        "question": "What is the typical flight duration from Seoul to Washington?",
        "answer": "The flight from Seoul to Washington is about 6,940 miles and typically takes 13 hours and 50 minutes nonstop. The return flight is longer at 15 hours and 25 minutes, a difference of 1 hour and 35 minutes due to prevailing winds.",
        "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.",

        "question": "Are there any direct flights from Seoul to Washington?",
        "answer": "Yes, Korean Air and Air Premia both fly nonstop from Seoul Incheon to Washington Dulles. Korean Air runs twice daily, every day of the week, while Air Premia operates four times a week on Mondays, Wednesdays, Fridays, and Sundays. The flight takes about 13 hours and 50 minutes eastbound.",
        "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, flight times and distances for this route come 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). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "answer": "Washington Dulles International Airport (IAD) offers several ground transportation options to reach the city center, including the Metrorail Silver Line, which connects the airport directly to downtown Washington, D.C. Taxis, ride-share services like Uber and Lyft, and rental cars are also available, with the Silver Line being the fastest and most-used option for reaching the city center. The Metrorail station is connected to the main terminal by an indoor pedestrian tunnel with moving sidewalks. For those preferring road transport, a dedicated access highway links the airport to the Capital Beltway. The Silver Line provides reliable, direct access to the heart of Washington, making it the top choice for most travelers.",

Connecting itineraries whose long leg is an overnight flight are available via New York JFK: Asiana Airlines (OZ) departs ICN at 21:05 and arrives at JFK at 23:00 the same night, then connects to American, Delta, or United for the short hop to IAD after a layover of roughly 7–7½ hours.",
        "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.",

        "question": "Which airport should I use in Washington?",
        "answer": "Washington Dulles is the main international gateway, located 26 miles west of downtown. Ronald Reagan Washington National is closer to the city centre and the National Mall but handles mostly domestic flights with limited international service. Baltimore/Washington International is farther north, offering a mix of domestic and international flights often with lower fares."
      },
      "q13": {
        "question": "How do I get to Incheon Intl Airport from the city center?",
        "answer": "From downtown Seoul, the fastest and most popular way to reach Incheon Intl Airport is the Airport Railroad (AREX), a dedicated express train that runs frequently and avoids traffic. Airport limousine buses are also widely used, with direct service from Seoul costing around 17,000 KRW for adults and requiring no advance reservation when boarding from the city. Taxis are available but cost significantly more, especially with night or boundary surcharges, while driving yourself is possible but parking at the airport adds expense and hassle. Ride-share services are limited in South Korea, so taxis or public transit are the standard choices.",
