The history of Wilson Airport (WAP) dates back to the 1st world war, commercial routes were pioneered by Imperial Airways and its successor BOAC in the 1920's and in July 1929, Wilson Airways Ltd was formed by Mrs. Florrie Wilson to operate from an airfield in Nairobi, at Dagoretti Corner.
Later, that year the airfield at Dagoretti Corner was abandoned in favour of the present site of WAP, originally called Nairobi Aerodrome. The construction work was carried out by the Public Works Department and by 1933, 2 murram runways had been laid and Imperial Airways commenced operation of an airmail service to Kisumu in July of that year.
In 1962, the GOK renamed the aerodrome “Wilson Airport" as a tribute to the pioneering spirit of the real expansion of Wilson into the major domestic airport it is today, a gazetted border control point accommodating short haul scheduled domestic services, International, Private and Charter Flights.
