Allegiant Airlines, a discount carrier that flies out of many smaller markets to major tourist destinations is offering the opportunity to win free flights for four years. The sweepstakes is available through liking the airline on a Facebook app. The sweepstakes runs through September 28, 2012, and the Grand Prize for the event allows users to fly to a destination that they choose up to 12, yes, 12 times per year.
