Basically you need to submit a recommendation for something to do in Washington DC via Twitter to Brussels Airlines, and they’ll pick their favorite one. You’ll need to access the link that I provided above which will take you to the image you see here. You’ll need to retweet that picture along with your suggestion and a hashtag to #WELOVEDC in order to enter.
The winner will be selected during the inaugural event ahead of Brussels’ maiden flight from Washington DC to Brussels on June 18.
