Erfurt-Weimar Airport lies 3 km (2 mi) west of the city centre. It is linked to the central train station via Stadtbahn (tram). It was significantly extended in the 1990s, with flights mostly to Mediterranean holiday destinations and to London during the peak Christmas market tourist season. Connections to longer haul flights are easily accessible via Frankfurt Airport, which can be reached in 2 hours via a direct train from Frankfurt Airport to Erfurt, and from Leipzig/Halle Airport, which can be reached within half an hour.[citation needed]
