Empty Leg Flights in Ski Season: How Positioning Works, December to March

An empty leg is a flight an aircraft has to make anyway, with nobody on board. Ski season produces more of them than any other time of year on European routes, because the traffic is overwhelmingly one-directional at weekends. Savings of 50 to 75% against a full charter are normal. The catch is that you take the aircraft, the airport and the date the operator is already committed to.

Why ski season creates so many empty legs

Alpine charter traffic is lopsided in a way almost no other season is. On Friday and Saturday, aircraft fly full into Geneva, Sion, Chambery and Salzburg, and fly out empty. On Sunday the pattern reverses exactly. An operator with an aircraft committed to a Saturday afternoon drop-off in Geneva has a machine and a crew sitting there with a return leg to fill, and every hour it sits, it costs them.

That is the entire mechanism. You are not being offered a discount out of generosity; you are being offered the chance to cover a cost the operator has already incurred. It is why the savings are real, and why the terms are inflexible.

What you can realistically expect to save

Between 50% and 75% of the full charter price, with the deepest discounts on the legs nobody wants: early morning, midweek, or an airport that is forty minutes further from the resort than the obvious one. On the London to Geneva corridor, a full charter starts around 8,900 euros; empty legs on the same sector have been listed from 2,800 euros.

The four constraints, stated plainly

The date is fixed. Not flexible within a day. Fixed. If the operator moves the original booking, your leg moves or disappears with it.

The aircraft is fixed. You get what is flying. If it is a light jet and you have six people and ski bags, that is a problem to solve before you book, not after.

The airports are fixed at both ends. An empty leg into Sion instead of Geneva may cost you an hour of road transfer at the far end.

It can cancel. If the original charter cancels, the positioning flight it created no longer exists. Reputable brokers tell you this before you pay. We do.

How to actually get one

The single biggest mistake is watching a public empty-leg list. By the time a leg is published, it has usually been offered to a private list first. The way to be early is to register your route and your date range in advance, so you are contacted when a match appears rather than refreshing a page.

Decide your route and the widest date window you can genuinely accept. Register interest on that corridor. Be ready to confirm within hours, not days, because these do not sit. And have a fallback: if nothing appears by a set date, book the full charter rather than losing the trip.

The routes that produce the most

London to Geneva is the heaviest Alpine corridor in Europe and empties both ways at weekends, with the best availability Sunday to Wednesday. Northern Europe into Sion and Chambery is thinner but more deeply discounted, and is a midweek game. Gulf to Geneva and Zurich produces long-range aircraft repositioning after winter drop-offs, concentrated in January and February. And the Geneva to London Sunday return wave means the outbound Saturday sector is frequently empty. If you are heading to the French Alps specifically, our Courchevel and French Alps guide covers the arrival airports and transfer times in detail.

Frequently asked questions

Are empty legs cheaper than commercial business class?

On a full aircraft, often yes. Split four or six ways, a 2,800 euro empty leg from London to Geneva is competitive with flexible business-class fares, before you count the time saved on the ground.

Can I change the date or the time?

No. The leg exists because the operator has already committed the aircraft. Any flexibility on your side helps you find one; none of it applies once you have.

What happens if the original charter cancels?

Your leg goes with it, and you are refunded. This is the real risk of empty legs and the reason we always ask whether you have a fallback before you commit.

How far ahead do empty legs appear?

Usually one to fourteen days. Longer than that and the original booking is rarely firm enough for the operator to release the positioning leg.
