Alexandroupoli Democritus Airport (IATA: AXD) serves the city of Alexandroupolis in the Evros regional unit of northeastern Greece, near the borders with Turkey and Bulgaria. Named after the ancient philosopher Democritus, who is traditionally associated with the broader Thrace region, the airport connects the area to Athens and other Greek cities as well as select international routes. The airport handles both civilian and military traffic, reflecting its strategic location in a sensitive border zone. Passenger volumes are modest compared to major Greek airports, but it serves as an important transport hub for the wider region of Eastern Macedonia and Thrace. In recent years, the airport has seen investment as part of broader Greek airport modernization efforts. Fraport Greece, which manages a portfolio of regional Greek airports, took over operations at Alexandroupoli as part of a concession agreement.
