Here's how much your December road trip will cost in tolls and petrol compared to flying

If you want to lock down your December holiday plans, now is probably the time to start booking.

And, with the absence of low-cost airlines, driving to your holiday destination will likely be cheaper than bundling the family into a plane and renting a car on arrival.

Although fuel prices are likely to fluctuate between now and December, they're less variable and slightly more predictable than airfares, which can increase overnight by several hundred rand if the airline's secret profit-maximising algorithm changes its mind.
