        "question": "What is the typical flight duration from Washington to San Salvador?",
        "answer": "The flight from Washington Dulles to San Salvador covers about 1,900 miles. Nonstop flights typically take around 4 hours and 28 minutes, while the return leg is about 4 hours and 20 minutes, slightly shorter in that direction. Multiple carriers serve the route, including Avianca, United, Frontier, and N3.",
        "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 Washington to San Salvador?",
        "answer": "Yes, there are nonstop flights from Washington–Dulles to San Salvador on four airlines: Avianca, Volaris El Salvador (N3), United, and Frontier. All four operate daily, giving a combined total of about 154 weekly nonstop departures. Flight time is roughly 4½ hours southbound and about 4 hours 20 minutes on the return.",
        "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 San Salvador?",
        "answer": "From Monseñor Óscar Arnulfo Romero International Airport (SAL), the most reliable and fastest way to reach San Salvador is by taxi or ride-share, with the 42 km trip taking about 30 minutes on a modern four-lane motorway. Authorized taxis are available at the terminal, and ride-hailing apps like Uber operate in the area. There is no direct mass transit link, but public buses run from the highway outside the airport, though they are slower and less comfortable. Car rentals are available from international and local agencies at the airport. Taxis and ride-shares are the most used and recommended options for convenience and safety.",

        "question": "How do I get to Washington Intl Airport from the city center?",
        "answer": "To reach Washington Dulles International Airport (IAD) from downtown Washington, D.C., the Silver Line Express bus provides a nonstop connection to the Wiehle-Reston East Metrorail station, where you can transfer to the Metrorail Silver Line for a direct train ride into the city — this is often the most popular and cost-effective public transit option. Ride‑share services like Uber and Lyft are authorized for pickup, and Washington Flyer taxis are available 24/7 with no reservation needed. Shared van shuttles, such as SuperShuttle, offer door‑to‑door service for groups, and driving yourself is straightforward with on‑site economy parking that includes a free shuttle to the terminal. The Metrorail combination generally offers the best balance of speed and affordability, while a taxi or ride‑share is the fastest door‑to‑door choice.",
