Boy, 9, gets past US airport security

Authorities in the US have ordered a review of airline security after a nine-year-old boy sneaked onto a flight to Las Vegas without a boarding pass.

The child successfully boarded a flight from Minneapolis to Las Vegas last week without a ticket or any documentation.

A spokeswoman for Delta Airlines declined to say how the boy had been allowed onto the flight.

Ironically his parents didn't know he was even at the airport, because the child had taken a tram from the city centre without his parents realising he had left the house.
