Operational picture

What this status means for your airport plan

Work backward from the airline cutoff

SEA currently advises arriving two hours before domestic flights and three hours before international flights, with extra transportation time when airport roads are busy.

Check security options for your travel date

SEA Spot Saver is unavailable from November 30, 2026. Before that date, the Port says reservations through November 29 will be honored at Checkpoint 4. For later departures, plan around an eligible operating checkpoint and current wait estimates, not a Spot Saver appointment.

Gate and belt assignments can change

Treat the fields above as the latest reported operational data, not a guarantee. Follow airport displays and airline messages after entering the terminal.

Data source and freshness

Status source: AeroDataBox airport flight board. Last checked 4:36 AM PDT. Live coverage varies by airport and flight; missing fields are shown as unreported instead of estimated by seatac.co.

SEA times use Pacific Time. When the provider does not supply a remote airport time zone, that airport’s time is labeled UTC instead of being guessed.

Reported aircraft: Airbus A321 · Callsign FFT3406. Aircraft assignments can change before departure.
