        "question": "What is the typical flight duration from New York City to Seoul?",
        "answer": "A nonstop flight from New York (JFK) to Seoul (ICN) typically takes about 14 hours 30 minutes to 15 hours. With one stop, depending on the connection city, total travel time often ranges from 17 to 20 hours."
      },
      "q1": {
        "question": "Are there any direct flights from New York City to Seoul?",
        "answer": "Yes, two airlines fly nonstop from JFK to Seoul Incheon: Korean Air and Asiana Airlines, both operating daily. Korean Air runs four daily flights (departing around 12:50 AM, noon, 1:00 PM, and 1:20 PM) while Asiana also offers four daily departures (around 1:30 AM, 11:15 AM, 11:45 AM, and 12:15 PM), giving travelers a combined 56 weekly nonstop options.",
        "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 New York City to Seoul?",
        "answer": "Yes, visa requirements depend on your nationality. For U.S. citizens traveling from New York to Seoul, no visa is required for stays up to 90 days for tourism or business; you must have a valid K-ETA (Korea Electronic Travel Authorization) prior to travel. For South Korean citizens traveling to New York, a visa is generally required unless they are eligible for the Visa Waiver Program, which allows stays up to 90 days with an approved ESTA. Other nationals should check both countries' entry requirements."
      },
      "q3": {
        "question": "What are the ground transportation options in Seoul?",
        "answer": "From Incheon Airport, the Airport Railroad (AREX) express train to Seoul Station is the fastest and most popular option, taking about 43 minutes and costing 8,000 won. Limousine buses serve many city districts and hotels directly, with fares around 17,000 won, but travel times vary with traffic. Taxis and ride‑share services are available at the terminals, though they are generally more expensive and subject to road congestion. Car rentals are on‑site but are rarely used for a simple city transfer. For most travelers, the AREX express train is the most‑used and efficient choice.",

      "q4": {
        "question": "When is the cheapest time to fly from New York City to Seoul?",
        "answer": "The cheapest months to fly from New York City to Seoul are November, October, and September, with average fares around $852, $884, and $909 respectively. The most expensive months are June, December, and May, averaging $1364, $1291, and $1226. Late summer through early fall offers the lowest prices, while early summer and the holiday season see the highest fares.",
        "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 New York City to Seoul?",
        "answer": "For flights from New York JFK to Seoul, the optimal booking window is 19 to 22 weeks before departure, with an average fare around $1,405. Booking about 145 days out can yield the lowest price near $1,400. For summer and holiday periods, it's wise to lean toward the early end of that range, as prices tend to rise closer to peak travel dates.",
        "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.",

        "answer": "Overnight (red-eye) flights from New York JFK to Seoul ICN are available as connecting itineraries via San Francisco (SFO). The long overnight leg is United's SFO→ICN, departing at 11:55 PM and arriving at 4:20 AM — landing in the early hours of the morning. You would first fly United from JFK to SFO, with a layover of about 56 minutes before the red-eye to Seoul.",
        "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": "Korean Air and Asiana Airlines both operate non‑stop from New York JFK to Seoul Incheon, each with 28 weekly flights — essentially four daily departures. Korean Air’s median fare is around $1,896 and Asiana’s about $1,949. Flights leave throughout the day, including late‑night and midday options.",

      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from New York City to Seoul?",
        "answer": "On-time performance is generally good, but afternoon and evening flights can be delayed by air traffic or weather. Early morning departures, particularly on Korean Air and Asiana, tend to have higher reliability."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to Seoul?",

      },
      "q12": {
        "question": "Which airport should I use in Seoul?",
        "answer": "Seoul has two airports. Incheon is the primary international gateway, located 48 km west of central Seoul, and serves most full‑service airlines. Gimpo is closer to downtown, about 15 km away, and handles mainly domestic flights and some short‑haul international routes to China and Japan."
      },
      "q13": {
        "question": "How do I get to John F Kennedy Intl Airport from the city center?",
        "answer": "From Midtown Manhattan, the fastest and most popular option is the AirTrain combined with the Long Island Rail Road (LIRR) from Jamaica Station, taking about 35 minutes total; the subway (E, J, or Z line to Sutphin Blvd–Archer Av–JFK Airport) plus AirTrain is more economical but slower. Taxis offer a flat fare to Manhattan and take 45–60 minutes in typical traffic, while ride‑share services like Uber and Lyft vary with demand. Driving and parking are available but costly and subject to congestion; shared shuttle vans and the new Uber Shuttle provide a middle ground in price and convenience.",
