  - Busses and shuttles to and from the airport
Most companies use Terminal 1 (the older of the two). Terminal 2 is mainly used by Air France (and its partners) and Easyjet. To get to the city center or to go to the conference site, the best option is to take tram line 2 directly from the airport terminal towards 'Port Lympia' and change at the 'Jean Médecin' stop and then take line 1 towards 'Henri Sappia'. Then follow the instructions above to reach the conference venue. The round trip to the airport by tramway costs 10 Euros. Outside the airport, the tram ticket costs 1.7 Euros and can be purchased at the machines present at each stop. So you can have a stroll, exit the airport and reach the Tramway Line 2 stop 'Parc Phoenix' by a stroll of 15 minutes and by a ticket at that stop for 1.7 Euros.

A free shuttle connects Terminal 1 and 2 in both directions.
