        "question": "What is the typical flight duration from Denver to Columbus?",
        "answer": "Flights from Denver to Columbus are about 1,150 miles and typically take 2 hours 45 minutes nonstop. The return flight to Denver usually takes 3 hours 10 minutes, about 25 minutes longer due to prevailing winds.",
        "methodology": "Flight times and distances come 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

        "answer": "From John Glenn Columbus International Airport, the Central Ohio Transit Authority (COTA) bus route 7 Mt. Vernon connects the airport directly to downtown Columbus. Taxi services are available through numerous Columbus-area taxi companies, and a dedicated ground transportation area serves the terminal. Rental car facilities are located on-site, having moved into a new building in 2021 with electric shuttle buses to the terminal. On-site parking includes a six-story garage plus budget satellite lots at $5–$9 per 24 hours. COTA bus is the most-used public transit link to the city center, while taxis and rental cars offer the fastest direct door-to-door options.",

        "question": "When is the cheapest time to fly from Denver to Columbus?",
        "answer": "Average fares from Denver to Columbus bottom out around $298 in late October, the cheapest stretch of the year. October, February, and January are the cheapest months overall, with averages of $301, $306, and $309 respectively. The priciest period is late December at $391, while December and June tie as the most expensive months at $371 on average.",
        "methodology": "Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.",

        "question": "How far in advance should I book tickets from Denver to Columbus?",
        "answer": "For flights from Denver to Columbus, the best fares are typically found when booking 4–6 weeks before departure, with the absolute lowest price around 30 days out at about $262. Booking much earlier, such as 20+ weeks ahead, tends to cost significantly more, often $400 or higher. Fares are generally lowest in that 4–6 week window and rise sharply for last-minute bookings; summer and holiday periods may require booking even earlier to catch better prices.",
        "methodology": "Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.",

        "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.",

United Airlines also flies the route non‑stop, offering 22 weekly flights, while Frontier provides limited non‑stop service on Mondays, Thursdays, Fridays and Sundays with 9 weekly departures.",

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.

        "question": "How reliable are on‑time arrivals on this route from Denver to Columbus?",
        "answer": "On the Denver to Columbus route, United Airlines has the best on-time arrival record at 77%, with a cancellation rate of just 0.2%. Frontier follows at 76.3% on-time but cancels 1.7% of flights, while Southwest arrives on time 63.7% of the time and cancels 0.3%.",
        "methodology": "On-time arrival 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; a flight counts as on time when it arrives within 15 minutes of schedule. Carriers are ranked by arrival on-time rate on this route, and the carrier list itself comes 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).",

      },
      "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 typically ride-share (Uber/Lyft) or a taxi, both taking about 25–35 minutes and costing more than public transit. The RTD A Line train runs every 15 minutes, 24/7, and reaches downtown in about 37 minutes for a budget-friendly fare, while shared shuttle vans are a mid-cost option for groups or hotel drop-offs. Driving and parking at DEN is also possible, with multiple on-airport lots and off-site rental car shuttles, though parking fees add to the cost. Ride-share is generally the most convenient choice for solo travelers, while the train is best for budget-conscious riders.",
