If you are a US Airways flyer who frequents DCA at all, you are very familiar with the craziness of gate 35a and its shuttle buses.
But soon, you will be able to board the commuter flights in DCA through an enclosed area.
The capital construction program includes a new commuter concourse to provide enclosed facilities for the 14 outdoor boarding positions for commuter planes, which currently are accessed with bus service at Gate 35X.
Gate 35A was recently expanded to allow passengers to wait in the boarding area before their flight is boarding. Previously, you could not go down the escalator into the boarding area when your flight was not boarding. Now you can linger there.
This would be an even bigger improvement and frankly, erase the stress from worrying about getting onto the wrong shuttle bus.
