As HVYMETAL also states...
Recruiters aren't stupid, and nor are reputable Airlines, they can spot a P2F RHS a mile off when applying for a position and they will be bottom of the pile, not because they paid for their previous employment but because they are usually of poorer quality than other (non P2F) candidates as has been the experience of the airline concerned, and good airlines want good candidates with good known quantity backgrounds.
Not to mention liability... if you are involved in an accident and somebody digs.
