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 Baltimore to San Francisco?", "answer": "For flights from Baltimore to San Francisco, the best fares are typically found when booking 4 to 6 weeks ahead, with an average price around $293. The absolute cheapest day is about 45 days before departure at $282, while last-minute bookings can cost $466 or more. During peak summer and holidays, prices tend to be higher overall, so aiming for that 4-6 week window remains a solid strategy, though booking a bit earlier—around 6-8 weeks out—may help avoid holiday spikes.", "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 Baltimore to San Francisco?", "answer": "No nonstop red‑eye flights operate from Baltimore to San Francisco, but connecting itineraries whose long overnight leg is a red‑eye are available.
