Yes, planes can land at London Gatwick (LGW) at night, but they are subject to strict noise restrictions and flight quotas. The "night period" is generally defined as 23:00 to 07:00, during which the airport operates under a "night quota" system regulated by the UK Department for Transport. For the 2026 season, Gatwick is permitted a maximum of approximately 11,200 night movements annually. Aircraft are assigned a "Quota Count" (QC) based on their noise levels; quieter, modern planes like the Airbus A321neo or Boeing 787 have low QC ratings, while older, noisier jets are often banned entirely between 23:30 and 06:00. This system encourages airlines to use their quietest fleet for late-night arrivals and departures. While residents in the surrounding Sussex area often campaign for a total ban, the airport remains a 24-hour facility to accommodate long-haul international schedules and low-cost carrier rotations, provided they stay within the government-mandated noise limits.
