Neither route is practical by car. Flying is the recommended transport for both.
Nairobi (Kenya) has a population of 4,734,000 and is located in the Nairobi region of Africa. It's a significant city with good transport links and cultural offerings.
Johannesburg (South Africa) has a population of 5,635,127 and is situated in Gauteng, Africa. This major global city has multiple airports and world-class infrastructure.
Choose this route if your priority is reaching Nairobi (Kenya) — a city of 4,734,000 in the Nairobi region of Africa. It is also the shorter option at 3,553 km, which translates to a 3h 36min flight-time saving and roughly 731 kg less CO₂ per passenger versus the alternative. This is a fly-only route in practice — overland travel is not realistic at 3,553 km. The initial bearing is 217° (SW), so a great-circle flight leaves Dubai heading roughly SW.
This route is the right call if you are heading to Johannesburg (South Africa) — a city of 5,635,127 in the Gauteng region of Africa. Even though it is the longer route at 6,420 km, it remains the obvious pick when Johannesburg is the actual destination, when departure schedules from Dubai are more convenient, or when fares undercut the alternative. Overland travel is not practical for 6,420 km; flying is the realistic mode. Departing Dubai, the great-circle bearing toward Johannesburg is 209° (SSW).

All distances on SnapDistance are calculated using the Haversine formula, which determines the great-circle distance between two points on Earth's surface. This gives the shortest possible distance over the globe, which is the measurement used for aviation and navigation. Actual travel distances by road or rail are typically 20-40% longer due to terrain, borders, and infrastructure routing. Flight times assume 800 km/h cruising speed with 30 minutes for takeoff and landing. Driving estimates use 80 km/h average speed with a 30% road distance factor.
