        "question": "What is the typical flight duration from Chicago to Delhi?",
        "answer": "A nonstop flight from Chicago (ORD) to Delhi typically takes around 14 to 15 hours eastbound, while the return flight westbound is often about 15 to 16 hours due to prevailing winds. With one stop, common layover cities like London, Frankfurt, or Dubai extend total travel time to roughly 18 to 22 hours, depending on connection duration."
      },
      "q1": {
        "question": "Are there any direct flights from Chicago to Delhi?",
        "answer": "Air India flies nonstop from Chicago O'Hare (ORD) to Delhi four times a week, on Mondays, Wednesdays, Fridays, and Sundays, with a scheduled departure around 1:10 PM. It's the only airline offering a direct flight on this route.",
        "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.",

        "question": "Are there visa requirements to travel from Chicago to Delhi?",
        "answer": "Yes, there are visa requirements for traveling from Chicago to Delhi. U.S. citizens must obtain a visa before traveling to India; they can apply for an e-Visa for tourism, business, or medical visits, or a regular visa for other purposes. Indian citizens do not need a visa to travel to the U.S., but they must have a valid U.S. visa or ESTA authorization if eligible under the Visa Waiver Program (India is not currently a member, so a visa is typically required). For travel from Delhi back to Chicago, Indian citizens must secure a U.S. visa in advance. U.S. citizens returning from India do not need a visa for re-entry."
      },
      "q4": {
        "question": "When is the cheapest time to fly from Chicago to Delhi?",
        "answer": "The cheapest months to fly from Chicago to Delhi are April (around $811), September ($864), and October ($901), with August also in the low season. The most expensive months are June ($1,203), December ($1,152), and July ($1,069), which fall in the high season.",
        "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 Chicago to Delhi?",
        "answer": "For flights from Chicago to Delhi, the optimal booking window is about 10 to 13 weeks before departure, with an average fare around $1004. Bookings made 75 days out can dip as low as $1002, while last-minute purchases at 0 days jump to $1501. For summer (June–August) and holiday periods (December), it's wise to book toward the earlier end of that range to avoid higher prices.",
        "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.",

        "question": "Are overnight (red‑eye) flights available from Chicago to Delhi?",
        "answer": "No nonstop red-eye flights operate from Chicago to Delhi. One connecting itinerary has a red-eye long leg: British Airways via London Heathrow, where the overnight leg LHR→DEL departs at 18:50 and arrives at 08:00 the next morning, after a long layover in London.",
        "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": "Air India operates non-stop flights from Chicago O'Hare to Delhi, with four weekly departures on Monday, Wednesday, Friday, and Sunday, departing around 1:10 PM. Connecting options on this route are available through various airlines, but the schedule data only identifies Air India as the sole non-stop carrier.",

      },
      "q14": {
        "question": "Are there hotels or sleeping facilities at Delhi airport?",

The Holiday Inn Express is located within the airport complex, while Snooze at My Space provides capsule-style pods, both accessible without leaving the terminal. No shuttle is required for these facilities, and they are situated in the transit areas of Terminal 3.",
