        "question": "What is the typical flight duration from New York to Seoul?",
        "answer": "A nonstop flight from New York (JFK) to Seoul (ICN) typically takes about 14 to 15 hours eastbound. Westbound, the return flight is usually shorter at around 13 to 14 hours due to prevailing winds. With one stop, common layovers include Tokyo, Beijing, or European hubs, and total travel time often ranges from 17 to 20 hours or more. Korean Air and Asiana offer the fastest nonstop services."
      },
      "q1": {
        "question": "Are there any direct flights from New York to Seoul?",
        "answer": "Yes, there are nonstop flights from New York JFK to Seoul (ICN) on two airlines: Korean Air (KE) and Asiana Airlines (OZ), both operating daily with multiple departures — Korean Air runs four flights a day (around 12:50 AM, noon, 1:00 PM, and 1:20 PM) and Asiana also runs four daily (around 1:30 AM, 11:15 AM, 11:45 AM, and 12:15 PM).",
        "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 New York to Seoul?",
        "answer": "Yes, there are visa requirements. For U.S. citizens traveling from New York to Seoul, South Korea currently allows visa-free entry for tourism or business for up to 90 days under the K-ETA (Korea Electronic Travel Authorization) program. You must apply for and receive K-ETA approval before departure. For South Korean nationals traveling to the U.S., they can generally enter under the Visa Waiver Program with an approved ESTA for stays up to 90 days. Nationals of other countries should check both South Korean and U.S. entry requirements based on their citizenship."

      "q3": {
        "question": "What are the ground transportation options in Seoul?",
        "answer": "Seoul has two main airports: Incheon International (ICN) and Gimpo International (GMP). From Incheon, the AREX Express train reaches Seoul Station in about forty-three minutes non-stop, while the all-stop AREX commuter train takes roughly sixty minutes. Airport limousine buses serve many city districts in sixty to ninety minutes, depending on traffic. Taxis and ride-share services are available but can be expensive and slow during peak hours. Car rentals are offered but not recommended for city travel due to heavy traffic and parking difficulties. Most travelers use the AREX Express for its speed and reliability. From Gimpo, which mainly serves domestic and some regional flights, the AREX all-stop train and subway Line 5 and Line 9 connect to central Seoul in about thirty to forty minutes. Buses and taxis are also available. The all-stop AREX train is the most used option from Gimpo."

        "question": "When is the cheapest time to fly from New York to Seoul?",
        "answer": "Based on seasonal price data for flights from New York JFK to Seoul, the cheapest months are September (around $994), October (around $1004), and November (around $1010), while the most expensive months are June (around $1398), December (around $1382), and July (around $1285).",
        "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.",

        "question": "How far in advance should I book tickets from New York to Seoul?",
        "answer": "For flights from New York (JFK) to Seoul, the optimal booking window is about 23 to 26 weeks in advance, when average prices hover around $1,405. Booking around 180 days ahead can yield the lowest fare of approximately $1,391, while last-minute purchases within a few weeks of departure often exceed $1,500. During summer and holiday peaks, it's wise to book even earlier—closer to 30 weeks out—as demand drives prices higher.",
        "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 New York to Seoul?",
        "answer": "There are no nonstop red-eye flights from New York (JFK) to Seoul (SEL). One-stop connecting itineraries with an overnight leg exist, such as a Finnair routing via Helsinki where the Helsinki-to-Seoul segment departs at 5:30 PM and arrives the next morning at 11:20 AM, but no direct overnight service is available.",
        "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": "Nonstop flights from New York JFK to Seoul are operated by Korean Air and Asiana Airlines, both serving Incheon Airport (ICN) with about 28 weekly flights each, departing at various times throughout the day. Typical median fares are around $1,634 on Korean Air and $1,997 on Asiana Airlines. Both carriers offer daily service, so you have two solid nonstop options on this route.",

        "question": "What documents should I bring with me to the airport when flying from New York to Seoul?",
        "answer": "For international travel from New York (JFK) to Seoul, bring a valid passport. South Korea requires a passport valid for the duration of your stay. Most U.S. tourists can enter visa-free under the K-ETA program, so apply online before departure. Have your K-ETA approval, proof of onward or return travel, and a payment method for baggage. Vaccination certificates are not currently required, but check for any health entry requirements before your trip."

      "q12": {
        "question": "Which airport should I use in Seoul?",
        "answer": "Seoul has two main airports: Incheon International Airport (ICN) is the primary gateway for international flights, located about 30 miles west of downtown Seoul. It serves as a hub for Korean Air and Asiana Airlines (both SkyTeam and Star Alliance partners) and offers extensive long-haul connections. Gimpo International Airport (GMP) is much closer to the city center, roughly 10 miles away, and handles mostly domestic flights and some short-haul international routes to Japan, China, and Taiwan. For international arrivals from New York, you will almost certainly land at Incheon."
      },
      "q13": {
        "question": "How do I get to John F Kennedy Intl Airport from the city center?",
        "answer": "From Midtown Manhattan to JFK, the AirTrain from Jamaica or Howard Beach via subway or LIRR is the cheapest and often fastest during peak hours, taking about 50–60 min. Rideshares and taxis take 45–90 min depending on traffic and cost more. Shuttles and parking are available."
