certainly possible if a bunch of senior FOs senior to 24xx Capt upgrade and they don’t wanna commute if all the 23xx and more senior they certainly could be displaced with no CA left junior to them

no ones knows how it’ll play out we will find out in the new year

in the JCBA I would not mind some first dibs processions for existing captains in a displacembt bid, they took the risk and QOL hit to upgrade early
