Passenger airline services are located at Daytona Beach International Airport (DAB), which is centrally located within the city adjacent to Daytona International Speedway. The site was first used as an airport with terminals being constructed in 1952 and 1958. The present facility was constructed in 1992 at the cost of $46 million, and includes both a domestic terminal and an International terminal. Despite the new facilities, DAB has found difficulty in attracting and retaining carriers; Continental Airlines, AirTran Airways, and United Airlines discontinued flights to Daytona in 2007 and 2008. LTU & American Airlines also serviced Daytona Beach during the 1980s and 1990s, both of which ended all flights in 1994 & 1997.
