        "question": "What is the typical flight duration from Washington to Delhi?",
        "answer": "A nonstop flight from Washington Dulles (IAD) to Delhi (DEL) typically takes about 13 hours 45 minutes. With one stop, total travel time often ranges from 15 to 18 hours, depending on the layover city. The return flight from Delhi to Washington is usually about 14 hours 30 minutes nonstop."
      },
      "q1": {
        "question": "Are there any direct flights from Washington to Delhi?",
        "answer": "There are no nonstop flights from Washington Dulles (IAD) to Delhi (DEL). The quickest one‑stop routings take about 21 hours, most commonly connecting via Doha (Qatar Airways), London Heathrow (British Airways), Newark (United), or Abu Dhabi (Etihad), with typical fares around $1,300. Qatar Airways tends to offer the lowest median fare among the main one‑stop carriers at roughly $1,020.",
        "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 and weekly frequencies are summarized 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). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares 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": "Are there visa requirements to travel from Washington to Delhi?",
        "answer": "Yes, there are visa requirements for travel between Washington and Delhi. U.S. citizens need a valid visa to enter India; India offers an e-Visa for tourism and other short stays, which must be obtained before departure. Indian citizens traveling to the United States require a visa, unless they are eligible for the Visa Waiver Program (which India is not a part of), so a visa is necessary. For other nationalities, the requirements depend on their country of citizenship and must be checked with both Indian and U.S. authorities."

        "question": "What are the ground transportation options in Delhi?",
        "answer": "At Delhi's Indira Gandhi International Airport, the fastest and most-used way to reach the city center is the Delhi Metro's Airport Express Line, which runs directly from the terminal to New Delhi Railway Station in about 20 minutes. Prepaid taxis and app-based ride-hailing services like Uber and Ola are widely available and offer door-to-door convenience, though travel time can vary with traffic. Car rentals are present but less common for city transfers, as navigating Delhi's traffic can be challenging for visitors.",

        "question": "When is the cheapest time to fly from Washington to Delhi?",
        "answer": "The cheapest months to fly from Washington to Delhi are September, April, and August, with average fares around $813, $826, and $853 respectively. The most expensive months are December, June, and July, with average fares climbing to $1,181, $1,131, and $1,049. Low season (September, April, August, October) offers the best value, while high season (January, July, June, December) is priciest.",
        "methodology": "This 'good deal' estimate shows a representative best price for each departure date across roughly a 12-month window (about 3 months back and 9 months forward). It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise.",

      "q5": {
        "question": "How far in advance should I book tickets from Washington to Delhi?",
        "answer": "For the best fare from Washington to Delhi, aim to book 9 to 12 weeks ahead, when the average price is around $978. Booking about 65 days out can yield the lowest fare, while last-minute bookings cost significantly more. During peak summer and holiday periods, demand is higher, so it's wise to book a few weeks earlier than the typical window to secure better rates.",
        "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row.",

        "answer": "Red-eye options from Washington (IAD) to Delhi (DEL) are available only as connecting itineraries whose long leg is an overnight flight. For example, SWISS operates an overnight leg from IAD to Zurich departing at 20:20 and arriving at 10:25, connecting onward to Delhi; KLM offers an overnight leg from Amsterdam to Delhi departing at 16:45 and arriving at 04:15 (early hours, next day), and ITA Airways runs an overnight leg from IAD to Rome departing at 16:30 and arriving at 07:15, with onward connections to Delhi.",
        "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.",

Ride‑share services like Uber and Lyft, and Washington Flyer taxis, offer direct door‑to‑door trips. Shared‑van shuttles (SuperShuttle and Supreme Shuttle) are also available. Driving and parking at the airport is an option, with economy lots and a free shuttle to the terminal. The Metrorail is often the most popular and cost‑effective choice, while ride‑share or a taxi is the fastest.",

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.",
