After years of delays, the new Berlin Brandenburg International airport terminal opened across the runway from the old terminal building in Schönefeld in 2020.

As can be seen on the map, Schönefeld is on the southeastern edge of the city. That makes it convenient for going to Union, but quite a trek to get to Hertha, as the Olympic Stadium is way over to the west of the city centre in the district of Charlottenburg. It can therefore take over an hour to get from the airport to the stadium on public transport. 

To the Olympic Stadium
The simplest way of getting to the Olympiastadion, requiring no changes, is to take the S9 heading for Spandau. You can get it from the station directly below the terminal, and it will take you straight to the stadium in 1 hour and 10 minutes.

You can reduce the journey time to around 55 minutes by taking a mainline train, e.g. the FEX Airport Express, into town and changing there, for instance at Ostkreuz, to an S-Bahn, e.g. the S5.

To the Stadion an der Alten Försterei
You can get to Union's stadium by train and tram in about 30 minutes. For instance, by taking the FEX Airport Express from the station below the terminal to Schöneweide and from there tram number 60 to right outside the ground (tram stop 'Alte Försterei). 

Alternatively, you can get to the other side of the ground in around 45 minutes by taking the FEX to Ostkreuz and then the S3 S-Bahn (destination Erkner) to Köpenick S-Bahn station, from where it's at most a 10-minute walk to the ground.

To get, instead, into the centre of the city takes around half an hour. 

You can plan your journey from the airport via the Berlin local public transport website and plan journeys and buy tickets from your phone via their app. The trains and metro (S-Bahn) services depart from the station platforms directly beneath the terminal.

Note: Nearly everywhere you'll go in Berlin lies within zones A and B of the VBB public transport network. However, the airport is in zone C. When travelling to or from the airport, be careful therefore not to get caught by ticket inspectors without a ticket valid for that zone!. If you have a rail pass like Interrail (valid for trains and S-Bahn) or the Deutschlandticket, you'll be covered. If not, a Berlin WelcomeCard is not a bad idea, as it gives you unlimited use of public transport, including in zone C (if you buy the right version), and discounts on many places to see and things to do.

If you are going to a Hertha game and already have your match ticket, it entitles you to travel free on local public transport within zones A, B and C (so all around Berlin, including the airport) from 5 hours before kick-off until 3am next morning. See the club's Ticket FAQs.

If you are going to a Union game, you need to buy your local travel ticket(s) separately, as Union match tickets do NOT include this.

If you're planning on picking up a hire car at the airport, the best-known rental firms operating there are Avis, Budget, Hertz, Sixt, Europcar and Enterprise. Their desks are on level E0 of Terminal 1. You can see which offer the best prices here at Rentalcars.co.uk.
