The Economics of Empty Legs, From the Operator’s Side

A floating-fleet operator may watch 30 to 40 percent of its flight activity move without passengers. That figure, disclosed by Volato in securities filings for its empty-leg platform, is not a glitch in the charter business. It is part of the machine.

One customer charters a Challenger 350 from Westchester County to Palm Beach. The next paid trip starts in Atlanta. The airplane must move. The crew must be legal for duty time. Maintenance intervals keep counting. The owner may have a view on price. Dispatch has to protect the next client, not just fill two seats on a bargain flight.

To the passenger, the empty leg is a discounted private jet. To the operator, it is perishable inventory with a tail number, a crew pairing, a departure window and a vanishing resale value.

The flight already has a reason to exist

An empty leg is not a cheap charter created for bargain hunters. It is a repositioning sector created by another trip. The aircraft is moving to return home, pick up its owner, start a charter, reach maintenance, or recover from a schedule change.

That distinction drives the economics. The operator is not asking, “What is the normal charter price?” The better question is, “What cash can be recovered without creating new risk?”

On a normal one-way charter, the quoted price often has to cover more than the passenger’s occupied segment. If the aircraft is based elsewhere, the customer may pay for positioning into the departure airport and positioning away after landing. In a floating fleet, where aircraft are not always dragged back to a fixed home base, the model changes, but the deadhead does not disappear. It is simply optimized across a larger network.

Global business jet activity has stayed high by pre-pandemic standards. JETNET’s July 2026 market review, using WINGX activity data, put worldwide business jet departures at 1.95 million in the first half of 2026, up 4.0 percent year over year. North America accounted for 71.8 percent of that activity. Charter operators, however, were not the fastest-growing group: they represented 16 percent of global first-half activity and were down 3.1 percent year over year, while fractional operators and private flight departments grew by more than 10 percent. That matters because empty-leg supply is shaped by who is flying, not just how many flights exist.

The operator’s price floor is not zero

The seductive myth is that any revenue beats none. Operators know better.

Even when an aircraft is going anyway, a passenger-carrying empty leg creates work and liability. A clean ferry flight can depart early, depart late, stop for fuel where convenient, carry no catering, skip passenger handling and use a simpler service plan. Put customers on board and the operator may add catering, ground transport coordination, passenger screening, FBO fees, cleaning, flight following, customer service time and broker commission.

The bigger constraint is disruption. If an empty-leg customer wants the departure moved by three hours, or asks for a different airport 90 nautical miles away, the operator must test that request against the next paid trip. A small change can break crew duty limits, fuel planning or the aircraft’s arrival buffer.

A low price can also create a brand problem. Many charter aircraft are managed on behalf of private owners. NBAA’s Aircraft Operating and Leasing Guide notes that when an aircraft is placed on a Part 135 certificate, the air carrier may pay the owner a fixed fee or a percentage of charter revenue to help offset ownership costs. That owner still has an economic stake in how the airplane is used. Some owners would rather let the aircraft move empty than accept a price that feels damaging to the asset, the cabin or the aircraft’s market position.

Business Jet Traveler made the same point years ago after testing the consumer side of the market: large headline discounts exist, but ordinary empty-leg savings can be much more modest, and flights can vanish when the underlying charter changes. That remains the structural truth.

What the aircraft costs while it moves

Variable cost is the operator’s first reference point, but it is not the whole bill. JetAtlas reference figures show the spread between aircraft types.

Those figures help explain why operators do not price all empty legs alike. A two-hour repositioning sector on a King Air 360 sits in a different economic universe from the same block time on a G650ER. The large-cabin jet burns more fuel, carries higher maintenance exposure and usually brings higher passenger expectations.

The table also leaves out items that may decide the sale: landing fees, handling, international permits, deicing, crew hotels, owner revenue share, broker commission and federal excise tax treatment. It also leaves out fixed costs, which remain whether the aircraft flies or sits: insurance, hangar, training, subscriptions, finance costs and management overhead.

For an operator, the empty-leg price often lands in a narrow band. It must be high enough to justify passenger handling and owner approval, low enough to attract a flexible buyer, and safe enough that a better full-price charter can still take priority if the contract allows.

Why the best empty leg is close to the original route

The cleanest sale is a passenger who wants the aircraft almost exactly where it is already going, at roughly the same time. The worst sale is a traveler who tries to turn a deadhead into a custom charter.

A small diversion can make sense. A flight from Teterboro to Opa-locka might be sold to a customer going to Fort Lauderdale Executive. A repositioning sector from Scottsdale to Van Nuys might tolerate Burbank if the timing works. But every mile away from the planned track chips away at the economics.

Operators usually test four questions before accepting the booking:

• Does the requested airport change the aircraft’s fuel stop, slot, permit or runway plan?
• Does the timing protect the next revenue trip?
• Will the crew remain legal after boarding, passenger delays and post-flight duties?
• Is the net revenue, after commissions and added costs, worth the operational exposure?

If the answer to any one of those is weak, dispatch may keep the aircraft empty. That can look irrational to a shopper staring at an online deal. It is rational to the person responsible for tomorrow morning’s owner flight.

Regulation changes the sale

In the United States, a passenger-carrying charter flight generally falls under Part 135 when sold as on-demand air transportation. The FAA says it grants Part 135 authority for on-demand, unscheduled air service, and its Safe Air Charter material stresses that pilots and operators must meet the rules that apply to the specific operation. The FAA also warns that unauthorized charter remains a national problem.

This matters because not every aircraft movement visible in the market is legally available for charter. A privately operated Part 91 repositioning flight may not be something a broker can simply sell to the public. The operator with operational control, the certificate, the crew assignment and the insurance must line up.

For legitimate operators, compliance adds cost and removes shortcuts. Passenger manifests, crew qualifications, maintenance status, operational control, hazardous materials procedures and dispatch release are not optional because the fare is discounted.

Software has made the board more visible

The old empty-leg market lived in phone calls, broker emails and member-only listings. It has moved toward platforms, alerts and automated matching, though the underlying aircraft remains stubbornly physical.

In September 2024, VOO announced a dedicated empty-leg feature for its B2B charter marketplace, designed to let brokers search by route radius and dates while operators reviewed calculated prices before sending booking offers. Volato’s Vaunt platform, described in 2026 filings, lists empty-leg inventory from Part 135 operators, typically two to five days before departure, and sells access through a membership model.

The software trend is not just about selling cheap seats. For operators, the value is speed. Empty legs decay quickly. A repositioning flight posted five days out may be useful; the same flight three hours before departure is mostly a dispatch fact. Better matching can recover revenue, but it cannot remove weather, crew duty, owner approval or the next trip.

The operator’s real win

The best outcome is not always a sold empty leg. It is a network with fewer awkward ones.

A strong charter desk tries to build chains: owner flight, charter, maintenance stop, charter, owner return. It may accept a lower-margin trip because it places the aircraft near a better one. It may reject a tempting empty-leg sale because the airplane would arrive with no slack before a guaranteed customer. It may discount heavily in one direction in March and barely at all on the same route in April.

That is why empty-leg pricing can look inconsistent from the outside. It is not an airline fare filed into a reservation system months ahead. It is the price of solving a temporary aircraft-location problem.

On the ramp, the difference is plain. A ferry leg can close its door and leave when the crew is ready. A sold empty leg waits for passengers, bags, catering, coffee, ice, a lavatory service truck and a signature. Sometimes that wait is worth the revenue. Sometimes the airplane leaves with only two pilots up front and a quiet cabin behind them.
