Dallas-based Southwest has traditionally flown out of Chicago Midway and Houston Hobby, two smaller airports.
"Today's announcement furthers our commitment to both cities as we add service to share Southwest's value and hospitality with more leisure and business travelers," Southwest Chief Executive Gary Kelly said in a statement.
Southwest last flew service out of both Houston Hobby and IAH in 2005.
