A flight attendant pleaded guilty Monday to making false bomb threats against several United Airlines flights, causing flight delays and intensive searches of passengers, authorities said.

Cau admitted to making the false bomb threats from October 2012 to January 2013. He used pay phones in several U.S. cities, including Los Angeles, New York City, Las Vegas and Seattle, according to the statement.
"As a direct result of Cau's threats, United experienced substantial disruption to its business operations and services, including cancellations of and delays to flights, transfer of aircraft, and significant inconveniences to United passengers," the statement said.
Cau was also expected to be ordered to pay an undetermined amount of restitution to law enforcement agencies that responded to the bomb threats.
