Cross-border corridors: the country pairs that dominate Europe's empty-leg map

Reading the map at the country level

The empty-leg feed is usually consumed as a stream of individual routes — Farnborough to Cannes, Munich to Palma, Nice to Ibiza. That is the correct unit for a broker filling a specific mission, but it obscures the larger structure of the market. When we roll up the same data to the country-pair level, matching each leg's departure and arrival ISO codes, roughly 80 percent of the traffic falls into a shortlist of pairs and the remaining 20 percent scatters across the long tail. The concentration is not quite as sharp as the operator distribution, but it is close, and it is stable month to month.

The US-to-US pool is the largest single bucket by an enormous margin. Roughly 65 percent of the entire global feed is a domestic US movement, dominated by the Van Nuys corridor to the Northeast, the Florida-to-Aspen ski axis, and the Texas-to-California business traffic. Anyone reading the feed for European supply first needs to strip the US pool out, at which point the shape of the European market becomes much clearer.

The five European pairs that matter

Once the US traffic is filtered, five directed country pairs account for well over half of what remains. The largest is Germany-to-Switzerland and its reverse: Munich to Zurich, Düsseldorf to Geneva, Berlin to Samedan, plus the Swiss-outbound flows to Sylt and the North Sea in summer. This is the classic DACH corridor, driven by financial services, family offices and the seasonal Alpine calendar; it produces the most stable empty-leg supply of any European pair and the discounts on it tend to be modest — 25 to 35 percent — because the aircraft usually reposition into another chargeable leg within hours.

France-to-Italy is the second largest. Nice, Cannes and Le Bourget on one side; Milan, Olbia, Rome and Naples on the other. The seasonality is intense — a Mediterranean summer spike from late May through early September — and the aircraft class mix is dominated by super-mids and light jets making short hops between principals' villas and business bases. Discounts on this pair reach the 50-percent range in the shoulder months and compress toward 20 percent in peak season, when the operators know every leg will be resold to someone.

UK-to-Spain is the third and, for the retail charter market, the most interesting. Farnborough, Luton and Biggin Hill on the London side; Palma, Ibiza, Malaga and Marbella on the Spanish side. The corridor is heavily leisure-driven and the demand is more elastic than the DACH or France-Italy flows, which means discounts run deeper — 40 to 60 percent is common in June and July on Friday evening and Sunday morning legs. This is the pair we recommend most often to first-time empty-leg buyers because the fit-for-purpose supply is genuinely large and the pricing behaviour is predictable.

The two pairs that carry the long weekend

Below the top three, two more pairs deserve a specific mention. Germany-to-Spain — mostly Munich and Düsseldorf to Palma and Ibiza — carries the German long-weekend traffic and produces a very predictable seasonal wave. The corridor overlaps with UK-to-Spain on the arrival side, which means Palma in particular becomes a natural repositioning bottleneck in July, with operators frequently offering deep discounts on the Palma-outbound leg because too many aircraft have arrived on the Friday evening and need to be repositioned before Monday morning.

Switzerland-to-France is the fifth pair and the smallest of the five, but it carries the highest average aircraft class of any European corridor. Geneva, Samedan and Zurich on one side; Le Bourget, Cannes and Chambéry on the other. Because the passengers on this corridor skew toward the highest end of the wealth spectrum, the aircraft mix runs toward Global 6000s, Falcon 8Xs and G550s — and the discounts on the resulting empty legs are the most attractive of any European pair in absolute-dollar terms, because a 30-percent discount on a heavy jet is a much bigger absolute saving than a 60-percent discount on a light jet.

The pairs that don't appear (and why)

What is missing from the top of the country-pair table is nearly as informative as what is on it. Germany-to-Italy, despite the obvious geographic and economic logic of the pair, sits well below UK-to-Spain in our data. The reason is that a large share of the German traffic to Italy routes through Switzerland or Austria for fuel, catering and operational reasons, and the leg ends up counted as DE-CH-IT rather than DE-IT. France-to-UK is similarly under-represented for a different reason: most Paris-London traffic is either short-hop commercial or rail, and the private-jet flow on that pair is small, tightly scheduled by the same handful of operators, and rarely produces empty legs of any commercial interest.

The Nordic pairs — Norway-to-Denmark, Sweden-to-Finland — appear only sporadically and almost always in the summer, driven by the archipelago and lakeside villa markets. The Eastern European pairs are similarly sparse, with the Czech Republic and Austria providing the only meaningful supply and Warsaw appearing occasionally on the operator side rather than the destination side. The Turkish pairs — Istanbul to Bodrum, Antalya to the Aegean — belong to a distinct regional market that overlaps with European supply only on the shoulder-season transfer legs.

Using the corridor map

For a buyer with route flexibility, the practical implication of the corridor concentration is that the best economics almost always live inside the five main pairs. Trying to force a mission onto a corridor with thin supply — Berlin to Milan, Manchester to Athens, Vienna to Marseille — will almost always cost more than picking up a mainline leg into a nearby hub and connecting on the ground. Palma is a better arrival airport than Malaga for most Costa del Sol destinations from a pricing standpoint because the leg supply is genuinely deeper; Geneva is a better arrival airport than Chambéry for most Northern Alps destinations for the same reason.

For an operator planning fleet deployment, the corridor map is a slow-moving strategic signal. A fleet operator with a base outside the top-five pairs will structurally see fewer empty-leg opportunities and lower repositioning revenue than one based on the DACH or Nice-Milan axis; the difference over a full year can amount to hundreds of thousands of euros in incremental yield per airframe. This is why the newer European operators cluster their bases in the same handful of cities — Geneva, Nice, Munich, Farnborough, Palma — rather than diversifying across the continent.

Reading the empty-leg feed at the country-pair level, in short, reveals a European market that is far less fragmented than it looks on a leg-by-leg basis. Five pairs carry the traffic, the seasonality of each pair is predictable, and the aircraft-class signature of each pair is stable enough to model. Any charter strategy that starts with a specific route and works outward will find fewer good outcomes than one that starts with the corridor map and asks which mainline leg most nearly fits the trip.
