The Brownsville/South Padre Island International Airport is the closest - situation about 22 miles from South Padre Island. Continental Airlines has frequent flights into B/SPIIA. To cover the ground distance between Brownsville and South Padre Island, visitors have the options of car rental, taxi or airport shuttle to choose from.
Although it is located a little further away (about 40 miles from South Padre Island), the Valley International Airport in Harlingen actually sees a little more traffic when it comes to visitors headed to SPI. This is primarily due to the number of daily flights Southwest Airlines flies into VIA from Austin, Dallas, Houston, San Antonio and elsewhere. Continental and Sun Country also fly into VIA. And, like Brownsville International, VIA offers car rentals, taxi service and airport shuttles to complete the final leg to South Padre Island.
