Has anyone here flown with a layover at Reagan National (DCA)? The least expensive for us out of Bangor right now has a 35 minute layover at DCA, flying US Air. We will be arriving in a smaller commuter Jet and changing onto a bigger plane. I know at some airports the gates for the different size planes are on totally opposite sides of the airport, but when I look at the map of DCA it just shows US Air in the one terminal. Do you think 35 minutes is enough time?
