Empty leg vs full charter: which is right for your trip

The difference in one line

Strip away the marketing and the choice is simple. An empty leg and a full charter put you on the same class of aircraft, with the same crew, the same private terminal and the same safety standards. The single structural difference is control: a charter is built around you — your route, your date, your return — while an empty leg is built around the aircraft's repositioning needs and sold cheaply because the flight is happening anyway. Everything else, the price, the flexibility, the certainty, flows from that one fact.

So this is not a question of quality versus economy. Nobody flies a worse aircraft on an empty leg. It is a question of who is in charge of the schedule. Pay the full charter price and the answer is you; take the discount of an empty leg and the answer is the operator. Which of those is worth more depends entirely on the trip in front of you, and the rest of this guide is about telling the two cases apart.

It is worth dispelling one myth before going further: that the discount must come from somewhere, that an empty leg is in some way a lesser flight. It is not. Operators do not keep a shabbier fleet for repositioning, nor a junior crew; the aircraft flying empty to its next job is frequently the very one that flew a full-fare charter that morning. What you are buying is unsold capacity on a premium asset, which is why the saving carries no hidden compromise on the flight itself — only on the freedom to choose where and when it goes.

What an empty leg gives you, and what it costs you

What it gives you is the headline: the same private jet for 25–75% less than chartering it outright. A repositioning flight the operator was going to fly empty becomes your flight, at a fraction of retail, with nothing about the cabin, the crew or the service downgraded. For the right trip it is the best value in private aviation, and it is covered end to end in our guide to Empty legs, explained.

What it costs you is control. You take the route the aircraft is already flying and the date it is already flying it; you do not pick either. An empty leg is also one-way by nature — it exists to move the aircraft in a single direction — and it is perishable, surfacing days to weeks ahead and vanishing the moment someone books. Because the leg depends on the charter it follows, a change to that underlying booking can occasionally move or cancel it. None of that troubles a flexible traveller; all of it matters if your plans cannot bend.

What a full charter gives you

A full charter is the opposite trade. You name the route, the date, the departure time and the aircraft; the operator builds the flight around your requirements and contracts to deliver it. You can fly out and back on the days you choose, from the airports you choose, on a schedule that is yours rather than the aircraft's. If the trip has to happen at a fixed time and a fixed place, a charter is the only one of the two that guarantees it.

That certainty is the product, and it is what you pay the full hourly rate for — the same rates set out in our breakdown of what What private jets cost really costs. A charter does not save you money against retail because it is retail; what it buys is the removal of every variable an empty leg leaves open. For a board meeting, a wedding, a connection you cannot miss, that removal is often worth far more than the discount you would have saved.

A charter also lets you tune details an empty leg never exposes: the exact departure time, the specific airports at each end, even the aircraft type if you have a preference. For a traveller who values an early slot, a particular runway close to a venue, or a cabin sized precisely to the party, that control is part of what the premium buys — and none of it is on the table when you take whatever happens to be repositioning.

The cost gap, with real numbers

Charter is priced by the hour, by aircraft class, and an empty leg discounts heavily off that figure:

Put a route to it. To charter a midsize jet from London to Nice one way runs roughly £14,000–£22,000. The same aircraft as an empty leg, when one is repositioning that way, might be £4,500–£11,000 — and a full charter return roughly doubles the charter figure, while an empty leg never offers a guaranteed return at all. The gap is the whole story: you are trading a large, certain saving against a set of conditions you have to be able to accept.

The discount is not a fixed percentage, either. How deep it runs depends on the route, the aircraft and, above all, how close to departure the leg is still unsold — a leg empty the day before it flies is marked down hardest, because at that point any recovery beats none. A charter price, by contrast, is stable and quotable well in advance. So part of the trade is predictability: the charter tells you the number now, while the empty leg offers a better number you have to be in position to catch.

For a group the empty leg's advantage widens, because the price is for the whole aircraft. Eight people splitting an £8,000 leg pay £1,000 each; the same eight splitting a £20,000 charter pay £2,500. The charter still buys them a guaranteed date and a guaranteed return — but if they can flex, the empty leg's per-head figure is hard to argue with. The full pricing picture, for both, is in our guide to what empty leg flights cost.

One number that surprises people is how little the aircraft itself differs in running cost between the two. A charter and an empty leg on the same jet burn the same fuel and carry the same crew; the entire price gap is commercial, not operational. That is reassuring in a way — the cheaper option is not cheaper because anything has been cut, only because the operator would rather sell a flight twice than fly it once empty.

Control, certainty and the return problem

The honest crux of the comparison is the return. A charter is a round trip by default: you fly out on Friday, the aircraft waits or repositions, and it brings you back on Sunday, all contracted in advance. An empty leg is one direction only. A round trip built entirely from empty legs needs two separate repositioning flights to line up with your dates and airports, which is rare enough that most travellers don't rely on it.

Certainty runs the same way. A charter is fixed the moment it is contracted — the operator owes you that flight. An empty leg is contingent: it exists because of a paying charter elsewhere, and if that booking changes, your leg can move with it. It is uncommon, but it is real, and it is why an empty leg suits a trip that can absorb a change and a charter suits one that can't. If your dates can flex but you still want to weigh it carefully, our honest look at whether empty legs are worth it walks through the trade case by case.

When the empty leg wins

The empty leg wins whenever flexibility is on your side. If your dates can move a day either way, if you are travelling as a group who can split a whole-cabin price, and if you are on a busy corridor where repositioning flights are frequent — London to Nice, London to Geneva, the hops between the Mediterranean and the Alps — the discount is real and the conditions are easy to meet. A group heading to Ibiza or Mykonos for a summer weekend, happy to take Friday or Saturday and a nearby airport, is the textbook case: they catch a leg, split it, and fly private for a figure that competes with premium commercial fares.

