        "question": "What is the typical flight duration from Dallas to San Salvador?",
        "answer": "A nonstop flight from Dallas/Fort Worth (DFW) to San Salvador (SAL) typically takes about 3 hours 30 minutes. Return flights with a tailwind can be slightly shorter, usually around 3 hours 15 minutes. With one stop, common layovers include Houston (IAH) or Miami (MIA), bringing total travel time to roughly 6 to 8 hours. American Airlines operates the only nonstop service on this route."

        "question": "Are there any direct flights from Dallas to San Salvador?",

        "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. 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": "Are there visa requirements to travel from Dallas to San Salvador?",
        "answer": "Yes, visa requirements apply for travel from Dallas, Texas (DFW) to San Salvador, El Salvador (SAL). U.S. citizens do not need a visa for tourism or business stays up to 90 days but must obtain a visa for longer stays or other purposes. Non-U.S. citizens should check El Salvador's visa policy based on their nationality. Travelers from many countries, including most in the Americas and Western Europe, do not require a visa for short visits. All visitors must have a passport valid for at least six months from the date of entry. Upon arrival, you may need to show proof of onward travel and may be subject to a tourist card fee. For the return from San Salvador to Dallas, U.S. visa requirements apply for non-U.S. citizens, including ESTA for Visa Waiver Program nationals."

        "question": "What are the ground transportation options in San Salvador?",
        "answer": "San Salvador’s main airport, Monseñor Óscar Arnulfo Romero International Airport (SAL), is about 40 kilometers from the city center. There is no direct mass transit like trains or metro. The most popular options are prepaid taxis and ride-share services like Uber, which offer safe, fixed-price rides to the city in about 45 to 60 minutes depending on traffic. Public buses are available but are slower, crowded, and not recommended for visitors carrying luggage. Car rentals are possible at the airport but driving can be challenging due to traffic and road conditions. Shuttle services are also offered by some hotels and tour operators. Most travelers use prepaid taxis or ride-share for their convenience and security."

        "question": "When is the cheapest time to fly from Dallas to San Salvador?",
        "answer": "The cheapest months to fly from Dallas to San Salvador are April (around $470), May ($491), and September ($514), with March also in the low season. The most expensive months are December (around $807), November ($629), and February ($606), which fall in the high season.",
        "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 Dallas to San Salvador?",
        "answer": "For the best fare from Dallas (DFW) to San Salvador (SAL), book roughly 19 to 22 weeks ahead, when prices average around $607. For summer and holiday travel, booking even earlier is wise, as last-minute tickets can jump to $766 or more.",
        "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.",

        "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.",
