        "question": "What is the typical flight duration from Boston to Seoul?",
        "answer": "There are no nonstop flights from Boston (BOS) to Seoul (ICN). A typical one-stop itinerary takes 16 to 18 hours eastbound, depending on the layover city. Common connecting points include Detroit, Atlanta, and European hubs, and the return trip westbound often runs about an hour longer due to prevailing winds."
      },
      "q1": {
        "question": "Are there any direct flights from Boston to Seoul?",
        "answer": "Korean Air flies nonstop from Boston (BOS) to Seoul Incheon (ICN) with 21 weekly flights — three daily departures at 11:00 AM, 12:00 PM, and 12:55 PM, operating every day of the week. It's the only airline offering nonstop service on this route.",
        "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 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 Boston to Seoul?",
        "answer": "Yes, visa requirements apply for travel between Boston and Seoul. U.S. citizens can enter South Korea without a visa for stays up to 90 days for tourism or business, but must have a valid K-ETA (Korea Electronic Travel Authorization) before travel. South Korean citizens can travel to the U.S. under the Visa Waiver Program for stays up to 90 days, provided they have an approved ESTA. Other nationalities should check specific visa requirements for both countries."

      "q3": {
        "question": "What are the ground transportation options in Seoul?",
        "answer": "From Incheon International Airport, the fastest way to Seoul city center is the AREX express train, taking about 43 minutes to Seoul Station and costing 8,000 won. The all-stop commuter train is a cheaper rail option at around 4,150 won, while airport limousine buses serve many districts with fares around 17,000 won. Taxis and ride-share services are available but more expensive and subject to traffic. The AREX train is the most used option by travelers for its speed and reliability.",

      "q4": {
        "question": "When is the cheapest time to fly from Boston to Seoul?",
        "answer": "The cheapest time to fly from Boston to Seoul is in the fall, particularly September through November, with average fares around $1,283–$1,376. The most expensive months are December, June, and July, when average prices climb to $1,764–$1,800.",
        "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 Boston to Seoul?",
        "answer": "For flights from Boston to Seoul, the best fares typically appear when booking 12 to 15 weeks ahead, with the lowest price around $1,672 at about 95 days out. Prices rise sharply within three weeks of departure, so booking at least two months in advance is advisable, and for peak summer or holiday travel, aiming for the early side of that window—around four months ahead—can help avoid higher fares.",
        "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.",

        "question": "Are overnight (red‑eye) flights available from Boston to Seoul?",
        "answer": "No nonstop red-eyes operate from Boston to Seoul, but connecting red-eye itineraries are available. The overnight long leg departs Los Angeles at 11:00 PM (arriving Seoul at 4:00 AM) or San Francisco at 11:20 PM–11:55 PM (arriving 4:05–4:20 AM), with the connecting feeder from Boston on JetBlue or United. All arrivals land in the early hours (just after 4:00 AM).",
        "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.",

        "question": "Which airlines usually operate this route from Boston to Seoul?",
        "answer": "Korean Air is the only airline flying nonstop from Boston to Seoul, with 21 weekly departures on a daily schedule. While other carriers may also serve this route via connections, Korean Air offers the sole direct option. No per-carrier fare data is available for this route, so typical prices are not provided.",

      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Boston to Seoul?",
        "answer": "Reliability is generally good, though long-haul flights can be subject to cumulative delays. Opting for early morning departures, particularly on Korean Air, can improve your chances of an on-time takeoff."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to Seoul?",

      "q12": {
        "question": "Which airport should I use in Seoul?",
        "answer": "Incheon International is the primary gateway for international flights to Seoul, with extensive global connections and modern facilities. Gimpo International mainly serves domestic and short‑haul regional flights, and is closer to downtown."
      },
      "q13": {
        "question": "How do I get to Logan Intl Airport from the city center?",
        "answer": "From downtown Boston, the fastest and most popular option is the MBTA Silver Line SL1 bus, which is free from South Station and offers a direct ride to all terminals. The Logan Express bus from Back Bay is another convenient choice with a low fare of $3 to the airport. Taxis and ride-shares like Uber and Lyft provide door-to-door service at a higher cost, while driving yourself is possible but parking at Logan is expensive, starting at $29 per day.",
