Airport and airline officials are reviewing video and gathering information as they try to figure out how a 9-year-old boy evaded security and stowed away on a flight from Minneapolis to Las Vegas without a ticket.
Delta Air Lines issued a statement Monday saying it's reviewing its policies and procedures to make sure it doesn't happen again.
Officials say the boy took a light rail train to Minneapolis-St. Paul International Airport on Thursday. They're still not saying how he got past security screeners and gate agents to board the flight, which was not full. The flight crew later became suspicious and handed him over to authorities in Las Vegas.
The Transportation Security Administration says he was screened along with other passengers to ensure that he was not a threat.
