I don’t think there is any way to “project pilot fly” a fleet for 6 months. It will probably be 1-2 bases initially and there is precedent for that. When DL got the MD-90 I think CVG was the first base. Then it quickly expanded to all the 88 bases. Given that the 321NEO was mostly train by memo, I doubt the MAX spool up will be logistically challenging at all. While not the exact same situation, there’s already 2 sims for it ready to go on day one. From the day the first one enters revenue service I doubt it’ll be a year before all bases are fully qualled to fly it. Most likely 6 months or so max. Not a big deal.
