With one stop, depending on the layover city like Chicago or New York, total travel time often ranges from 11 to 13 hours. The return flight from Paris to Denver is usually about 10 hours 15 minutes due to prevailing winds." }, "q1": { "question": "Are there any direct flights from Denver to Paris?", "answer": "Yes, Air France flies nonstop from Denver to Paris (CDG) six days a week — Monday, Tuesday, Wednesday, Friday, Saturday, and Sunday — with a single daily departure around 5:40 PM. It's the only airline offering a direct flight on this route.", "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). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.", "toolsUsed": [ "route_airlines", "flight_schedule" ] }, "q2": { "question": "Are there visa requirements to travel from Denver to Paris?", "answer": "Yes, visa requirements apply for travel between Denver and Paris. U.S. citizens can visit France for up to 90 days without a visa, but must have a passport valid for at least three months beyond their intended stay. From mid-2025, U.S. citizens will also need an ETIAS authorization before travel. French citizens can travel to the U.S. under the Visa Waiver Program with a valid ESTA authorization. Other nationalities should check both U.S. and French entry requirements based on their citizenship." }, "q3": { "question": "What are the ground transportation options in Paris?", "answer": "From Charles de Gaulle Airport, the RER B train is the most-used link to central Paris, reaching Gare du Nord in about 30 minutes. Taxis offer a fixed-fare, door-to-door ride, while VTC services like Uber provide similar direct options. Bus 9517 (formerly RoissyBus) connects to Saint-Denis Pleyel on metro line 14, and other buses and shuttles serve the region. The fastest option will soon be the CDG Express train, a dedicated 20-minute service to Gare de l'Est opening in March 2027.", "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, September, and April, with average fares around $930 to $950. The most expensive months are June, December, and March, where average prices climb to roughly $1,190–$1,280.", "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 the best fare from Denver to Paris, book 7 to 10 weeks before departure, when fares average around $996. The lowest price in the data is $987 at 55 days out, and last-minute bookings (0 days) jump to $1,769. This window is typical for shoulder seasons; for summer and holidays, aim for the earlier end or even slightly sooner, as peak demand can push optimal booking to 10–12 weeks out.", "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 overnight (red-eye) flights are available from Denver to Paris — neither nonstop nor connecting itineraries with a red-eye long leg were found in the schedule.", "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 only nonstop flights from Denver to Paris, with six weekly flights on a seasonal schedule from Denver (DEN) to Paris Charles de Gaulle (CDG).

These hubs offer frequent connections, efficient transfers, and for Reykjavik, visa-free transit for eligible nationalities, keeping total travel time competitive." }, "q9": { "question": "How reliable are on‑time departures on this route from Denver to Paris?", "answer": "On-time departures are generally reliable, though afternoon thunderstorms in Denver can cause delays. Early flights, particularly on United, tend to have better punctuality." }, "q10": { "question": "Which months have the best weather for traveling to Paris?", "answer": "April to June and September to October offer pleasant temperatures, blooming or autumn scenery, and fewer tourists than summer." }, "q11": { "question": "What documents should I bring with me to the airport when flying from Denver to Paris?", "answer": "Bring a passport valid for at least three months beyond your planned departure from France, proof of onward or return travel, and a payment method for baggage. U.S. citizens can visit visa-free for up to 90 days, but starting in 2025, an ETIAS authorization will be required. Check for any vaccination certificate requirements." }, "q12": { "question": "Which airport should I use in Paris?", "answer": "Charles de Gaulle is the main international hub for full-service carriers and long-haul flights. Orly is closer to central Paris and focuses on domestic and European routes, often with low-cost options. Beauvais is far from the city and primarily serves ultra-low-cost carriers." }, "q13": { "question": "How do I get to Denver Intl Airport from the city center?", "answer": "The fastest and most popular way to reach Denver International Airport from downtown is the RTD A‑Line commuter train, which runs every 15–30 minutes from Denver Union Station directly to the airport transit center in about 37 minutes. Ride‑share services like Uber and Lyft, taxis, and shared‑van shuttles also provide door‑to‑door convenience at a higher cost, while driving yourself and parking at the airport is straightforward with several on‑site lots and garages.
