Budget carrier Allegiant Air is shaking things up in Orlando, where earlier this month they relocated 10 of their 31 nonstop scheduled flights from Orlando-Sanford International Airport to the more centrally located Orlando International Airport. It's a surprising move from a carrier such as Allegiant, operating on the 'low cost' model of serving smaller out-of-the-way airports, which, of course, keeps fares down. So why the move? Competition! Allegiant is up against AirTran, who offers service between Orlando and many of the same small second-tier markets.

Allegiant will continue with the bulk of their service (21 cities) operating from Orlando-Sanford.
