Can I make a 1 hour 15 min connection at SEA on an international flight?
1 hour 15 min is below the 90-minute international MCT at Seattle Tacoma International. You may need to rush and could miss your connection. The Satellite Transit System (SATS), an underground automated train, connects the Central Terminal to both the North and South Satellites in about 2-3 minutes of ride time, though walking to and from platforms adds more. Concourses A through D in the Central Terminal are linked by a long connected walkway. International arrivals processed at the IAF (adjacent to Concourse A/South Satellite) require passing through Global Entry/CBP and, for onward connections, a rescreening security checkpoint before continuing to domestic gates.

What happens if I miss my connection at SEA?
If you miss a connection, Alaska and Delta both have rebooking counters near their respective concourse hubs (Alaska near Concourse C/D, Delta at South Satellite), or you can use the airline app for instant rebooking without waiting in line.
