That was pretty fast United, nice job, quicker than most ramp closures during thunderstorms!

I may have been wrong. It’s starting to look like that.
Edit: I’m mostly seeing UAX flights take off. I know those got exempted leaving hubs. The problem is all the UA gates in hubs are clogged so UAX can’t fly their inbounds until those are cleared.

REMARKS: UAL AND SUBS ONLY. IAD UAL SUB DEPARTURES STILL EXEMPT.
UNLESS YOU HEAR FROM DCC FIRST, THEY ARE STILL STOPPED. ALL FLIGHTS
REQUESTING OR CLAIMING EXEMPTION ARE NOT EXEMPT.
The way I read that...UA subs (UA Express) out of IAD *are* exempt. So if they are claiming exemption then they are correct and they are exempt. "IAD UAL SUB DEPARTURES STILL EXEMPT" overrules the rest of that posting which would apply to all UA flights at every airport in US/Canada and UA mainline at IAD (given that subs are exempt).
So either that's a typo and they meant to say "IAD UAL sub departures still stopped" (meaning there is no exemption for them) or what I wrote above is true.
Doesn't matter now as the ground stop has been lifted as of a few minutes ago.

Sounds like they were trying to avoid overwhelming both hub and spoke airports because any more flights airborne would eventually contribute to ground congestion (and eventually, if it lasted long enough, excessive tarmac delays). That's probably why subs were allowed to be exempt because they wouldn't quite contribute to the same problem.

They dug themselves out of it quite well. I guess it’s all their experience over the years of doing this to themselves. Will be a fun couple days for the poor souls assigned to root cause and mitigation reports. They put in a code freeze so IT can catch their breath but looks like everything is calm now.
