alt Hacker NewsIf you fly a lot, you might also be aware of the National Airspace System Status: https://nasstatus.faa.gov/
It also has links to a lot of other information useful for people in the airline industry.
I find the Airport Arrival Demand Chart to be good for seeing a big picture of all the flights: https://www.fly.faa.gov/aadc/
I've never seen the nasstatus page, but I have seen the OIS page, which I use frequently when experiencing delays to find out what's going on: https://www.fly.faa.gov/ois/?legacy=true
The links on the NAS page are also really good. nice share!
