From DCA to Ballston it is $20-21 with tip. One note on Red Top though, I did that one evening after a delay and a literally 300 person long cab line

-- all the seprate lines 300 people.. I called and they could not provide an estimate.
I had a trick and got a cab, cancelled to cancel Red Top and couldn't get through. About 2.5 hours after landing, they called to alert me my pickup was there.
