New Route: Houston to Aruba on Southwest Southwest Airlines has set its eyes on the lucrative international market. Starting March 7, Southwest customers will have access to Houston–Aruba with Saturday-only flights. The new Caribbean route also points to Southwest’s other ambition: expanding into the Latin American market. In December, the airline filed applications with the Department of Justice (DOJ) to fly from Houston to four popular Mexican vacation spots: Cancun, Los Cabos, Mexico City, and Puerto Vallarta, as well as Belize City, Belize, and San Jose, Costa Rica.
