There are two airports that you can use for coming to Girona.
Girona airport (GRO): Aeroport de Girona
Barcelona airport (BCN): Aeroport del Prat de Llobregat
The most convenient is Girona airport because of the closer distance, but there may be less flights to it from the different places in and outside Europe. Check possible flights with SkyScanner.

Fast Train from BCN Sants station
The regular slow train connection from Airport BCN leaves from BCN Terminal 2 (T2), see below.

Tickets for fast trains can be bought beforehand (conference discount codes will be available in February 2016) through the Renfe website.
Alternatively, there is a train connection from BCN Airport to Girona Station involving two lines.
First: Take the free Transit bus from Terminal 1 to Terminal 2 (15 min.).
Second: Walk to train station (10-15 min.) from within Terminal 2B (upstairs).
Third: Buy directly a ticket to Girona at the counter (not available on the machines probably).
Fourth: Every half an hour (xx.08 and xx.38) a train leaves.
Fifth: Get off at Passeig de Gracia (one stop AFTER Barcelona Sants)
Sixth: Depending on the hour you’ll have to wait between 20 and 50 minutes, then take the direct train to Girona.
