        "question": "What is the typical flight duration from Tokyo to Seoul?",
        "answer": "A direct flight from Tokyo (HND) to Seoul (ICN) typically takes about 2 hours 20 minutes to 2 hours 30 minutes. The return flight from Seoul to Tokyo is similar, usually around 2 hours 10 minutes to 2 hours 20 minutes due to tailwinds. With a layover, total time can range from 5 to 8 hours, depending on the connection city."

      "q1": {
        "question": "Are there any direct flights from Tokyo to Seoul?",
        "answer": "Yes, there are nonstop flights from Tokyo Haneda (HND) to Seoul Incheon (ICN) operated by three airlines — Asiana Airlines (OZ), Peach Aviation (MM), and Korean Air (KE) — all running daily. Peach offers two daily departures (around 1:55 AM and 2:10 AM), while Asiana and Korean Air each offer one daily departure (around 1:30 AM and 2:00 AM respectively), giving a total of four daily nonstop flights.",

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).

        "question": "What are the ground transportation options in Seoul?",
        "answer": "From Incheon International Airport (ICN) to Seoul city center, you have several ground transportation options. The Airport Railroad Express (AREX) is the most popular choice: the non-stop Express Train reaches Seoul Station in about 43 minutes, while the All-Stop Train takes around 60 minutes and is cheaper. Airport limousine buses serve various districts and hotels, taking roughly 60 to 90 minutes depending on traffic. Taxis are available but expensive, with a typical fare to central Seoul costing between KRW 55,000 and 80,000 and a travel time of 60 to 90 minutes. Ride-share services like Kakao T are widely used. Car rentals are available but not recommended for city travel due to heavy traffic and limited parking. Most travelers use the AREX train for its speed, reliability, and cost-effectiveness."

        "question": "Are overnight (red‑eye) flights available from Tokyo to Seoul?",
        "answer": "There are no nonstop red-eye flights from Tokyo (HND) to Seoul (ICN). The schedule data shows only connecting overnight options — for example, a routing via UBN (Ulaanbaatar) on OM with the long leg departing NRT at 21:30 and arriving at 02:05, but that involves a stop and a long layover rather than a direct late-evening departure from HND.",
        "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.",
