According to MTA's website, the Penn Line connecting DC Union Station and BWI runs only Monday-Friday. But if someone else has more recent info than the 2014 schedule I saw on the site, please post it.
On the weekend, it looks like if you're not willing to shell out for Uber (~$30-$60 from DC), then the WMATA route is your best bet.
