Southwest Airlines has a Halloween offer that could make for some really cheap flights depending on where you want to go. I wish Southwest came to Atlanta because they have the best deals on flights! Right now, you can get flights for as low as $30 one way! The price is based on distance, so if you don't need to go far, but really don't want to drive, buy a cheap plance ticket, and save your gas money! Go here to see prices and cities.
The prices are for 72 hours ONLY for travel from December 1-15, 2010 and January 4-February16, 2011.
