Quick answer
The most reliable way to find an empty leg is a route alert that watches your city pair for you, because inventory appears unpredictably and sells within hours. Searching live listings, working with a broker, and staying flexible on dates and nearby airports all widen what you will catch.
Key takeaways
- Empty legs are perishable: most surface days to weeks ahead and sell within hours.
- A route alert is the single most reliable method because it watches when you cannot.
- Flexibility on dates and nearby airports multiplies the legs you will match.
- A good broker can surface off-market repositioning the public lists never show.
- Sites promising a fixed daily feed of cheap legs are usually selling membership, not flights.
Why empty legs are hard to find
An empty leg only exists because a jet has to reposition — fly back to base, or on to its next booking, with nobody aboard. The operator does not know that trip is coming until the paying charter either side of it is confirmed. So legs do not appear on a tidy schedule. They surface unpredictably, often only days before departure, and because the discount is real they sell within hours of listing.
That is the whole challenge. You are not looking for a route that runs every Tuesday; you are waiting for a specific aircraft to need your specific corridor at roughly your time, and then moving faster than the next person. Refreshing a search page works only if you happen to be looking in the narrow window the leg is live.
The five ways that work
In rough order of reliability:
1. Set a route alert. You tell a marketplace the corridor you want — London to Nice, say — and it emails you the moment a matching leg appears. This is the only method that watches the inventory continuously, which is exactly what perishable, unpredictable supply demands.
2. Search the live marketplace. A search across the global empty-leg marketplace shows what is bookable right now. Useful for a snapshot and for gauging prices, but it only shows the legs live at the moment you look.
3. Work with a broker. Brokers see repositioning that never reaches a public list, because operators often offer it to their contacts first. If your dates are firm and the saving matters, a broker can quietly hunt for you.
4. Watch more than one airport. Legs into Nice might not match, but legs into Cannes–Mandelieu or Saint-Tropez next door might. Treating a region rather than a single field roughly multiplies what you can catch.
5. Stay flexible on the date. A leg that is wrong by a day is still a leg. The wider your window, the more repositioning flights fall inside it.
Why a route alert wins
Every other method asks you to be looking at the right moment. An alert removes that. You register the corridor once, then get on with your life; the system carries the burden of watching, and you only engage when a real, bookable leg on your route exists. On popular corridors the gap between a leg appearing and someone booking it is measured in minutes, so being told the moment it lists is often the difference between flying and missing.
It also compounds. Register a handful of corridors you fly regularly and you build a quiet, standing pipeline of opportunities — most of which you will pass on, until the one that fits lands in your inbox.
How flexibility multiplies your odds
Empty-leg supply is fixed — you cannot make a jet reposition on demand. What you can change is how much of that supply you are eligible for. Two levers do the heavy lifting: the date window and the airport radius. Flexing both turns a near-impossible exact match into a realistic one. If neither can move — a fixed meeting, a fixed return — an empty leg may simply not be the right tool, and a full charter buys you the certainty instead.
Mistakes that cost you legs
Three recur. The first is treating empty legs as a schedule — checking once, seeing nothing, and concluding there is no supply. There is; you were just looking outside the window. The second is paying for a "daily feed" of cheap legs: the genuine inventory is the same marketplace everyone draws from, so what you are usually buying is membership, not access. The third is hesitating. A good leg at a real discount will not wait while you think it over, which is the strongest argument for having the alert set and the broker briefed before you need them.
Common questions
How far in advance do empty legs appear?
Usually a few days to a few weeks before departure, though some surface the day before. They are tied to when the surrounding charters are confirmed, so there is no fixed schedule — which is why a route alert is the most reliable way to catch one.
Do I need an account to find empty legs?
No. You can search the live marketplace without registering. You only share details when you want a confirmed price on a specific leg.
Are empty legs cheaper if I find them myself?
The price is set by the operator, not by how you find the leg, so searching directly does not unlock a lower figure. What finding them well changes is whether you catch the right leg at all.
Can a broker find legs I cannot see?
Often, yes. Operators frequently offer repositioning to their broker contacts before it reaches any public list, so a broker can surface off-market legs — particularly useful when your dates are firm.
What is the single best way to find an empty leg?
A route alert on the corridor you want. It watches continuously and tells you the moment a bookable leg appears, which suits inventory that is unpredictable and sells fast.
How quickly do empty legs sell?
On popular routes, within hours of listing — sometimes minutes. The discount is genuine, so demand is real, which is why speed matters more than patience.
