        "question": "What is the typical flight duration from Baltimore to Denver?",
        "answer": "The flight from Baltimore to Denver is about 1,490 miles and typically takes 4 hours nonstop. The return leg is shorter, around 3 hours 25 minutes, because prevailing winds slow the westbound trip. Southwest, United, and Frontier all serve the route with nonstop service.",
        "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": "Denver International Airport (DEN) offers several ground transportation options to the city center: the RTD A Line train (37 minutes, $10 day pass, best for budget travelers), ride-share services like Uber/Lyft (25–35 minutes, most convenient), taxis (25–35 minutes, 24/7 availability), shared vans (45–60 minutes, good for hotel drop-offs), and car rentals from over 10 major companies via a free shuttle. The A Line train is the most-used and often fastest reliable option, running every 15 minutes to downtown Union Station. Ride-share is the most popular for door-to-door convenience, while taxis are best for immediate service.",

        "question": "When is the cheapest time to fly from Baltimore to Denver?",
        "answer": "Average fares from Baltimore to Denver bottom out around $288 in early January, making it the cheapest stretch to fly. The cheapest months overall are January ($289), September ($298), and October ($305), while the most expensive period is late December, with average fares around $375. Overall, June, December, and March tend to be the priciest months on this route.",
        "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.",

      "q5": {
        "question": "How far in advance should I book tickets from Baltimore to Denver?",
        "answer": "For Baltimore to Denver, the best fares generally come when booking about 4 to 6 weeks ahead, with prices averaging around $249 and a sweet spot near 30–35 days out. Booking too early (5–6 months ahead) can push fares up toward $360+, and the same applies to peak summer and holiday travel, when you should lean toward the earlier end of that window or expect to pay more.",
        "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.",

Typical departure times range from 9:00 PM to 10:35 PM, and these flights arrive in Denver the same night, generally before midnight local time.",
        "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.",

        "answer": "Southwest Airlines is the dominant carrier on the Baltimore to Denver route with 168 weekly nonstop flights, departing throughout the day from early morning until late evening. United also flies this route nonstop with 34 weekly flights, and Frontier offers 6 weekly nonstops on select days. Southwest's typical median fare on this route is around $168.",
        "methodology": "Airlines and weekly frequencies 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). 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 typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.",

Southwest follows at 74.3% on-time arrivals and a 0.9% cancellation rate, while Frontier trails at 52.3% with the same 0.9% cancellation rate.",
        "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).",

        "question": "Which airport should I use in Denver?",

      },
      "q13": {
        "question": "How do I get to Thurgood Marshall Intl Airport from the city center?",
        "answer": "From downtown Baltimore, the MTA Light Rail offers direct service to BWI Airport for about $2 each way, taking roughly 30-40 minutes from the city center. Taxis are available at the airport's lower-level taxi stand, and ride-share services like Uber and Lyft pick up on the departures/ticketing level; both are more expensive than light rail but faster, especially outside rush hour. Driving yourself is also an option, with on-airport parking lots connected by free 24/7 shuttles, though parking fees add to the cost. The light rail is the most popular and affordable choice for solo travelers, while ride-share or taxi is fastest for door-to-door convenience.",

        "question": "What aircraft are typically used on flights from Baltimore to Denver?",
        "answer": "Southwest flies the Baltimore–Denver route most often, using Boeing 737 family aircraft. United operates Boeing 737-800s and Boeing 737 family aircraft on the route, while Frontier uses Airbus A320 family aircraft.",
        "methodology": "Aircraft types 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). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.",

        "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.",
