What seniority do the most junior CA line holders have? About 3+ years depending on the base. How long will will the 6 month CAs be on reserve especially as FOs senior to them get their 1000 121 time and upgrade keeping them at the bottom of the CA list? Probably quite a while. Reserve at PSA results in a very poor QOL. Most of the new hires either got a line out of training or sat reserve for a week or two. They will be in for a pleasant surprise when they have to sit reserve for an extended period of time. The guys who got hired 1-1.5 years ago had excellent timing and will make out very well. Not so much for those getting hired now, depending on what their goals are.
