Airport overview
Who should use SIS?

Sishen is a mining rotation route, and it ignores every normal fare rule
Sishen Airport serves the iron-ore mining corridor around Kathu in the Northern Cape. Its traffic is not business travel in the general sense and it is certainly not leisure — it is workforce and specialist movement tied to mining operations, which produces a demand pattern unlike anything else in the domestic network.
Mining rotations do not follow a Monday-to-Friday week. They follow shift cycles, and those cycles concentrate demand onto specific changeover days that repeat on their own schedule. The result is that a route with very few daily options can be effectively full on one day and quiet on the next, for reasons no seasonal or day-of-week rule of thumb will predict.
There is also no meaningful road fallback. The Northern Cape distances involved mean that driving from Johannesburg is a serious undertaking rather than a casual alternative, which removes the pricing ceiling that keeps some short inland routes honest. Combined with minimal frequency, that makes Sishen one of the least flexible routes in the country.
Practical consequence: on this route, schedule certainty is worth more than headline fare. Check the fare conditions and the cost of changing before you book, because if your plans move, the next available seat may be a rotation cycle away rather than a few hours.

Total-trip decision
The airport choice can change the real price.
Do not compare airfare in isolation. Add the road transfer, parking, car-hire days, tolls and the value of your time. A regional airport with a higher ticket can still produce the cheaper trip.
Also check the exact airport code on the itinerary. City names can hide different airports, and Johannesburg in particular requires care because O.R. Tambo and Lanseria are separate.
