Miami-Opa Locka Executive Airport — Miami, United States

OPF is Miami-Opa Locka Executive Airport, a busy general aviation and corporate airport located in Opa-locka, Florida, part of the greater Miami metropolitan area. OPF is one of the busiest general aviation airports in the United States, handling significant business jet, charter, flight training, and cargo traffic that would otherwise burden Miami International Airport. The airport has a distinctive history tied to aviation pioneer Glenn Curtiss and later served as a Naval Air Station during World War II. Today OPF supports numerous fixed-base operators, maintenance facilities, and flight schools, making it a critical piece of South Florida's aviation infrastructure despite lacking scheduled commercial airline passenger service.
