Empty-Legs Are Not the Deal You Think They Are, and the 3 Times They Actually Are

Empty-leg listings are the closest thing private aviation has to a viral marketing hook. Every operator publishes them, every affiliate site aggregates them, and the pricing looks unbeatable. The problem is that fewer than one in ten of the empty-legs advertised online in a given week actually completes as advertised. Here is what the number really means and when it is worth chasing.

What an empty-leg actually is

An empty-leg is a positioning flight. A client charters a jet from A to B, and the operator has to move the aircraft back to base (or forward to its next paying trip). That reposition has no passenger revenue attached, so the operator would rather sell it at any margin above fuel plus crew than fly it empty. Advertised empty-leg prices are typically 40 to 70 percent below a regular charter for the same route.

Why they usually fall through

Three structural reasons:

• The primary trip changes. The paying charter that generated the empty-leg is booked first. If those passengers push a day, cancel, or add a stop, the empty-leg vanishes or shifts by 24 to 48 hours. Empty-leg buyers are always second in line.
• The route is fixed and non-negotiable. The aircraft is going from A to B on a specific day and specific time. You cannot shift departure by two hours or leave from a nearby airport. If your calendar does not match exactly, the deal is not for you.
• Two hours of ground time can kill it. Many advertised empty-legs are only economic if the operator can complete the leg in a specific window. Slot restrictions, curfews, and crew duty limits shrink that window. By the time you call, the operator has often already moved the aircraft.

The three times empty-legs actually work

1. You have a flexible date and a common repositioning corridor

The most reliable empty-leg corridors in Europe are Nice to Le Bourget, Farnborough to Nice, Geneva to Le Bourget, and Palma to Farnborough. These are corporate weeknight repositions that repeat with predictable frequency. If your date has a 3 to 5 day window and the corridor matches, you can genuinely book at 50 to 65 percent off. The trick is to submit your window to two or three operators at once and let them tell you which day works.

2. You are willing to book same-day or day-before

The best empty-leg deals are the ones the operator did not think would sell. If a Sunday reposition from Ibiza back to Le Bourget goes unsold by Saturday morning, the operator will discount aggressively rather than fly empty. A same-day booking on a well-known repositioning route can be 70 percent below list. You need to accept that the deal only appears at 24 to 48 hours out and be ready to move.

3. Group of 4 to 6 on a short-haul light jet

Empty-leg pricing scales the same as full-charter pricing: per aircraft, not per seat. A 6,000 EUR empty-leg costs the same for one passenger as for six. On a short-haul light jet with a group of four to six, the per-passenger cost can genuinely undercut business-class commercial fares on the same route. This is where empty-legs shine.

How to actually shop them

Do not book from a public listing. Public empty-legs are the leftover pool that has already been shopped by every broker on that operator's list. The good empty-legs never make it to a public page. What works: pick two or three brokers you trust and tell them your window and passenger count. Ask them to watch the market for repositions matching your parameters. They can flag deals within an hour of the operator releasing them, and often before a public page even gets updated.

The realistic expectation

Treat empty-legs like standby airline seats. They exist, they are real, they save real money, but they only work for travellers who can absorb schedule risk. If your trip has a fixed meeting time or a fixed return date, you are better off paying list and being confident the aircraft will be there.
