        "question": "What is the typical flight duration from Washington to Reykjavík?",
        "answer": "A nonstop flight from Washington Dulles (IAD) to Reykjavík (KEF) typically takes about 5 hours 45 minutes to 6 hours. The return flight is usually slightly shorter, around 5 hours 30 minutes. Flights with one stop, often via New York or Boston, generally take 8 to 10 hours total."
      },
      "q1": {
        "question": "Are there any direct flights from Washington to Reykjavík?",
        "answer": "Yes, Icelandair and United both fly non‑stop from Washington Dulles to Reykjavík. Icelandair runs up to 24 weekly flights with multiple daily departures, while United offers one daily flight, and both carriers operate every day of the week.",
        "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 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 Washington to Reykjavík?",
        "answer": "Yes — there are travel‑authorization requirements for a flight from Washington to Reykjavík, depending on your citizenship. If you are a U.S. citizen, you do not need a visa for short visits (up to 90 days) because the U.S. is a visa‑exempt country for Iceland, which is in the Schengen Area. However, from mid‑2025 U.S. citizens will need to obtain an ETIAS travel authorization before travel. If you are an Icelandic or other non‑U.S. national, whether you need a visa or travel authorization for the U.S. depends on your nationality. For the return trip, U.S. visa requirements apply."
      },
      "q4": {
        "question": "When is the cheapest time to fly from Washington to Reykjavík?",
        "answer": "The cheapest time to fly from Washington to Reykjavík is in the fall, especially September when average fares drop to $462, with October and November also offering low prices. Summer is the most expensive season, with June averaging $757 and May around $706, while late summer and winter shoulder months are moderately priced.",
        "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.",

      "q5": {
        "question": "How far in advance should I book tickets from Washington to Reykjavík?",
        "answer": "For the best fare from Washington to Reykjavík, book 11 to 14 weeks ahead, when average prices hover around $744. Summer and holiday periods tend to push the ideal window a bit earlier, so aiming closer to 14 weeks out is wise for peak travel dates.",
        "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.",

        "question": "Are overnight (red‑eye) flights available from Washington to Reykjavík?",
        "answer": "Yes, overnight red-eye flights are available nonstop from Washington Dulles to Reykjavík. Icelandair operates up to 17 weekly red-eyes with departures around 8:30–8:40 PM and a later 11:20 PM departure, while United runs a daily red-eye departing at 10:55 PM. These flights land in the early morning hours, arriving the next day.",
        "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.",

        "question": "If I need a connection, what are common layover cities between Washington and Reykjavík?",
        "answer": "Common layover cities between Washington (IAD) and Reykjavík (KEF) include Boston, New York (JFK/EWR), and Toronto. Boston and New York offer frequent connections and short flight times, minimizing total travel. Toronto provides efficient transfers and, for eligible passengers, visa-free transit through Canada's transit program. These hubs keep the overall journey competitive with nonstop options."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Washington to Reykjavík?",
        "answer": "Reliability is generally good, though afternoon storms at IAD can cause delays. Early departures on Icelandair tend to have higher on‑time rates."

        "question": "Which months have the best weather for traveling to Reykjavík?",

        "question": "What documents should I bring with me to the airport when flying from Washington to Reykjavík?",
        "answer": "Bring a passport valid for at least three months beyond your stay, proof of onward travel, and a payment method for bags; U.S. citizens do not need a visa for Iceland for stays under 90 days."
      },
      "q12": {
        "question": "Which airport should I use in Reykjavík?",
        "answer": "Keflavík International Airport is the only airport serving Reykjavík for international flights. It is located about 50 kilometres southwest of the city centre."
      },
      "q13": {
        "question": "How do I get to Washington Intl Airport from the city center?",
        "answer": "From downtown Washington, D.C., the fastest and most popular way to reach Dulles International Airport is the Silver Line Express bus to the Wiehle-Reston East Metrorail station, where you can transfer to the Silver Line train. Taxis and ride‑share services like Uber and Lyft offer door‑to‑door convenience at a higher cost. Shared‑van shuttles provide a middle ground, while driving yourself is an option with economy parking from $15 per day and a free shuttle to the terminal. The Metrorail combination is usually the quickest during peak traffic hours and the most budget‑friendly.",

Several other nearby hotels provide free shuttle service, though none are directly connected to the single terminal building. Sleeping inside the terminal is discouraged by security, so booking a nearby hotel is the most comfortable option for an overnight stay.",
