Not to pile on, but (I will anyway), morning weather in Atlanta has been horrific. Flew up to DCA on the 2nd flight Saturday AM and nearly every flight into and out of ATL was delayed or cancelled, and there was a ground stop for planes departing for Atlanta for about 1.5 hours. Actually the earlier flight (8:30am and mine was 10:12), only got out 10 minutes before mine in the end and both were late (I left at about 11:30) due to either inbound aircraft and/or crew delays. My plane was waiting in Gulfport, MS for the ground stop to be lifted to come to ATL and get my flight to DCA. No need for conspiracy theories. At least not yet. ;-)
