That’s a case by case basis DPE dependent on a frames age/cycles/condition. The used Southwest tails that United picked up pre-Covid became parts birds. But I will 100 percent bet if United had an opportunity to pick up relatively young NEO or Max frames, I believed they will send them through conformity check.
