Ciudad Acuña International Airport — Ciudad Acuña, Mexico

Ciudad Acuña International Airport, in the Mexican state of Coahuila directly across the Rio Grande from Del Rio, Texas, is equipped with one runway at 1,410 feet above sea level. Its grand international name outpaces the field's actual traffic volume, which lands it in the medium category. Coahuila is a large, largely desert state in northern Mexico, and Ciudad Acuña's position on the border shapes much of its economic and travel activity. Travelers heading further into Mexico's interior get an air option here distinct from the road crossing into the United States.
