JAL disposing of their contract crew is related to their Government backed loan. If they didn't make the cuts, the didn't get the money and when you're in that situation the focus is likely to be on the foreign/contract staff.
For CRJ experience; The company is carrying a severe problem child that came from CRJ's, so that effects their inclinations in hiring. Strange logic, "CRJ guy is a problem, no more CRJ guys, no more problems"
Good luck to all.
