        "question": "What is the typical flight duration from Kathmandu to Washington?",
        "answer": "The flight distance from Kathmandu to Washington is about 7,700 miles. There is no scheduled nonstop service on this route, so the journey requires at least one connection. A typical one-stop total travel time is approximately 20 to 24 hours, depending on the layover.",
        "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": "What are the ground transportation options in Washington?",
        "answer": "Washington Dulles International Airport (IAD) is connected to downtown Washington, D.C. via the Silver Line of the Metrorail system, which has a station directly at the airport linked by an indoor pedestrian tunnel; this is the most-used and generally most reliable public transit option, taking about 50–60 minutes to reach the city center. Taxis, ride-share services like Uber and Lyft, and rental cars are also readily available at the airport, with taxis and ride-shares offering door-to-door convenience but subject to traffic on the Dulles Access Road and I-66. The Metrorail is the fastest predictable option during peak traffic, though a taxi or ride-share can be faster late at night when roads are clear. The Silver Line station is the primary mass transit link and handles the majority of airport-to-city trips for budget-conscious travelers.",

        "question": "When is the cheapest time to fly from Kathmandu to Washington?",
        "answer": "Average fares from Kathmandu to Washington bottom out around $406 in late September, making that the cheapest stretch to fly. September, October, and February are the cheapest months overall, averaging $420, $425, and $449 respectively. The most expensive period is late December, when average fares climb to about $563.",
        "methodology": "Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.",

        "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.",

        "answer": "There are no nonstop flights from Kathmandu to Washington, but several airlines offer one-stop connections. Qatar Airways routes through Doha, with about nine daily departures on the search date. Emirates connects via Dubai on approximately four daily flights, and Turkish Airlines offers around two daily flights through Istanbul. Other carriers may also serve this route with different connections.",
        "methodology": "Airlines and weekly frequencies 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). 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.

        "question": "What documents should I bring with me to the airport when flying from Kathmandu to Washington?",

      },
      "q12": {
        "question": "Which airport should I use in Washington?",
        "answer": "Washington Dulles is the primary international gateway for the region. Ronald Reagan National is closer to downtown and the monuments but handles mainly domestic flights. Baltimore/Washington International offers additional low‑cost and international options but is farther from central Washington."
      },
      "q13": {
        "question": "How do I get to Tribhuvan Intl Airport from the city center?",
        "answer": "Tribhuvan International Airport is located only about 6 km east of central Kathmandu and the Thamel tourist district, so getting there from the city center is quick and straightforward. Taxis are the most popular option, with prepaid taxi counters inside the terminal building, and ride-share services are also available in the city. Public buses and shuttle services connect the airport to major parts of the Kathmandu Valley via the ring road, and driving is possible with limited parking near the terminals, though traffic congestion on the ring road can slow you down. Taxis or ride-shares are generally fastest and most convenient, while public buses are the cheapest but less comfortable with luggage.",
