        "question": "What is the typical flight duration from Baltimore to San Francisco?",
        "answer": "The flight from Baltimore to San Francisco is about 2,450 miles and typically takes 5 hours and 50 minutes. The return flight is shorter at 5 hours and 19 minutes, a difference of 31 minutes 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.",

        "question": "Are there any direct flights from Baltimore to San Francisco?",
        "answer": "Yes, United and Southwest both fly nonstop from Baltimore (BWI) to San Francisco (SFO), with a combined 70 weekly flights running daily. United offers up to 7 departures a day (early morning through evening) and Southwest up to 11, for roughly 10 flights each day. The nonstop flight takes about 5 hours 50 minutes, and United is the more reliable carrier on this route with an 84% on-time arrival rate.",
        "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. 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. 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.",

Ride-share services like Lyft and Uber pick up on Level 5 of the Domestic Garage, while taxis are at the arrivals center islands. Waymo autonomous rides are available for select passengers at the Rental Car Center. Rental cars and hotel shuttles are also options, with the Rental Car Center accessible via the AirTrain Blue Line.",

        "question": "When is the cheapest time to fly from Baltimore to San Francisco?",
        "answer": "Average fares from Baltimore to San Francisco bottom out around $336 in late January. The cheapest months overall are February at $345, January at $352, and September at $360, while the most expensive stretch is late December, averaging $471.",
        "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 Baltimore to San Francisco?",
        "answer": "For Baltimore to San Francisco, the optimal booking window is about 4-6 weeks before departure, when average fares drop to around $308. Booking around 45 days out yields the lowest single price at $307, while waiting until the last week or booking more than 5 months ahead pushes fares above $375. Summer and holiday periods likely shift the sweet spot earlier, but the core pattern holds: aim for roughly one to one-and-a-half months ahead.",
        "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.",

        "question": "How do I get to Thurgood Marshall Intl Airport from the city center?",
        "answer": "From downtown Baltimore, the fastest and most popular option is the MARC train, reached via a free shuttle from the airport terminal to the BWI Rail Station; the train takes about 30 minutes to Baltimore's Penn Station. A cheaper alternative is the MTA Light Rail, which also connects to the terminal and serves downtown, though it's slower. Ride-share services like Uber and Lyft, as well as taxis, offer door-to-door convenience at a higher cost, while driving yourself is possible with various on-airport parking options ranging from hourly to long-term lots.",
