Best way to reach Athens Airport from Volos or Agios Konstantinos

The Question:

Best way to reach Athens Air port from Volos or from Ag. Konstantinos by bus or by train.
Thank you

The Answer:

Hello there!
I would suggest the train because as soon as you arrive in Athens you will be able to easily change to the Suburban railway which will take you straight to the Athens International Airport. From the bus station of Liosion in Athens you will have to change at least 2 different means of transport to finally reach the airport.
