"DCA" or "National" (it's never called Reagan by locals) is definitely the best place to fly in or out of when you're living in or visiting DC. It's immediately accessible via the Yellow and Blue lines (though watch out on weekends when Yellow line trains are running on a limited schedule). I have TSA PreCheck, so I can't really speak to how the normal security lines are, but the PreCheck here lines can get pretty long considering DC's home to a lot of frequent travelers.
