Budapest’s transit system (BKK) combines historic transport like Metro Line 1 (the oldest electric underground railway on the European continent, built in 1896) with cutting-edge mobile payments.

The BudapestGO App

Download the official BudapestGO app before arrival. It allows you to plan routes, purchase single tickets (450 HUF / ~€1.15), 10-piece ticket booklets, or 24-hour travel cards directly on your phone.

  • Scanning QR Codes: When boarding buses and trams or entering metro stations with a digital ticket, scan the printed QR code stickers near the doors or turnstiles using your camera inside the BudapestGO app to validate the journey.

The Airport Transit Trap: 100E vs 200E

  • Bus 100E (Airport Express): Direct non-stop shuttle from Budapest Airport to Deák Ferenc tér in the city center (35 minutes). Requires a dedicated special airport ticket costing 2,200 HUF (~€5.60); standard transit passes are not valid.
  • Bus 200E + Metro Line M3 (The Budget Hack): Take regular city bus 200E to the Kőbánya-Kispest terminal station and transfer to Metro Line M3 directly into the center. Uses standard transit tickets (450 HUF / ~€1.15) and is 100% covered by 24-hour and 72-hour transit passes.
