What an FBO Is

What an FBO actually does

Strip the term back and an FBO is two things at once: a building and a company.

The building is a small terminal for private flights, away from the commercial one. The company runs it and handles the aircraft — marshalling and parking it, fuelling it, ordering catering, arranging the cleaning, filing what the airport and the authorities want filed, and getting passengers and bags between a car on one side and the aircraft steps on the other.

Everything else people associate with private flying follows from that arrangement rather than from the aircraft. The short walk, the absence of a queue, the car on the apron where the rules permit it: those are functions of the terminal, not of the jet.

What changes inside the terminal

A general aviation terminal has its own security screening, its own passport control and its own customs. That is the whole point of it — a passenger clears the same formalities as everybody else, in a room with four other people rather than four hundred.

Athens International Airport runs a dedicated general aviation terminal, separate from the main building and staffed around the clock. It is the country’s principal private-flight facility and the one most international arrivals use.

Two things do not change. The formalities themselves are unchanged: a flight arriving from outside the Schengen area is checked as a Schengen arrival wherever it parks. And the aircraft still needs a slot and a stand like everything else on the airfield.

FBO, handler, operator, broker

Four companies commonly touch one private flight, and confusing them is how a passenger ends up complaining to the wrong party.

	What it is	What it answers for
FBO	The private terminal and its operator	The ground: parking, fuel, formalities, the passenger experience on the airfield
Ground handler	The company working the aircraft	Loading, marshalling, ramp services — sometimes the same firm as the FBO, sometimes not
Aircraft operator	The company that holds the operating certificate and employs the crew	The flight itself: airworthiness, crew, the decision to go
Charter broker	The intermediary that sources the aircraft	Finding and contracting the flight, not performing it

The column that matters is the third one. When a departure slips, the answer sits with the operator or with the airfield, and the FBO is the party best placed to tell you which — not the party that caused it.

What Greece requires before the aircraft moves

Greece controls who may fly commercially into its airports, and the control is applied before departure rather than on arrival.

A non-EU-registered aircraft operating a non-scheduled commercial flight into Greece requires a permit from the Hellenic Civil Aviation Authority. The published minimum lead time is 5 working days, and the authority’s own workload lengthens in summer. Documentation runs to the operating licence, the certificate of airworthiness, the registration certificate and the approved security programme.

An EU-registered aircraft flying within the Union does not face that permit, which is one reason the fleet operating around the Aegean in August looks the way it does.

Why the islands are the constraint

Service is rarely the problem in Greece. Space is.

Mykonos operates under slot coordination through the season, with tight limits on how long an aircraft may stay on the ground.

Santorini is a level 3 coordinated airport at peak, meaning every movement — private or commercial — needs an approved slot before departure. It has one runway, 2,197 metres, working at capacity from late May to September. In the first weeks of August the apron simply runs out of room, and requests filed inside 4 weeks are frequently refused outright.

The practical consequence shapes the whole day. Aircraft land, set down their passengers and reposition to Athens or another mainland field, then return for the pickup. That is normal, it is planned for, and a schedule built on the assumption that the aircraft waits on the island is a schedule that will not be approved.

What to settle before a summer flight

1. The slot, before anything else. On Mykonos and Santorini in July and August the slot decides the timing, and the timing then decides the day.
2. Where the aircraft parks between legs, and what the repositioning does to the return.
3. Which permits the operator needs, and when they were applied for — not whether they are “in hand”.
4. Where you clear customs and immigration, particularly on a first arrival from outside the Schengen area.
5. What happens if the slot moves. The honest answer involves a named alternative airfield, not a reassurance.
