Guide
The same flight goes by half a dozen names depending on who is talking. Here are the ones you will meet, what they mean, and where on this site each one is answered with a number rather than a definition.
Updated . Board figures from September 2026. The live list on the home page is live.

A flight a charter aircraft has to make with nobody in the cabin, sold at a discount. The operator sets the route, the date and the aircraft. One way, no return. Everything on the live list is one.
The crew and broker word for the same thing, more common in the United States. An aircraft deadheads when it flies a sector without paying passengers. Explained at length in deadhead flights.
Another name for an empty leg, used by some brokers to mean a positioning sector that is open for sale. Same flight.
What the operator calls the empty sector internally: moving the aircraft to where the next booking starts, or home to base. Ferry flight is the same idea, usually for maintenance or delivery. When one is offered for sale it becomes an empty leg.
Not sold on an empty leg. The operator sells the whole aircraft, so an empty seat on a private jet is not a product here. The per seat figures on this site are arithmetic, the listed price divided by the listed seats, and only hold if a group fills the cabin. See how much an empty leg private jet costs.
What a card says when the operator published no price. We print that rather than guess. It is the majority of the board: 848 of the 1,091 upcoming legs when we read it in September 2026, and 24 of 677 in the United States carried a figure.
The operator's own published figure for the whole aircraft, one way, shown exactly as written. Never per seat, never a from price.
The listed price divided by the listed seat count. A division, not a fare. The median on our board in euros is 622, on a Citation with nine seats.
A company that holds the air operator certificate and flies the aircraft. Everything on this site comes from operators publishing their own legs. We do not read brokers.
A company that sells flights on aircraft it does not operate, taking a margin. We are not one: no commission, and the enquiry goes to the operator that flies the leg. Broker sites are why a search for empty legs returns so many pages with no actual flights on them.
An email when an operator publishes a leg on a route you chose. Useful because close to half of the legs we record appear inside the final week before departure. Set one on the home page.
What happens to most empty legs. We have watched 622 disappear from operator sites before their departure date, half inside 4.5 days of appearing and 54 inside 24 hours. A listing is a strong indication, not a guarantee.
None in practice. Empty leg is what operators write, deadhead is what crews and American brokers say. Both mean a private aircraft flying a sector with nobody in the cabin, sold at a discount.
The operator published the flight without a price, so you ask them and they quote. On our board that is 848 of 1,091 upcoming legs; where a price is published we show it exactly as listed.
A broker's name for an empty leg: a positioning sector that is open for sale. Same flight, same rules, one way.
