        "question": "What is the typical flight duration from Chicago to San Salvador?",
        "answer": "A nonstop flight from Chicago (ORD) to San Salvador (SAL) typically takes around 4 hours and 45 minutes to 5 hours. With a layover, total travel time generally ranges from 6 to 9 hours, depending on the connection city. The return flight from San Salvador to Chicago often takes slightly longer due to headwinds, averaging about 5 hours to 5 hours and 15 minutes nonstop."

      "q2": {
        "question": "Are there visa requirements to travel from Chicago to San Salvador?",
        "answer": "Yes, visa requirements apply for travel from Chicago to San Salvador. U.S. citizens do not need a visa for stays up to 90 days but must have a passport valid for at least six months beyond the date of entry. Salvadoran nationals do not need a visa to return home. For the return trip, Salvadoran citizens require a visa to enter the United States, while U.S. citizens do not need a visa to return. Other nationalities should check specific visa requirements for both countries."
      },
      "q3": {
        "question": "What are the ground transportation options in San Salvador?",
        "answer": "Ground transportation at San Salvador's El Salvador International Airport (SAL) includes taxis, rideshare apps like Uber, and rental cars, with no direct mass transit rail link to the city center. Taxis are the most commonly used option, offering fixed-rate trips to downtown in about 40 minutes, while rideshare provides a slightly cheaper alternative. Rental car counters are available at the airport for those preferring to drive. For budget travelers, public buses run from the main road outside the terminal but are slower and less comfortable. Overall, taxis are the fastest and most reliable choice for most visitors.",

        "question": "When is the cheapest time to fly from Chicago to San Salvador?",
        "answer": "The cheapest months to fly from Chicago to San Salvador are September, May, and April, with average fares around $479–$481. The most expensive month is December, when average fares climb to about $909, followed by March and July.",
        "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 Chicago to San Salvador?",
        "answer": "For the best fare on flights from Chicago to San Salvador, aim to book 10 to 13 weeks ahead, when prices average around $490. Booking about 80 days out can yield the lowest individual fare near $488, while waiting until the last minute or booking more than 5 months early tends to push prices above $600. Summer and holiday periods usually see higher demand, so securing tickets within that 10–13 week window is even more important for those travel times.",
        "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.",

        "question": "Are overnight (red‑eye) flights available from Chicago to San Salvador?",
        "answer": "No overnight (red‑eye) flights operate from Chicago to San Salvador — neither nonstop nor connecting itineraries with a red‑eye long leg are scheduled on this route.",
        "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.",

      "q7": {
        "question": "Which airlines usually operate this route from Chicago to San Salvador?",
        "answer": "Avianca operates the only nonstop flights from Chicago to San Salvador, with six weekly flights on Tuesdays, Thursdays, and Saturdays departing around 4:10 PM or 5:15 PM. Fares for this nonstop service are not listed, but other carriers may offer connecting routings via their hubs.",
        "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.",

        "question": "If I need a connection, what are common layover cities between Chicago and San Salvador?",
        "answer": "Common layovers include Atlanta, Miami, Houston and Panama City. Atlanta and Miami offer extensive onward connections to San Salvador with short total travel times, while Houston and Panama City provide efficient transfer experiences and visa‑free transit for eligible passengers."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Chicago to San Salvador?",
        "answer": "On‑time performance is generally dependable, but afternoon storms in Chicago can cause delays. Early departures, particularly on Avianca, tend to be more punctual."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to San Salvador?",
        "answer": "November to April is the dry season with sunny days and comfortable temperatures, plus fewer tourists outside of holiday peaks."

      "q11": {
        "question": "What documents should I bring with me to the airport when flying from Chicago to San Salvador?",
        "answer": "Bring a U.S. passport valid for at least six months beyond your stay, proof of onward or return travel, a payment method for baggage and any required vaccination certificates."
      },
      "q12": {
        "question": "Which airport should I use in San Salvador?",
        "answer": "San Salvador has one main international airport, El Salvador International Airport (SAL), located about 40 km southeast of downtown. It serves as the primary gateway, hosting major carriers like Avianca and United Airlines, with connections to North and Central America."
      },
      "q13": {
        "question": "How do I get to Dupage County from the city center?",
        "answer": "DuPage Airport (DPA) is a general aviation facility in West Chicago, about 29 miles west of downtown, and it does not have scheduled commercial passenger service. Since it lacks public transit links like the CTA or Metra, the most practical ways to reach it from the city center are by car or ride‑share (about a 40‑ to 60‑minute drive via I‑290/I‑88), or by taxi; driving yourself is typically the most popular option, with ample on‑site parking available. There are no dedicated shuttle buses, but private car services or limousine companies can be arranged. Costs vary, but a ride‑share or taxi is generally pricier than driving and parking.",
