The easiest way to get to Berlin is by air. There are two main airports in Berlin: the international airport Tegel, located at the northwestern side of the city, and SchГ¶nefeld in the Eastern Berlin. Tegel is the main hub for major airlines (Lufthansa, Air-France, Pan American, Delta, British Airways) and is also used for many domestic flights. Buses X9 and 109 depart from Tegel airport to Aleksanderplatz, Hauptbahnhof (Berlin Central Station), as well as to Zoologischer Garten (Berlin Zoo). Note that the bus to "Tegel train station" will bring you to a small town called Tegel, not the airport.
SchГ¶nefeld airport serves as a destination for budget airlines and charter flights from Europe. AirportExpress trains and S9 trains depart from Zoologischer Garten to SchГ¶nefeld. The S9 train passes through Aleksanderplatz, Hauptbahnhof and Ostbahnhof.
Berlin is also well-connected to major European destinations by rail, which may be convenient for travellers exploring several countries at once.
