tarmac-they might mistake it for a variable cost that can be negotiated down. It cannot. It is a fixed sovereign levy.
When these small misunderstandings are aggregated across a five-year model, the “upside” of the deal begins to dissolve. The pressure to appear “aviation-literate” prevents many deal teams from conducting the kind of forensic reconstruction required to see the truth.
They accept the seller’s “adjusted EBITDA” at face value because they don’t know how to challenge the “add-backs” related to hangar occupancy or fuel margins. This is where specialized advisory becomes a necessity rather than a luxury.
The Necessity of Translation
For an acquirer to be successful, they must have an independent view of the target’s value that is not filtered through the seller’s optimistic lens. This process involves testing the operating assumptions behind the figures, such as identifying fuel margins that are exposed to a competing FBO on the same field or leasehold terms that cap the ultimate terminal value.
It is often during this phase that a firm like
is brought in to act as the translator. They reconstruct earnings from the ground up, moving past the operator’s dialect to find the hard financial reality underneath. They are the ones who can tell Priya that the “other income” line item she’s been staring at for two hours is actually a one-time insurance settlement, not a recurring revenue stream from de-icing services.
Priya’s desire to “cram harder” before the Monday morning meeting is a noble instinct, but it is misdirected. You cannot cram a culture. You cannot memorize of airport politics in a weekend.
The frustration she feels is not a sign of her inadequacy; it is a signal that the asset she is trying to buy is more human than the software companies she is used to. An FBO is a collection of fuel trucks, heated hangars, and-most importantly-long-standing permissions.
The confusion is not a failure of the reader. It is the natural state of an industry where the “rules of the game” have been unwritten for decades. In the world of aviation M&A, silence is not strength. Every question a buyer is too afraid to ask is a risk they are unknowingly pricing into the deal.
When capital moves into a niche faster than the niche can be explained to it, the delta between the two is filled with “deal friction.” If Priya were to admit to her managing director that she doesn’t understand the “uplift” calculations, she might find that he doesn’t understand them either.
They are both operating in a fog of jargon designed to protect the incumbent operators. The fix is not to work until on a Sunday. The fix is to acknowledge that being an expert in finance does not make one an expert in the “dialect of the ramp.”
The most successful buyers in this space are those who realize that the complexity of FBO economics is a feature, not a bug. It is what creates the “moat” that makes these businesses so attractive in the first place. If anyone could understand an airport lease in , the margins would have been competed away years ago.
The very confusion that keeps Priya awake at night is the reason the asset is worth her time. As the sun begins to rise over the city, Priya finally closes the browser tab that asks what FBO stands for. She realizes she doesn’t need to be an operator to be a great owner; she just needs to know which parts of the spreadsheet are based on physics and which are based on airport politics.
She stops typing the note to “ask someone who knows” and instead writes a single sentence at the top of her Monday morning briefing: “We need to verify the reversionary dates on the Hangar 4 lease before we finalize the offer.”
She has stopped trying to learn the language by herself and has started identifying the gaps where the language fails. That is the moment the confusion stops being a personal burden and starts being a professional tool.
The deal will move forward, but it will do so with its eyes open, recognizing that in the high-stakes world of aviation, the most expensive thing you can own is a question you were too proud to ask.
