On the return leg, the median scheduled time is 4 hours 0 minutes, a slight increase due to prevailing winds.", "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.", "toolsUsed": ["flight_schedule"]}, "q3": {"question": "What are the ground transportation options in Mexico City?", "answer": "From Benito Juárez International Airport, the most-used option is the Metrobús Line 4, a bus rapid transit route that runs daily to downtown for $30 MXN (about $1.50 USD) and takes 30–45 minutes, though it can be crowded. Rideshares like Uber and Didi are widely available and often the fastest and most comfortable, with fares around $150–300 MXN. Authorized airport taxis offer fixed rates and are a safe, direct alternative for about $200–400 MXN. Car rentals are present but generally not recommended for city-center trips due to heavy traffic and limited parking. The airport is not directly connected to the Metro system, so mass transit beyond the Metrobús requires a transfer.", "toolsUsed": [], "references": [{"url": "https://en.wikipedia.org/wiki/Transportation_in_Mexico_City", "title": "Transportation in Mexico City", "time_published": "2026-06-17T23:44:52Z"}, {"url": "https://en.wikipedia.org/wiki/Mexico%20City%20International%20Airport", "title": "Mexico City International Airport", "time_published": "2026-04-28T12:29:12Z"}, {"url": "https://www.aicm.com.mx/en/passengers/services/service-providers/transportation/metrobus", "title": "Metrobus | Aeropuerto Internacional de la Ciudad de México", "time_published": "2025-06-04T21:48:43Z"}, {"url": "https://www.aicm.com.mx/en/passengers/services/service-providers/transportation/buses", "title": "Buses | Aeropuerto Internacional de la Ciudad de México", "time_published": "2024-11-13T05:59:53Z"}, {"url": "https://en.wikipedia.org/wiki/Transportation%20in%20Mexico%20City", "title": "Transportation in Mexico City", "time_published": "2026-04-26T16:50:05Z"}]}, "q4": {"question": "When is the cheapest time to fly from Denver to Mexico City?", "answer": "The cheapest months to fly from Denver to Mexico City are May, June, and September, with average fares around $437–$445. The most expensive months are December, March, and January, with averages climbing to $537–$644.", "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 Mexico City?", "answer": "For flights from Denver to Mexico City, the optimal booking window is roughly 7 to 10 weeks before departure, with average fares around $443. Booking around 60 days out can yield the lowest price, around $440, while last-minute tickets can climb above $580. During peak summer or holiday periods, demand may push the best window slightly earlier, so aiming for 10 to 12 weeks ahead can help secure a better deal.", "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 Mexico City?", "answer": "No nonstop red-eye flights operate from Denver to Mexico City.

Another departs Denver on United, connects at San Francisco (SFO), and the overnight leg on United departs SFO at 22:41 and arrives Mexico City at 04:00 in the early hours.", "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 Mexico City?", "answer": "Aeromexico, United, and Volaris all operate nonstop flights from Denver to Mexico City.
