Bus 100E — direct to the centre
The 100E airport shuttle runs roughly every 20 minutes direct to Deák Ferenc tér in central Pest, stopping at Kálvin tér on the way. The ride takes 30–40 minutes and a ticket costs around 2,200 HUF.
You need the dedicated 100E ticket — standard BKK singles and travelcards are not valid. Buy it at the purple BKK machine at the bus stop outside Terminal 2, or in the BudapestGO app before you board.
Rock-bottom alternative: Bus 200E to Kőbánya-Kispest (regular BKK ticket, ~450 HUF), then metro M3 into town. Slower and a transfer, but the cheapest way in.
