FareCompare introduced a Twitter beta today that mashes-up Google Maps, FareCompare deal tweets from consumers’ favorite departure airports and Twitter users who are following those alerts from selected airports.

Fare alerts on social networks like Twitter and Facebook have become a hot arena as companies like FareCompare, Travelzoo, Travelocity and countless others vie for bookings and the allegiances of deal-hungry consumers.

FareCompare’s Twitter beta takes the competition to the next level by attempting to further engage consumers with a Web 2.0, community-oriented flavor.
