What an FBO Is

An FBO (fixed base operator) is the company that receives a private aircraft at an airport, and the terminal where it receives it. It parks and fuels the aircraft, files what the authorities require, and takes passengers between the car and the aircraft steps through a building with its own security, passport control and customs. Athens has a dedicated general aviation terminal that works around the clock. The summer island airports are a different problem. There, service is not scarce. A slot and a parking stand are.

What an FBO does

An FBO, or fixed base operator, is two things at once: a building and a company.

The building is a small terminal for private flights, separate from the commercial terminal. The company runs it and handles the aircraft. It guides the aircraft in and parks it, fuels it, orders catering, arranges the cleaning and files what the airport and the authorities require. It also moves passengers and bags between a car on one side and the aircraft steps on the other.

Everything else people associate with private flying comes from this arrangement, not from the aircraft. The short walk, the lack of a queue and the car on the apron, where the rules allow it, all come from the terminal and not from the jet. The apron is the area where aircraft park.

What changes inside the terminal

General aviation is the term for flying outside the scheduled airlines. A general aviation terminal has its own security screening, its own passport control and its own customs. That is its purpose. A passenger goes through the same checks as everyone else, but in a room with four other people instead of four hundred.

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

Two things stay the same. The first is the checks themselves. A flight arriving from outside the Schengen area, the group of European countries without passport checks at their shared borders, is checked as a non-Schengen arrival wherever it parks. The second is that the aircraft still needs a slot, an approved time to land or take off, and a parking stand like every other aircraft on the airfield.

FBO, handler, operator, broker

Four companies commonly deal with one private flight. Confusing them is how a passenger ends up complaining to the wrong one.

What it isWhat it answers for
FBOThe private terminal and its operatorThe ground: parking, fuel, formalities, the passenger experience on the airfield
Ground handlerThe company working the aircraftLoading, guiding the aircraft on the ground, ramp services. Sometimes the FBO, sometimes not
Aircraft operatorThe company that holds the operating certificate and employs the crewThe flight itself: airworthiness, crew, the decision to go
Charter brokerThe intermediary that sources the aircraftFinding and contracting the flight, not performing it

The third column is the one that matters. When a departure is delayed, the cause lies with the operator or with the airfield. The FBO is the party best placed to say which, but it is not the party that caused the delay.

What Greece requires before the aircraft moves

Greece controls who may fly commercially into its airports, and it applies that control before departure, not on arrival.

A non-EU-registered aircraft operating a non-scheduled commercial flight into Greece needs a permit from the Hellenic Civil Aviation Authority. The published minimum lead time is 5 working days, and the authority’s own workload makes it longer in summer. The documents required are the operating licence, the certificate of airworthiness, the registration certificate and the approved security programme.

An EU-registered aircraft flying within the EU does not need that permit. This is one reason the fleet flying around the Aegean in August looks the way it does.

Why the islands are the constraint

In Greece the problem is rarely service. It is space.

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. This means every movement, private or commercial, needs an approved slot before departure. It has one runway, 2,197 metres long, working at capacity from late May to September. In the first weeks of August the apron runs out of room, and requests filed within 4 weeks of the date are frequently refused outright.

This shapes the whole day. Aircraft land, set down their passengers and reposition to Athens or another mainland airfield, then return for the pickup. That is normal and planned for. A schedule that assumes the aircraft waits on the island will not be approved.

What to settle before a summer flight

  1. The slot comes first. On Mykonos and Santorini in July and August the slot sets the timing, and the timing then sets the day.
  2. Ask where the aircraft parks between legs, and what the repositioning does to the return.
  3. Ask which permits the operator needs and when they were applied for, not whether they are “in hand”.
  4. Ask where you clear customs and immigration, especially on a first arrival from outside the Schengen area.
  5. Ask what happens if the slot moves. A straight answer names an alternative airfield instead of offering reassurance.
