You can choose from several options. Which one you choose is entirely up to you. In any case, make sure to allow enough time for entry to the venue. The airport gates open at 8 AM on both days.

I want to arrive by public transport bus.
You can take the regular city transport from the main train station (ČD) using lines 88, 8, 23, and 24 to the "K letišti" stop. The public transport company will reinforce these lines with additional services on both days.
The timetable for the additional services will be published during May.

 Po příjezdu na hlavní nádraží ČD máte dvě možnosti:
1)  Před budovou ČD nasednete do autobusů MHD a běžnými linkami 88, 8, 23, 24 nebo posilovacími spoji vystoupíte na  zastávce K letišti.  Dále projdete hlavní vojenskou bránou do areálu letiště.
2) Na hlavním nádraží přesednete do osobního vlaku – směr Chrudim a vystoupíte na vlakové zastávce Pardubice – závodiště. Dále budete pokračovat pěšky východní bránou do areálu letiště.

Upon arrival at the main train station (ČD), you have two options:

1) In front of the ČD building, take the public transport buses on regular lines 88, 8, 23, 24, or the additional services, and get off at the "K letišti" stop. Then, proceed through the main military gate into the airport grounds.
2) At the main station, transfer to a passenger train heading towards Chrudim and get off at the "Pardubice – závodiště" train stop. Then, continue on foot through the eastern gate to the airport grounds.

Payment by card is not possible. You can park at the racetrack or in the area of the international airport EBA. Please follow the traffic signs and drive along the yellow route.

If coming from the direction of Přelouč, you can turn right (onto the "old" Pražská street) and continue right again towards the international airport EBA to the designated parking lot, where you will enter the airport grounds through the western pedestrian gate.
If coming from the direction of Přelouč, you can continue along Pražská street and then turn right into the racetrack area through the so-called paddock gate and walk into the airport grounds through the main military gate.
