hi!!
im a french atco..here we get 6 flights per year with about 30 to 70% off the ticket actual price ,you have 3 with rexervation and 3 no reservation possible..its called "gp" as "gratuit partiellement" ie partially free..
you can only use those on flights with airfrance and members of skyteam
not really easy to use ..you have to order those through an air france agency..
thats why im never use mines..because on short haul flights air france youngsters prices are sometimes more intreressting!!but apparently some of my colleagues do and enjoy it..
if u got for the non resernation way,you better consultate the frequentation of the flights at the time period you want to go,if not you stay sometimes stuck at airports waiting and waiting for a free seat...
hope i answer your question...
we dont get them to give advantage to the national compagny;but because we are civil servants..
xx bye cam
