Hamburg Airport is located about 5 miles north of the city of Hamburg. It's a major international airport with a direct rail link to the city centre. BA, Ryanair, easyJet and Eurowings provide direct flights from the UK.

You can get from the airport to Hamburg main station (Hauptbahnhof / Hbf) in 25 minutes on the S1 S-Bahn (metro train), which runs every 10 minutes. 

If you are going straight from the airport to the Volksparkstadion, there are numerous connections available to you, some involving multiple changes. One of the more straighforward journeys is to go via the main station, i.e., take the S1 S-Bahn heading for Wedel as far as Hamburg Hbf (main station) and from there take the S21 S-Bahn (metro) heading for Elbgaustrasse and get off at Stellingen (Arenen). On matchdays there are then shuttle buses from there to the stadium. Total journey time is around an hour.

Full timetable and fare information can be found on the HVV regional public transport website. As far as fares go, you're covered if you have a rail pass such as Interrail (valid for trains and S-Bahn) or the Deutschlandticket. You're also covered if you have a Hamburg Card, which additionally provides discounts to various tourist attractions.

If you're planning to pick up a hire car from the airport, the better-known rental companies based there are Avis, Budget, Enterprise, Europcar, Hertz and Sixt. You can see which offer the best prices here at Rentalcars.co.uk.
