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
Beijing airport is a huge place, with a large number of passengers throughout the day, and even at night. Therefore, have earplugs or headphones ready. In addition, the air conditioning is usually strong, so pack warm clothes.
Where to rest: Terminal 3 is the most comfortable place, as it has plenty of seating, although mostly made of wood. The ones that are padded have armrests. Eateries on the mezzanine floor, in particular, have very comfortable benches. Another option (by paying or through different memberships or credit cards providing the service) is to use one of the VIP lounges, although these close at night. For a better rest, there are private cabins in terminals 2 and 3, in addition to several hotels in the vicinity.
Baggage: Several offices around the airport handle the left luggage service, so you will be able to forget about your bags until check-in hours.
Eating and drinking: There are numerous eateries inside the three terminals that remain open during the night.
Restrooms: Showers available inside the VIP lounges.
Wi-Fi: Free and unlimited.
Other services available around the clock: ATMs, currency exchange bureaus, children's play areas, baby care rooms.
Inside terminals 2 and 3 (gates 10 and 11, 38, E19 and E27), there are private cabins from GoSleep, which can be used for up to 1 hour. You can find numerous accommodations in the vicinity of the airport. Some of them have shuttle services for their guests.
