(IAD) to Reykjavík (KEF) is about 2,790 miles and typically takes 5 hours 55 minutes. The return flight is longer, at about 6 hours 40 minutes, due to prevailing headwinds.

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.

Taxis are available but expensive, often costing significantly more than the bus; there is no train or metro link.

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.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Washington to Reykjavík?", "answer": "For flights from Washington to Reykjavík, the best fares usually appear when booking 11 to 14 weeks ahead, with an average price around $740. The absolute lowest price in the data was $735 about 85 days before departure, while last-minute bookings (0–5 days out) can spike to over $950. During peak summer months (June–August) and holiday periods, you may want to book even earlier—closer to 16–20 weeks out—to secure better availability and avoid higher fares.", "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.", "toolsUsed": ["booking_timing"]}, "q6": {"question": "Are overnight (red‑eye) flights available from Washington to Reykjavík?", "answer": "Overnight red‑eye flights are available nonstop from Washington Dulles (IAD) to Reykjavík (KEF).

Taxis operated by Washington Flyer are available 24/7 from the terminal, offering a direct but relatively expensive ride, while ride‑share services like Uber and Lyft provide a similar door‑to‑door alternative at a mid‑range cost. Shared‑van services such as SuperShuttle offer a budget‑friendly group option, and driving yourself is possible with economical long‑term parking from $15 per day, though it is the slowest choice given the 26‑mile distance from downtown.
