I agree DTW is an awesome airport. I don't really mind DCA's old terminal. I like to play the "spot the TWA logo" game when I am in that terminal. j/k. Usually I hang out in the Worldclub (some of the best staff in the whole system!) until 30 minutes prior to departure, breeze through the easiest security line at DCA (longest wait in two years of flying out of DCA exclusively has been 5 minutes), and get to the gate just as boarding begins.
