If you are thinking of applying to the more established airlines, then it is a good idea to have some "history" of interest. I would suggest that you make an initial application, and then provide regular, say six monthly, updates. When you are fully qualified and are hopefully invited to an interview, then your file should be of a reasonable size and interest to provide for a pleasant discussion. Airlines are well used to standard C.V.'s which are pushed out to test the waters, hence the suggestion for some long term planning and enthusiasm for whichever airline(s) that you desire. Good luck.
