  - 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 get off at the 'Jean Médecin' stop and then take line 1 towards 'Las Planas' and then follow the instructions above to reach the conference venue. The tram ticket costs 1.5 Euros and can be purchased at the machines present at each stop.
Alternatively, you can take bus n. 12 (ticket costs 1.5 Euro and can be purchased directly on the bus) but it takes 40 minutes to get to the NICE-Thiers station and then you have to walk 10/15 minutes to reach the tram. Airport buses depart from Terminal 1.

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