London Gatwick (LGW) operates 24 hours a day, but it is subject to strict Night Flight Restrictions in 2026 to mitigate noise pollution for surrounding communities. During the "Night Quota Period" (typically 11:30 PM to 6:00 AM), the airport uses a "quota count" (QC) system. Each aircraft is assigned points based on its noise level; quieter, modern planes like the Boeing 787 or Airbus A321neo use fewer points, allowing more of them to fly at night. While you will see late-night departures for long-haul routes or delayed European holiday flights, the airport has a seasonal "cap" on the total number of night movements. If an airline exceeds its quota or uses a "noisy" older aircraft late at night, they face significant financial penalties, making 2:00 AM departures rare except for emergency situations or specific high-efficiency seasonal charters.
