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
Washington National Airport operates with numerous flights and connections, so there is usually constant movement, even through the night. Although terminals are open 24 hours a day, passengers wishing to spend the night inside the enclosure will have to remain in the public area once the security control closes. As the place is pretty cold and noisy, it is recommended to have a sleeping bag, blankets, earplugs or headphones.
Where to rest: In general, it is not a very comfortable airport for resting and seats have armrests. However, in the chapel, you can find some padded benches. You can also lay on the floor close to the heaters, by the windows. Another option is to enter one of the VIP lounges, where you can get access to more amenities and privacy, although they close at night. Finally, several accommodations in the vicinity offer shuttle services.
Baggage: There are no left-luggage offices, so you will have to keep your baggage with you until check-in.
Eating and drinking: Most of the available options are open between 7:00 am and 10:00 pm, but there are vending machines inside both terminals.
Wi-Fi: It is free and unlimited.
Other services available around the clock: ATMs, chapel, nursing rooms.
Although there are no hotels on-site, several accommodations in the vicinity provide free transportation to and from the airport. In the baggage reclaim areas, there are courtesy phones to request information and make reservations.
