SEA playbook
→Data status
This page is currently backed by 6 live SEA checkpoint readings, so the terminal and checkpoint spread matters more than a single airport-wide average.→Airport context
SEA's official security page lists six checkpoints and identifies lane types by checkpoint.→Airport context
The live wait-time page recommends two hours before domestic flights and three hours before international flights.→Airport context
SEA calls out additional peak periods from 2-5 PM and 9-11 PM, so the airport can be busy outside the normal morning rush.Terminals at a glance
→Terminal note
Checkpoint 1 is closest to A and S gates and lists general screening, TSA PreCheck, and CLEAR options.→Terminal note
Checkpoint 2 is closest to A and S gates and supports general screening plus SEA Spot Saver during its published hours.→Terminal note
Checkpoint 3 is a central option with general screening, TSA PreCheck, Touchless ID, and premium-lane options.→Terminal note
Checkpoint 4 is open 24 hours and is closest to the Central Terminal plus B and C gates.→Terminal note
Checkpoints 5 and 6 are closest to C, D, and N gates; Checkpoint 5 is PreCheck-focused while Checkpoint 6 includes general, premium, PreCheck, and CLEAR options.Airline notes
→Airline routing
Alaska Airlines passengers should aim for Checkpoints 5 or 6. Delta and international carriers typically route through A gates or the South Satellite.→Airline routing
South Satellite (Gates S1-S16) handles almost all foreign international arrivals and selected Delta international departures.Local tips
→Local tip
SEA publishes checkpoint-by-checkpoint lane types and hours, so choose by service need: general, premium, CLEAR, SEA Spot Saver, or TSA PreCheck.→Local tip
SEA states that all gates are accessible from any checkpoint, which makes shortest-line selection more useful than at terminal-isolated airports.→Local tip
Checkpoint 4 is the 24-hour checkpoint, while the other checkpoints have published daily windows that can change by operation.
