So, when should you book flights in South Africa?
There is no single perfect day that guarantees the cheapest flight every time. Flight prices depend on route demand, seasonality, airline schedules, seat availability, baggage rules and how flexible your travel dates are.
As a practical rule, compare flights earlier when travelling during school holidays, December, Easter, long weekends or major event periods. For normal domestic trips, flexibility with dates and times can be just as important as booking early.
