Rideshare services like Uber and Lyft pick up on the third floor of the parking garage, while metered taxis are available on the north and south curbs of the same level. Rental cars are off-site with free shuttle buses, and public buses stop near the light rail station on International Boulevard.

The low season includes March, May, and September, and the high season covers June through August.", "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 Boston to Seattle?", "answer": "For Boston to Seattle, the best fares are typically found when booking 2 to 5 weeks before departure, with an average price around $268 and the absolute lowest fares about 25 days out. During peak summer and holiday periods, prices tend to rise sharply, so booking a bit earlier — around 6 to 8 weeks ahead — can help avoid the steepest markups.", "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.
