        "question": "What is the typical flight duration from Chicago to Charleston?",
        "answer": "The flight from Chicago to Charleston is about 745 miles, with a typical nonstop duration of 2 hours and 14 minutes. The return flight averages 2 hours and 29 minutes, so the westbound leg is about 15 minutes longer.",
        "methodology": "Flight times and distances come 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

      "q1": {
        "question": "Are there any direct flights from Chicago to Charleston?",
        "answer": "Yes, nonstop flights from Chicago to Charleston run daily on American, United, and Southwest. American and United fly from O'Hare with up to 85 weekly departures combined (American also has a less-frequent mainline schedule on Monday, Thursday, Friday, Saturday, and Sunday), while Southwest serves Midway with 35 weekly flights. The typical flight time is about 2 hours 14 minutes.",
        "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, flight times and distances for this route come 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). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "question": "What are the ground transportation options in Charleston?",
        "answer": "Ground transportation at Charleston International Airport (CHS) includes ride sharing (Uber, Lyft, KreweCar), taxis with a $17 minimum fare, CARTA public bus service to downtown Charleston, hotel shuttles, and multiple rental car companies. Ride sharing and taxis are the fastest options for most travelers, with dedicated pickup areas right outside baggage claim. The CARTA bus is the most budget-friendly, offering scheduled service to downtown and the Tanger Outlet Center. Rental cars are convenient for exploring the wider Charleston area, with desks located at the end of the terminal. Ride sharing tends to be the most used option due to its balance of speed and cost.",

        "question": "When is the cheapest time to fly from Chicago to Charleston?",
        "answer": "Average fares from Chicago to Charleston bottom out around $329 in late January, the cheapest stretch of the year. The cheapest months overall are September ($330) and January ($332), while the most expensive period is late December, when average fares climb to about $429. December is the priciest month at $413 on average.",
        "methodology": "Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.",

      "q5": {
        "question": "How far in advance should I book tickets from Chicago to Charleston?",
        "answer": "For Chicago to Charleston, booking 4-7 weeks before departure typically gets the best fares, averaging around $285. The absolute lowest price appears about 35 days out at roughly $283, while prices climb notably if you book more than 3 months ahead or wait until the final week. For summer and holiday travel, you'll want to book earlier within that window or even slightly before it, since peak demand pushes fares up faster.",
        "methodology": "Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.",

Southwest operates nonstop red-eyes from Chicago Midway (MDW) to Charleston (CHS) four times a week — on Monday, Thursday, Friday, and Sunday — with departures around 9:00 PM to 9:50 PM. These flights depart late evening and land before midnight, arriving the same night.",
        "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.",

        "answer": "Common layover cities for this domestic route include Atlanta, Charlotte, and Dallas, which offer frequent connections and efficient transfers. Atlanta and Charlotte are major hubs for Delta and American Airlines respectively, providing broad domestic networks and short connecting times. Dallas can also be competitive, especially on American Airlines itineraries. Visa‑free transit is irrelevant for this domestic route."

      "q9": {
        "question": "How reliable are on‑time arrivals on this route from Chicago to Charleston?",
        "answer": "On the Chicago to Charleston route, arrival on-time performance ranges from 77.4% to 91.2% depending on the carrier. Republic Airways (operating for American and United) leads at 91.2%, followed by American at 79.2%, United at 78.7%, Envoy (for American) at 77.5%, and Southwest at 77.4%. Cancellation rates are low, from 0.0% for American to 2.0% for Envoy.",
        "methodology": "On-time arrival and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; a flight counts as on time when it arrives within 15 minutes of schedule. Carriers are ranked by arrival on-time rate on this route, and the carrier list itself comes 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).",

Major carriers include Delta, American, United, and Southwest, with a mix of domestic routes and a few seasonal international flights."

      "q13": {
        "question": "How do I get to Dupage County from the city center?",
        "answer": "From downtown Chicago, the CTA Blue Line 'L' train is the fastest and most popular option, running directly from the Loop to O'Hare in about 40 minutes with 24-hour service and relatively low cost. Metra's North Central Service also connects Union Station to O'Hare via the O'Hare Transfer Station on weekdays, while Pace suburban buses serve the airport from nearby suburbs. Taxis and ride-share services offer door-to-door convenience at a higher price, and driving takes about 30–45 minutes via the Kennedy Expressway with parking available in the Main Garage or economy lots. For most travelers, the Blue Line is the best balance of speed, cost, and reliability.",

        "question": "What aircraft are typically used on flights from Chicago to Charleston?",
        "answer": "Southwest Airlines flies the most from Chicago to Charleston, using Boeing 737 family aircraft including the Boeing 737-700. United Airlines flies Airbus A320 family aircraft, specifically the Airbus A320, while American Airlines operates Airbus A319s and Envoy Air operates Embraer E175s on behalf of American. Republic Airways, flying for American and United, uses Embraer E175 aircraft.",
        "methodology": "Aircraft types come 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). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.",
