Cheap Flights from London to Johannesburg — $370

London is served by several airports with distinct roles: Heathrow and Gatwick act as the main international hubs handling long-haul and premium carriers, while Stansted and Luton typically cater to low-cost and charter airlines; London City is a compact business-oriented option close to the financial district. Heathrow sits about 20–25 km west of central London, Gatwick some 45 km south, Stansted and Luton roughly 55–65 km northeast and northwest respectively, and London City around 10 km east. Transfer options include the Heathrow Express (15–25 minutes, premium fare), Gatwick Express or Thameslink trains (30–40 minutes), Stansted Express (35–50 minutes), and regular rail/bus links; fares can range from budget coach prices to higher express train rates. Pros: broad airline choice and frequent services; cons: peak-time congestion and variable transfer costs depending on airport and service chosen.

Johannesburg is served primarily by OR Tambo International (JNB), the country’s main international hub and the usual choice for long-haul and regional carriers such as South African Airways and many international airlines. It typically handles most premium and connecting traffic and can be pricier than secondary options. Lanseria (HLA) operates as a smaller, budget-leaning alternative used by several low-cost and regional operators. OR Tambo sits about 20–25 km east of central Johannesburg; Gautrain express rail links the airport to Sandton and the city in roughly 15–25 minutes (fares can be moderate to mid-range), while taxis and rideshares take 25–45 minutes depending on traffic and cost varies. Lanseria is around 40 km northwest and usually requires a 45–60 minute drive or shuttle. Pros: OR Tambo offers extensive connections and amenities; cons: it can be busy and subject to peak-hour delays. Lanseria can be quicker for budget travelers but has fewer facilities and less frequent public transport.
