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.

I want to arrive by train.
 

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.
 
Czech Railways offers the option to use the VLAK + Aviatická pouť discount. Pre-sale starts on May 15. This is a 25% discount on the return ticket price (i.e., from Pardubice). QR code stands will be placed at the AP venue on access paths, near the military and eastern gates, and near the CLV or VIP entrance area. More details here..

I want to arrive by car.

Parking spaces for visitors should have sufficient capacity. The parking fees are 200 CZK for a passenger car, 100 CZK for a motorcycle, and 500 CZK for a bus. Parking can only be paid in cash. 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.

When exiting from Pražská street from the city center, take the exit from the overpass into the racetrack area. After leaving the racetrack, you can purchase tickets and then walk through the eastern gate into the airport grounds.
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.

I want to go on foot.
You can enter the venue through the following gates:
