        "question": "What is the typical flight duration from Chicago to San Salvador?",
        "answer": "A direct flight from Chicago O'Hare (ORD) to San Salvador (SAL) typically takes about 4 hours 40 minutes to 5 hours, with the return being slightly shorter at around 4 hours 20–30 minutes. Flights with one stop (commonly in Houston, Miami, or Atlanta) range from 7 to 10 hours total, depending on layover duration."

        "question": "Are there any direct flights from Chicago to San Salvador?",
        "answer": "Yes, Avianca (AV) flies nonstop from Chicago O'Hare (ORD) to San Salvador (SAL) with 6 weekly flights on Tuesdays, Thursdays, and Saturdays, typically departing in the late afternoon. It is not daily — there is no service on Monday, Wednesday, Friday, or Sunday.",
        "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.",

        "question": "Are there visa requirements to travel from Chicago to San Salvador?",
        "answer": "Yes, visa requirements apply for travel from Chicago (USA) to San Salvador (El Salvador). U.S. citizens generally do not need a visa for tourist or business visits up to 90 days; a valid passport is required, and a tourist card must be purchased on arrival for about $12. Nationals of El Salvador do not need a visa to enter their own country. Other nationalities should check with Salvadoran authorities, as requirements vary. For travel from El Salvador back to Chicago, Salvadoran citizens need a U.S. visa unless they hold a valid ESTA under the Visa Waiver Program."

        "question": "When is the cheapest time to fly from Chicago to San Salvador?",
        "answer": "Based on seasonal price data for flights from Chicago to San Salvador, the cheapest months are April (average $449), May ($481), and September ($483), while the most expensive are December (average $922), November ($612), and July ($612).",
        "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 Chicago to San Salvador?",
        "answer": "For the best fares from Chicago (ORD) to San Salvador (SAL), aim to book 6 to 9 weeks before departure, when average prices are around $489, with the absolute cheapest single day about 45 days out at $483. Prices climb noticeably closer to departure, reaching $579 for last-minute bookings. During peak summer or holiday periods, booking even earlier—10 to 12 weeks ahead—is advisable to avoid steep markups.",
        "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.",

A connecting overnight option exists via Bogotá on Avianca, with the long red-eye leg ORD→BOG departing around 11:20 PM and arriving at 5:30 AM, followed by a roughly 3.5-hour layover before the short hop to San Salvador.",
        "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.",
