While I agree it is disingenuous to tell people in the District to just drive out to IAD, as someone who has a base close to IAD I have to say it is a very easy airport. From leaving Reston I am past security and heading to the gate in less than 20 minutes, counting car rental return. PreCheck is always open and never a line more than a few minutes.

Anyhow, it's clearly been posted now that there are flights from DCA to the west coast. You don't have to drive out to IAD, unless you want to go to Europe or certain destinations south of the border.
