        "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.",

        "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.",

Entry is permitted visa-free for stays of up to 180 days.\n\nThis is general guidance to help you plan, not official immigration advice — entry rules can change and can depend on your nationality and circumstances, so please confirm the current requirements with the relevant embassy or official government source before you travel.",

Ride-share apps like Uber are available but less common than taxis, and car rentals are offered at the airport though driving yourself is not the norm for visitors. There is no rail link to the airport, and public buses exist but are generally slower, less comfortable, and not recommended with luggage. Taxis and private shuttles are the most-used and reliable choice for travelers heading to the city center.",

Ride-share services like Uber and Lyft, taxis, and shuttle buses also serve the airport, while drivers can park on-site in garages or economy lots. The Silver Line is the most popular and cost-effective option for many travelers, though taxis and ride-shares are faster for door-to-door service at a higher cost.",

        "question": "What aircraft are typically used on flights from Washington to San Salvador?",
        "answer": "Avianca operates the most flights from Washington to San Salvador, using Airbus A320neo and Airbus A320 aircraft. Volaris El Salvador flies Airbus A320s, United uses Boeing 737 family jets, and Frontier operates Airbus A320neos on this route.",
        "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.",

        "question": "Which airline alliances serve flights from Washington to San Salvador?",
        "answer": "Nonstop service from Washington Dulles to San Salvador is operated by Avianca, Volaris El Salvador, United, and Frontier. Avianca and United are both Star Alliance members, so Star Alliance is the only alliance with nonstop representation on this route. Volaris El Salvador and Frontier are unaligned carriers; other alliances may offer connecting itineraries.",
        "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.",
