Although it was projected that only commuter rail would use the station, the Athens Metro operating company decided to extend Line 3 to the airport.
Because of the limited availability of these trains (7 in total), only 1 or 2 per hour reach the station, leaving the airport every 36 minutes from 06:10 to 23:34.
Moreover, for many years there have been plans to extend Suburban Railway services to Rafina, a suburb of Athens and the third largest harbour of the city as well.
Although original plans show the line branching off the main one after Pallini or Doukissis Plakentias Station, then running in a reserved-for-this-purpose median of the A64 Mount Hymmetus Ring Road and then extending to Rafina, recent plans have called for an extension of the line from the Airport.
Such an extension would be shorter and less expensive to build, however, it has been unpopular due to the fact that the travelling time from and to Rafina will be longer and certain areas will not be served.
