1. If you follow the national airspace system closely, as I do, you know that there have been a number of seemingly inexplicable delays/ground stops since the shutdown started
That said, controllers work in shifts, and unclear what staffing impact will be later in the day.
Inbound, EWR showing average of 61-minute delays due to wind. LGA still showing 86-minute average.
Controllers are maxed out at 10 hours a day, 6 days a week (and many do just that).
