With one stop, travel time often ranges from 12 to 14 hours, depending on the connection point. The return flight is often slightly shorter, averaging about 9 hours to 9 hours 30 minutes nonstop." }, "q1": { "question": "Are there any direct flights from Denver to Paris?", "answer": "Yes, Air France flies non‑stop from Denver to Paris CDG six days a week — Monday, Tuesday, Wednesday, Friday, Saturday, and Sunday — with a single daily departure at 5:40 PM. Thursday is the only day without a non‑stop flight.", "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). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours. Carrier service and weekly frequencies are summarized 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).

U.S. citizens do not need a visa for short stays in France (up to 90 days within any 180-day period) but are expected to comply with the upcoming European Travel Information and Authorisation System (ETIAS), which is anticipated to launch in 2025. French citizens traveling to the U.S. must have a valid visa unless they qualify for the Visa Waiver Program, in which case they need an approved ESTA. Other nationalities should check both French and U.S. entry rules." }, "q3": { "question": "What are the ground transportation options in Paris?", "answer": "From Paris Charles de Gaulle Airport, the RER B train is the most-used option, reaching central Paris in about 30 minutes. Taxis offer fixed fares and direct rides, while ride-share services (VTC) are also available. The RoissyBus provides a dedicated bus link to the city, and rental cars are accessible via major highways with on-airport parking. The upcoming CDG Express train will eventually cut the journey to Gare de l'Est to just 20 minutes, making it the fastest choice once it opens.", "toolsUsed": [], "references": [ { "url": "https://parisaeroport.fr/en/passengers/charles-de-gaulle-airport", "title": "Welcome to Charles-de-Gaulle airport (CDG Airport) - Paris Aéroport", "time_published": "2026-03-25T23:16:15Z" }, { "url": "https://parisaeroport.fr/en/charles-de-gaulle-airport/terminal-3", "title": "Maps & Terminals at Paris Charles de Gaulle – Paris Aéroport", "time_published": "2026-03-25T23:15:25Z" }, { "url": "https://en.wikipedia.org/wiki/CDG%20Express", "title": "CDG Express", "time_published": "2026-01-29T07:39:10Z" }, { "url": "https://en.wikipedia.org/wiki/Aéroport_Charles_de_Gaulle_2_TGV_station", "title": "Aéroport Charles de Gaulle 2 TGV station", "time_published": "2026-04-23T11:27:05Z" }, { "url": "https://www.parisaeroport.fr/en/group/strategy/airport-network/paris-charles-de-gaulle-airport", "title": "Pardon Our Interruption" } ] }, "q4": { "question": "When is the cheapest time to fly from Denver to Paris?", "answer": "The cheapest months to fly from Denver to Paris are October ($931), September ($941), and April ($947), while the most expensive are June ($1282), December ($1230), and March ($1188). The low season runs October, September, April, and November, with high season in May, March, December, and June.", "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 Paris?", "answer": "For Denver to Paris, the optimal booking window is about 7 to 10 weeks before departure, with the absolute lowest fare seen around 55 days out at $987. For summer or holiday travel, booking a few weeks earlier than the typical window can help avoid steeper price hikes, since last-minute fares can climb above $1,700.", "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 Paris?", "answer": "No nonstop red‑eye flights operate from Denver to Paris, but several one‑stop itineraries include an overnight long‑leg.

These flights all arrive in the morning hours — the next morning.", "methodology": "Red-eye flights are identified from scheduled local departure and arrival times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg.", "toolsUsed": [ "redeye_flights" ] }, "q7": { "question": "Which airlines usually operate this route from Denver to Paris?", "answer": "Air France operates the sole nonstop service from Denver to Paris, with six weekly flights on Monday, Tuesday, Wednesday, Friday, Saturday, and Sunday, departing at 5:40 PM.

These hubs minimize backtracking and provide efficient transfers through well‑organized airports. For US citizens and many nationalities, no transit visa is needed as you remain in sterile areas." }, "q9": { "question": "How reliable are on‑time departures on this route from Denver to Paris?", "answer": "On-time performance is generally reliable, though afternoon thunderstorms in Denver can cause delays.
