There are three parking areas at Athens International Airport. Parking areas P1 and P2, which are recommended for short term parking (less than 5 hours), are located very near to the arrivals level. Parking is FREE at P1 and P2 for the first 20 minutes. Parking area P3 is a bit further and it is used for long term parking. You can easily enter the parking areas by following the signs at Attiki Odos. The parking fees are shown in the Pricelist.
Friday to Sunday: You can park in the Long Term parking (P3) from Friday 00:01 am to Sunday 11:59 p.m. for just 25 euros. Have in mind however, that the use of this service beyond the specified time frame cancels the offer and the total charge is made according to the normal price list.
