Turin's international airport is located 15km north of the city center and is named after Italy's former President Sandro Pertini. It is in the town of Caselle, connected to Turin city by a convenient motorway.
The main carriers to reach Torino from abroad are Lufthansa, Air France, Turkish Airlines and Alitalia if flying from Rome or Naples, Italy's flagship airline, which operates flight from some European and Italian cities. Caselle is also a destination for some low fares airlines, for example Ryanair and Easyjet. The airport is connected to the city by train (to the station of Porta Dora, which is useless. Arriving at the Porta Dora really is like arriving in the middle of nowhere.), bus (with a regional bus service, which is long) and taxi (30 euro one way to city centre at December 2010).
The SADEM bus service runs every 30-40 minutes from the airport to Torino's Porta Nuova train station. If you buy a ticket at a ticket kiosk inside the airport terminal, it will cost 6.50 euros. If you buy it on the bus, it's 7 euros. If you bought the Turin + Piemonte Card, the ride is only 5 euros. The voyage from the airport to the center of the city takes approximately 40 minutes.
Turin is also reached from Malpensa airport, which may be cheaper to fly to.
Turin has three main railway stations, Porta Nuova, Porta Susa and Lingotto FS.
Generally speaking, Porta Nuova and Porta Susa are stations dedicated to mid-range and long-range trains. The brand new stunning Porta Susa station serves trains to all northern regions of Italy, while Porta Nuova serves especially trains to the south. You'd better check in advance where you need to go. Many trains also stops in both stations. All trains coming from/going to the south of Turin, depart from Porta Nuova via Lingotto FS.
