Secunda Airport — Secunda, South Africa

Secunda Airport, coded ZEC, is located in Secunda, a South African industrial city in Mpumalanga province built around Sasol's massive synthetic fuel production complex. The airport primarily serves business travelers, engineers, and executives connected to Sasol's coal-to-liquid fuel operations, one of the largest facilities of its kind in the world. ZEC supports charter flights and general aviation rather than large-scale commercial airline service, reflecting Secunda's status as a company town built specifically to house the workforce driving South Africa's synthetic fuel industry. The airport remains an important logistical asset for corporate and industrial travel in the Mpumalanga region.
