As of 2026, London Gatwick Airport generally recommends arriving at least two hours before a short-haul or domestic flight and at least three hours before a long-haul flight. If you are traveling during peak periods—such as school holidays, summer weekends, or early Monday mornings—adding an extra hour is highly advisable to account for potential queues at bag drop and security. For those flying to the U.S., some airlines suggest arriving four hours early due to additional security screening requirements. To save time, utilize online check-in and self-service bag drop kiosks if your airline offers them. Gatwick also features a "Premium Security" option for a fee, which can significantly speed up the process. Always check your specific airline’s guidance on your boarding pass, as gate closure times are strictly enforced, usually 20 to 30 minutes before departure, and the walk to certain gates in the North or South terminals can take up to 15-20 minutes.
