I may be traveling through DCA this summer. The first flight operated by US Airways, second operated by United, and will probably have to get to the other gates in terminal C. When I was last at DCA I recall a shuttle bus that took you to the other side. Is it still there? If so does anyone know the gates it operates from? I think one of the gates is 36 if I remember correctly? Do you have to request it? I'm just trying to figure things out because I've never had a connecting flight alone and I don't want to get lost, or have to go through security twice, for that matter
