Two fractional proposals can advertise nearly identical hourly numbers and still generate very different invoices. The gap usually hides inside one figure buyers misread more than any other: the occupied hourly rate. This guide breaks that number down line by line, shows what fractional programs typically fold into it, flags what commonly lands on your bill as an extra, and walks through a sample invoice with the math spelled out.
In fractional jet ownership, the occupied hourly rate (OHR) is the per-flight-hour charge billed for time the aircraft is flown with passengers onboard, and it typically covers direct operating costs such as fuel, routine maintenance, and engine/parts reserves. Items like de-icing, certain airport and international fees, fuel surcharges, and taxes may be billed separately depending on the contract.
"The occupied hourly rate is one of the most misunderstood numbers in private aviation because it's often mistaken for the total cost of flying. In reality, it's only one component of a much larger pricing structure that also includes fixed ownership costs, contract terms, and trip-specific charges that can materially change the final invoice."

Quick answer
Typically included: direct operating costs that rise with flying, meaning fuel (or a fuel portion), routine maintenance, engine and parts reserves, and consumables.
Usually extra: de-icing, international handling, peak-day surcharges, repositioning outside a service area, and taxes such as Federal Excise Tax.
Contract-dependent: taxi-time adders, minimum billable time per leg, and whether fuel sits inside the rate or on its own line.
The occupied hourly rate is the per-hour flight charge in a fractional program, billed for the time you are flying with passengers onboard, intended to cover direct operating costs that scale with flight activity. An occupied hour is a billable flight hour with passengers aboard. That differs from block hours, which are the pre-allocated hours tied to your share size (roughly 50, 100, or 200 hours for a 1/16 share, 1/8 share, or 1/4 share).
Fractional pricing lives in three buckets. Share acquisition is your upfront capital. The monthly management fees cover fixed overhead. The occupied hourly rate is variable and applies only when you fly. Put simply, the occupied hourly rate is the "when-you-fly" fee; the monthly management fee is the "even-if-you-don't-fly" fee.
Cost bucket | When you pay | What it covers |
|---|---|---|
Share acquisition | Upfront, once | Your percentage interest in the aircraft or category |
Monthly management fee | Fixed, every month | Crew, training, insurance, hangar, administration |
Occupied hourly rate | Variable, only when you fly | Fuel, maintenance, engine and parts reserves, consumables |
One warning before you compare two rate sheets: "OHR" and "all-in" are not universal terms. NetJets, Flexjet, and PlaneSense each define billable time a little differently, and some providers add taxi time to occupied hours. Flexjet, for example, references charging its occupied hourly rate for in-flight time plus an additional 2/10 of an hour for taxi time on each leg.
If you see OHR on a proposal, these are the items it is usually trying to bundle. Each one belongs there for the same reason: the cost climbs when the aircraft flies.
Fuel, or a portion of fuel. Some providers fold fuel into the headline rate. Others publish a base rate and then apply a separate variable fuel line that resets periodically. Confirm which model applies before you compare two numbers.
Routine maintenance and consumables. Scheduled inspections, fluids, tires, and brakes wear down with hours and flight cycles. Cabin cleaning and turn costs often ride along too, depending on the program.
Engine and parts reserves. Engine reserves are funds allocated per flight hour to cover future engine maintenance and overhauls, smoothing large maintenance costs into predictable hourly charges. Parts reserves work the same way for high-cost components. Both scale with flight time and cycles, which is why they sit inside the rate rather than hitting you as one giant bill after an overhaul.
Trip-related standard services. Certain programs include routine catering, cleaning, or standard landing fees inside the occupied hourly fee. NetJets publicly describes its occupied hourly fee as covering direct operating costs along with items such as landing fees, cleaning, and catering. Treat this as provider-dependent and read the definition section rather than assuming.
OHR is designed to track the costs that rise when the aircraft flies: fuel burn, maintenance wear, and maintenance reserves. If you want the underlying terms defined in plain language, the fractional ownership glossary covers occupied hours, block hours, reserves, and service areas.
Typically included in OHR | Why it's included |
|---|---|
Fuel or a fuel portion | Burn rises directly with flight time |
Scheduled maintenance and inspections | Driven by hours and cycles flown |
Engine reserves | Overhaul costs accrue per flight hour |
Parts reserves | High-value components wear with use |
Tires and brakes | Consumed through takeoff and landing cycles |
Fluids and consumables | Used up on every flight |
Cabin cleaning and turn costs | Tied to each trip (provider-dependent) |
Routine landing fees | Some programs fold these into the rate (provider-dependent) |
Standard catering | Included by some providers within the hourly fee |
Two programs can quote similar OHRs and still invoice very differently. The reason is simple: extras usually come from conditions the provider cannot predict per hour, meaning weather, international routing, and peak-demand constraints, so they are often billed as pass-through charges.
