        "question": "What is the typical flight duration from Seoul to Washington?",
        "answer": "The flight from Seoul to the Washington area covers about 6,940 miles. Nonstop service typically takes 13 hours 50 minutes eastbound, while the return leg against the jet stream is longer at 15 hours 25 minutes.",
        "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.",

Korean Air runs twice daily (14 flights a week), while Air Premia operates four times a week on Monday, Wednesday, Friday, and Sunday. The nonstop flight takes roughly 13–14 hours eastbound.",

        "question": "What are the ground transportation options in Washington?",
        "answer": "Washington Dulles International Airport (IAD) offers several ground transportation options to the city center, including Metrorail's Silver Line, taxis, ride-share services, and car rentals. The Silver Line station is connected to the main terminal via an indoor pedestrian tunnel with moving sidewalks, providing a direct, reliable, and affordable rail link to downtown Washington. Taxis and ride shares offer door-to-door convenience but are more expensive and subject to traffic, while car rentals provide flexibility for onward travel. The Metrorail is the most-used option for budget-conscious travelers, while taxis and ride shares are favored for speed and convenience, especially with luggage. Overall, the Silver Line is the fastest and most efficient public transit option, though a taxi or ride share may be quicker for door-to-door trips depending on traffic.",

        "question": "Which airport should I use in Washington?",
        "answer": "Washington Dulles is the primary international gateway, located about 26 miles west of downtown, and is a major United hub with many global connections. Ronald Reagan National is just across the Potomac, very close to central DC and the National Mall, but mainly serves domestic and limited international flights. Baltimore/Washington International is farther north, offers a mix of domestic and some international service, and is a Southwest focus city."

      "q13": {
        "question": "How do I get to Incheon Intl Airport from the city center?",
        "answer": "From downtown Seoul, the Airport Railroad Express (AREX) is the fastest and most popular way to reach Incheon International Airport, with frequent service from Seoul Station. Airport limousine buses provide convenient direct service from major city stops like the express bus terminal, with fares around 17,000 KRW, and can be paid by transportation card or credit card without reservation. Taxis are available but cost significantly more, with a base fare of 4,800 KRW plus distance and possible surcharges, while driving and parking at the airport is possible but generally less convenient for travelers. Ride-share services operate in Seoul but are less common than taxis for airport trips.",
