I want to fly BOS <-> DAY and I have the option to connect either via PHL or DCA (on US). Any preferences? I've connected through PHL in the past (I don't mind the airport / terminals, I do mind the weather that causes havoc at the airport though). I'm considering DCA given that US has the frequent BOS <-> DCA shuttle which will give me a few more options if I miss a connection. Do you think it would be an improvement over PHL?
