        "question": "What is the typical flight duration from Delhi to Houston?",
        "answer": "A nonstop flight from Delhi (DEL) to Houston (IAH) is not available; most itineraries involve one or two stops. Common one‑stop routes via Doha, Dubai, or London typically take 20 to 24 hours total travel time, while the return from Houston to Delhi is often slightly longer, around 22 to 26 hours due to prevailing winds. Airlines like Qatar Airways and Emirates frequently offer competitive connection times."
      },
      "q1": {
        "question": "Are there any direct flights from Delhi to Houston?",
        "answer": "There are no nonstop flights from Delhi (DEL) to Houston (IAH). The shortest one-stop option is typically via Newark (EWR) on United, taking about 15 hours 15 minutes total with a roughly 4-hour layover, or via London Heathrow (LHR) on British Airways or Air India at around 15–16 hours. Fares for one-stop itineraries start around $954, with United and British Airways being the most frequent carriers 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. Aircraft types are taken from the equipment each operating carrier schedules on this route, drawn from published airline timetables and airline equipment schedules in our flight-schedule database. They describe typical scheduled aircraft and can vary with seasonal or day-of-week assignments and last-minute equipment swaps. 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 Delhi to Houston?",
        "answer": "Yes, visa requirements apply for travel from Delhi to Houston depending on your nationality. If you are an Indian citizen, you must obtain a U.S. visa (such as a B1/B2 visitor visa) before travel; you cannot use ESTA. If you are a U.S. citizen, you need a valid Indian visa or an e-Visa to enter India, which must be obtained before departure from the U.S. For other nationalities, check both U.S. entry rules (visa or ESTA) and Indian entry rules (visa or e-Visa) based on your passport."

        "question": "What are the ground transportation options in Houston?",
        "answer": "From George Bush Intercontinental Airport (IAH), you can get to downtown Houston via taxi, ride apps (Uber/Lyft), rental cars, shuttles, limousines, or public transit. The airport is about 23 miles north of downtown, with direct access to major highways like I-45 and the Hardy Toll Road. Ride apps and taxis are widely available 24/7 from curbsides at Terminals A, C, and E, offering the fastest door-to-door trips in roughly 30–45 minutes depending on traffic. The most-used option tends to be ride-hailing services due to convenience, though rental cars are popular for longer stays, with a consolidated Rental Car Center just a short shuttle ride from the terminals. Public transit via bus routes is available but generally slower and less direct than private options.",

        "question": "When is the cheapest time to fly from Delhi to Houston?",
        "answer": "The cheapest months to fly from Delhi to Houston are September, October, and August, with average round-trip fares around $1,090–$1,156. The most expensive months are December, June, and July, where average prices climb to roughly $1,339–$1,477.",
        "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. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.",

      "q5": {
        "question": "How far in advance should I book tickets from Delhi to Houston?",
        "answer": "For flights from Delhi to Houston, the optimal booking window is about 10 to 13 weeks before departure, with an average fare around $1,250. Booking around 90 days out can secure the lowest prices near $1,235, while last-minute tickets can exceed $1,600. During summer and holiday periods, fares tend to rise earlier, so it's wise to book a few weeks sooner than the typical window.",
        "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. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.",

Air India offers a red-eye from Delhi departing at 22:50 and arriving at New York JFK at 09:40, connecting to JetBlue for the onward leg. United also operates a red-eye from Delhi departing at 23:35 and arriving at Newark at 06:20, with a connecting United flight to Houston.",
        "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.",

United Airlines offers the most frequent one-stop connections via Newark (about 12 daily), while Air India connects through London Heathrow or New York JFK. British Airways routes via London Heathrow, Emirates via Dubai, and Qatar Airways via Doha, each with a few daily options. Lufthansa also operates a connection through Frankfurt.

        "question": "How reliable are on‑time departures on this route from Delhi to Houston?",

      },
      "q12": {
        "question": "Which airport should I use in Houston?",
        "answer": "Houston has two airports. George Bush Intercontinental is the main international gateway, located about 23 miles north of downtown, and serves as a major hub for United Airlines and Star Alliance. William P. Hobby Airport is closer to downtown, about 7 miles southeast, and primarily handles domestic flights, including Southwest Airlines' operations."

        "answer": "To reach Indira Gandhi International Airport (DEL) from central Delhi, the fastest and most popular option is the Delhi Metro's Airport Express Line, which connects New Delhi Railway Station to the airport in about 20 minutes. Pre-paid taxis and ride‑share services like Uber and Ola are widely available and offer door‑to‑door convenience, though travel time varies with traffic. Public buses operated by DTC also serve the airport, but they are slower and less comfortable. Driving and parking at the airport is possible, with both short‑term and long‑term lots available, but costs can add up over extended stays.",
