Processing can take 60 minutes or longer during peak periods, such as holidays and summer travel season, when multiple international flights arrive daily, typically between 10 a.m. to 3 p.m. Pacific DST. When scheduling connections from an international flight at SEA we recommend that you schedule enough time for processing to prevent missed connections for your next boarding times.

Upon exiting CBP's agriculture and baggage inspection, connecting passengers will go left (following the orange walls) and check their luggage for the next flight. All connecting passengers must go through U.S.'s Transportation Security Administration (TSA) security screening* at the South Satellite.