A good rule of thumb: if a cost changes because you fly (fuel burn, maintenance wear, engine reserves), it is often in the occupied hourly rate; if it changes because of weather, geography, timing, or policy (de-icing, international handling, peak-day rules, taxes), it's often an add-on.
Fuel surcharge or fuel variable. Many programs separate fuel into a monthly variable that moves with market prices. Flexjet references a fuel component adjustment, and NetJets publishes a variable fuel rate alongside its base pricing. A fuel surcharge can swing your effective cost meaningfully across a year.
De-icing. Weather-driven, event-based, and airport-specific. A single winter departure can add a de-icing charge that never appears on a summer invoice.
International fees. Landing, handling, parking, overflight, permits, and navigation charges are frequently passed through at cost, and they vary by country and currency.
Peak-day rules. In private aviation programs, "peak days" are provider-defined high-demand calendar days when extra booking rules, restrictions, or price adjustments may apply. Private Jet Card Comparisons notes that peak days can mean longer required lead times, and that a provider may shift your departure window. A peak-day surcharge or a tighter booking rule can apply differently across a share versus a card, so read the exact policy.
Repositioning or ferry fees. Some programs waive ferry charges within a defined service area, then apply a repositioning fee outside that area. NetJets, for instance, markets a no-ferry-fee approach within its service region. A repositioning fee on a one-off trip to a remote airport can rival an hour of flight cost.
Taxes. U.S. Federal Excise Tax of 7.5% can apply to applicable flight charges and commonly shows as its own invoice line. Do not assume the occupied hourly rate is "all-in": many programs include a base operating fee but apply a separate fuel variable and add Federal Excise Tax (7.5% on applicable U.S. flight charges) on top.
Because inclusion and exclusion are defined in writing, the smartest move is to read the fractional ownership contract before you compare headline rates.
Usually extra | Why it's billed separately | How it's priced | Question to ask |
|---|---|---|---|
Fuel surcharge / variable | Fuel prices move constantly | Per hour or monthly adjustment | How often does it reset? |
De-icing | Weather-driven and airport-specific | Per event | Is it capped or full pass-through? |
International fees | Third-party airport and government charges | Pass-through | What margin, if any, is added? |
Peak-day surcharge | Demand spikes on set dates | Per trip or rule change | Can I see the peak-day calendar? |
Repositioning fee | Aircraft flown empty to reach you | Per ferry hour | Where does the service area end? |
Federal Excise Tax | Statutory U.S. tax | 7.5% of applicable charges | Which subtotal is taxed? |
Same words, different definitions. Always verify the contract's definition of OHR or OHF before you trust a comparison. Here is how three well-known names structure the mechanics that actually move an invoice.
NetJets. Its public breakdown separates three components: a monthly management fee, an occupied hourly fee, and a variable fuel rate. NetJets also markets a no-ferry-fee position within a defined service area. A service area is a provider-defined geography where certain fees (like repositioning or ferry charges) may be waived or priced differently. Our deeper NetJets cost breakdown unpacks each of these lines.
Flexjet. Flexjet states that its occupied hourly rate is charged for each hour in flight plus an additional 2/10 of an hour of taxi time, and that the rate covers direct operating costs. Flexjet also references a fuel component adjustment, which functions as a separate fuel variable.
PlaneSense. PlaneSense is often referenced as a differentiated fractional operator with a turboprop and PC-12 focus, so its fleet and mission assumptions can differ from the jet-only programs. Treat it as an example of a niche model rather than a like-for-like rate comparison, since a light jet such as the Phenom 300 serves a different mission than a single-engine turboprop.
Headline OHR is not comparable across brands until you normalize it. When comparing providers, normalize the rate: (occupied hours + taxi adders) × OHR, then add fuel variables, taxes, and pass-through fees.
"The easiest way to evaluate any fractional proposal is to ignore the marketing headline and examine the invoice instead. When every charge is categorized as included, contract-dependent, or billed separately, comparing providers becomes far more objective and buyers are much less likely to be surprised after signing."

This is a simplified, illustrative example, not a quote. Your contract controls. The mission is a domestic U.S. one-way trip on a midsize jet: 2.3 occupied hours plus a 0.2-hour taxi adder, structured the way some providers bill.
