UNDATED (CNN) -- A 9-year-old boy from Minneapolis managed to sneak on a plane to Las Vegas, apparently without a boarding pass.
A 9-year-old boy walked off a light rail car Thursday and into the Minneapolis airport with plans to travel, but no ticket!
He passed through the security checkpoints of TSA screening no problem.
Then, continued on to the G Concourse to gate G4. But it's still unclear exactly how he got passed the Delta ticket agent here at the gate, collecting tickets.
What is known is this minor did board flight 1651 and traveled some 1300 miles to Las Vegas.
Officials say it wasn't until the flight crew became suspicious because he was traveling alone and contacted Las Vegas metropolitan police who took the child into custody upon landing.
Air transportation expert Terry Trippler says the whole thing highlights big gaps in security especially when it comes to children. Trippler says, "That nine-year-old child does not need identification. Anyone under 18, so I can understand standing behind a family. Or the family is checking in. I can understand that. I cannot understand the Delta gate agent. And this is where I put the major problem. It happened there."
While no one would talk on camera, some did release statements. First, from TSA essentially saying they did their jobs, quote, "The child was screened along with all other passengers to ensure that he was not a threat to the aircraft."
And then, delta, quote, "Delta is taking this incident very seriously and working with authorities in the investigation. Due to the fact that it involves a minor we are not commenting further at this time."
For the traveling public, who know the rigorous routine of airport screening, it's a mystery how a child could have slipped through the cracks.
