Thursday is expected to see 161,000 people departing, arriving and connecting while Friday is expected to see 171,000. SEA projects 143,000 Saturday, 129,000 Sunday and 160,000 Monday.

SEA recommends travelers arrive at least two hours before their boarding time for a domestic flight and three hours before an international flight.

The Port of Seattle said more than one-third of the airport’s daily passenger volume arrives at the airport before 9 a.m. with two more peak periods of 2-5 p.m. and 9-11 p.m.

The airport recommends using Spot Saver, an appointment system for security screening that uses dedicated lanes through TSA checkpoints.
