Nonstop flights typically take 5 hours and 50 minutes, while the return leg is shorter at 5 hours and 5 minutes due to prevailing winds. Connecting itineraries generally range from about 7 to 10 hours total.", "methodology": "Flight times and distances come 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.", "toolsUsed": [ "flight_schedule" ] }, "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. Together they offer about 41 weekly nonstops, with departures spread from early morning through evening.

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. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours. 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": [ "route_airlines", "flight_schedule" ] }, "q3": { "question": "What are the ground transportation options in Seattle?", "answer": "Seattle-Tacoma International Airport (SEA) offers several ground transportation options to the city center. The Link light rail is the most popular and efficient, reaching downtown's Westlake Station in about 40 minutes. Taxis and rideshares like Uber and Lyft are available on the third floor of the parking garage, providing a direct 30- to 45-minute drive depending on traffic. Rental cars are located off-site with free shuttle buses, and King County Metro buses also serve the airport. For the fastest door-to-door service, a taxi or rideshare is best, but the light rail is the most used due to its reliability and cost-effectiveness.", "toolsUsed": [ "article_lookup" ], "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" } ], "methodology": "Airport details are drawn from the sources listed with this answer, primarily the airport operator's official website along with airline, lounge-operator and transit-authority pages, collected by our research process and refreshed periodically.
