Southwest launches $25 fare sale

DALLAS (AP) - Southwest Airlines has launched an air fare sale in which some flights cost the same as what other carriers charge to check a bag.

Dallas-based Southwest on Tuesday announced one-way travel as low as $25, based on the length of the flight.

The discount carrier said fares are $25 for travel up to 375 miles.

The cost is $50 for travel between 375 and 549 miles, and $75 for flights between 550 and 999 miles. A one-way fare of more than 1,000 miles costs $100.

The fares are available for purchase through Thursday, for travel between Dec. 2 and Dec. 16, or between Jan. 5 and Feb. 10.

Other restrictions apply.
