yknot,
there is a psychological name for what I will try to describe but I can't for the life of me remember what it is called. Simply put, if you dont get something you want you create the opposite view of it in your own mind. If a girl you like says no or dumps you, you decide she was a biatch and that she wasnt worthy of you anyway.
Not too many people handle rejection from an airline. I have seen a few friends get knocked back from CX. Their egos battered, they decided never to apply again. Even if CX recruitment had responded to nolimitholdem it wouldn't have changed his view. He would just be a little more smug in accepting his second choice career.
yknot, there are lots of reasons why people get knocked back. Often it is age vs experience...late starters have lots of catching up to do. Or just too inexperienced in the first place. Personality wise we all change over time so sometimes we can't see any difference but suddenly we get accepted.
Unless it was made clear to you never to reapply, reapply.
Good luck!
