        "question": "What is the typical flight duration from Delhi to Washington?",
        "answer": "The flight from Delhi to Washington covers about 7,490 miles. There are no scheduled nonstop flights on this route, so the journey requires a connection; approximate total travel time is typically 18 to 22 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 is connected to downtown Washington, D.C. by the Metrorail Silver Line, which runs from the airport's dedicated station via an indoor pedestrian tunnel with moving sidewalks. Taxis, ride-share services, and car rentals are also available at the airport. The Silver Line Metrorail is the most-used public transit option for reaching the city center, offering a direct, all-weather connection. For speed, a taxi or ride-share can be faster outside of peak traffic, but Metrorail is generally the most reliable and affordable choice for most travelers.",

        "answer": "No nonstop red‑eyes operate from Delhi to Washington, but one‑stop itineraries whose long leg is an overnight flight are available. Air Canada offers a red‑eye departing Delhi at 22:50 and arriving in Toronto at 05:30, connecting onward to Washington Dulles (1h50m layover); United has a red‑eye departing Delhi at 23:35 and arriving in Newark at 06:20, with a connection to Dulles (1h55m layover). Ethiopian Airlines also operates a red‑eye from Addis Ababa to Dulles (departing 22:50, arriving 08:55), though the layover in Addis is long at about 9 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 airlines usually operate this route from Delhi to Washington?",
        "answer": "There is no nonstop service between Delhi and Washington Dulles; travelers connect through hubs like Newark, Doha, Paris, Abu Dhabi, New York JFK, Dubai, Frankfurt, Zurich, Toronto, Istanbul, or Rome. United offers the most frequent one-stop routing via Newark with 10 daily connections, while Qatar Airways (via Doha), Air France (via Paris), Etihad (via Abu Dhabi), and American (via JFK) each operate around 4 daily connections. Emirates, Lufthansa, SWISS, Air India, Air Canada, and Turkish Airlines also serve the route with fewer daily frequencies.",
        "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. Where a typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.",

        "answer": "Common layovers include Dubai, Doha, London, and Frankfurt. Dubai and Doha offer extensive connections and efficient transfers, while London and Frankfurt provide broad European networks and smooth transit for eligible passengers. US citizens and many others can transit visa-free in the UK and Schengen area under certain conditions."

      },
      "q12": {
        "question": "Which airport should I use in Washington?",
        "answer": "Dulles International is the primary international gateway for Washington, located about 26 miles west of downtown. Reagan National is much closer to the city centre and the National Mall but mainly handles domestic flights with limited international service. Baltimore/Washington International is farther northeast, often used for low-cost carriers and additional domestic options."

      "q13": {
        "question": "How do I get to Indira Gandhi Intl Airport from the city center?",
        "answer": "Getting to Indira Gandhi International Airport from central Delhi is easiest by ride-share or taxi, which are the most popular and fastest options, especially with apps like Uber and Ola, though costs vary and can be higher than public transport. The Delhi Metro's Airport Express Line is a quick and inexpensive public transport choice, connecting New Delhi Railway Station to the airport in about 20 minutes, and DTC buses also run to the airport but can be slower due to traffic. Auto-rickshaws are cheaper than taxis but require haggling, while driving yourself means dealing with heavy congestion and paid parking at the airport.",
