No, London Gatwick Airport (LGW) does not shut overnight; it is a 24-hour operation. However, there is a major catch for 2026 travelers: while the North and South terminals remain open "landside" (before security), the security checkpoints and "airside" shops/lounges typically close between 1:00 AM and 4:00 AM. If you have an early flight, you can stay in the landside terminal, which has padded seating and 24-hour restrooms, but you won't be able to enter the departure lounge until security reopens in the early morning. For a more comfortable experience, Gatwick features "capsule" hotels like YOTELAIR and the BLOC Hotel directly inside the terminals, which can be booked in 4-hour blocks. Thousands of passengers spend the night at Gatwick every month to save on accommodation or to catch the first "low-cost" flights to Europe, making it a very common and safe "airport camping" destination.
