Hawaiian is trying to do the right thing and improve their hiring processes. They're attempting to be responsive to the feedback from applicants that they've been left in limbo after applying or participating in various phases of the interview. The email feedback is pretty direct, but at least a guy knows where he/she stands. Hawaiian is not a good fit for everyone, but is an excellent career for some. (see previous threads)
If you understand the island / culture / cost of living / etc., and are otherwise qualified, watch for the application window to open and reapply. Best of luck to all.
