Low-cost carrier Southwest Airlines launched a new international route from Houston’s Hobby Airport to Aruba last weekend—the first in a series of destinations the company plans to service in 2015.

For now, the Aruba destination will remain seasonal and operate every Saturday until August 8, 2015. Southwest plans to expand its international flight service from Houston this year, adding stops in Belize, Mexico City, Cancun, Cabo, Puerto Vallarta, San Jose and Costa Rica.

Currently, the airline is investing $150 million in Hobby Airport to add five new gates for international travel. Construction on the new wing is slated for an October 2015 completion. In the meantime, international travel to Aruba is made possible through U.S. Customs and Border Protection’s pre-clearance operation in Aruba.
