        "question": "What is the typical flight duration from Cancún to Washington D.C.?",
        "answer": "A nonstop flight from Cancún (CUN) to Washington Dulles (IAD) typically takes about 3 hours 30 minutes to 3 hours 45 minutes. With a layover, common connecting cities like Atlanta (ATL) or Charlotte (CLT) result in total travel times of 5 to 7 hours. The return flight from Washington D.C. to Cancún is usually similar in duration."

      "q1": {
        "question": "Are there any direct flights from Cancún to Washington D.C.?",
        "answer": "Yes, United Airlines operates daily nonstop flights from Cancún (CUN) to Washington Dulles (IAD), with multiple departures throughout the day ranging from early morning to late afternoon. United is the only carrier shown in the schedule data offering direct service on this route, with roughly 8 flights per day spread across all seven days of the week.",
        "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. 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.",

        "question": "Are there visa requirements to travel from Cancún to Washington D.C.?",
        "answer": "Yes — visa requirements apply for travel from Cancún to Washington D.C. depending on your nationality. If you are a U.S. citizen, you do not need a visa to enter the U.S. If you are a Mexican citizen, you generally need a valid U.S. visa or an approved ESTA under the Visa Waiver Program if eligible, but Mexico is not currently a VWP country, so a visa is typically required. Other nationalities should check U.S. entry rules. There are no exit visa requirements from Mexico for any nationality."

        "question": "What are the ground transportation options in Washington D.C.?",
        "answer": "Washington D.C. is served by three major airports: Dulles International (IAD), Ronald Reagan National (DCA), and Baltimore/Washington International (BWI). From Dulles, the Silver Line Metro is the most used and cost-effective option, reaching downtown in about 45–50 minutes. Taxis and ride-shares cost $50–$70 and often take longer due to traffic. Car rentals are available but parking in D.C. is difficult and expensive. From Reagan National, the Yellow and Blue Metro lines provide a quick 15–20 minute ride to central D.C., making Metro the top choice. Taxis and ride-shares are also convenient but pricier. From BWI, the MARC train connects to Union Station in about 40 minutes, and Amtrak offers a similar service. The airport shuttle bus to the Greenbelt Metro station is a slower alternative. Taxis and ride-shares from BWI to D.C. can exceed $100. Overall, the Metro is the most popular and practical option for reaching downtown from Dulles and Reagan National."

        "question": "When is the cheapest time to fly from Cancún to Washington D.C.?",
        "answer": "The cheapest months to fly from Cancún to Washington D.C. are September (around $355), August (around $362), and July (around $384), while the most expensive are December (around $570) and March (around $457).",
        "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.",

        "question": "How far in advance should I book tickets from Cancún to Washington D.C.?",
        "answer": "For Cancún to Washington D.C., the best fares are typically found when booking 9 to 12 weeks before departure, with an average price around $461. The very lowest fare observed was $457 at 85 days out, while last-minute tickets can cost over $600.",
        "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. 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.",

        "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.",
