        "question": "What is the typical flight duration from Denver to Columbus?",
        "answer": "A nonstop flight from Denver (DEN) to Columbus (CMH) typically takes about 2 hours 30–40 minutes. With one stop, total travel time often ranges from 4 to 6 hours depending on the layover city. Southwest and United are the main carriers offering nonstop service on this route."
      },
      "q1": {
        "question": "Are there any direct flights from Denver to Columbus?",
        "answer": "Yes, three airlines fly non‑stop from Denver to Columbus: Southwest runs up to 84 weekly flights daily, United has four daily flights, and Frontier offers three flights on Mondays, Thursdays, Fridays, and Sundays. Together they provide non‑stop service every day 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. 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).

        "answer": "From John Glenn Columbus International Airport (CMH), you can reach downtown Columbus in about 25 minutes via the COTA AirConnect bus, which departs every 30 minutes and costs $2.75, making it the most affordable and commonly used public transit option. Taxis are available 24/7 at the ground transportation area, with a metered fare to downtown of roughly $25, offering a direct and fast alternative. Ride-sharing services like Uber and Lyft also pick up on the ground transportation level, providing convenient door-to-door service. Car rentals from agencies like Alamo are available in the parking garage for those preferring to drive. The bus is the most-used budget option, while taxis or rideshares are the fastest door-to-door choices.",

        "question": "When is the cheapest time to fly from Denver to Columbus?",
        "answer": "The cheapest time to fly from Denver to Columbus is in April, with average fares around $284, followed by March at $338. The most expensive months are September, June, and July, with average prices between $446 and $459.",
        "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.",

      "q5": {
        "question": "How far in advance should I book tickets from Denver to Columbus?",
        "answer": "For Denver to Columbus, the best fares typically appear when booking 2 to 5 weeks ahead, averaging around $252. During summer and holiday periods, it's wise to book closer to the early side of that window or even a bit earlier, as last-minute prices can spike above $400.",
        "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.",

        "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.",

Typical per‑carrier fares are not available for this route.",

      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Denver to Columbus?",

      },
      "q13": {
        "question": "How do I get to Denver Intl Airport from the city center?",
        "answer": "To reach Denver International Airport from downtown Denver, the fastest and most popular option is the RTD A-Line commuter train, which runs from Denver Union Station to the airport transit center in about 37 minutes. Ride-share services like Uber and Lyft, as well as taxis, offer door-to-door convenience with a typical drive of 35–45 minutes depending on traffic, and are more expensive than the train. Several shared-ride shuttles and regional buses also serve the airport, while driving yourself and parking on-site is widely available but costs more for long stays. The A-Line is generally the best balance of speed and value for most travelers.",
