        "question": "What is the typical flight duration from Reykjavík to Washington?",
        "answer": "A nonstop flight from Reykjavík (KEF) to Washington Dulles (IAD) typically takes about 6 hours 10 minutes eastbound and roughly 5 hours 50 minutes westbound due to prevailing winds. Icelandair operates the fastest nonstop service on this route. With one stop, common layovers in cities like Boston or New York extend total travel time to around 10 to 12 hours."
      },
      "q1": {
        "question": "Are there any direct flights from Reykjavík to Washington?",
        "answer": "Yes, there are nonstop flights from Reykjavík (KEF) to Washington Dulles (IAD). Icelandair and United both fly the route daily — Icelandair runs two daily departures (around 4:50 PM and 7:50 PM) while United operates one daily departure around 11:30 AM, for a total of 17 weekly nonstops.",

        "answer": "For flights from Reykjavík to Washington, visa requirements depend on your nationality. U.S. citizens do not need a visa to enter the United States. Icelandic citizens can travel visa-free under the Visa Waiver Program but must obtain an ESTA authorization before departure. For the return, U.S. citizens can visit Iceland visa-free for up to 90 days as tourists. Other nationalities should check both U.S. and Icelandic entry rules."

        "answer": "From Washington Dulles (IAD), the Silver Line Express bus connects to the Metrorail Silver Line for $5, which then runs into downtown D.C. (though rail service is unavailable overnight). Taxis, operated by Washington Flyer, are available 24/7 at curbside, while ride-sharing services like Uber and Lyft offer authorized pickup. Shared van shuttles (SuperShuttle, Supreme Shuttle) and multiple rental car companies are also on-site. The Metrorail connection is the most-used budget-friendly option, but taxis and ride-shares are the fastest door-to-door choice.",

        "question": "When is the cheapest time to fly from Reykjavík to Washington?",
        "answer": "September is the cheapest month to fly from Reykjavík to Washington, with average fares around $462, followed by October and November. The most expensive months are June and May, when average prices climb to $757 and $706, respectively.",
        "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. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.",

        "question": "How far in advance should I book tickets from Reykjavík to Washington?",
        "answer": "For flights from Reykjavík to Washington, the optimal booking window is about 11 to 14 weeks before departure, when fares average around $744. The absolute cheapest day to book is 90 days out at $740, while last-minute tickets can climb to over $950. During peak summer or holiday periods, prices tend to rise, so booking even earlier within that window is advisable.",
        "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. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.",

        "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.",

Icelandair operates 10 weekly flights with daily departures at 4:50 PM and 7:50 PM, while United runs 7 weekly flights departing daily at 11:30 AM.

        "question": "Which airport should I use in Washington?",
        "answer": "Dulles is the primary international gateway, located 26 miles west of downtown, with Star Alliance and United hub operations. Reagan National is much closer to the centre and monuments but mainly serves domestic routes, while BWI is farther out and used by low‑cost carriers."
      },
      "q13": {
        "question": "How do I get to Keflavik Intl Airport from the city center?",
        "answer": "From downtown Reykjavík, the most popular and fastest option to reach Keflavík International Airport is the Flybus shuttle, which departs from the central bus station and major hotels, taking about 45 minutes. Public city buses (Strætó route 55) also connect the city center to the airport but are slower and less direct. Taxis and ride‑share services are available but significantly more expensive for the 50‑kilometer journey. Driving yourself is possible and takes roughly the same time as the shuttle, with both short‑term and long‑term parking at the airport.",
