The grid system doesn’t require reserves to be flogged, but most of the the decent stuff was there has been dismantled over the years. The prevailing sentiment for years while growth was at an exponential rate was you spend 2 months on reserve as a new hire and maybe 3-6 months at captain upgrade and then the rest of your career as a line holder. I’ve met a few captains here that never spent a single day on reserve in either seat at Spirit (and didn’t bypass upgrade). So reserve QOL was never a top of the list item in previous negotiations, and few pilots batted an eyelash as anything good left was eradicated. Merger aside, there could be a number of reserve quality of life improvements to existing NK work rules that would have zero impact on the grid/dtz, but there’s not a ton of enthusiasm around spending negotiating capital on that… except for the bottom 20% of captains in each base.
