A luggage screening failure Saturday at the San Jose International Airport caused delays of up to two hours for arriving and departing flights as travelers were asked to evacuate a terminal so that security officials could re-examine them and their carry-on items .

Shortly after 3 p.m., Transportation Security Administration employees notified airport officials that “luggage may have been improperly screened and prohibited items may have been introduced into our sterile area,” said airport spokeswoman Rosemary Barnes.
