Just a comment and no judgement on APA. They have a hard fight and keep fighting...
...with that said...
Taxi routes in DFW: ER, P, ES, JS, K, JA, B, G taxiways today were horrendous. APA has been slow for years but they've scalled it back to either between "snail's pace" or "parking brake set".
DFW flight reader boards had numerous CANCELLED flights throughout the day on the screens.
I think ATC is getting irritated because they use both Foxtrot and Golf taxiways as same direction flow.
ATC cant do anything cus APA will say they are operating their airplanes safely.
