There are two international airports for Paris: Roissy Charles de Gaulle (CDG) and Orly (ORY). You find a lot of information on both airports at the internet. See for example:
Most of the international participants will land at CDG.
There will be no pick-up for participants at the airports. However, you should not worry. France has a very good public transport. If you land at CDG, the easiest way to go to Paris is by Roissybus that will take you to Paris Roissybus station behind Opera House. Roissybus operates everyday from 05h00 to 00h30 with an interval of 15-30 minutes. The trip takes 45 minutes and the ticket price is 13.70 euros. After getting off at Opera, you can walk to your hotel near Opera or Saint Lazare Railway Station. So, you do not need to take a taxi or to carry your luggage down to subway. If you take a taxi, the cost from the airport to Paris is at least 50-55 euros.
In case you take a hotel far (or not in a walking distance) from Opera House and Saint Lazare Railway Station, then you need to take a public transport (bus, metro, or taxi) from Opera House to your hotel. You may have information on them here:
