Clearing Customs by Private Aircraft
At an airport where customs is present, which is a shorter list than the list of airports. Athens, Thessaloniki, Heraklion, Chania, Corfu and Rhodes have it all year. A further group — Mykonos, Santorini, Paros, Milos, Naxos, Skiathos, Kos and others — has it seasonally, broadly from the start of April to the end of October. A flight arriving from outside the customs territory has to make its first landing where customs is, which is why an August itinerary sometimes begins on a different island from the one in the brief.
The question is customs, not passports
Two different checks are involved in arriving in Greece, and confusing them produces most of the trouble.
Passport control applies to arrivals from outside the Schengen area. It establishes who is entering.
Customs applies to arrivals from outside the customs territory of the European Union. It establishes what is entering, including the aircraft itself.
For private aviation the second is the one that constrains the itinerary, because customs is not present at every Greek airport and is not present all year at several of the ones people want.
Where customs sits all year
Six airports carry customs through the year: Athens, Thessaloniki, Heraklion, Chania, Corfu and Rhodes.
Any of them can take a first landing from outside the Union at any date. In practice Athens does most of it, and the formalities there are completed inside the general aviation terminal rather than in the main building — the arrangement described in what an FBO is.
Where it sits only in season
A second group carries customs seasonally, broadly from 2 April to 31 October: Mykonos, Santorini, Paros, Milos, Naxos, Skiathos, Kos, Kalamata, Zakynthos, Kefalonia, Samos, Chios, Mytilene and Kavala, among others.
Inside those dates a flight from outside the Union can land directly on the island. Outside them it cannot, and the aircraft has to clear on the mainland or at one of the six first.
The dates are set administratively and they move. They are a question for the handler for the specific date, not a fact to be carried in the head from a previous summer.
The lounge you may not skip
At Mykonos, Corfu and Kos there is a small separate facility for general and business aviation, with security, customs and immigration in it. Use of it is mandatory for general and business aviation flights.
That matters for the choreography of an arrival rather than for its legality. A party expecting to step from the aircraft into a car will pass through a building first, and at Mykonos in August that building is busy with everybody else doing the same thing at the same hour. It is a short process and it is not optional.
What it does to an itinerary
Three consequences worth planning around.
The first landing is the constrained one. Once the aircraft and the party are inside the Union, movements between Greek airports are domestic and the customs question falls away.
The shoulder season changes the map. A flight arriving in March or November from outside the Union has six airports available, not twenty. An island arrival in that window generally means a mainland stop first.
Everybody clears, including the crew and the aircraft. Customs formalities attach to the flight, not to the passengers alone, and general declarations and crew documentation are part of what the handler files.
What to settle with the handler
- Where the first landing is, and whether customs is present there on your date.
- Whether the season applies to the island airport in the brief, and what the alternative is if it does not.
- What documents the crew must have filed, and by when.
- What is being carried. Firearms for a shoot, large sums of cash, a pet, high-value goods or artwork each have their own declaration, and each is a reason to arrive at a full customs airport by choice rather than by accident.
- How long the process takes at that specific airport in August — an honest handler answers in minutes, not adjectives.
