Empty leg
An empty leg is a flight an aircraft has to make anyway with nobody on board, usually to return to base or reposition for its next paying customer. Operators sell these sectors at a discount, often 25–75% below a normal one-way quote, because any revenue beats flying empty. The catch is flexibility: the date, route and aircraft are fixed by someone else's trip, and if the original booking changes or cancels, your empty leg can vanish with little notice. Treat empty legs as a bargain for travellers with loose plans and a fallback option, not as a dependable way to make a fixed meeting or a wedding.

Check the bargain against the whole trip
An empty leg depends on another aircraft movement. A low advertised price is only useful if the trip still works when that movement changes.
Before accepting an offer
Ask for the exact sector, aircraft, departure window, total price, allowed changes and cancellation treatment. Confirm whether the onward and return travel remain your responsibility and what the provider will do if the underlying flight changes.
Keep a workable fallback
Compare the empty leg plus hotels, ground travel and a replacement flight with a normal one-way proposal. Do not use an unconfirmed empty leg as the only way to reach a fixed meeting. JetAtlas does not list live empty-leg inventory.
