LOL you gotta be trolling. There’s a reason so many regional FOs only use spirit as a type ride to get a call from the legacy carrier. Everyone talking about QOL at spirit like there isn’t an attrition problem with pilots leaving to other airlines that don’t have the dropping to zero stuff everyone is raving about. So no a spirit airline pilot should not gain any relative seniority, even keeping it a relative seniority shuffle favors the spirit pilots massively. There should also be a slight factor of what airline is getting purchased added to it. I know so many think the ULCC is a way of life but again Spirit is getting purchased. CASH! Not as high and mighty as you may think.
