What Are Empty Leg Flights and How Do They Work?

What is an empty leg flight?

An empty leg is a private jet segment the operator has to fly without paying passengers, sold off at a discount to defray fuel and crew cost. Every charter flight creates the potential for one: the aircraft has to get to the client's departure airport, and it has to go somewhere after drop-off. If the next revenue trip is somewhere else, the connecting leg is "empty." Rather than eat the full cost, the operator lists the segment — fixed date, fixed route, fixed time — at a steep discount and hopes someone buys it before wheels-up.

The economics are simple. The operator is already paying for fuel, crew duty time, and airport fees on that leg. Anything they collect above the marginal cost of carrying passengers (catering, landing fee differential, a small handling premium) is recovered margin. That's why a TEB-PBI empty leg on a midsize jet that would retail at $22,000-$28,000 as a one-way charter can show up on an aggregator at $8,000-$12,000.

How much do empty legs actually save you?

Empty legs typically discount 30-75% off a comparable on-demand charter, with the spread widening on long-tail routes and short notice and narrowing on dense corridors. A Friday afternoon TEB-PBI light jet empty leg posted 36 hours out might sit at 40% off because demand is thick. The same aircraft repositioning OPF-BED on a Tuesday in August might go for 70% off because nobody is northbound in summer.

The discount also depends on how the operator prices the underlying charter. Part 135 operators with full retail rates produce bigger nominal discounts on empty legs than fractional programs or jet card operators, who often don't release empty legs to the public at all — they route them back into the program as discounted callouts for cardholders.

Where do empty legs come from?

Repositioning. Every charter has an origin and a destination, and the aircraft rarely stays put. The most reliable empty leg producers are the major seasonal corridors. October and November southbound to Florida creates a steady run of TEB-PBI, TEB-OPF, BED-PBI, and HPN-PBI legs as snowbirds reposition. April and May reverse it: northbound returns out of OPF and PBI back to TEB, MMU, and HPN. The ski corridor — ASE, JAC, EGE, SUN — produces predictable Sunday afternoon and Monday morning empty returns to VNY, DAL, and the Northeast after weekend trips. Post-event slack around the Super Bowl, the Masters, F1 Miami, and Art Basel dumps inventory the day after the event ends.

The other source is operator-base repositioning. An aircraft based at SDL that flies a client to VNY has to come home. If the operator can't sell a return charter, the SDL-VNY return becomes an empty leg.

Where do you actually find empty legs?

The public marketplaces are XO, JetASAP, Stratos Jet Charters' empty leg board, and the residual JetSmarter inventory now folded into XO. These aggregate listings from operators who release legs to the open market. The catch is that the best empty legs — clean routes, popular dates, decent aircraft — get bought within hours of posting, often by brokers who flip them to retail clients at a markup.

The faster channel is broker mailing lists. Most established brokers send daily or twice-daily empty leg blasts to their client base before legs hit public aggregators. If you fly a couple of times a year and have a relationship with a broker, you'll see inventory 12-48 hours before XO does. The fastest channel is operator direct: if you know which operators run the routes you fly, calling their charter desk and asking what's repositioning gets you the rawest pricing.

What's the catch with empty legs?

You take the operator's exact route, date, and departure window. The trade falls apart the moment you try to shift either end. Want to leave two hours later? That's a charter, not an empty leg, and the price triples. Want to land at a closer airport? Same problem. Empty legs are sold as-is because the operator has already committed the aircraft to a position at a specific time.

The bigger risk is cancellation. An empty leg only exists because of a revenue charter on either side of it. If the inbound charter cancels, gets pushed a day, or swaps aircraft, your empty leg evaporates. Operators generally refund in full, but they don't owe you a replacement aircraft and rarely provide one at the empty leg price. If you have a hard arrival deadline — a wedding, a closing, a board meeting — empty legs are the wrong product. Book a guaranteed charter.

Aircraft swaps are the other failure mode. You booked a Phenom 300; the operator's scheduling shifted and you're now on a King Air. Reputable operators disclose and offer a refund. Less reputable ones don't.

When does an empty leg actually make sense?

When your schedule is genuinely flexible and the route happens to match an active repositioning corridor. The buyer who wins on empty legs is someone with a second home in Aspen who can fly Sunday or Monday depending on what posts, or a Florida resident who'll take any Tuesday-Thursday return north in April. Flexibility on date is worth more than flexibility on time — most empty legs depart in a two-to-four hour window the operator sets based on crew duty and the next revenue trip.

Empty legs also work for one-way trips where you'd otherwise pay a heavy one-way premium. On-demand charter pricing assumes the operator has to deadhead the aircraft back; if you're buying the deadhead itself, you're cutting out that markup entirely. That's why empty leg pricing on long single-direction routes — say a transcon VNY-TEB — can look dramatically better than a one-way charter quote for the same segment.

What empty legs don't do is replace a jet card or a charter contract. They're opportunistic inventory. Build your travel around them and you'll miss flights. Layer them on top of a primary booking strategy and you'll occasionally fly for 60% off.
