Delta is giving free priority boarding to Nationals fans flying out of Ronald Reagan Washington National Airport. All they have to do is wear clothing that boasts their loyalties.

The airline has kept mum on exactly how long this offering will last, though it's indicated that it will go for as long as the baseball team are in the running for the World Series championship title. (The World Series starts Oct. 25.)