It also wins for the genuinely one-way trip — a relocation, a one-direction leg of a longer journey, a positioning flight you'd have paid for anyway. When you only need to get there, the empty leg's single biggest limitation simply doesn't apply, and the saving is pure upside.

The common thread in every empty-leg win is the same: the route generates enough repositioning traffic that a match is likely, and your plans are loose enough to take one when it appears. Get both right — a busy corridor and a flexible diary — and the empty leg is not a gamble, it is simply the cheaper way to do exactly the trip you were going to take.

When the charter wins

The charter wins whenever the trip cannot move. A wedding, a board meeting, a Grand Prix you have tickets to, a medical appointment, a connection onto a cruise or another flight — anything with a fixed date, a fixed place and a return you have to make is a charter trip, full stop. Paying the premium buys the one thing an empty leg cannot promise: that you will be where you need to be, when you need to be there, in both directions.

There is a quieter reason charters win, too: the cost of the trip failing. If missing the flight means missing the deal, the wedding or the once-in-a-lifetime event, then the few thousand pounds saved on an empty leg is a false economy the moment the leg moves. Pricing in the consequences of a disruption, not just the headline fare, is what separates a confident charter booking from a regretted empty-leg one.

It also wins on thin routes and for solo travellers. If you are flying somewhere off the busy corridors, or flying alone with no group to share the cost, empty-leg supply is sparse and the per-head maths is weak — so the wait rarely pays off and a charter is the more sensible buy. The rule of thumb: the more your trip looks like a fixed commitment, the more a charter's certainty is worth paying for.

The hybrid most people miss

The two are not mutually exclusive, and the smartest bookings often combine them. If only one direction of your trip can flex, take an empty leg for that leg and a charter — or even a scheduled first-class seat — for the one that can't. You capture the discount where flexibility allows it and buy certainty only where you actually need it, instead of paying the full premium on both halves.

In practice this is how a lot of seasoned private flyers travel. They set a route alert for the flexible direction, let an empty leg come to them, and lock a charter or a commercial seat for the fixed direction in advance. It takes a little more organising than a single round-trip charter, but on the right trip it is the cheapest way to fly private without giving up the certainty that matters.

How to decide in a minute

One question settles most of it: can your dates and your airports move? If yes, start with an empty leg — set an alert, stay ready, and take the discount when a match appears. If no, book a charter and pay for the certainty; it is what the premium is for. If only one direction can move, run the hybrid and get the best of both.

Two follow-ups sharpen it. How many of you are travelling — because a group makes the empty leg's whole-cabin economics shine, while a solo traveller leans towards a charter on all but the busiest routes. And how critical is the return — because a must-make return is the single clearest signal that this is a charter trip. Answer those three honestly and the right choice is usually obvious before you have looked at a single price.

And if it is not obvious — if the trip sits genuinely between the two — default to the hybrid. Taking the discount on the half that can flex and buying certainty on the half that cannot is rarely the wrong answer, and it is almost always cheaper than chartering both directions out of caution.

Common questions

What's the difference between an empty leg and a charter?

The aircraft, crew, terminal and safety standards are the same. The difference is control: a charter flies your route on your date, built around you; an empty leg flies the operator's repositioning route on their date, sold at 25–75% less because the flight was happening anyway.

Is an empty leg the same aircraft as a charter?

Yes. An empty leg is simply a charter aircraft repositioning without passengers. You get the same jet, the same crew and the same private-terminal experience — the discount is on the routing, not the standard of the flight.

Is a charter safer than an empty leg?

No — both use the same operators and aircraft, held to the same ARGUS and Wyvern safety standards. Safety is identical; the only practical differences are price, routing and certainty.

How much cheaper is an empty leg than a charter?

Typically 25–75% below the equivalent one-way charter. The exact figure depends on the route, the aircraft and how close to departure the leg is posted, but the saving is genuine because the operator is recovering the cost of a flight they would otherwise fly empty.

Can I get a return flight on an empty leg?

Not as a guarantee. An empty leg is one-way by nature. A round trip on empty legs needs two separate repositioning flights to align with your dates, which is rare — so most people pair an empty leg out with a charter or a scheduled seat back.

Can I choose the date on an empty leg?

No — the date and route are set by where the jet needs to reposition. If you need a specific date and route in both directions, that is a charter. The more flexible you can be, the more empty legs you will be able to match.

When is a full charter worth the extra cost?

Whenever the trip cannot move — a fixed date, fixed airports and a must-make return — and whenever you are flying solo or on a thin route where empty-leg supply is scarce. In those cases the certainty a charter contracts to deliver is worth more than the discount.

Can I combine an empty leg and a charter?

Yes, and it is often the smartest option. Take an empty leg for the direction that can flex and a charter for the direction that can't. You get the discount where flexibility allows and certainty where you need it, rather than paying full price both ways.

Which is better for a group?

For a flexible group, the empty leg is usually the clear winner: the whole-cabin price split across everyone travelling drives the cost per head down sharply. A charter still wins for a group on a fixed-date trip with a return they have to make.

Can an empty leg be cancelled when a charter can't?

Yes. A charter is contracted and fixed; an empty leg is contingent on the paying charter it follows, so a change to that booking can occasionally move or cancel your leg. It is uncommon, but it is the reason to keep a fallback for anything time-critical.
