Officials said a monkey that was on a plane at McCarran International Airport Tuesday night was a passenger's service animal.
McCarran officials said the animal was on Frontier Airlines Flight 1087 from Columbus, Ohio. The flight arrived around 11 p.m.
Las Vegas police said the monkey was never loose on the plane.
In addition, the passenger had the proper paperwork to have the monkey on the plane as an emotional support service animal.
While the monkey was a certified service animal, the man who brought it aboard did not tell Frontier ahead of time and refused to turn over documents verifying the monkey's status, a Frontier Airlines spokesman told the 13 Action News.
"They were made aware when a flight attendant noticed the monkey inside the male passenger's shirt," according to Frontier.
The monkey was brought onto the plane in a duffel bag.
The man was met by Las Vegas police when the plane landed and once the passenger showed his required papers, he and his monkey were free to go.
13 Action News also reached out to the TSA to ask how the monkey made it past the agents. They told us once the animal is cleared, it’s up to the airlines to determine whether there’s any "monkey business" going on.
Tuesday's monkey is not necessarily the most exotic animal to fly on a plane as a service or companion animal.
A Seattle woman who was flying to San Francisco to spread her husband's ashes took her 25-pound pet turkey on the flight for emotional support.
And let's not forget Hamlet, the 70-pound pot belly pig. Megan Peabody once battled anorexia, and she says Hamlet is important to her recovery.
