The flight is scheduled for about 10 hours 15 minutes eastbound; on the return the typical block time is roughly 9 hours 30 minutes. No other airline currently operates a non‑stop on this route.", "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). We report the days of the week and the departure times each carrier operates. 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. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold. 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.", "toolsUsed": ["flight_schedule", "route_airlines"]}, "q3": {"question": "What are the ground transportation options in Denver?", "answer": "Denver International Airport offers a range of ground transportation options. The RTD A Line commuter train provides the fastest and most-used connection to downtown, reaching Denver Union Station in about 37 minutes. Taxis, rideshares like Uber and Lyft, and rental cars are also readily available on Level 5 of the terminal. Regional buses and shared shuttles serve broader destinations, while a free automated people mover links the terminal to concourses.", "toolsUsed": [], "references": [{"url": "https://www.flydenver.com/parking-and-transportation/to-and-from/airport-transit-center/", "title": "Airport Transit Center | Denver International Airport", "time_published": "2026-02-24T17:09:34Z"}, {"url": "https://flydenver.com/connections/", "title": "Connections | Denver International Airport", "favicon": "https://flydenver.com/apple-touch-icon.png", "time_published": "2023-09-14T15:33:21Z"}, {"url": "https://en.wikipedia.org/wiki/Automated_Guideway_Transit_System_(Denver_International_Airport)", "title": "Automated Guideway Transit System (Denver International Airport)", "time_published": "2026-06-01T08:54:40Z"}, {"url": "https://en.wikipedia.org/wiki/Denver%20International%20Airport", "title": "Denver International Airport", "time_published": "2026-04-30T15:08:23Z"}, {"url": "https://www.faa.gov/?action=searchForAirport&airportcode=PSR", "title": "Federal Aviation Administration", "favicon": "https://www.faa.gov/themes/custom/faa/favicon.png", "time_published": "2026-07-17T12:00:00Z"}]}, "q4": {"question": "When is the cheapest time to fly from Paris to Denver?", "answer": "The cheapest months to fly from Paris to Denver are October, September, and April, with average fares around $908, $922, and $947 respectively. The most expensive months are June, May, and December, where average fares climb to roughly $1,283, $1,183, and $1,179.", "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. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Paris to Denver?", "answer": "For the best fares from Paris to Denver, aim to book 8 to 11 weeks ahead, with the lowest prices around 55 days out at about $989. Summer and holiday periods push prices up, so booking earlier within that window helps lock in a better rate.", "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.

Bus 9517 (formerly RoissyBus) offers a dedicated coach service from Saint-Denis Pleyel (metro line 14), while taxis and ride‑share services provide door‑to‑terminal convenience with fixed fares from the city. Driving is straightforward via the A1 or A3 motorways, and the airport has ample short‑ and long‑stay parking that can be booked online for discounts.
