I went to CCS last week to pick up a friend who was arriving from MIA. While waiting for him in the arrivals area, I saw many pax that arrived from CDG with AF. I saw a family who had their bags checked CDG-CCS-MAR. That's Paris-Caracas on AF and then Caracas-Maracaibo with Aeropostal. They were also holding tickets that said Caracas-Maracaibo.
So after looking at that... I ask you all: is there a codeshare agreement between Aeropostal and Air France? Why can Air France give out Aeropostal boarding passes and check their luggage in CDG for a domestic venezuelan flight? Any ideas?
