Johannesburg is the network gateway
O.R. Tambo usually offers the broadest onward network inside Southern Africa. It is the natural entry for Johannesburg, Pretoria, Kruger by road and many regional connections.
Cape Town can remove an entire travel day
If the first half of the trip is Cape Town, the Winelands or the Garden Route, a direct or single-connection itinerary into CPT may be worth more than a lower fare into Johannesburg.
Price the whole route
Compare bags, airport transfers, overnight stays, domestic sectors and protection between separate tickets. A slightly higher long-haul fare can still produce a cheaper and calmer holiday.
Frequently asked questions
What is the best airport to fly into for South Africa?
Johannesburg is the broadest gateway; Cape Town is best when the Cape is the first destination. The right answer follows the itinerary.
Should you book domestic flights separately?
Sometimes, but separate tickets add connection risk. Leave a generous buffer and understand that one airline may not protect a missed connection to another booking.
