        "question": "What is the typical flight duration from Baltimore to Paris?",
        "answer": "There are no nonstop flights from Baltimore (BWI) to Paris (CDG/ORY). A typical one-stop flight takes 9.5 to 11.5 hours total travel time, depending on the layover. Common connecting cities include Reykjavik (KEF) on Icelandair, London (LHR) on British Airways, and various U.S. East Coast hubs. The return flight is often about 1–1.5 hours longer due to prevailing headwinds."
      },
      "q1": {
        "question": "Are there any direct flights from Baltimore to Paris?",
        "answer": "There are no nonstop flights from Baltimore (BWI) to Paris (PAR). The shortest one-stop routings typically connect via London Heathrow (LHR) on British Airways, with a long leg of about 7 hours 35 minutes, a layover around 2 hours 20 minutes, and a short second leg of roughly 1 hour 15 minutes, totaling about 11–12 hours of travel time.",
        "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. Carrier service and weekly frequencies are summarized 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). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "question": "Are there visa requirements to travel from Baltimore to Paris?",
        "answer": "Yes, visa requirements apply for travel from Baltimore, Maryland to Paris, France. U.S. citizens can visit France for up to 90 days without a visa for tourism or business, but must have a passport valid for at least three months beyond their intended stay. Starting in 2025, U.S. citizens will also need to obtain an ETIAS travel authorization before travel. Non-U.S. citizens may require a Schengen visa depending on their nationality. Travelers should check current requirements based on their specific citizenship."

      "q3": {
        "question": "What are the ground transportation options in Paris?",
        "answer": "Paris is served by two main airports, Charles de Gaulle (CDG) and Orly (ORY). From CDG, the RER B train reaches central stations like Châtelet-Les Halles in about thirty-five minutes and is the most used and cost-effective option. Roissybus provides a direct bus to Opéra in roughly sixty minutes, while taxis and ride-shares take forty-five minutes to over an hour depending on traffic, with flat fares to the right and left banks. From Orly, the Orlyval light rail connects to the RER B at Antony in about thirty minutes total, and the new Metro Line 14 extension offers a direct ride to central Paris in around twenty-five minutes. Taxis and ride-shares from Orly take thirty to forty-five minutes. Car rentals are available at both airports but are impractical for city visits due to heavy traffic and limited parking. Most travelers rely on the RER B from CDG and the Metro Line 14 from Orly for their speed and reliability."

        "question": "When is the cheapest time to fly from Baltimore to Paris?",
        "answer": "Based on seasonal price data, the cheapest months to fly from Baltimore to Paris are November (average $878), March ($880), and October ($892), while the most expensive months are June ($1331), May ($1198), and December ($1174).",
        "methodology": "This 'good deal' estimate shows a representative best price for each departure date across roughly a 12-month window (about 3 months back and 9 months forward). It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise.",

      "q5": {
        "question": "How far in advance should I book tickets from Baltimore to Paris?",
        "answer": "For flights from Baltimore to Paris, the optimal booking window is generally 6 to 9 weeks before departure, with the best prices averaging around $911 and the lowest single fare found at 50 days out ($896). Booking too late (within 2 weeks) can push prices above $1,700, while booking more than 4 months ahead also tends to be more expensive. Summer and holiday periods likely require booking earlier, around 3 to 4 months in advance, to avoid peak pricing.",
        "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row.",

However, connecting overnight itineraries are available, typically departing BWI in the late evening (around 8:30 PM to 11:20 PM) and arriving in Paris the next morning after a layover in Reykjavik (KEF) or London (LHR).",
        "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": "Charles de Gaulle is the primary international gateway, located about 25 km northeast of central Paris, and is a hub for Air France and SkyTeam, with extensive global connections. Orly is closer, roughly 13 km south of the city centre, handling mostly domestic and European flights, with a strong presence of low‑cost carriers like Transavia and Vueling. Beauvais is far from Paris, used almost exclusively by Ryanair for budget flights, and requires a lengthy bus transfer."

      "q13": {
        "question": "How do I get to Thurgood Marshall Intl Airport from the city center?",
