Yes, you can sleep overnight at Gatwick Airport in 2026, as both the North and South Terminals are open 24 hours a day. While it is a common practice for travelers with early morning flights, the experience varies by terminal. The South Terminal is generally considered more "sleep-friendly" because it has wider benches and more 24-hour services, such as the Tesco Express. Security staff typically patrol between 1:00 AM and 4:00 AM and may ask to see your boarding pass to ensure you are a legitimate traveler. For a much more comfortable rest, the YOTELAIR (located in the South Terminal public area) offers "capsule" cabins that can be booked in 4-hour blocks or for a full night, providing a private bed and shower. If you prefer a traditional hotel, the Bloc Hotel (South Terminal) and Premier Inn (North Terminal) are both located within the airport complex. For those on a budget sleeping in the terminal, it is recommended to bring an eye mask, earplugs, and a light blanket, as the terminals are well-lit and can become quite chilly due to the air conditioning systems throughout the night.
