RAF Northolt — Northolt, Greater London, United Kingdom

NHT is RAF Northolt, one of the oldest Royal Air Force stations still in operation, located in the London Borough of Hillingdon. Opened in 1915, Northolt played a critical role during the Battle of Britain as a fighter base and later became a key hub for VIP and government flights serving London when Heathrow is congested. NHT primarily handles business jets, diplomatic aircraft, and military transport rather than scheduled airline traffic. Its single runway sits close to residential areas, which has historically limited operating hours and passenger volume. The station also maintains ceremonial duties for the RAF and houses various defense units. For decades NHT has quietly supplemented London's aviation capacity for high-profile and private travelers.
