I got a shock today returning at DCA. I had rented from BWI and the 3 WAS metro airports were always considered as one. I guess not anymore, I got hit with a $.35/mile charge. (It was on my reservation, but I didn't notice it) They took it off when I pleaded ignorance. I rented in July picking up at IAD and returning to DCA and this was not the case. Even IAD-DCA is now considered one-way. Does anyone know why and when this took effect and is Florida included? The whole state of FL used to be considered as the same location. The person at the desk said that now any pickup and return from different locations, it doesn't matter where, is now one-way.
