How Do Empty Leg Flights Work? A 2026 Buyer's Guide
Empty leg flights are the only legitimate way to fly private at retail-discount prices. They're not a marketing label and they're not a loyalty perk — they're a real product driven by a structural mismatch between where operators have aircraft and where customers want to fly. This guide walks through the supply-chain mechanics that create empty legs, the pricing math that drives discount depth, the booking trade-offs you accept in exchange for the discount, and the practical playbook for finding them on a live marketplace.

Where empty legs come from
Every paid private jet charter is a one-way trip from the aircraft's point of view. An operator quotes a customer from Teterboro to Aspen; the aircraft has to get to Teterboro to start the trip and has to get back to its base — or to its next booking — after the customer disembarks in Aspen. Those positioning segments are flown empty by default. Each one is a candidate to be sold as an empty leg.
Operators decide on a flight-by-flight basis whether to publish the positioning leg as an empty leg. The factors: How firm is the originating booking? How long is the gap between the empty leg and the next paid trip? Is the route popular enough to expect demand at a discount? Most operators publish 30–60% of their positioning legs; the rest stay internal because the schedule is too tight or the routing is too unusual.
Once an operator authorizes a positioning leg as an empty leg, the leg appears in the operator's own booking system, on aggregator marketplaces like SkyAccess, and sometimes on industry messaging boards (Avinode, Stratos). The leg stays available until it's booked, cancelled, or the departure window closes.
Why empty legs are discounted
The operator's fixed costs on a positioning leg are committed the moment the originating booking is signed: crew duty hours, positioning fuel, landing and ramp fees, handling, insurance for the segment. Those costs exist whether the aircraft flies empty or full. Anything the operator can recover by selling the empty seats is contribution margin against a sunk cost.
That economic reality is why empty-leg pricing isn't anchored to retail charter pricing. The price floor is closer to fuel + landing fees than to the operator's all-in retail rate, which is why same-aircraft, same-route empty legs can land 60–80% below the operator's own on-demand charter quote on the same day. The depth of the discount is a function of how badly the operator needs to recover the leg cost, and how close to departure the leg is.
Discount depth scales inversely with time to departure. A leg published 14 days out at 50% off retail will often clear at 70% off if it's still unsold 48 hours before departure. Some operators automate this with dynamic pricing rules; others reprice manually as the window closes. Either way, the cheapest empty legs are the ones closest to taking off — which is why the marketplace inventory turning over inside 72 hours is where the deepest discounts hide.
What you trade for the discount
Empty leg pricing reflects a trade. The operator decided when the aircraft was leaving and where it was going when they quoted the originating booking. The empty-leg buyer accepts that schedule in exchange for the discount. Three constraints apply.
Departure window. Operators usually publish a 4-24 hour window during which the leg can depart. The exact takeoff time within that window is set by crew availability, weather, and the originating booking's actual landing time. Plan ground transport for the window, not a fixed time.
Routing. The published origin and destination airports are dictated by the originating booking. Some operators will accept minor airport-pair substitutions (e.g. KVNY for KLAX) if the cost is neutral; most won't. Don't book an empty leg unless you can use both airports as published.
Cancellation. If the originating paid booking moves, cancels, or reroutes, the empty leg can be voided with no obligation to the empty-leg buyer beyond a refund. Reputable marketplaces disclose this in writing. Buy a refundable backup option for high-stakes trips.
How to find them
Search a live marketplace that indexes Part 135 operator inventory directly — SkyAccess, AceJet, or operator-direct booking sites. Filter by route, departure date window, and aircraft category. The freshest inventory shows up inside 72 hours of departure, so set saved searches on routes you fly often and have alerts route to email and SMS.
When you find a candidate, verify three things before booking. First, the operator's Part 135 status — every legitimate empty leg is operated by an FAA-certificated Part 135 air carrier. Second, the cancellation policy — specifically the originating-booking-cancellation clause, which is the real risk on an empty leg. Third, the price terms — is what you see the all-in price including fuel surcharge, federal excise tax (FET), and segment fees, or are there add-ons at checkout?
Treat empty-leg shopping like flight shopping in general: the cheapest inventory turns over quickly, the time of week matters (weekend repositioning legs into ski markets in winter, into the Hamptons in summer), and operators reprice as the window closes. Refresh saved searches at least once a day; for high-priority routes, refresh twice daily during the 72-hour window.
Step-by-step: How to book an empty leg flight
Estimated time: 25 minutes
- 1
Search a live empty-leg marketplace
Use a marketplace that indexes Part 135 operator inventory directly. Filter by origin, destination, and date window. The freshest inventory turns over inside 72 hours of departure.
- 2
Verify the operating Part 135 certificate
Every legitimate empty leg is operated by an FAA-certificated Part 135 air carrier. The operator's certificate designator should be visible on the listing.
- 3
Confirm the cancellation policy
Read the originating-booking-cancellation clause. The biggest risk on an empty leg is the originating paid booking moving, which can void the empty leg.
- 4
Confirm the all-in price
The display price should include fuel surcharge, federal excise tax (FET), and segment fees. Ask in writing if you're not sure.
- 5
Book and lock the FBO
Confirm the departure FBO 24 hours before takeoff. Operators sometimes switch FBOs between booking and departure based on fuel and slot allocation.
Frequently asked questions
- How do empty leg flights work?
- Empty legs are positioning flights that an operator has to fly anyway — either to get an aircraft to a paid trip's departure airport or to bring it back afterwards. The operator sells the seats at 25–80% off retail charter to recover the positioning cost. The buyer accepts the operator's schedule and routing in exchange for the discount.
- Why are empty legs so cheap?
- The operator's fixed costs on the positioning leg are already committed by the originating booking. Anything the operator recovers from selling the empty seats is contribution margin against a sunk cost, so prices land near fuel + landing-fee floor rather than retail charter rate.
- Can I change the date or route of an empty leg?
- No — the schedule and routing are dictated by the originating booking. If your dates or route can't move, an on-demand charter is the right product. Empty legs reward flexibility.
- What happens if the empty leg is cancelled?
- If the originating paid booking that created the empty leg moves or cancels, the empty leg can be voided. Reputable marketplaces refund the empty-leg buyer in full. For high-stakes trips, hold a refundable commercial backup.
