I heard from a pilot who was there last night, it was a real mess, lots of cancelled flights due to de-ice problems. Every time it snows in ATL it's like they have never seen it before...

This morning there have already been over 250 cancellations in ATL, my boy arrives from Zurich at 2:30pm but all the flights to Florida (MIA, FLL, PBI and MCO) are -way- overbooked because of the "snowball" effect of last night and this morning's cancellations.

Oh, and it's MLK weekend, already a very high travel time to Florida.
