Brownsville was once the main terminal for air service between the United States and Mexico. In 1929,
Pan American World Airways acquired a controlling stake in
Mexicana de Aviación and began
Ford Trimotor service between Brownsville and
Mexico City, eventually extended to the
Yucatan Peninsula to connect with Pan Am's Caribbean route network. On March 9,
Charles Lindbergh inaugurated this service, landing at BRO after a five-hour, 38-minute flight from Mexico City. An event was held on site in Lindbergh's honor, with a crowd of over 20,000 greeting him upon his arrival. Among the attendees was
Amelia Earhart, for whom the main street in front of the Airport is named. Brownsville became an early center for technical development in instrument navigation ("blind flying") due to the bad weather conditions that pilots encountered in the mountains over Mexico. In 1931,
American Airways was flying a multi-stop route Brownsville to Dallas, connecting to Chicago, Los Angeles and other cities.
Braniff Airways began service in 1934, and
Eastern Air Lines arrived in 1939. In the 1960s, the 16th weather
radar system in the country was installed at BRO. In 1982, a new ATC tower was built. In 1983, the airport was renamed the Brownsville-South Padre Island International Airport. A new modern and more spacious terminal was built in 2019-2020, replacing the old, crowded terminal. In 2021, in part as a response to expanding operations by
SpaceX in relation to its
South Texas launch site, a new 91,000 square foot terminal was opened to accommodate an increase in tourism and migration. A further $1.6 million was awarded to the city of Brownsville by the Federal Aviation Administration to enhance the airport's jet bridges. Since March 2022, one of Starship SN8's flaps has been on public display at Brownsville/South Padre Island International Airport. A new long term parking lot was completed in 2024. ==Brownsville Army Airfield==
