Scrogg's - Sorry i have to disagree with you there - this is NOT based on rumour.
Having got extensive airline experience and can say that this is the case with most of the operators i have worked with - BUT as i said it does depend on what type of military flying background you have - a airline is more likely to take on someone who has flown large multi engine military a/c eg Herc/VC10/Tristar etc rather than a pilot who has flown a/c such as Jaguar/Tornado etc.
One thing on which i will agree on is that the main carrier's that employ ex military guy's - the largest are Brittania/Virgin and Monarch.
So on this subject i think we will have to agree to disagree.
