Other trips include $130 one-way from Atlanta to Las Vegas or $132 one-way from Atlanta to Los Angeles; $59 one-way from Columbus, Ohio, to Washington; $69 one-way from Fort Lauderdale, Florida, to Nassau, Bahamas; and $135 one-way from Austin, Texas, to Seattle.

Travel & Leisure reported that most sale prices are on Monday through Thursday flights between August 22 and December 16.
