        "question": "What is the typical flight duration from Washington to Reykjavík?",
        "answer": "The flight from Washington, D.C. (IAD) to Reykjavík (KEF) is about 2,790 miles. Nonstop flights typically take 5 hours 55 minutes outbound, while the return leg is longer at 6 hours 40 minutes due to prevailing winds.",
        "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 Reykjavík?",
        "answer": "Yes, two airlines fly nonstop from Washington Dulles to Reykjavík: Icelandair and United, both operating daily. Icelandair runs up to three flights a day with departures around 19:40, 20:30, 20:40, and 23:20, while United has a single daily departure at 22:55. The flight takes about 5 hours 55 minutes eastbound, and several of these departures are red-eyes that arrive the next morning.",
        "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. 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.",

        "question": "What are the ground transportation options in Reykjavík?",
        "answer": "From Keflavík International Airport (KEF), the primary way to reach Reykjavík city center (about 50 km away) is by airport bus, with Flybus and Airport Express offering frequent, reliable service that meets all arriving flights. Taxis are available but very expensive for the long distance, while rental cars are popular for those planning to explore beyond the city. There is no rail link, and ride‑sharing services like Uber are not widely available. The airport bus is the most used option, typically taking 45 minutes to an hour.",

        "answer": "Washington Dulles International Airport is about 26 miles west of downtown Washington, D.C. The most popular and fastest option is the Silver Line Express bus to the Wiehle-Reston East Metrorail station, then taking the Silver Line train into the city; the bus costs $5 each way and runs every 15–20 minutes. Ride-share services like Uber and Lyft offer door-to-door convenience, while Washington Flyer taxis are available 24/7 from the arrivals level. Shared vans like SuperShuttle are a more economical option for groups, and driving yourself with parking in the economy lot is also possible.",
