Changes to slot and parking rules at Athens International Airport (LGAV) are set to impact business aircraft operators starting March 30. Flight support group Universal Weather and Aviation has warned operators to prepare their schedules around the new Greek requirements to avoid disruption through the summer months.

The airport is moving to level-two slot coordination that will result in “deviations” in requested arrival and departure times for last-minute slots, especially at peak morning and mid-afternoon times. Universal has advised that delays of an hour or more should be expected if slots and prior permission approvals are not secured in advance.

Operators have also been told that free parking at LGAV will be reduced to two hours, compared with between eight and 12 hours currently Any stay longer than two hours will be subject to confirmation by the airport operator and will be granted only 24 hours before the planned arrival.

The revised rules will apply to all aircraft with an mtow of more than 5,700 kilograms (12,566 pounds), whether they are private or charter flights, including ferry and technical stops. Exemptions are available for ambulance flights, as well as for military and parapublic operations.

If an operator needs to extend their stay in Athens, they will have to file a new prior permission request. Universal said approvals are unlikely due to ramp space limits.
