You're correct about transition. May this year is insanely different than last year even though I'm sure it's not all due to TX. As far as upgrades and PBS go I don't think it's really going to slow things down much because our lack of frequency won't allow for utilization that would reduce the need for upgrades. If we had 500 airplanes it would, but it's just not a factor at this time for us. That said anyone wondering why upgrades have dropped off so bad this month just need to look at the reserve grid for the answer. Captains are green and FO's are red. It's the busy season so you spend the sim time getting more FO's trained and when the slow season hits you get more captains trained.
