Modern security screening equipment and highly skilled employees work at Washington Dulles International Airport to guarantee a fast and comprehensive security procedure. For domestic flights, it is recommended that passengers arrive at least two hours before the scheduled departure time, and for international flights, three hours in advance to provide sufficient time for security screening, check-in, and any required customs processes. For those who qualify, United Airlines IAD Terminal has TSA PreCheck lanes, which speed up the security check process.