Line item | Units | Rate | Amount | Tag | Notes |
|---|---|---|---|---|---|
Occupied hourly rate (base) | 2.3 hrs | $4,800 | $11,040 | IN OHR | Wheels-up to wheels-down time |
Taxi-time adder | 0.2 hr | $4,800 | $960 | CONTRACT-DEPENDENT | Fixed taxi time per leg in some programs |
Fuel variable / surcharge | 2.5 hrs | $600 | $1,500 | USUALLY EXTRA | Separate fuel component in many programs |
De-icing | 0 events | – | $0 | USUALLY EXTRA | Weather-driven, none this trip |
International fees | – | – | $0 | USUALLY EXTRA | Domestic trip, none apply |
Taxable subtotal | – | – | $13,500 | – | Flight charges plus fuel |
Federal Excise Tax | 7.5% | – | $1,012.50 | USUALLY EXTRA | Applied to applicable U.S. flight charges |
Total | – | – | $14,512.50 | – | One-way trip total |
Now the reveal. Effective hourly cost is your total trip cost divided by occupied hours, after adding fuel variables, taxes, and common surcharges. Divide $14,512.50 by 2.3 occupied hours and you get roughly $6,310 per occupied hour on a trip advertised at a $4,800 rate. The fastest way to sanity-check a fractional invoice is to divide the total trip amount by occupied hours, then compare that effective hourly cost to your contract's advertised OHR.
Your monthly management fee is not on this per-trip invoice, but it exists and it raises your true cost per hour, which the next section handles. For a reality check against pay-as-you-go pricing, compare this total to current charter rate benchmarks for the same aircraft class.
To compare two programs, you must convert everything to the same unit: dollars per occupied hour. Follow five steps.
Annualize fixed costs. Multiply the monthly management fee by 12. The monthly management fee is the fixed monthly charge in a fractional program that covers ongoing overhead like crew staffing and training, insurance, hangar, and administration, due whether you fly or not.
Allocate fixed costs across expected hours. Divide those annual fixed costs by the hours you actually expect to fly (about 50 for a 1/16 share, 100 for a 1/8 share, 200 for a 1/4 share).
Add variable cost per hour. Sum the occupied hourly rate, any fuel variable, and a conservative placeholder for average pass-through fees. Replace the placeholder with real contract data as soon as you have it.
Add taxes. Apply Federal Excise Tax where it applies (7.5% of taxable charges).
Add acquisition economics (optional). Take (purchase price minus estimated exit value), divide by contract term years, then divide by annual hours. Remember that exit value is formula-driven, not open-market priced, so read up on fractional share depreciation before you assume recovery.
The compact formula: Effective hourly cost ≈ (annual fixed fees ÷ annual occupied hours) + variable hourly charges + applicable taxes and pass-through fees. Run a quick illustration for a 1/8 share. If a monthly management fee is $22,000, that is $264,000 a year. Across 100 occupied hours, fixed cost adds $2,640 per hour. Stack a $4,800 rate plus a $600 fuel variable, and your pre-tax effective cost is about $8,040 per hour, far above the advertised number. NetJets' published component framing (management fee, occupied hourly fee, variable fuel rate) is a useful template for gathering these inputs.
"The most useful pricing metric isn't the advertised occupied hourly rate, it's the effective hourly cost after allocating fixed management fees, fuel adjustments, taxes, and other variable charges across the hours you actually fly. That's the number that determines whether a program is truly competitive."
- Justin Crabbe, CEO
Input to gather | Where to find it | Why it matters |
|---|---|---|
Monthly management fee | Proposal / management agreement | Multiply by 12 for annual fixed cost |
OHR or OHF | Rate sheet | Confirm taxi adder and minimums |
Fuel variable | Fuel clause / monthly notice | Ask how often it resets |
Peak-day rules | Program policy and calendar | Affects both access and price |
Minimum billable time | Definitions section | Short legs can bill more than they fly |
Taxes | Sample invoice | FET and any segment fees |
The best pricing model depends on how many occupied hours you will reliably fly. Fractional pricing can look cheaper per hour, but jet cards and charter can be more economical at lower or inconsistent annual hours because they avoid monthly management fees and capital lock-up.
Fractional ownership gives predictable access under a multi-year term, and you carry capital, a monthly management fee, an occupied hourly rate, and contract exit mechanics. A jet card is a prepaid or subscription-based private aviation program that provides access at fixed or semi-fixed rates without equity ownership, monthly management fees, or resale exposure. On-demand charter is trip-by-trip market pricing with no commitment and more price volatility. If you want the basics, start with our primer on what is charter.
Industry cost breakdowns, including a detailed Jettly pricing analysis, frame these ranges broadly, so use them as market context rather than fixed quotes. Your decision triggers are reliability of access, exposure to peak travel, willingness to lock capital, and how often you need to switch aircraft categories.
Annual hours | Fractional | Jet card | Charter | Best-fit notes |
|---|---|---|---|---|
50 (≈1/16 share) | Capital + MMF + OHR + exit mechanics | Prepaid hourly, no MMF | Market per-trip | Card or charter often simpler at low use |
100 (≈1/8 share) | Capital + MMF + OHR, multi-year term | Higher per-hour, no capital | Volatile pricing | Fractional gains ground with steady use |
200 (≈1/4 share) | Lower effective $/hr, nears whole ownership | Large prepay required | Availability risk at volume | Fractional usually most competitive |
If you only do one thing: ask for a sample invoice and the definition section of the agreement. If a proposal only shows acquisition cost and an occupied hourly rate, you still need four missing pages: definitions, fuel variable, peak-day rules, and exit/resale terms.
