As Memorial Day marks the unofficial start of summer travel, Seattle-Tacoma International Airport (SEA) is preparing for one of its busiest weekends in recent years. Nearly 1 million travelers are expected to pass through the airport between Thursday and Monday, setting the stage for packed terminals, long security lines, and the need for traveler patience and planning.

Why the Surge?

  • Pent-up Demand: After several years of pandemic-related disruptions, domestic travel demand is surging again.
  • High Airline Capacity: Carriers have increased routes and flight frequencies, particularly to sunbelt states and national parks.
  • Holiday Timing: With schools wrapping up and the long weekend offering a break from work, Memorial Day is one of the year’s most popular travel windows.

What SEA Travelers Should Expect

1. Peak Hours:
Expect the heaviest congestion from early morning (5–9 a.m.) and mid-afternoon (2–6 p.m.) on Friday and Monday.

2. TSA Delays & Real ID Reminders:
Travelers are urged to arrive at least 2 hours before domestic flights and 3 hours before international ones. The TSA is also reminding passengers that the federal REAL ID deadline is approaching in 2025—standard driver’s licenses will soon no longer be accepted for domestic flights unless compliant.

3. Parking & Ground Transit Challenges:
Parking garages are expected to fill early. SEA is encouraging use of public transit, including light rail and shuttle services.

4. Family Travel Spike:
With schools out, the airport is seeing more families and first-time flyers. Kid-friendly amenities and staff support teams will be active throughout the terminals.
