The code comes from the airport's former name, Standiford Field. It was later renamed in honour of Louisville native Muhammad Ali.
The airport lies just south of downtown Louisville, typically a short drive away by car or rideshare.
There is one passenger terminal with two concourses, A and B, sharing a single security checkpoint.
Airlines including Southwest, Delta, American and United serve the airport, along with low-cost carriers such as Allegiant and Breeze.
Despite its name, the airport has no regularly scheduled international passenger flights. Travellers usually connect through US hubs such as Atlanta, Chicago or Dallas/Fort Worth.
UPS Worldport is the global air hub of UPS, based at the airport. It is one of the world's largest package-handling facilities and makes Louisville a major cargo airport.
Rideshare, taxis, rental cars and hotel courtesy shuttles are all available from the terminal.
Churchill Downs, home of the Kentucky Derby, is close to the airport. The Muhammad Ali Center and the downtown waterfront are also easy to reach.
Louisville Muhammad Ali International Airport is the main airport for Louisville, Kentucky, in the United States. It was long known as Standiford Field, which is where the SDF code comes from, and it now honours the boxing great Muhammad Ali, who was born in Louisville.
The airport sits just south of downtown Louisville, close to major interstate highways. That makes it one of the more convenient city airports in the region, with a short drive between the terminal and the city centre.
All passenger flights use a single terminal with two concourses, A and B, reached through one central security checkpoint. You will find dining, shops and rental car services inside, and the terminal is compact enough to move through quickly.
Passenger airlines at SDF include Southwest, Delta, American and United, with low-cost carriers such as Allegiant and Breeze adding leisure routes. Most flights link Louisville with other US cities, and hubs like Atlanta, Dallas/Fort Worth and Chicago offer onward connections worldwide.
Louisville is best known in aviation as the home of UPS Worldport, the central air hub of UPS's global network and one of the largest package-sorting facilities anywhere. Its presence makes SDF one of the busiest cargo airports in the world, even though its passenger terminal is modest in size.
For passengers, the upside of a smaller terminal is speed. Walking distances are short, security is centralised, and getting from the kerb to the gate rarely takes long compared with the busiest US airports.
Churchill Downs, home of the Kentucky Derby, is a short drive from the airport. Downtown, visitors head to the Muhammad Ali Center, the Ohio River waterfront and the city's bourbon distilleries.
