SEATAC — Four million passengers passed through Seattle-Tacoma International Airport in June, breaking a monthly record set in 2014 but straining services and creating long lines at security checkpoints.
Passenger traffic is up 13 percent so far this year, airport spokesman Perry Cooper said. The crowds could grow. Preliminary numbers show July will likely top June, and August is always a busy month of the year.
The Official Airline Guide, which collects data for the global airline industry, lists Sea-Tac as one of the fastest-growing among the top 20 airports in the U.S.
In response, the Transportation Security Administration added officers to screen departing travelers in Seattle. U.S. Customs and Border Protection has 10 new people to welcome arriving international passengers.
