The return westbound flight is usually 3 hours 45 minutes to 4 hours 15 minutes due to prevailing winds. With a layover, total travel time often ranges from 5 to 7 hours depending on the connection city." }, "q1": { "question": "Are there any direct flights from Denver to Washington?", "answer": "Yes, there are direct non-stop flights from Denver to Washington. United and Southwest fly non-stop to Dulles (IAD), with 105 and 76 weekly flights respectively, both operating daily, while Frontier and United also serve Reagan National (DCA) daily with 21 and 7 weekly flights. In total, over 200 non-stop flights run each week across the three carriers on both Washington airports.", "methodology": "Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).

Taxis are readily available at curbside, and ride‑share services like Uber and Lyft offer convenient door‑to‑door service.

The most expensive months are October, November, and June, where average fares climb to roughly $488, $474, and $454.", "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 Washington?", "answer": "For the best fares from Denver to Washington, book 3 to 6 weeks ahead, with the absolute lowest prices around 35 days out at about $183. During peak summer and holidays, demand pushes prices higher, so aim for the earlier side of that window or even 6 to 8 weeks in advance to avoid steep last-minute spikes.", "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 Washington?", "answer": "Yes, red-eye flights are available from Denver to Washington.
