I was told during logbook review that the 2 year $100k bonus is not pro-rated and that the company will most likely come after the whole amount unless you go to American even though taxes were withheld. You don’t have to sign the bonus contract. The pay is good anyway.
Republic offers a staggered bonus with no payback clause; last I saw it was 30k after DEC IOE, 30k after a year, etc.
