        "question": "What is the typical flight duration from Boston to Denver?",
        "answer": "The flight from Boston to Denver covers about 1,750 miles and typically takes 4 hours 35 minutes. The return leg is around 4 hours 0 minutes, about 35 minutes shorter 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.",

The RTD A Line train is the fastest and most-used option, reaching downtown's Union Station in about 37 minutes with trains every 15 minutes, 24/7; it's ideal for budget travelers. Ride-share services like Uber and Lyft and taxis take 25-35 minutes and are best for convenience and immediate service, available 24/7 on Level 5. Shared vans (45-60 minutes) and car rentals from over 10 major companies are also available, along with hotel shuttles and charter buses for groups.",

        "question": "When is the cheapest time to fly from Boston to Denver?",
        "answer": "Average fares from Boston to Denver bottom out around $275 in early January, with January overall the cheapest month at about $277. November and September are also relatively affordable, averaging $317 and $321 respectively, while late December is the priciest stretch at around $387.",
        "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 Boston to Denver?",
        "answer": "For flights from Boston to Denver, the best fares typically come when you book about 3 to 6 weeks before departure, with the very lowest prices around 25 days out, averaging about $258. Booking much earlier — say 4 to 6 months ahead — tends to cost more, around $300 or higher. Summer and holiday periods generally require booking even further in advance to avoid sharp price jumps, since demand is higher.",
        "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 leads with roughly 89 weekly flights and a median fare around $471, while Southwest offers about 83 weekly flights at a typical $305. JetBlue operates 27 weekly nonstops at a median $430, and Delta has 14 weekly flights with a median fare near $478.",
        "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.",

        "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.

        "question": "How do I get to Logan Intl Airport from the city center?",
        "answer": "From downtown Boston to Logan Airport, the MBTA Silver Line SL1 bus is the most affordable and popular option, running free from the airport to South Station and connecting directly to all terminals; the Blue Line subway plus a free shuttle is another public transit choice. Ride-share services like Uber and Lyft, as well as taxis from designated stands, offer door-to-door convenience at a higher cost. Driving and parking are available with Central Parking closest to terminals, Economy Parking with free shuttles for long-term stays, and advance reservations offering discounted daily rates. The Logan Express bus also serves Back Bay and other suburban locations for a comfortable middle-ground option.",

        "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.",

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.",
