Berlin Tegel Airport Airport. Note that the Alt-Tegel U-Bahn station and Tegel S-Bahn station do not serve Tegel Airport, but rather the Tegel-quarter of Berlin. Currently (2017) an extension of the Berlin Straßenbahn from Hauptbahnhof to Tegel Airport is being discussed but it is unclear whether this extension will open before the closure of the airport. The airport has a direct connection to motorway A111 (Exit "Flughafen Tegel") which further links it to motorways A10, A110 and A115 (via A110) reaching out in all directions. Taxis and car hire are available at the airport, the city center (Alexanderplatz) can be reached within 25
Airport city Airport city Airport city is the "inside the fence" airport area including the airport (terminals, apron, and runways) and on-airport businesses such as air cargo, logistics, offices, retail, and hotels.

The airport city model recognises that an airport can do more than perform its traditional aeronautical services, evolving new non-aeronautical commercial facilities, services and revenue streams. Airports are now routinely targeting non-aeronautical revenue streams amounting to 40–60% of their total revenues. Industry leaders and researchers share best practices on non-aeronautical revenues
