There's definitely a disparity among the various BES. I'm at day 115 since I last turned a wheel. 2 FSBs and a landings class is all I've done "outside" the house. Lots of unused SCs thrown in there. I thought for sure I would be flying over Christmas, but I dropped dead for landings on 9 Dec and did not go to Landings class until 26 Jan.
I'm at 49% in base as DCA 756 FO. I fully expect to be busy this summer. I bid reserve during the school year intentionally. It's nice to be around for a lot of the kids' events.
I understand my example is on the other extreme in comparison to the aforementioned examples.
