The June awards haven’t been published yet, but the most junior line holder for May was an August ‘18 hire. I would expect that to come down a bit as pre-covid flying gets fully restored. The most Junior DEN FO is a March ‘20 hire (the last class before the world blew up). You should be able to hold any base pretty quickly if you aren’t able to get it in training. Full disclosure though... with opening new bases, the initial staffing will usually come from other bases. Denver traditionally being the hardest hit on the junior end. Denver downsizing has been talked about for a long time and it’s yet to be known if the crew positions pulled from Denver over the past year will be restored. So, if you have your heart set on Denver, be prepared for some turbulence in your relative base seniority and the possibility of being displaced to another base until you are senior enough to bid back. Also, the future is never written in stone, don’t plan on upgrading in Denver unless you plan to voluntarily stay in the right seat for 15+ years.
