Because I had the joy of making the correspondance between CDG and ORY on my recent flight to Corsica on Air Corsica, I will just add a note that while the XK flights check-in with the rest of the AF flights in Orly 3, the boarding gate was actually in the old Orly 2 C-gates. In my case, next to an easyJet flight departing at roughly the same time.....making for no space in the seating area

A picture of the new Orly 3 check-in area:



I didn't find the new layout too hard to navigate though (arrived via le Bus Direct).
