The problem is that a large group of air traffic controllers walked out. They did not get the support they needed. You are focusing on only one small aspect of the problem. And as it relates to that problem, I ask you, why did Trump not fix this during his last term?The problem is not with understaffing of office personnel.
It’s with ATC’s who are qualified to work at high capacity airports or ARTCC’s at high capacity en route centers.
Give it up, you are novice at this and it shows.
