Sea-Tac tips and airport app, from Port of Seattle

As the commute to the airport and security lines are constantly under some sort of change, our fliers have shown interest in learning about it and about how to stay more up to date. Here we share some valuable tips from Port of Seattle:

Plan ahead: busiest travel days are Thursdays and Fridays and congestion tends to happen during holidays. Arrive early!

Check for roadway construction updates: see all of the traffic and roadway construction alerts that could impact you getting to Sea-Tac Airport.

Peak traffic congestion: on the Departure level, the busiest hours are usually from 4:30am to 7:30am, and 11:00am to 2:00pm. For both, Arrivals and Departures, heavy traffic often occurs from 8:30pm to 12:30am, and during holidays.

Take public transportation to the airport: it is the best option to avoid being stuck in traffic, either the Link Rail, a bus, or a shuttle. The Link Light Rail takes you to the airport and the Tukwila and Angle Lake stations offer free parking to avoid airport traffic.

Go opposite: in the morning, drop off on the Arrivals level, and in the evenings, meet passengers on the Departures level.

Come from the South End entry: to avoid the heaviest traffic.

Arrive early: plan on arriving 2 hours in advance for domestic flights, and 3 hours for international.

Be ready for security checkpoints: travelers are required to remove electronics larger than a cell phone from their carry-on luggage, so be prepared to do so if you’re carrying any.

Properly store food for screening: passengers are allowed to bring food but sometimes that can slow down the screening process. Sea-Tac recommends you pack food in the checked luggage if you’re not eating this in the airport or in your flight.

Sign up for Trusted Traveler Programs: such as TSA Pre✓, Global Entry, and CLEAR. These expedited security programs help for both domestic and international travel, including a faster way through customs with Automated Passport Control and Mobile Passport Control.

Relief areas for passengers traveling with pets: there are three new indoor pet relief areas in the terminals for easier access and compliance with Americans with Disabilities Act (ADA). Check the website for an up-to-date map and info.

Blind and low vision travelers: can try new assistive technology with Aira, with the Port providing free connection service while at the airport.

More amenities for traveling mothers: look for Sea-Tac’s seven nursing suites throughout the airport.

What’s all that construction?: Sea-Tac began its Central Terminal Renovation Project, and other major projects are also underway such as the North Satellite ModernizationInternational Arrivals Facility, and one you don’t see, the Baggage System Upgrade.
