In this photo taken Tuesday, Aug. 11, 2015, at Seattle-Tacoma International Airport, TSA agents are surrounded by travelers in lines that snake past, in Seattle. When it comes to counting passengers, Sea-Tac is the fastest growing of the top 20 airports in the United States, which is putting a strain on services and creating long lines at the security check points. A record 4 million passengers passed through the airport in June. When the numbers are counted for July, they'll likely top June's record and August is always a busy month of the year.
