Why do you want to go to IAD versus BWI since at BWI you can just take
the light rail to your hotel?

Last time I went from SFO to that area BWI was the cheapest airport for
flights, plus they had the cheapest rental cars. Now BWI seems to be a
tad more expensive since Virgin America and Air Tran are competing at
IAD, so BWI is about $30 more.

In general there are many more nonstops from SFA (San Francisco area) to
IAD than to BWI; and all the one-stops SFA - BWI are several hours
longer total flight time, plus the hassle of the connection. (Nonstops
BWI back to SFA are especially scarce).

By contrast, United (which is my primary FF carrier) has multiple daily
nonstops both ways SFO - IAD, thus giving me more scheduling choice,
plus backup options in case one of these flights gets cancelled or
delayed.
