        "question": "What is the typical flight duration from Washington to Kathmandu?",
        "answer": "Washington (IAD) to Kathmandu (KTM) is about 7,700 miles. There is no scheduled nonstop service on this route, so a connection is required; total journey time is typically 18 to 24 hours depending on layover duration and routing.",
        "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 Washington to Kathmandu?",
        "answer": "There are no nonstop flights from Washington Dulles to Kathmandu. The shortest one-stop routings connect via Doha (Qatar Airways), Istanbul (Turkish Airlines), Dubai (Emirates), or Abu Dhabi (Etihad), and take around 27 hours total. Fares for these one-stop itineraries typically run from about $1,350 to $1,950, with Emirates offering the lowest median fare around $1,718.",
        "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. 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.",

        "question": "What are the ground transportation options in Kathmandu?",
        "answer": "From Tribhuvan International Airport, prepaid taxis are available at the terminal and are the most common way to reach the city center, about 6 km to Thamel. Ride-share services like Pathao and inDrive operate in Kathmandu and are often cheaper than taxis, though availability can be spotty at the airport. A public bus serves the airport road but is slow, crowded, and not recommended with luggage. Car rentals exist but are uncommon for tourists due to chaotic traffic and lack of parking. The fastest practical option is a taxi or ride-share, but prepaid taxis are the most used modality.",

The cheapest months overall are September ($420), October ($425), and February ($449), while the most expensive stretch is late December, averaging $563. December, July, and June are the priciest months on the route.",
        "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.",

Other one-stop patterns include a connection via Abu Dhabi on Etihad. These carriers offer the main scheduled connections from Washington to Kathmandu.",

These cities offer broad connections on Emirates, Qatar Airways, and Turkish Airlines respectively, with efficient one-stop routings that keep total travel time competitive. All three allow visa-free transit for many passport holders, simplifying the journey."

        "question": "Which airport should I use in Kathmandu?",
        "answer": "Kathmandu has one commercial airport, Tribhuvan International Airport, which serves all international and domestic flights. It is located about 6 km east of the city centre, providing easy access to Thamel and major attractions."
      },
      "q13": {
        "question": "How do I get to Washington Intl Airport from the city center?",
        "answer": "From downtown Washington, the Silver Line of the Metrorail goes directly to Dulles International Airport, connecting to the main terminal via an indoor pedestrian tunnel with moving sidewalks. Ride-share services like Uber or Lyft and taxis are common and generally the fastest door-to-door option, though they cost more than public transit. Driving is also possible, with parking garages adjacent to the terminal, but traffic on the Dulles Access Road can add time. The Metrorail is the most popular budget-friendly choice, while ride-share or taxi is fastest.",
