PSA is not having trouble filling classes at this point. Did you even read the rest of the thread?

I don't know where this rumor came from. I haven't heard it.(which doesn't mean it's not true)

We have plenty right now with the requisite 121 time to upgrade.

At the current pace of upgrades it would take probably 6 months or so to get to some very low longevity guys. During that time more and more pilots are going to reach the required time.

There are also a pretty hefty amount of senior FOs bypassing upgrade right now for vacation or not wanting to be on reserve.
