it would be interesting to see what happened if both F9 and US went under. that's a lot of slots right there. i love DCA...actually came back from SMF last friday on the PHX-DCA flight. very convenient to get my back and get down the metro one stop to braddock road and i'm home. best part was going to DCA, time from walking out my apartment to metro to walking into DCA? 15 minutes. i love it.
