Freezing rain, sleet, and snow from Texas to Virginia affecting travel today.

Alas, the image changes with the changes in weather alerts.
Airports from Houston to Charlotte have been cancelling flights. Hartsfield-Jackson Airport in Atlanta, the busiest airport in the world, has cancelled more than 800 flights, which is over a third of today's schedule.

Today would be an excellent day not to fly through any airport in the region. CNN has a story.

The Weather Channel has a state-by-state rundown. The National Weather Service's winter storm warnings are here.

Yes. See https://en.wikipedia.org/wiki/World%27s_busiest_airports_by_passenger_traffic. Top five for 2012 and the first ten months of 2013 were ATL, PEK, LHR, HND, and ORD, in that order.

(Full disclosure: I edited the 2007 and 2008 tables in that list a while back to fix some transcription errors.)
