I quickly compared the Flight Delays for BWI(Baltimore Washington International) with IAD ( Washington Dulles Airport) And there was a world of difference. BWI showed all green And IAD was almost all red, yellow and black. The colors denote the delays.
Green 0-15 minute delay
Yellow 15-60 minute delay
Red 1-2 hour delay
Black More than 2 hour delay
It is a good Google MAps mash up with Data provided by FAA. Very simple functionality - search by airport or by zip code. I put in my zip code and it did not ask me for my preferred airport (BWI) but defaulted to IAD.
If I am at airport and nothing to do I would be browsing this site