Where OHR or OHF is defined, and what "occupied time" actually means.
Taxi-time adders and the minimum billable time per leg.
Fuel treatment: included, variable rate, or fuel surcharge, and how often it resets.
Peak days: the definition, booking rules, and whether price or availability changes. Private Jet Card Comparisons notes peak days can lengthen lead times and shift departure flexibility.
Service areas and the repositioning fee logic outside them.
International fee handling and pass-through treatment.
The escalation clause, which is a contract provision that allows program rates or fees to increase over time based on defined indices or cost drivers such as fuel, labor, training, or insurance, and whether it hits the OHR, the monthly management fee, or both.
Structure matters here too. Most fractional programs operate under FAA Part 91 Subpart K, and charter operates under Part 135, which changes some invoicing terminology. Our explainer on Part 91K rules adds the regulatory context behind these terms.
Item to verify | Where it appears | Why it matters |
|---|---|---|
OHR/OHF definition | Contract definitions | Sets what occupied time means |
Taxi adder and minimums | Definitions / rate sheet | Raises billed hours on short legs |
Fuel treatment | Fuel clause | Included vs variable vs surcharge |
Peak-day policy | Program calendar | Affects access and price |
Service area and ferry logic | Service agreement | Repositioning fee outside the area |
Escalation clause | Main contract | Annual increases to OHR or MMF |
A fractional occupied hourly rate typically covers direct operating costs that scale with flight time, such as fuel, routine maintenance, and engine and parts reserves, while some taxes and surcharges may be billed separately depending on the contract. Common inclusions are fuel or a fuel portion, scheduled maintenance, engine reserves, parts reserves, tires and brakes, and consumables. Always verify whether fuel sits in the base rate or is billed as a separate variable.
Common "extra" charges include fuel variables and surcharges, de-icing, international landing, handling and overflight fees, repositioning outside service areas, and taxes like Federal Excise Tax. Many airport and international fees are passed through at cost, and peak-day policies vary by provider and by product, so the same trip can invoice differently across two programs.
Sometimes, but many programs publish a base occupied hourly rate and then apply a separate fuel variable or adjustment, so you must verify the fuel clause in the proposal and contract. NetJets publishes a variable fuel rate as a distinct component, and Flexjet references a fuel component adjustment. A fuel surcharge that resets monthly can move your effective cost across the year.
An occupied hour is a billable flight hour when passengers are onboard, and it's the time unit used to apply the occupied hourly rate in most fractional programs. Some providers add taxi minutes per leg on top of in-flight time. Flexjet, for example, references an added 2/10 of an hour of taxi time per leg.
Peak days are provider-defined high-demand dates that can come with stricter booking rules, limited flexibility, or different pricing depending on the program. Peak days are provider-defined high-demand dates; always ask for the peak-day calendar and the exact rule set that applies to your specific program. The definition varies by provider and by product, so a share and a jet card from the same company can treat peak days differently.
Often no. Federal Excise Tax is commonly shown as a separate line item on U.S. invoices and applied to applicable flight charges at 7.5%. The safest approach is to assume taxes are extra unless your contract explicitly states they are included in the rate.
Yes. Monthly management fees are typically fixed charges due regardless of flight activity, because they fund ongoing overhead like crew staffing, training, insurance, hangar, and program administration. That is why underutilizing a share can sharply raise your effective hourly cost.
Compute your all-in hourly cost by dividing annual fixed fees (monthly management fees and any annualized ownership cost) by your annual occupied hours, then adding the occupied hourly rate, fuel variables, taxes, and expected pass-through fees. A 1/16 share flying about 50 hours spreads fixed costs across fewer hours than a 1/4 share flying 200, so the same rate sheet produces a very different effective hourly cost depending on utilization.
Charges in this guide are sorted into three buckets, IN OHR, USUALLY EXTRA, and CONTRACT-DEPENDENT, based on published provider terminology and standard fractional contract structures. The sample invoice uses illustrative rates for a midsize domestic trip and is meant to be replicated with your own numbers, not treated as a quote. FractionalJetOwnership.com evaluates programs by structure over branding and does not represent real-time pricing.
The occupied hourly rate answers one question, "what does an hour of flying cost," and it deliberately excludes the fixed and conditional charges that decide your real spend. Read the definitions, isolate the fuel mechanism, price the peak-day and repositioning fee rules, and convert everything to dollars per occupied hour before you sign anything.
