DFW been an absolute mess (as is the whole AA system). 23% cancellation rate, planes stuck on the tarmac for hours and hours due no gate (i.e. lots of ramp and gate employees understandably couldn't make it in), FA's stranded all over the country for days with no accommodations and what appears to be IT meltdown today. . Evidently, operations keeps going with these rolling delays thinking crew are in places where they are not. Ugh!
