Volos airport (VOL) is situated in (Nea Anchialos), about 30 km SW from the city, and currently operates only weekly charter flights during the summer, directly from Amsterdam and the UK. There are expansion projects of the airport underway, as well as a rail connection from Volos city to the airport, so as to be able to start some commercial routes as well.
By regional coach
Interurban coaches ("KTEL" buses) are by far the most convenient way to travel around Greece, as well as for intra-regional travelling. There is frequent bus service from Athens Liossion Station to Larisa about 15 times a day (cost is about €20), as well as from Thessaloniki bus terminal "Macedonia" to Larisa about 10 times a day (about € 12).
Trains (OSE) connect Larissa to other cities in Greece. Travelling with ordinary trains can be cheaper, although a little bit slower, whereas choosing a fancy faster Intercity train will cost the same amount of money, or even more than a KTEL bus.
