        "question": "What is the typical flight duration from Washington to Seoul?",
        "answer": "The nonstop flight from Washington Dulles to Seoul Incheon is about 6,940 miles and typically takes 15 hours and 25 minutes, with Korean Air and Air Premia operating the route. The return leg is noticeably faster at 13 hours and 50 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.",

      "q1": {
        "question": "Are there any direct flights from Washington to Seoul?",
        "answer": "Yes, Korean Air and Air Premia both fly nonstop from Washington Dulles (IAD) to Seoul Incheon (ICN). Korean Air operates daily with multiple departures, while Air Premia flies four days a week — Monday, Wednesday, Friday, and Sunday. The nonstop flight takes about 15 hours 25 minutes, with typical fares around $1,584 on Korean Air.",
        "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. 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. Stop counts, connecting hubs, and per-airline prices are drawn from a large sample of the real fares Priceline users found on this route in the last 72 hours. We group those fares by number of stops, by the hub airport a connection routes through, and by operating airline, and report each group's share of the sample alongside its lowest and median price.",

However, a Korea Electronic Travel Authorization must be obtained before travel.\n\nThis is general guidance to help you plan, not official immigration advice — entry rules can change and can depend on your nationality and circumstances, so please confirm the current requirements with the relevant embassy or official government source before you travel.",

Limousine buses are a comfortable alternative, with fares around 17,000 KRW for a direct route to Seoul, though they are slower in traffic. Taxis are available in standard and deluxe/jumbo sizes, with base fares of 4,800 KRW for standard taxis from Seoul, plus a 20-30% night surcharge between 22:00 and 04:00. Ride share and car rental are not prominently offered at the airport, and most travelers prefer the train or bus for cost and reliability.",

For example, United offers a connection via San Francisco where the overnight leg SFO→ICN departs at 11:55 PM and arrives at 4:20 AM (early hours), and Asiana offers similar red-eye legs via Los Angeles (departing 11:00 PM, arriving 4:00 AM) or San Francisco (departing 11:20 PM, arriving 4:05 AM).",

        "question": "How do I get to Washington Intl Airport from the city center?",
        "answer": "From downtown Washington, DC, the easiest public transit option to reach Dulles International Airport is the Metro Silver Line, which stops directly at the airport terminal via an indoor pedestrian tunnel with moving sidewalks. Ride-share services like Uber and Lyft, taxis, and dedicated airport shuttle buses are also readily available and offer door-to-door convenience, though they cost more than the Metro. Driving yourself is possible, with several on-site parking garages and lots connected to the terminal, but parking rates and traffic make it the least budget-friendly choice during peak hours. The Metro is generally the most popular and cost-effective option for solo travelers, while ride-share or taxi is fastest for those with luggage or tight schedules.",
