There is no scheduled nonstop service on this route, so the journey requires at least one connection; a typical one-stop itinerary takes roughly 21 to 26 hours in total, depending on the layover.", "methodology": "Carrier service, flight times and distances for this route come from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).

The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation.

Metered taxis are available at an accredited taxi terminus behind the hotels and are a reliable door-to-door option, often used by visitors unfamiliar with the area.

The most expensive months are July, June, and December, where average fares climb to $2,112, $2,019, and $2,001.", "methodology": "This 'good deal' estimate shows a representative best price for each departure date across roughly a 12-month window (about 3 months back and 9 months forward). It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Denver to Johannesburg?", "answer": "For flights from Denver to Johannesburg, the optimal booking window is roughly 5 to 8 weeks before departure, with average fares around $1,680. The absolute lowest fares appear around 40 days out at about $1,668. Booking last-minute can be significantly more expensive, with prices climbing above $2,100, while booking more than 5 months ahead also tends to be pricier. For summer or holiday travel, it's wise to book at the earlier end of that window or even slightly sooner, as demand can push fares higher.", "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row.", "toolsUsed": ["booking_timing"]}, "q6": {"question": "Are overnight (red‑eye) flights available from Denver to Johannesburg?", "answer": "Overnight red‑eye connections are available from Denver to Johannesburg, with the long leg departing Europe in the late evening.
