MINNEAPOLIS -- The Transportation Security Administration is considering changes after a 9-year-old boy was able to get through security,board a plane at the Minneapolis-St. Paul International Airport without a ticket and fly to Las Vegas.

The incident happened Thursday morning. Metropolitan Airports Commission spokesman Patrick Hogan says security screened the Minneapolis boy at the airport shortly after 10:30 a.m. He then boarded a Delta flight that left for Las Vegas at 11:15 a.m.

Hogan says the flight crew became suspicious and contacted Las Vegas police, who met the crew upon landing and transferred the boy to child protection services.

Hogan says the boy is expected to return to the Twin Cities.

On Sunday, the TSA released a statement saying "The child was screened along with all other passengers to ensure that he was not a threat to the aircraft."

The TSA added they have "reviewed videotape of the child at the checkpoint and are investigating whether they should reconfigure the barriers to prevent another incident like this one."

For its part, Delta released a statement saying the airline is committed to cooperating with authorities.

"Delta continues to work with authorities and look into the circumstances involving an un-ticketed minor boarding an aircraft in Minneapolis-St. Paul,"said Deltaspokesperson Leslie Scott in a written statement. "We commend the flight crew of flight 1651, whose vigilance and awareness of the cabin led them to proactively alert authorities to the situation prior to the aircraft landing in Las Vegas. Safety and security are always Delta's highest priorities and we are reviewing our policies and procedures to make sure something like this does not happen again."

The day before the boy boarded the aircraft he was spotted eating at the restaurant Hot Dish, which is outside the secured area. MSP officials say he took someone's luggage off a carousel before heading to the restaurant.During his visit, he asked a server to watch the luggage while he went to the restroom but he never returned.
