Empty Leg Flights: How They Work, What Goes Wrong

What an Empty Leg Is

A private jet drops its passengers in Nice. Its base is Geneva. It has to fly home regardless, because that is where tonight's next booking starts. That Geneva-bound sector with nobody on board is an empty leg, and the operator would rather sell it cheap than fly it with warm air.

The scale of this surprises people. Around 40% of all business aviation sectors in Europe fly empty, according to European Business Aviation Association industry data. Thousands of jets cross the continent every day carrying no one. That is the inventory behind the discounts.

What You Actually Pay

Empty legs publish at 30 to 90% below the standard charter rate. The range is wide because pricing depends on how desperate the operator is and how soon the flight leaves. Some real numbers from 2026 listings:

(The first four are real GlobeAir listings from spring 2026 on their Citation Mustang fleet; the London routes are typical broker quotes for light jets.)

Three things about the price. You are buying the whole aircraft, so a €1,390 leg splits into €350 per head if you can find three friends. The price covers the flight as published; catering, de-icing and ground transfers bill separately. And long-haul empties exist too: London to New York or Dubai repositioning flights get listed from around £30,000 to £60,000 depending on aircraft, which sounds less impressive until you compare it with the £100,000-plus standard quote for the same Gulfstream.

Why Nobody Gets a Bargain Route They Wanted

Here is the structural catch, and it explains almost everything about this market. Empty legs follow other people's itineraries. Popular charter flows create popular empty legs, but they point the opposite way: the jet flies full to the Mediterranean in July, and the empties run back north. If your dream is London to Nice on a Friday morning in peak season, you are chasing the wrong end of the trade lane.

What shows up instead, week after week:

• Midweek repositioning between secondary cities (Lugano, Linz, Antwerp, Jersey)
• Sunday evening returns toward London after weekend charters
• Post-event legs out of Nice, Palma and Olbia early in the week
• Odd one-offs that fit somebody's calendar by luck

If you treat the list as a menu of possibilities rather than a search box for your exact plan, the market starts working for you.

The Cancellation Risk, Stated Plainly

Your flight is a by-product of someone else's booking. When their plans change, yours change. The main scenarios:

They move the flight. Your 09:00 becomes their new 14:00, which becomes your 14:00. Operators usually give notice, but notice can be hours rather than days.

They cancel. The reason for the repositioning vanishes. So does your leg. This is most likely close to departure, which is precisely when you have built a weekend around the flight.

They extend. The original client adds a return trip on your sector, the jet stops being empty, and you get a call.

Good operators and brokers rebook you on something comparable or refund fast. Bad ones slow-walk the refund while your hotel fills up. Either way, the practical defences are the same: keep plans flexible within a day either side, book refundable rates, and never build a non-refundable sequence (wedding, connection, cruise) onto an empty leg. We tell clients to think of empties as a bonus flight, not the plan itself.

One more rule: confirm who operates the aircraft before you pay anyone. You want the operator's Air Operator Certificate number, not just a slick website. This matters more on discounted deals than standard bookings, because resale platforms pile into this end of the market.

Booking One: The Sequence

For those hunting their own leg rather than waiting for us to flag it, the process that works:

1. Define the corridor, not the flight. "London to Geneva area, any date this Friday-to-Sunday window" catches three times as many opportunities as a fixed request.
2. Register with two marketplaces and one operator list. Coverage overlaps less than you would hope; GlobeAir's own fleet legs never reach Victor's board, and vice versa.
3. Move within hours on anything good. Ask what holds the aircraft and for how long. Reputable sellers give you a written option of 24-48 hours; anything held verbally past lunch is probably gone.
4. Confirm the operator's AOC and tail number in writing, along with cancellation terms: what happens if the leg moves or dies, refund timeline, rebooking rights.
5. Pay by card where possible. Chargeback protection beats bank transfers when a platform folds between payment and departure, which has happened.

Practicalities People Forget to Ask

Empty legs carry the same rules as any charter plus a few of their own:

• Luggage follows the aircraft type, not the discount. A Mustang swallows four soft bags, not four hard suitcases and golf clubs. Check hold dimensions before celebrating the price.
• Catering is usually basic or absent at these prices. Fine for a 90-minute hop; worth arranging for anything longer.
• Pets need explicit approval even on operators that normally allow them, since the empty leg may chain into another client's flight same-day.
• Timing is exact. There is no "the captain will wait" on a leg built around someone else's schedule; arrive at the FBO thirty minutes before wheels-up or watch your bargain taxi out without you.
• Passport validity rules apply identically to scheduled aviation; a discounted boarding does not soften border formalities.

None of these kill the deal. All of them surprise somebody every week.

Where the Legs Are Listed

No single source sees everything. Operators publish their own legs, brokers aggregate across fleets, and a few indexers scrape the public lists. The ones worth knowing:

• GlobeAir publishes its own Mustang fleet's legs with confirmed prices and even probability scores on unconfirmed flights
• Victor lists transatlantic and intra-Europe empties with fixed pricing through a broker layer
• XO (Vista Global's app) carries guaranteed empty-leg pricing plus seat-sharing options
• The Empty Leg Index aggregates openly published legs across UK and Europe and links straight to each seller
• Operators' mailing lists: many mid-size charter firms email their legs weekly, and the good ones sell out internally before anything reaches a marketplace

Listings refresh constantly and the decent ones vanish in hours, not days. A leg that sits unsold for a week usually has something wrong with it: brutal timing, awkward airfield, or a seller fishing.

How We Use Them For Clients

Sulu monitors empty legs as part of our private aviation service. Tell us your corridors (London to Geneva, say) and rough dates, and when a matching leg appears we check the operator, confirm the cancellation terms, and message you the deal with a plain-English risk note. If the timing works, a €1,400 hop beats a €400 airline seat and a five-hour door-to-door slog. When it does not work, we will say so and book the boring option instead.
