The return leg averages 9 hours 40 minutes, making the eastbound direction shorter by about 25 minutes due to prevailing winds.", "methodology": "Carrier service, flight times and distances for this route come from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We report the days of the week and the departure times each carrier operates. 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. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.", "toolsUsed": [ "flight_schedule" ] }, "q3": { "question": "What are the ground transportation options in Seattle?", "answer": "From Seattle-Tacoma International Airport, the Link light rail is the most popular option, reaching downtown in about 40 minutes for a flat fare. Taxis and ride-shares (Uber, Lyft) offer door-to-door convenience in 30–45 minutes depending on traffic, picking up on the parking garage's third floor. Rental cars are available via a free 24-hour shuttle to an off-site facility. King County Metro buses also serve the airport, and pre-arranged shuttles or charter buses can be booked for group travel.", "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 Paris to Seattle?", "answer": "The cheapest times to fly from Paris to Seattle are September (around $453 average), January (about $462), and October (about $463), while the most expensive months are December (around $568), June (about $547), and July (about $539). Overall, the low season runs September through February, and the high season spans March, July, June, and December.", "methodology": "This seasonal price baseline is a 365-day daily curve of typical round-trip fares for the route, precomputed monthly in-house from Priceline's own air booking-summary archive (the same data that backs the site), not a third party. For each calendar day we take a representative round-trip fare — a blend of the 25th-percentile and average ticket price over the route's bookings — and Gaussian-smooth the series so it reads as a clean seasonal trend rather than day-to-day noise. Thin and international routes are neighbor-filled: the seasonal shape is borrowed from the nearest dense routes (by origin-and-destination great-circle distance) with the price level anchored to the route's own bookings, so a sparse route still shows a plausible curve. It reflects current fares and is refreshed monthly.
