PSA upgrade is basically as soon as your done with training if you have 1,000 121 time already. Half of my class from earlier this year have already upgraded and a handful have moved on to LCCs and legacies. Upgrade seems to kind of bounce around based on the bid award for any given upgrade class. A couple have gone a little more senior as FOs that have been on property for a while decide to upgrade. But it's generally quick.
