That's what Jill N. said when I ran into her a couple of weeks ago- there are guys in the pool right now, and the next hiring will be in Sept.
Things do change around here on a weekly basis, though, Monitor Yahoo Aviation Business each day, at

If you see us announce new airplanes and/or new cities, it should affect hiring. If they delay the retirement chedule of the DC9's, but still take 2 B717 month, it will affect hiring . . . in other words, stay informed.
Also, Greta C. used to update her voicemail message when there were significant changes, so if you have her number, check in every week or two, send an update monthly, and stay on top of it. The squeaky wheel definitely gets the grease here.
Good luck.
