I've never driven to DCA before, and my friend is flying in this weekend.
For picking her up, I gather DCA has a cell phone lot, so that's fine. She leaves Sunday afternoon (5:30pm), and that's where I'm wondering what to plan for.
How much lead time should I give for her to make it through security and all? She doesn't have status with Alaska (that I know of). Are there any tips for dropping off passengers at DCA?
