        "question": "What is the typical flight duration from Tokyo to Seoul?",
        "answer": "The flight from Tokyo to Seoul is about 730 miles and typically takes 2 hours and 30 minutes. The return leg from Seoul to Tokyo is shorter at about 2 hours and 10 minutes due to prevailing winds. Nonstop service is available on multiple carriers, including JAL, Asiana, ANA, and Korean Air.",
        "methodology": "Flight times and distances come 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

        "answer": "Gimpo International Airport sits directly on Seoul's excellent rail network, with the AREX line and Seoul Subway Lines 5 and 9, plus the Gimpo Goldline and Seohae Line, all serving the airport station, making rail the fastest and most-used way into the city center. Taxis are also readily available, with regular metered cabs and a premium deluxe tier, and international taxis with English-speaking drivers for a surcharge. The integrated Tmoney card works seamlessly across subway and city buses, which are extensive and highly regarded for efficiency. For most travelers, the subway or AREX is the clear best choice, though taxis offer a comfortable alternative for those with luggage or late-night arrivals.",

        "question": "If I need a connection, what are common layover cities between Tokyo and Seoul?",
        "answer": "Direct flights are plentiful on this short route, so connections are rarely needed. If you do connect, common hubs include Osaka (KIX), Fukuoka (FUK), Busan (PUS), and Beijing (PEK). Osaka and Fukuoka offer efficient domestic transfers within Japan or quick hops to Seoul, while Busan provides a nearby Korean gateway with smooth connections to Gimpo. Beijing can be an option on some itineraries, though it adds significant flight time and may require a Chinese transit visa depending on your nationality; verify current entry rules before booking."

        "question": "How do I get to Haneda Intl Airport from the city center?",
        "answer": "From central Tokyo, the fastest and most popular way to reach Haneda Airport is by train: the Keikyu Line or Tokyo Monorail, both frequent and relatively inexpensive. Airport shuttle buses serve Tokyo, Kanagawa, Chiba, Saitama, and other Kanto areas, and are a convenient mid-priced option. Taxis and ride-share services are available but are the most expensive and subject to traffic, while driving is possible with several parking lots at the domestic and international terminals, though parking can be costly and congested during peak periods.",
