After reading this thread, I thought it only fair to see if I could get you some information about on-line applications, etc. So I just got off the phone with one of our flight operations administrators (FOA) (their job is as an assistant to the aircraft specific chief pilots) and also the woman who administrators the pilot application pool.

Here's what I learned:
. From the FOA: she thought that we'd not be hiring until 2009.
. From the pool administrator: she says: a) that the on-line system is in fact down for maintenance and should be up by the end of the month; b) applications are good for between a year and two years without being updated; c) in her 8 years of working in this job, she can remember the system being purged of applicants only once or at most twice; d) she thought we'd be hiring in 2008.

Hope this helps. Good Luck.
