CHICAGO (KTRK) -- Looking to get away? Southwest Airlines wants to help you hang on to summer with cheap flights to Mexico and the Caribbean this fall.

Starting Tuesday, travelers can book one-way flights to destinations like Belize, the Dominican Republic and the Cayman Islands for as low as $59.

Sample fares from Houston's Hobby Airport include $99 for a one-way ticket to Mexico City and $128 for a one-way ticket to Belize City.

The cheap flights are for October and November, but you'll have to act fast - the sale only lasts through Sept. 20.
