News sites publish fly-vs-drive comparisons once or twice a year, pinned to that month's petrol price. The problem: South African fuel prices change on the first Wednesday of every month, and 2026 has been the most volatile fuel year in history — from a near four-year low of R20.75/litre in January to a record R28.06/litre in June, with the remaining fuel levy relief expiring on 1 July. A comparison written in April is fiction by June.
Airfares move even faster. A Johannesburg–Cape Town seat booked six weeks out can cost less than half the same seat booked six days out. That's why a static article can't answer this question — and a calculator can.
The costs people forget on each side
Hidden costs of flying
- Airport transfers: an Uber from Sandton to OR Tambo plus King Shaka to the Durban beachfront runs roughly R450–R500 each way for the pair of trips — nearly R1,000 on a return trip.
- Airport parking: if you drive yourself, OR Tambo long-stay parking is around R1,000 for a week.
- Checked baggage: low-cost carriers price bags separately. See our SA baggage rules guide before assuming your fare includes a bag.
- Car hire at the destination: if you need wheels in Cape Town anyway, that's a flying-side cost. Compare via our car hire page.
Hidden costs of driving
- Tolls: the N3 to Durban has five mainline plazas (De Hoek, Wilge, Tugela, Mooi River, Mariannhill) totalling roughly R260–R290 one way for a Class 1 vehicle at 2026 tariffs.
- Wear and tear: AA rates put true running cost well above fuel-only cost — tyres, services and depreciation are real money on a 2,800km Cape Town round trip.
- Overnight stops: most families break the 14–15 hour Joburg–Cape Town drive in Colesberg or Bloemfontein. Add the room.
- Your time: a Durban drive is 6–7 hours door to door; the flight is about 70 minutes plus airport time. Two extra leave days have a value too.

Frequently asked questions
Is it cheaper to fly or drive from Johannesburg to Durban?
For one or two people, flying usually wins once you count fuel (±R1,300–R1,500 one way at R28.06/litre) plus ±R265 in N3 tolls each way. For three or more sharing a car, driving usually wins — the car costs the same whether it carries one person or five.
Is it cheaper to fly or drive from Johannesburg to Cape Town?
Flying, almost always, for small groups. The 1,400km drive burns roughly R3,000+ in fuel one way at current prices, before tolls and an overnight stop. An early-booked low-cost fare frequently beats the fuel bill alone.
How much are N3 tolls to Durban?
Roughly R260–R290 one way for a Class 1 light vehicle across the five mainline plazas at 2026 tariffs. Tariffs adjust every March — check N3TC's current rates before you travel.
What petrol price does the calculator use?
It defaults to R28.06/litre — the record inland 95 price from 3 June 2026 — but the field is editable, so update it to the pump price in your month of travel.
When does driving clearly beat flying?
Travelling 3+ in one car, needing your car at the destination, carrying surf boards/bikes/baby gear, or travelling at peak season when airfares spike. Flying clearly wins for solo travellers on any route over 900km.
