Paris airports operator ADP said on Monday its January traffic fell 7.8 percent compared with January 2008, due to bad weather conditions, a national one-day strike and the global economic slowdown.

Traffic at Paris Charles de Gaulle Airport fell 6.5 percent while Paris-Orly Airport traffic was down 10.7 percent.

The group said international traffic dropped 4 percent while domestic traffic was down 4 percent.
