Sea-Tac Airport is located about 14 miles south of downtown Seattle off Interstate 5. Travelers can easily reach the airport from downtown Seattle by taxi or the Central Link light rail. Rail service runs from 5 a.m. to 1 a.m. Mondays through Saturdays and 6 a.m. through midnight on Sundays. Parking is available at the airport for travelers who choose to drive their own vehicles. General parking rates are $3 per hour or $28 per day, and it takes approximately 20 minutes to drive from downtown to the airport.

More than 20 airlines serve Sea-Tac with regularly scheduled domestic and international flights, including nonstop flights to London aboard American Airlines, British Airways, and Iberia Airlines.
