Due to the current Covid-19 pandemic, all regular services and hours may be subject to change. Thus, if the idea is to spend the night in the public area, consider a plan B in case the stay inside the airport is only allowed for those who are close to boarding.
Spending the night at the airport
Prague airport is comprised of two main terminals, but it is small and easy to navigate. Have your ticket ready in case the security personnel asks for it. Lights remain on and the place can become quite cold, so it is recommended to have a mask, blankets or a sleeping bag.
Where to rest: Throughout the enclosure, you can find many seats, but most have armrests. On the first floor of Terminal 2, between concourses C and D, there is a rest area that is pretty quiet and has comfortable couches. Another option (by paying or with a credit card that provides the service) is to use one of the VIP lounges, where you can access more amenities and privacy. The only problem is that they close at night. On the other hand, there is accommodation in Terminal 1, while in the vicinity of the airport grounds there are several hotels.
Baggage: There is a left-luggage service in Terminal 2, but it is temporarily unavailable.
Eating and drinking: Inside both terminals, you can find options that remain open during the night.
Restrooms: Free showers in Pier D, on the third floor.
Wi-Fi: Free and unlimited.
Other services available around the clock: ATMs, duty-free store, prayer room, children's playgrounds, baby changing facilities.
In Terminal 1, you can find the AeroRooms hotel, which you can access through the Departures Hall or from the building connecting both terminals. Besides that, you can find many accommodations nearby, among them:
Courtyard by Marriott Prague Airport (0.2 km/0.1 miles)
Holiday Inn Prague Airport (0.7 km/0.4 miles)
Penzion V Mastali (1.3 km/0.8 miles)
