Mark,
 
So, what you are saying is that ATC has a better command and control process 
for the movement of the airline’s $100s of Billions of aircraft assets than the 
airlines themselves.
 
This is so wrong on so many levels.

This is actually an interesting corner of air traffic management. Airlines will 
sometimes ask FAA to implement ground stops or other ATM initiatives that the 
carriers could theoretically carry out themselves, because FAA has processes 
and systems in place to do this more easily.

Good question. Maybe "Advised" rather than "sought". No way is it necessary to 
get FAA approval. Air Traffic might appreciate it for their own planning.

Alaska had to apply to FAA to not fly? Per below: 


"According to an FAA advisory, the airline sought approval to ground over 200 
planes under its brand. It later expanded the stoppage to include planes from 
its Horizon Air unit. Alaska Airlines said the decision stemmed from a computer 
network outage. While the ground stop was lifted about three hours later, 
around 11pm Pacific, Alaska said that “residual impacts” to its operations 
would be felt, adding, “It will take some time to get our overall operations 
back to normal.” As NBC News noted, the disruption comes almost exactly a year
