Just to add to trollydolly's comments...
I don't think UA will be hiring F/As for a long time. The longest voluntary furloughs (VFs) go through spring of 2007, which is when the bulk of the VFs are scheduled to return. I can't imagine they will want 3,000 VFs returning at the same time so the planning right now seems to be they won't be hiring AT LEAST until 2007, and they will probably have to extend some of the furloughs even past that date because they won't want 3,000 dumped into the system all at once.
But who knows... they could decide to recall all the VFs next month and start hiring the month after that. Or they could do another round of additional furloughs tomorrow. Anything's possible these days.
