For international flights out of Seattle Airport, the major airlines suggest getting to the airport 3 hours before your flight. For domestic flights, 2 hours should suffice. It's work knowing that as one of the busiest airports on the west coast it can have amongst the longest security lines, though the airport scores well for flight cancellations and delays.
