High Quality Content by WIKIPEDIA articles! Orlando-Sanford International Airport (IATA: SFB, ICAO: KSFB, FAA LID: SFB) is a public commercial air service airport in Sanford, Florida, near Orlando. It was originally constructed as a military installation known as Naval Air Station Sanford that was in operation as a Master Jet Base for carrier-based attack and reconnaissance aircraft until 1969. Due to heavy flight training operations at the airport, it is consistently in the top 30 busiest airports in the world in terms of total flight operations (takeoff and landings). It functions as the Orlando area's secondary commercial airport, but is located farther away from downtown Orlando and the attraction areas of Walt Disney World, Universal Studios Florida and SeaWorld Orlando than the larger, primary airport, Orlando International Airport (MCO/KMCO).
