The Port of Seattle, including Seattle-Tacoma International Airport, is facing internet and system outages, potentially due to a cyberattack, officials announced on Saturday.

The outages are affecting web-based services, leading to possible disruptions like long lines and delays at baggage check and ticketing counters.

The Port has isolated critical systems and is working to restore full service but has not provided a timeline, KING 5 has reported.

Travelers are advised to check in with their airlines for updates, load mobile boarding passes, and register checked bags through airline apps before arriving at the airport.
