        "question": "What is the typical flight duration from Denver to Baltimore?",
        "answer": "The flight from Denver to Baltimore is about 1,490 miles and typically takes 3 hours and 25 minutes nonstop. The return leg from Baltimore to Denver is longer, at 4 hours, due to prevailing winds. Southwest, Frontier, and United all operate nonstop service on this route.",
        "methodology": "Carrier service, flight times and distances for this route come 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). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates 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; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "answer": "Baltimore/Washington International (BWI) offers several ground transportation options: the free BWI Marshall Airport Shuttle connects to the BWI Rail Station for Amtrak and MARC trains, providing fast rail access to Baltimore and Washington. The MTA Light Rail also serves the airport, and MTA Commuter Bus 201 connects to the Shady Grove Metro station. Taxis are available 24/7 from the lower level, and app-based rides like Uber and Lyft pick up on the upper level. Rental cars are accessible via a free shuttle to the consolidated facility. The MARC train is the fastest way to reach downtown Baltimore, while the light rail is the most commonly used for local destinations.",

        "question": "When is the cheapest time to fly from Denver to Baltimore?",
        "answer": "The cheapest months to fly from Denver to Baltimore are January, February, and September, with average fares around $290–$304. December and June are the most expensive, averaging about $353 and $352 respectively.",
        "methodology": "This seasonal price baseline is a 365-day daily curve of typical round-trip fares for the route, precomputed monthly in-house from Priceline's own air booking-summary archive (the same data that backs the site), not a third party. For each calendar day we take a representative round-trip fare — a blend of the 25th-percentile and average ticket price over the route's bookings — and Gaussian-smooth the series so it reads as a clean seasonal trend rather than day-to-day noise. Thin and international routes are neighbor-filled: the seasonal shape is borrowed from the nearest dense routes (by origin-and-destination great-circle distance) with the price level anchored to the route's own bookings, so a sparse route still shows a plausible curve. It reflects current fares and is refreshed monthly.",

      "q5": {
        "question": "How far in advance should I book tickets from Denver to Baltimore?",
        "answer": "For flights from Denver to Baltimore, the best fares are typically found when booking 4 to 7 weeks ahead, with an average price around $240. The cheapest single day to book is about 35 days before departure at $239, while last-minute bookings (0 days out) can cost roughly $360. Fares tend to rise during summer and holiday periods, so booking even earlier—around 8 to 10 weeks out—is advisable for those peak times.",
        "methodology": "This booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. It expresses the typical round-trip fare as a function of how many days before departure a trip is booked — from about 180 days out down to the day of departure — aggregating the route's bookings by advance-purchase days and Gaussian-smoothing the curve the same way as the seasonal baseline. From that curve we highlight the stretch of lead times with the lowest average fare as the suggested booking window. Thin and international routes are neighbor-filled from the nearest dense routes, with the price level anchored to the route's own bookings. It reflects current fares and is refreshed monthly.",

        "question": "Are overnight (red‑eye) flights available from Denver to Baltimore?",
        "answer": "Overnight red-eye flights are available nonstop from Denver to Baltimore. Southwest offers up to 28 weekly red-eyes departing daily between 11:35 PM and 11:55 PM, while United operates a 11:45 PM departure six days a week (Monday through Saturday). These flights typically arrive at BWI in the early morning hours the next day.",
        "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, United, and Frontier fly nonstop from Denver to Baltimore. Southwest runs the most flights, with 171 a week, while United operates 41 weekly and Frontier about 9. Fares aren't listed in the schedule data, so typical prices aren't available.",
        "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.",

Southwest follows at 74% on‑time and a 0.9% cancellation rate, while Frontier arrives on time 74% of the time with no cancellations.",

        "question": "How do I get to Denver Intl Airport from the city center?",

Ride‑share services like Uber and Lyft, along with taxis, offer door‑to‑door convenience at a higher cost, while driving yourself means paying for on‑site parking. Several regional bus routes also serve the airport, providing a budget‑friendly alternative.",

        "question": "What aircraft are typically used on flights from Denver to Baltimore?",
        "answer": "On nonstop flights from Denver to Baltimore, the most common aircraft are the Boeing 737 MAX 8 and Boeing 737-800, operated by Southwest and United, with occasional appearances of the 737 MAX 9 and 737-900. For connecting itineraries, the same 737 variants dominate on Southwest via hubs like Nashville or Chicago–Midway, while American uses Airbus A321s and A319s through Charlotte or Dallas/Fort Worth. Specific aircraft can vary by day and airline, but Wi-Fi and seatback entertainment are widely available across these types.",
        "methodology": "Aircraft types are taken from the equipment each operating carrier schedules on this route, drawn from published airline timetables and airline equipment schedules in our flight-schedule database. They describe typical scheduled aircraft and can vary with seasonal or day-of-week assignments and last-minute equipment swaps.",

        "question": "Which airline alliances serve flights from Denver to Baltimore?",
        "answer": "Star Alliance, through United, is the only global alliance with nonstop service on the Denver–Baltimore route. Southwest and Frontier also fly the route nonstop but belong to no alliance — other alliances like oneworld and SkyTeam do not have a nonstop presence here, though they may offer connecting itineraries.",
        "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, flight times and distances for this route come 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). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates 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; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",
