Buying a share
Fractional jet shares for sale come from two sources. The program manager sells interests in its own aircraft, factory-new or already in the fleet, and quotes each by written proposal. Existing owners sell the remaining term of their interest, with the program's consent, to a buyer the program accepts into its agreements. There is no organized exchange, and the programs quote shares by written proposal rather than from a published price list.
Whichever source, what you are buying is an undivided interest in a specific aircraft, a set of multi-year program agreements, and the operational control responsibilities that come with them. We oversee the purchase on the buyer's side: the mission, the proposal comparison, the diligence file, the negotiable points, and the closing with your counsel and tax advisor.
In short
Two sources
The first source is the program itself. NetJets, Flexjet, PlaneSense and the other fractional operators sell interests in their own aircraft against a written proposal that names the aircraft type, the fraction, the term and the fees. Some of those aircraft are factory-new or on order; others are already in the fleet, and an interest in one of those costs less capital because the aircraft is older. What each operator publishes about structure and price is compiled on average cost of fractional jet ownership. None of them publishes a share price list, and a figure circulating elsewhere is an entry point to a proposal, not a price.
The second source is an existing owner. Owners leave programs before the term ends for the ordinary reasons a travel pattern changes, and program agreements commonly allow them to sell the remaining term to a third party, subject to the program manager's consent. The buyer does not simply take the seller's seat. Under 14 CFR 91.1001(b)(3) a fractional owner is someone who holds a minimum interest in a program aircraft and has entered into the applicable program agreements. The program therefore qualifies the buyer and admits them to the agreements, and it commonly holds a right of first refusal, meaning an option to buy the interest itself on the terms the buyer offered.
What neither source offers is a marketplace. There is no organized exchange where interests are listed and cleared, and a resale runs through the program manager's consent. A buyer looking for a resale interest in a particular aircraft category may be waiting for a seller rather than choosing among them. That shapes the search: the proposal from the program is the dependable channel, and a resale interest is an opportunity to be tested when it appears, not a strategy to be relied on.
What you receive
A general description of the three ways an interest is acquired in a fractional program, stated as our own view. Terms differ by program, by aircraft and by agreement; the written proposal and the executed documents control.
| Factor | New interest from the program | In-fleet interest from the program | Resale interest from an owner |
|---|---|---|---|
| Who sells it | The program manager, against a factory-new aircraft or a delivery position | The program manager, against an aircraft already in its fleet | An existing owner, selling the remaining term |
| Term you receive | A full term, commonly written for several years, as the proposal states | A full or shortened term, as the proposal states | What remains of the seller's term, unless the program writes a new one |
| Aircraft age at your exit | The youngest of the three, so the residual value method starts from the highest base | Older at entry, so lower capital and a lower base for the exit calculation | The same aircraft the seller held, at whatever age the remaining term ends |
| Hours | The allocation attached to the fraction, from the first contract year | The allocation attached to the fraction | Set by the agreement; unused hours are commonly forfeited rather than passed on |
| Who sets the price | The program, by written proposal | The program, by written proposal | The seller, subject to any right of first refusal the program holds |
| Consent | None beyond the program's own qualification of you as an owner | None beyond the program's own qualification | The program manager's consent, your qualification, and your entry into the program agreements |
| Where negotiation happens | In the proposal, before signature: term, hours, escalation, exit and transfer provisions | In the proposal, with the aircraft's age and maintenance status now part of the price | With the seller on price, and with the program on the terms you inherit |
The asset
A fractional share is not a block of flight hours. It is an undivided ownership interest in one specific aircraft, conveyed by a bill of sale and recorded with the FAA, which under 49 U.S.C. 44107(a) keeps the system for recording conveyances that affect an interest in a civil aircraft. The aircraft is registered in the legal name of its owners under 14 CFR 47.5(b), and the FAA's registration application carries a co-owner category for exactly this situation, signed by every co-owner. The eligibility rules in the next section therefore apply to you, or to your entity.
Around that interest sit the program agreements. Under 14 CFR 91.1001(b)(5) a fractional ownership program is a system of multi-year agreements covering the ownership, the management services and the dry-lease aircraft exchange. The exchange is the arrangement that makes the program aircraft available to each owner without crew when their own is elsewhere. Those agreements are what turn an interest in one airframe into access to a fleet, and they are also where the fees, the escalation, the peak-day rules and the exit are written.
The third thing you acquire is a responsibility. On signing the management contract, 14 CFR 91.1013 requires the program manager to brief you on your operational control responsibilities. It also requires you to sign an acknowledgment covering compliance with the regulations, enforcement for noncompliance, and liability risk in a flight-related occurrence. That acknowledgment is not a formality of the closing. It is the regulatory reason a fractional owner is an owner and not a passenger, and it is why how fractional jet ownership works is worth reading before the proposal, not after.
Eligibility
Because the interest is registered, the FAA's registration rules apply to the buyer. Under 14 CFR 47.3 an aircraft may be registered only if its owner is a citizen of the United States or an individual foreign citizen lawfully admitted for permanent residence. A non-citizen corporation organized and doing business under United States or state law also qualifies, provided the aircraft is based and primarily used in the United States. For an entity, 49 U.S.C. 40102(a)(15) defines a citizen as a corporation or association whose president and at least two thirds of its directors and managing officers are U.S. citizens, which is under the actual control of U.S. citizens, and in which at least 75 percent of the voting interest is owned or controlled by U.S. citizens.
