        "question": "What is the typical flight duration from Delhi to Houston?",
        "answer": "There are no nonstop flights from Delhi (DEL) to Houston (IAH/HOU). A one-stop itinerary typically takes 19 to 22 hours, with common layovers in Doha, Dubai, or London. The return journey from Houston to Delhi is often about 1–2 hours longer due to prevailing headwinds."
      },
      "q1": {
        "question": "Are there any direct flights from Delhi to Houston?",
        "answer": "There are no nonstop flights from Delhi (DEL) to Houston Hobby (HOU). The shortest connecting routing is typically via Newark (EWR) on United, with a Delhi–Newark leg of about 16 hours 15 minutes on a Boeing 787-9, a layover of roughly 1 hour 40 minutes, and a continuing flight to Houston Hobby of about 3 hours 45 minutes — total travel time around 21–22 hours. Other common connections route through London (LHR), Doha (DOH), or Dubai (DXB) with longer total durations.",
        "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.

Indian citizens need a valid U.S. visa, such as a B1/B2 visitor visa, unless they hold a passport from a Visa Waiver Program country (India is not a member). U.S. citizens traveling to India require a valid Indian visa or an e-Visa for tourism, business, or medical visits. Travelers of other nationalities should check both U.S. and Indian visa requirements based on their citizenship."

        "answer": "William P. Hobby Airport (HOU) offers taxis, ride‑shares (Uber, Lyft), rental cars, shuttles, and limousines/sedans, with no direct mass‑transit rail link to the city center. Ride‑shares and taxis are the fastest and most‑used options for downtown Houston, typically taking 20‑30 minutes. Rental cars are plentiful for those planning to explore beyond the city, while shared shuttles provide a budget‑friendly alternative.",

        "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 fares around $1,090–$1,156. The most expensive months are December, June, and July, where average prices climb to $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 roughly 10 to 13 weeks before departure, with average fares around $1,250. Booking around 85 to 95 days out can drop prices to about $1,236, while last-minute tickets may exceed $1,600. During summer and holiday peaks, it's wise to book on the earlier side of that window, as demand can push fares higher and availability tighter.",
        "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.",

United offers a departure at 11:35 PM arriving Newark at 6:20 AM (with a connection to Houston), while Air India departs at 10:50 PM arriving JFK at 9:40 AM and Air Canada departs at 10:50 PM arriving Toronto at 5:30 AM — both connect onward to Houston. All three red-eye long legs land in the morning hours at their respective hubs.",
        "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 operates the most frequent pattern, connecting via Newark with about 13 daily departures, while British Airways, Air India, and Lufthansa also offer regular one-stop options through London, Frankfurt, or New York JFK. Other carriers like Qatar Airways, Emirates, ITA Airways, and Air Canada appear with fewer daily frequencies, typically via Doha, Dubai, Rome, or Toronto. Median fares are not provided in the schedule data, but United and British Airways dominate the available connections.",

      },
      "q12": {
        "question": "Which airport should I use in Houston?",
        "answer": "Houston has two main airports. George Bush Intercontinental (IAH) is the primary hub for international flights and United Airlines, located 23 miles north of downtown. William P. Hobby (HOU) is closer to downtown and focuses on domestic and Southwest Airlines services."

      "q13": {
        "question": "How do I get to Indira Gandhi Intl Airport from the city center?",
        "answer": "From downtown Delhi, the fastest and most popular way to reach Indira Gandhi International Airport is the Airport Express metro line, which connects New Delhi Railway Station to the airport in about 20 minutes. Taxis and ride‑share services are widely available and offer door‑to‑door convenience at a higher cost, while public buses provide a more economical but slower alternative. Driving is possible with both short‑term and long‑term parking at the airport, though traffic can be unpredictable. For most travelers, the metro offers the best balance of speed and cost.",
