        "question": "What is the typical flight duration from Houston to Charleston?",
        "answer": "A nonstop flight from Houston (e.g. IAH) to Charleston (CHS) typically takes about 2 hours 15 minutes. With one stop, depending on the connecting hub, total travel time often ranges from 4 to 6 hours."
      },
      "q1": {
        "question": "Are there any direct flights from Houston to Charleston?",
        "answer": "Yes, Southwest flies nonstop from Houston Hobby to Charleston daily, with up to 23 weekly flights and departures spread from morning through late evening. It's the only airline offering direct service 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.",

        "answer": "From Charleston International Airport (CHS) to the city center, you have several ground transportation options: taxis, ride‑share services like Uber and Lyft, rental cars, and the CARTA public bus. Ride‑share is the most popular choice, with a typical fare around $25–$30 and a drive of about 15–20 minutes to downtown. Taxis are also available at a similar cost, while CARTA’s Route 11 bus is the budget option at $2.00 but takes longer and runs less frequently. Rental cars are convenient if you plan to explore beyond the city, with most major agencies on‑site.",

        "question": "When is the cheapest time to fly from Houston to Charleston?",
        "answer": "The cheapest months to fly from Houston to Charleston are April and May, with average fares around $443–$461, while June and July are the most expensive, averaging $539–$541. March and August fall in between as shoulder months.",
        "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 Charleston?",
        "answer": "For flights from Houston to Charleston, the best time to book is 4–6 weeks before departure, with an average fare around $287. Booking about 100 days out can yield the lowest price at $248, while last-minute purchases (same day) can spike to $592. For summer and holiday periods, it’s wise to book toward the earlier end of that window or slightly beyond, as demand pushes prices higher.",
        "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": "Yes, overnight red-eye flights are available nonstop from Houston (HOU) to Charleston (CHS). Southwest operates three weekly red-eyes on Monday, Thursday, and Friday, departing at 9:10 PM. The flight is short enough that it arrives the same night — not the next morning.",
        "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.",

      "q9": {
        "question": "How reliable are on‑time departures on this route from Houston to Charleston?",
        "answer": "On‑time performance is generally good, but afternoon thunderstorms in Houston can cause delays. Early morning flights on United or Southwest tend to be more reliable."
      },
      "q10": {

      "q13": {
        "question": "How do I get to William P Hobby Airport from the city center?",
        "answer": "From downtown Houston to William P. Hobby Airport (about 7 miles southeast), ride‑share apps and taxis are the most popular and fastest door‑to‑door choices, with taxis available at designated stands. Shared shuttle vans and public bus routes, including Metro bus service, offer the lowest cost but with longer travel times. Driving yourself is also an option, with on‑site parking ranging from hourly to long‑term lots.",

        "question": "Which airline alliances serve flights from Houston to Charleston?",
        "answer": "Southwest Airlines (WN) is the only carrier with nonstop service between Houston Hobby and Charleston, and Southwest does not belong to any of the three global airline alliances. Other alliances may serve the route via connections, but no alliance member operates it nonstop.",
        "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": "What are the best airport lounge options when departing from Houston?",
        "answer": "William P. Hobby Airport (HOU) does not have any traditional airline-branded lounges like a Delta Sky Club, American Admirals Club, or United Club. The only lounge-like option is an XpresSpa location in the Central Concourse near Gate 45, accessible to Priority Pass members (using one lounge visit entitlement for a 25-minute massage chair or similar treatment). It is open daily from 6:00 AM to 9:00 PM, but access is subject to capacity and requires a same-day boarding pass.",
