Most flights to regional airports in South Africa go through JNB, but there are a few things to do during a layover. Head to any observation deck and watch planes as they come and go, or grab a meal at one of several restaurants at the airport. You can also access some of the lounges by paying a single fee or go shopping at the airport’s duty-free shops. If your layover is more than 7h, head into town for a bit of exploration.
