With one stop, depending on the layover city, total travel time often ranges from 7 to 9 hours. The return flight from Seattle to Baltimore is usually about 30 minutes shorter due to prevailing winds." }, "q1": { "question": "Are there any direct flights from Baltimore to Seattle?", "answer": "Yes, Alaska Airlines and Southwest fly nonstop from Baltimore to Seattle, both operating daily. Alaska runs up to 27 weekly flights with departures ranging from early morning to evening, while Southwest offers around 14 weekly flights spread across the day. Typical fares on the route run about $268–$274.", "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.

Rideshare services like Uber and Lyft pick up on the third floor of the parking garage, while metered taxis are available on the same level at the north and south curbs. Rental car shuttles run 24/7 to an off-site facility, and King County Metro buses stop near the light rail station on International Boulevard. Shared-ride vans and hotel shuttles offer door-to-door service, but the light rail remains the top choice for its speed and reliability.", "toolsUsed": [], "references": [ { "url": "https://www.portseattle.org/blog/smooth-sailing-guide-between-sea-airport-and-seattle-cruise-terminals", "title": "Smooth Sailing Guide between SEA Airport and the Seattle Cruise Terminals | Port of Seattle", "time_published": "2025-05-05T00:00:00Z" }, { "url": "https://www.portseattle.org/blog/wander-while-you-wait-exploring-beyond-sea", "title": "Wander While You Wait — Exploring Beyond SEA | Port of Seattle", "time_published": "2025-08-18T00:00:00Z" }, { "url": "https://en.wikipedia.org/wiki/SeaTac_Airport", "title": "Seattle–Tacoma International Airport - Wikipedia", "time_published": "2003-07-10T00:00:00Z" }, { "url": "https://en.wikipedia.org/wiki/Seattle%E2%80%93Tacoma%20International%20Airport", "title": "Seattle–Tacoma International Airport", "time_published": "2026-04-29T19:20:41Z" }, { "url": "http://www.portseattle.org/exploremore?page=1&tid=125", "title": "Explore More List | Port of Seattle", "time_published": "2000-01-01T00:00:00Z" } ] }, "q4": { "question": "When is the cheapest time to fly from Baltimore to Seattle?", "answer": "The cheapest months to fly from Baltimore to Seattle are November, October, and September, with average fares around $301, $321, and $368 respectively.

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 Seattle?", "answer": "For the best fare from Baltimore to Seattle, book 4–6 weeks ahead, with the lowest prices around $272 at 30 days out. For summer and holiday travel, aim for 6–8 weeks in advance, as prices can rise quickly closer to departure.", "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 Seattle?", "answer": "No nonstop red-eye flights operate from Baltimore to Seattle, but connecting overnight itineraries are available.
