This document outlines the rules for IBERIA's #Tweetowns contest on Twitter. The contest will award two trips - one to Madrid for followers in the Americas, and one to Guatemala for followers in Europe. To enter, followers must tweet the hashtag #tweetowns along with the shortest list of Panamanian and/or Guatemalan cities and towns separated by semi-colons. Winners will be chosen based on submitting the list with the fewest cities that are IBERIA followers. Winners will be announced on Twitter within a month and must contact IBERIA within 5 days to claim their prize.
