The problem you have just now is that your up against the sheer volume of already airline experienced/type rated peeps that are currently looking for work. Airline recruitment is run by bean counters who look for the cheapest crew thats available.....i.e. those already with TR's and plenty experience, or those who are willing to pay silly amounts of money for a TR and the pleasure of 500 hours to sit in the right seat.
There was however a time when the ex mil guys all joined civvy street and went straight to BA and Virgin. Sadly, those doors closed a long time ago. There was however the ex RAF club at Netjets for those that fancied the biz jet gig. I hear rumours they may start recruiting again after making a large proportion of their pilots redundant a year or 2 ago.
