Call it the benefits of hub life: There are more than a hundred destinations you can reach from Seattle's airports, served by more than 30 airlines. Travel as close as San Juan Island (35 minutes of scenic cruising) or as far-off as Dubai (more than 14 hours in an airliner) and never suffer the indignity of a layover. 

We catalogued all the direct flights from Seattle-Tacoma International Airport, plus our other, smaller runways. Note that some flights are seasonal, and as is always the case with an international hub, the flight maps (like Sea-Tac's domestic and international ones) are ever-evolving. Before your flight, make sure you snag a spot to skip the security line. 

From Sea-Tac: Pacific Northwest | California and Southwest | Mountain West | Midwest and Texas | South | Mid-Atlantic and New England | Alaska and Hawai'i

International: Canada | Mexico and Central America | Europe | Asia and South Pacific

Other Airports: Paine Field | Boeing Field | Float Planes
