Of course if you are ex FLIGHTCREW then you will undoubtedly get a job as soon as you walk in to civvy street. Thats not what the guy was asking though. He asked if it was possible do some sort of grouncrew techy type job and whether that would be an advantage to getting into an airline.
Myself and 2 friends happen to come from a certain 'disciplined' background as you put but but it hasnt made the slightest bit of difference when it comes to the front of the job queue. The vast majority of airlines want ticks in the boxes, loads of hours in the log book, and people who can start start straight away. Perhaps the bigger boys(your BA's, Easy, etc etc) will undoubtedly be more interested in your background but theyre not exactly first job material are they.
