There has been some discussion on the Civil Spotters group about the best e-mail address to use if you want to obtain a photography permit for visiting Paris Charles de Gaulle airport. The best address to use is Le Commandant Xavier Huby at:

xavier.huby@seine-saint-denis.pref.gouv.fr

The amount of time it takes to receive passes seems to vary, but it’s generally accepted that once you have a pass it does not expire.
