fly small airplanes
OP, your first post implies that you do not see the way for daughter to fly large airplanes....currently. In that case switch the job search to small airplane operations, hunt intensively, start with virtually anything offered, always ready to move for small improvement, build some airtime soon as you can, thus build confidence and experience........the airline slot may or may not be offered in future but some people do have a useful career in general aviation.
