London Gatwick (LGW) does operate 24 hours a day in 2026, but it is subject to strict Night Flight Restrictions to minimize noise for local residents. Between 11:30 PM and 6:00 AM, the airport is governed by a "Night Quota" system, which limits both the total number of flights and the amount of noise they can produce. Airlines are generally prohibited from scheduling "high-noise" aircraft during these hours, favoring modern, quieter jets like the Airbus A321neo or Boeing 787. In 2026, Gatwick is permitted roughly 11,200 night movements per year, with the majority occurring during the peak summer season to accommodate holiday charters. While you will see arrivals and departures throughout the night, the frequency is significantly lower than during the day. For 2026 travelers, this means early-morning "red-eye" arrivals from the U.S. or late-night departures to the Mediterranean are common, but the airport remains much "quieter" during the deep midnight hours.
