Empty legs, real savings and their limits
Why aircraft fly without passengers, what an empty leg can save you, why it can vanish at short notice, and what to check before you book one.
Every one-way charter leaves an aircraft somewhere it may not want to be. When it flies home, or on to its next job, without passengers, the operator has a flight it must make anyway, and selling that flight recovers part of the cost. That is an . The savings can be real. So are the conditions attached to them.
Why empty legs exist
Charter aircraft have a home base, where crews live and maintenance is planned. After a one-way trip the aircraft has to return there or travel to wherever its next client is waiting. Each of these positioning flights costs fuel, fees and crew time whether anyone is on board or not.
When the original client has paid for a one-way charter, the cost of the flight home is either already in that price or a cost the operator carries itself. In both cases any revenue from the empty flight is welcome. The same applies when an aircraft positions out to collect a client: the outbound flight to pick them up may be offered too.
What the saving looks like
There is no fixed discount and nobody sets one centrally. The logic is simple: the operator’s alternative is to fly the leg with nobody aboard, so any price above the extra cost of carrying passengers (passenger fees, handling, catering and taxes) improves its position. How far it will go depends on how close the departure is and how likely another buyer seems.
An indicative example, using the middle of our midsize jet band, EUR 5,900 per hour before VAT. You want to fly one way for 2 hours on a route where the only suitable aircraft is based at your destination. As a conventional charter, the operator bills its to your departure airport plus your flight: 5,900 × 2 = EUR 11,800 for each leg, EUR 23,600 in total.
Now suppose the same aircraft is already at your departure airport after dropping off another client, and must fly home anyway. If the operator offers that empty leg at the hourly rate for your 2 hours alone, you pay EUR 11,800 plus fees, half the conventional price. This is an illustration, not a typical discount. Offers close to departure can be lower still, because an unsold empty leg earns nothing.
Empty legs also shape ordinary quotes. An operator that expects to sell the return of your aircraft may quote your one-way trip without the full cost of the flight home. Asking whether that return is already sold or committed elsewhere is a fair question, and the answer can change the price.
The main limitation, the schedule is not yours
An empty leg exists only because someone else booked the original flight. If that client moves the date, changes the destination or cancels, the empty leg moves or disappears with it. The operator’s first obligation is to the client of the main trip, not to you.
Empty leg terms usually allow the operator to cancel or reschedule if the main trip changes, typically with a refund of what you paid and nothing more. You therefore need a : an airline ticket you could still buy, or a conventional charter you are prepared to pay for.
- Time. The departure is set by the next job, usually within a narrow window. A small shift is sometimes possible, a different day rarely.
- Airports. Departure and arrival are fixed. A nearby alternative may be possible, but extra flying is billed.
- Aircraft. You take the type that happens to be free, with its seats and luggage space, not the one you would have chosen.
- Direction. Empty legs are one-way by nature. A matching return on your date is a matter of luck.

Who empty legs suit
Empty legs suit travellers whose plans can bend: people with a few free days, a second home they can reach on a Thursday as easily as a Friday, or a return already arranged by other means. They work well for short notice leisure trips and for anyone living near a busy business aviation airport, where more aircraft pass through.
They suit almost nobody whose trip is fixed. A board meeting, a wedding or a connection to a long-haul flight is a poor match for a seat that can be withdrawn the evening before.
How to find them, and what to check
Operators and brokers publish empty legs on their own lists, in newsletters and in apps, and many will watch a route for you if you tell them where and when you could travel. Expect to decide quickly, because an attractive offer on a popular route may not stay available for long.
Before you pay, treat the flight exactly as you would a full-price charter. An empty leg booked properly is a normal commercial charter flight: the same operator, the same (AOC), the same crew duty rules and maintenance standards. Once paying passengers are aboard, the leg must be operated as a commercial flight under that certificate.
- Ask for the name of the operator and its certificate, not only the broker’s.
- Read the cancellation and rescheduling terms, including what is refunded.
- Confirm what the price includes: fees, taxes, catering and luggage limits.
- Check the seats and baggage space against your group before you commit.
A price that looks too good on an aircraft offered directly by a private owner or a pilot is a warning sign, not a bargain. Paying passengers belong on properly certificated flights, whatever the price.

Questions readers ask
Is an empty leg less safe than a normal charter?
No, provided it is booked with a properly certificated operator. The aircraft, the crew, the duty time rules and the maintenance standards are the same as on any other commercial flight that operator sells. The discount reflects the flight’s timing, not lower standards. Check the operator exactly as you would for a full-price trip.
Can I book a return on an empty leg as well?
Rarely as a pair. Empty legs follow other clients’ trips, so a matching flight back on the day you want is a matter of luck. Most travellers who use them book the return separately, on an airline or as a conventional charter, or simply travel when both directions happen to appear.
Can the departure time of an empty leg be changed?
Only within the limits the operator sets. The aircraft has to reach its next client on time, and the crew’s duty and rest are already planned around that. A small shift is sometimes possible. A different day or airport usually is not, or only at the price of extra flying.
