Spending the night at the airport
If you have an early morning flight or a connecting flight with a long layover, the London Heathrow airport offers facilities that make it possible for you to stay overnight without having to book for a hotel outside the grounds. All terminals remain open 24 hours a day and are connected to each other by buses.
Where to rest: In Terminal 2 there are numerous comfortable seats, but even late at night it is very bright and noisy, so it is advisable to have an eye-mask and earplugs. In the boarding area of Terminal 3 you can find lounge chairs, but keep in mind that the security staff can ask you to move. As for Terminal 4, the public area has more comfortable options for spending the night. There is even a café that opens around the clock where you can stay if you buy something. For Terminal 5, benches without armrests are available on the second floor. If you want to take a shower or be in a more private and comfortable area, all terminals have VIP lounges. The only problem is they close at night. SEE VIP LOUNGES For uninterrupted sleep, there are hotels in terminals 4 and 5 and several alternatives in the vicinity.
Baggage: All terminals have left-luggage services, but they work from 5:00 am to 11:00 pm. Therefore, if your flight leaves very early in the morning, you will probably have to spend the night with your bags.
Eating and drinking: There are coffee shops open 24 hours a day in terminals 2, 4 and 5.
Restrooms: Showers are available in many of the VIP lounges.
Wi-Fi: The airport has free and unlimited access. There are also AC power plugs and USB ports to recharge mobile devices.
