In Limbo,
I will probably be corrected but I believe you and your family are entitled to 1 "free ticket", airport taxes you have to pay, on any of GF routes. If GF does not fly to your place of recruiment then the nearest International airport from point of recruitment on another airline. If you fly to your "Home land" then this can be B3 ie Have to fly. If you are in a position where your Leave has to be split you are entiltled to a second leave tickets which is firm but B7, however this only applies to GF routes.
Housing a sticky point at the moment throughout the Gulf.
