Empty legs by season: when and where they appear

Why empty-leg supply follows a season at all

An empty leg only exists because a private jet has to fly somewhere with nobody aboard — typically returning from wherever it just dropped a client, or repositioning ahead of its next booking. That single fact is the whole explanation for why supply is seasonal: private jet travel itself follows recognisable patterns through the year, concentrated around ski season, the Mediterranean summer, and a calendar of major events, and empty legs simply mirror wherever that underlying demand is heaviest.

This matters practically because it means a route that shows nothing today might list several options in a few weeks, purely because the calendar moves into its peak window — and a route with legs everywhere in July might go quiet by October. Timing a search around the season, not just the destination, meaningfully improves your odds.

Ski season: December to March

Alpine routes carry the heaviest concentration of private jet traffic anywhere on the calendar, and the pattern within the season is fairly consistent year to year. Traffic builds through December, peaks hard around the Christmas and New Year fortnight and again over February half-term, and tapers into March as resorts wind down.

Geneva, the main gateway for the French and Swiss Alps, sees the heaviest and most reliable empty-leg volume of any ski corridor — high enough traffic that legs appear on both the outbound and return direction throughout the season. Courchevel, Verbier, Gstaad and St Moritz see real but more concentrated activity, clustering hard around the two peak fortnights rather than spreading evenly across the season.

The single best window across the whole ski calendar is the days immediately following New Year and immediately after February half-term — the exact points when the highest volume of aircraft are repositioning back out of the mountains at once.

Mediterranean summer: June to September

The Mediterranean coastal season runs longer and builds more gradually than ski season, but reaches an even higher peak at its height. Traffic picks up through June, peaks hard across July and August, and holds through September before dropping off sharply into autumn.

Nice and Cannes — the gateways to the French Riviera — carry the heaviest volume on this corridor, with Ibiza, Mykonos, St-Tropez and Olbia (for Sardinia's Costa Smeralda) close behind. August specifically is the single busiest month anywhere on the Mediterranean network, which cuts both ways: the most aircraft movements of the year, but also the most competition for any given leg once it lists.

Event-driven spikes, outside the two main seasons

Beyond the two broad seasons, specific events reliably concentrate private jet traffic into a short window regardless of time of year — the days around Monaco Grand Prix, Wimbledon, the major art fairs and similar fixtures each create a localised spike in both directions on their nearest gateway airport. These spikes are real and worth watching, but they're narrower and less predictable than the two seasonal windows above, since a single event's dates shift the exact peak by a few days each year.

The practical approach: treat the event calendar as a layer on top of the two main seasons, not a replacement for them. A route that's already busy for seasonal reasons gets busier still around a major event on that corridor; a route with no seasonal traffic won't suddenly generate empty legs just because an event is happening nearby, unless that event itself draws private jet traffic in volume.

The quiet months, and what they mean for you

Every destination has an off-season, and it's worth being honest about what that means for empty-leg search: fewer aircraft moving on that route translates directly into fewer legs listing, full stop. Ski corridors go quiet from April through November; Mediterranean routes go quiet from October through May. There's no trick to finding volume where the underlying traffic simply isn't there.

What this means practically is that timing flexibility often matters more than route flexibility. If your dates can shift into a route's actual season, you'll see meaningfully more options than staying rigid on a date that falls in that route's quiet period, even if you're completely flexible on which destination you're willing to consider.

A worked example: timing a Geneva search

Take a concrete case: searching London to Geneva for a ski trip. Search in September and the corridor is essentially quiet — a handful of legs at best, since ski season hasn't started and the previous winter's traffic ended months ago. Search in mid-December, as the season is building, and volume starts climbing steadily. Search in the first week of January, right after the Christmas and New Year fortnight, and this is typically the strongest window of the entire season — the highest concentration of aircraft repositioning back out of the Alps in a short space of time.

Push the same search into March and volume is already tapering as the season winds down; by April it's back to near-silence until the following winter. Same route, same aircraft class, four wildly different outcomes depending purely on which week you search — which is the entire argument for treating the calendar as seriously as the destination when planning a flexible trip.

How to actually use this when searching

• Match your search window to the season, not just the route. Searching a ski corridor in August, or a Mediterranean route in January, will show far less than searching either in its actual peak window.
• Target the days just after a peak period ends. The post-New Year and post-February-half-term windows on ski routes, and the September tail on Mediterranean routes, are consistently strong for repositioning supply.
• Set a route alert rather than checking once. Given how concentrated supply is around these windows, a single check outside the peak will understate what's genuinely available once the season turns.

Common questions

What time of year has the most empty legs?

There isn't one single answer — it depends on the route. Ski corridors peak from December to March; Mediterranean coastal routes peak from June to September, with August the single busiest month across the whole network.

When is the best time to find a ski-route empty leg?

The days immediately following New Year and immediately after February half-term, when the highest concentration of aircraft are repositioning back out of the Alps at once.

Do empty legs to the Mediterranean slow down in autumn?

Yes, sharply. Traffic holds through September and then drops off quickly into October as the summer season ends, mirroring the underlying drop in private jet travel to the region.

Are event weekends good times to find empty legs?

They can be, on the specific gateway airport nearest the event, but the effect is narrower and less predictable than the two main seasons — worth watching as an addition to seasonal timing, not a substitute for it.

Which ski destination has the most reliable empty-leg supply?

Geneva, as the main gateway to the French and Swiss Alps, sees the heaviest and steadiest volume of any ski corridor throughout the season, on both outbound and return legs.

Is August a good time to search for a Mediterranean empty leg?

It's the busiest month for volume, but also the most competitive — the most aircraft are moving, but also the most demand chasing each one. Late August into September, as the season tails off, can offer a better balance.

What happens to empty-leg supply outside the main seasons?

It drops significantly on seasonal routes, because there simply isn't the same underlying private jet traffic generating repositioning flights. This is a genuine limitation, not a search technique to work around.

Should I be flexible on route or on dates?

If you're choosing one, date flexibility that lets you search within a route's actual season usually outperforms being completely open on destination but rigid on timing.

Do these seasonal patterns apply to every destination?

The broad ski-winter and Mediterranean-summer pattern applies to the corridors this site covers most heavily. Destinations outside Europe, or served for business rather than leisure travel, follow different patterns tied to their own demand drivers.

How far ahead should I set a route alert for a seasonal peak?

Setting an alert a few weeks before a route's season begins is a reasonable approach, since it captures the building traffic rather than only the peak days themselves — empty legs still surface only a few days to a few weeks before departure even within a strong season.
