From check-in and security to lounges, boarding, and arrivals, this comprehensive guide offers everything you need to know about flying with British Airways through Seattle.
British Airways operates its international flights out of Concourse S, also known as the South Satellite Terminal, at Seattle-Tacoma International Airport. This concourse is specifically designed to handle international arrivals and departures and is equipped with customs and immigration facilities, making it ideal for long-haul carriers.
The airport itself is one of the busiest on the West Coast, serving millions of travelers annually. Despite its size, SEA is well-organized, and the British Airways Terminal offers a streamlined, premium experience for both departing and arriving passengers.

Once through security, passengers heading to Concourse S board the Satellite Transit System (STS) — an underground train that connects the main terminal with the South Satellite Terminal.
The train ride is short, usually under five minutes, and runs frequently throughout the day. Travelers should still allocate enough buffer time in case of queues or mobility constraints.
