        "question": "What is the typical flight duration from Houston to Delhi?",
        "answer": "There are no nonstop flights from Houston (IAH) to Delhi (DEL). The fastest one-stop itineraries, often via Doha, Dubai, or London, take about 17 to 19 hours. Return flights from Delhi to Houston are typically 1–2 hours longer due to prevailing headwinds."
      },
      "q1": {
        "question": "Are there any direct flights from Houston to Delhi?",
        "answer": "There are no nonstop flights from Houston (IAH) to Delhi (DEL). The shortest connecting routings are one-stop itineraries typically taking about 21½ hours, most commonly via Doha (Qatar Airways), London Heathrow (British Airways), or Newark (United). Qatar Airways tends to offer the lowest median fare on this route at around $1,166, while one-stop tickets start as low as $881.",
        "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 Houston to Delhi?",
        "answer": "Yes, visa requirements apply for travel from Houston to Delhi. U.S. citizens need a valid visa or an e-Visa to enter India. Indian citizens do not need a visa to enter the U.S. if they hold a valid U.S. visa or are otherwise eligible for entry, but they must have the appropriate documentation. For the return from Delhi to Houston, U.S. citizens can re-enter the U.S. with a valid passport, while Indian citizens need a valid U.S. visa or ESTA if eligible. Always check the latest requirements before travel."
      },
      "q4": {
        "question": "When is the cheapest time to fly from Houston to Delhi?",
        "answer": "The cheapest months to fly from Houston to Delhi are September (average $1,090), October ($1,135), and August ($1,156), with the overall low season spanning August through November. The most expensive months are December ($1,477), June ($1,446), and July ($1,339), making the high season May, July, June, and December.",
        "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 Houston to Delhi?",
        "answer": "For the best fare from Houston to Delhi, aim to book about 10 to 13 weeks before departure, with prices averaging around $1,250 in that window. Booking too close to travel can push fares above $1,600, while very early booking (more than 20 weeks out) also tends to be pricier — during peak summer or holiday periods, expect the optimal window to shift slightly earlier and base fares to be higher overall.",
        "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 Houston to Delhi?",
        "answer": "No nonstop red-eye flights operate from Houston (IAH) to Delhi (DEL), but one-stop connecting itineraries whose long leg is an overnight flight are available. United offers a red-eye from IAH to Frankfurt departing at 6:20 PM and arriving at 11:15 AM (connecting to Lufthansa with a 2h05m layover), and another via Munich departing at 4:40 PM and arriving at 9:45 AM (connecting to Lufthansa with a 3h10m layover). Both long-haul legs arrive in the morning hours, so they land the next morning local time.",
        "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 Houston to Delhi?",
        "answer": "There are no nonstop flights from Houston (IAH) to Delhi (DEL). The most common one-stop routings are operated by United (via Newark, up to 7 daily connections), Air Canada (via Toronto, 4 daily), Qatar Airways (via Doha, 4 daily), and British Airways (via London, 3 daily). Other carriers like KLM, Emirates, Lufthansa, Air France, and Air India also offer connecting service, typically 2 daily each. Per‑carrier fares are not provided in the schedule data, so I cannot quote median fares for these airlines.",

        "question": "If I need a connection, what are common layover cities between Houston and Delhi?",
        "answer": "Common layover cities for Houston to Delhi include Doha, Dubai, London, and Frankfurt. Doha and Dubai offer efficient transfers and broad connections across the Middle East and Asia, often with competitive total travel times. London and Frankfurt serve as major European hubs with extensive onward flights and can be convenient for breaking up the long journey, though they may require a transit visa depending on your nationality."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Houston to Delhi?",
        "answer": "On-time performance is generally reliable, though long-haul routes can face cumulative delays. Morning departures, particularly on Emirates via Dubai, tend to have better punctuality."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to Delhi?",
        "answer": "October to March offers pleasant temperatures and low humidity, avoiding the extreme heat and monsoon crowds."

      "q11": {
        "question": "What documents should I bring with me to the airport when flying from Houston to Delhi?",
        "answer": "Bring your passport valid for at least six months, a valid Indian visa or e-Visa, proof of onward or return travel, a payment method for baggage, and any required vaccination certificates such as for yellow fever if applicable."
      },
      "q12": {
        "question": "Which airport should I use in Delhi?",
        "answer": "Indira Gandhi International Airport is Delhi's only commercial airport. It serves all domestic and international flights and is located about 16 km southwest of the city centre, with metro and taxi connections to major attractions."
      },
      "q13": {
        "question": "How do I get to George Bush Intercontinental Airport from the city center?",
        "answer": "From downtown Houston, the most popular and fastest option is a taxi or ride‑share, taking about 25 minutes via I‑45 or the Hardy Toll Road. Public transit is limited—Metro bus 102 serves IAH but requires a transfer and takes over an hour. Shared shuttle vans and hotel shuttles are also available from baggage claim. Driving and parking is straightforward, with on‑airport garages and economy lots connected by shuttle, though costs are higher for close‑in parking.",
