Fixed vs variable costs of running a private jet
Updated
Almost every argument about whether a jet is expensive is really an argument about utilization. Split the ledger properly and the argument settles itself.
The two ledgers
Fixed costs are incurred because the aircraft exists. They accrue on a Sunday when nobody flies. Crew salaries, hangarage, insurance, the management company's monthly fee, navigation and weather subscriptions, connectivity and the fixed element of maintenance programmes all sit here.
Variable costs are incurred because the aircraft flew. Fuel, hourly maintenance and engine reserves, landing and parking fees, handling, catering, crew hotels and ground transport all sit here. Some of these accrue per hour and some per landing, which is why average trip length changes the answer.
The cost drivers, line by line
| Cost line | Fixed or variable | What actually moves it | What to ask a vendor for |
|---|---|---|---|
| Flight crew | Fixed | Crew complement required by the type, whether you carry a dedicated crew or share, duty and rest rules, recurrent training cycle, local pay market | A written crew cost including payroll taxes, benefits, recurrent training and contract cover for leave and sickness |
| Hangarage | Fixed | Airport, aircraft footprint, whether space is dedicated or communal, whether de-icing and towing are bundled | The annual rate, the term, what happens at renewal, and what is included beyond the floor space |
| Insurance | Fixed | Hull value, liability limits, crew experience on type, geographic use, claims history, the state of the market that year | A quote showing hull and liability separately, with the pilot warranty and territorial limits spelled out |
| Management fee | Fixed | Scope: whether it covers crew employment, maintenance oversight, scheduling, accounting, regulatory compliance | A scope schedule listing what is in the fee and what is billed at cost or with a markup |
| Fuel | Variable, per hour | Burn rate for the type, mission profile and altitude, uplift price at the FBOs you actually use, fuel programme or contract pricing | Your negotiated into-plane price at your home base and your top five destinations, not a national average |
| Maintenance and engine reserves | Variable, per hour | Type and age, programme coverage, whether engines are enrolled, escalation clauses, unscheduled events | A programme quote with the hourly rate, what is covered, what is excluded, and the annual escalation |
| Landing, parking and handling | Variable, per landing | Number of legs rather than hours, airport class, weight, time of day, whether an FBO waives fees against fuel uplift | A schedule of fees at your regular airports and the fuel uplift that waives handling |
| Catering, crew hotels, ground transport | Variable, per trip | Trip length, overnights away from base, passenger expectations | A typical trip expense recap from a comparable operator, not an average |
Why the per-hour number is close to meaningless on its own
A quoted cost per hour is only a description of an assumed utilization. Our data table holds every unit cost constant and varies annual hours: the all-in hourly cost falls from $13,208 at 50 hours a year to $3,399 at 600. Nothing about the aircraft changed. If someone quotes you an hourly operating cost without stating the annual hours behind it, the number is not comparable to anything.
