June and December are the most expensive, averaging $1,511.", "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.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Washington to Addis Ababa?", "answer": "For flights from Washington to Addis Ababa, booking 4 to 6 weeks before departure typically yields the best fares, averaging around $1,436. The lowest fares appear about 45 days out at $1,428, while last-minute bookings can exceed $1,600. Although specific summer or holiday patterns aren't detailed, prices tend to be highest right before departure, so securing tickets within that window remains a good rule of thumb.", "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 Addis Ababa?", "answer": "No nonstop red-eye flights operate from Washington Dulles to Addis Ababa, but connecting itineraries whose long leg is an overnight red-eye are available.

Taxis operated by Washington Flyer are available 24/7, while ride‑share services like Uber and Lyft offer convenient door‑to‑terminal pickups.
