Do you mean Falls Church, Virginia? If so Dulles, IAD, washington National Reagan are both nearby, although National could probably get you to Falls Church via the Metro

i`ve been to falls church many times & each time i flew to dulles. i guess it would depend if there was someone to pick you up from the airport. like suggested before, you could go to national aiport in DC & then take the metro into falls church if you had no ride.

Continental Airlines flies non-stop from IAH to Reagan National. From there, it is easy to just take the Metro to Falls Church. Joan