On a co-owned aircraft each co-owner signs the registration application and certifies eligibility, so the test is applied to you, not to the program. A buyer who does not meet it is not shut out of fractional flying. Under 14 CFR 91.1001(b)(4) a fractional ownership interest includes a multi-year leasehold interest, which is one reason the programs offer leases alongside shares, and owner trusts exist for the same purpose. Which structure fits your situation, and what it does to the tax treatment, is a determination for your counsel and tax advisor before a proposal is requested.
The entity question matters for United States buyers as well. The interest can be held personally, through an operating company or through a special-purpose entity. The choice affects the registration, the sales and use tax exposure in the state where the aircraft is based, the depreciation analysis and the liability picture. It is settled before the purchase agreement is drafted, because changing it afterwards is a transfer, with the consent, fee and tax consequences described in transferring a fractional jet share.
Reading the offer
The share price is the number every proposal leads with, and in our view it is the one that matters least to the five-year total. The four cost layers of a share are the capital, the monthly management fee, the occupied hourly rate with its fuel surcharge, peak premiums and tax, and the capital that does not come back at exit. The last of those is set by the residual value method and the deductions in the agreement, and those provisions are negotiable only before signature. Our checklist of what to normalize before two proposals can be compared is on the acquisition guidance page.
A resale interest adds a second set of checks. How much of the term remains, and whether the program will write a new term or hold you to the seller's. Whether the seller's unused hours pass to you, which many agreements do not allow. Whether enhancements the seller negotiated survive the transfer. Who pays the transfer fee, and whether the program's right of first refusal has been waived in writing. Whether the seller is in good standing, since arrears usually block consent. And the aircraft itself: its age, its maintenance status, and the registry record your counsel searches for recorded conveyances and liens.
Federal tax on the flying follows the structure, not the source. Program flights under Part 91 Subpart K, the rules fractional programs operate under, carry the fuel surtax of 26 U.S.C. 4043 rather than the percentage tax that applies to charter and card flights. That does not change between a new and a resale interest, but the state sales and use tax on the purchase itself can, and it belongs with your tax advisor before the price is agreed.
Worked comparison
Illustrative only, and not any operator's pricing, fee or valuation. Round figures chosen to show the comparison: the same aircraft category, the same fraction, the same monthly fee and hourly rate, bought new for a full term or bought from an owner with half the term left. Fees, hours and tax are identical and are left out; only the capital is compared.
| Factor | New 1/16 interest, 60-month term | Resale 1/16 interest, 30 months remaining |
|---|---|---|
| Capital paid | $1,200,000 | $500,000 |
| Months of access bought | 60 | 30 |
| Proceeds at exit, illustrative | $700,000 under the residual value method | $300,000 under the same method |
| Capital consumed | $500,000 | $200,000 |
| Capital consumed per month of access | $8,333 | $6,667 |
| What the number does not show | The aircraft is five years older at exit; the fee escalation runs for five years | The exit arrives in half the time, and the next decision with it |
Reading the arithmetic
Illustrative only, and not any operator's pricing: in the worked table the resale interest consumes $6,667 of capital per month of access and the new interest $8,333. The resale buyer pays a fifth less for each month of the same access. That is real, and it is where the case for a resale interest usually rests. The capital is smaller, the commitment is shorter, and the exit arrives while the buyer still remembers why the share was bought.
The same table shows what the case leaves out. The resale buyer's exit comes in thirty months, on an aircraft that is thirty months older than the new buyer's will be at the same point, and the residual value method will be applied to that older airframe. The next decision, whether to buy again, renew or leave, arrives twice as soon, with its own transaction costs. And the hours: if the seller's unused hours are forfeited on transfer, the buyer's first contract year may deliver fewer hours than the fraction implies. None of that makes the resale interest the wrong purchase. It makes it a different one, and the comparison has to be run on months of access and hours delivered, not on the two share prices.
Where the flying is not yet certain enough to commit capital at all, the same arithmetic points elsewhere. A jet card below about 50 hours a year, and whether fractional jet ownership is worth it at the hours you actually fly, are the two questions to settle before a share of any kind is priced.
We compare the share on offer with the alternatives on the same trips, read the exit and transfer provisions before signature, and run the diligence and closing checklist with your counsel and tax advisor.
Oversight
A purchase is a sequence, and most of what it costs over five years is decided in the order the steps are taken. The engagement runs in six, and each leaves the buyer with something they keep whether or not the purchase proceeds.
Scope
We define the mission, compare the interests on offer on one set of assumptions, assemble the diligence file, identify the negotiable points and keep the closing sequence alongside your counsel and tax advisor.
Our work is advisory and does not replace legal, tax, investment, appraisal, aircraft-operating or safety-management advice. Where those questions arise, and on a commitment of this size they usually do, they belong with the professionals responsible for them. We are happy to work alongside yours.
Before signature
Everything on this list is answerable from the proposal, the draft agreements and the aircraft record. Where a proposal does not state an item, record it as unknown rather than as favorable, and ask for it in writing.
Tax treatment is a question for your own tax advisor, and the meaning of any provision is a question for counsel. The written proposal and the executed agreements control.

Fractional Aviation Advisors is an independent, client-side advisory firm. We are not affiliated with the operator, and we take no operator commissions or referral fees. We are not a direct air carrier, air charter broker, broker-dealer, lender, law firm or tax advisory firm, and we do not operate aircraft. Who holds operational control depends on the regulatory framework of the flight. On Part 135 charter and most jet card flights, the certificated air carrier operating the flight holds it (14 CFR 135.77). In a fractional program under Part 91 Subpart K, the owner who directed a program flight is in operational control, jointly and individually responsible with the program manager (14 CFR 91.1009 and 91.1011). We do not guarantee savings, availability, pricing, negotiation outcomes, or that any program will suit your requirements.
