        "question": "What is the typical flight duration from Houston to Delhi?",
        "answer": "There are no nonstop flights from Houston (IAH) to Delhi (DEL). A one‑stop itinerary typically takes 18 to 22 hours, depending on the connection. Common layover cities include Doha (Qatar Airways), Dubai (Emirates), Istanbul (Turkish Airlines), and Frankfurt (Lufthansa/United). Eastbound flights (Houston to Delhi) are often slightly shorter than westbound returns due to prevailing winds; the return can be 1–2 hours longer. Airlines like Emirates and Qatar Airways often operate some of the fastest total travel times on this route."

      "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 option in the schedule data is via Newark (EWR) on United, with a total journey time around 18.5 hours, or via Doha (DOH) on Qatar Airways at about 18.5–19 hours.",
        "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. 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. 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": "Are there visa requirements to travel from Houston to Delhi?",
        "answer": "Yes, there are visa requirements. For U.S. citizens traveling to India, a visa is required. India offers an e-Visa for tourism, business, or medical visits, which must be obtained online prior to travel. For Indian citizens traveling to Houston, a visa is generally required unless they hold a U.S. passport or permanent residency. Indian nationals need a valid U.S. visa, such as a B1/B2 visitor visa, or must qualify under the Visa Waiver Program (which India is not part of) and have an approved ESTA. Always check the latest rules before booking."

        "question": "What are the ground transportation options in Delhi?",
        "answer": "Indira Gandhi International Airport in Delhi offers several ground transportation options to the city center. The Delhi Metro’s Airport Express Line is the fastest and most reliable, reaching New Delhi Station in about twenty minutes. Regular taxis and app-based ride services like Uber and Ola are widely available and offer door-to-door convenience, taking forty-five to sixty minutes depending on traffic. Pre-paid taxi counters inside the terminal provide fixed fares. Buses run by DTC and private operators are cheaper but slower and less comfortable. Car rentals are available but not recommended for navigating Delhi’s chaotic traffic. The Airport Express Metro is the most used option due to its speed and efficiency."

      "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 $1065), February ($1094), and October ($1117), with the low season in September, February, October, and August. The most expensive months are December (average $1469), June ($1420), and May ($1300), falling in the high season along with April.",
        "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.",

        "question": "How far in advance should I book tickets from Houston to Delhi?",
        "answer": "For the Houston to Delhi route, the optimal booking window is roughly 21 to 24 weeks (about 5 to 6 months) before departure, with average fares around $1238 — booking about 155 days out can yield the lowest price near $1216. During peak summer (June–August) and the winter holiday season (December), demand pushes fares higher, so aim for the earlier end of that window or even 6–7 months ahead.",
        "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": "There are no nonstop red-eye flights from Houston (IAH) to Delhi (DEL), but connecting itineraries whose long leg is an overnight flight are available. For example, Air France offers an overnight leg departing IAH around 5:05 PM arriving Paris (CDG) at 9:25 AM next day, and United has overnight legs to Frankfurt (departing around 6:20 PM, arriving 11:15 AM) and Munich (departing around 4:40 PM, arriving 9:45 AM), each connecting onward to Delhi.",

Doha and Dubai offer one-stop itineraries with strong Gulf carrier networks and efficient hubs, often providing competitive total travel times. London and Frankfurt are major European gateways with broad transatlantic and Asian connections, though they may require longer routings. Doha and Dubai also feature visa-free transit for many nationalities, simplifying connections."

        "question": "How reliable are on‑time departures on this route from Houston to Delhi?",
        "answer": "On-time performance is generally reliable but can be affected by afternoon thunderstorms in Houston, especially in summer. Early morning departures, such as those on United or Air India, tend to have better punctuality. Consider flights before 10 AM for higher odds of an on-time departure."

      "q12": {
        "question": "Which airport should I use in Delhi?",
        "answer": "Delhi's Indira Gandhi International Airport is the primary airport serving the city, handling all international flights and most domestic services. It is located about 16 km southwest of the city center, with good metro and taxi connectivity to downtown and major attractions. The airport is a hub for Air India and IndiGo, and serves as a base for many international carriers across alliances. For regional or low-cost domestic flights, Hindon Airport near Ghaziabad is used by some carriers, but it is farther from central Delhi and not practical for international arrivals."

      "q13": {
        "question": "How do I get to George Bush Intercontinental Airport from the city center?",
        "answer": "From downtown Houston to Bush Intercontinental (IAH), the METRO 102 bus takes about 50–70 min and is the lowest-cost option. Rideshares and taxis are the fastest and most popular, taking 20–35 min in light traffic but costing significantly more. Shared shuttles offer a middle-ground price. Parking at IAH is widely available but is the most expensive choice for longer trips."
