McCarran International Airport spokeswoman Melissa Nunnery told the Las Vegas Review-Journal that a flight staffer said "the monkey was loose, or got loose" in the main cabin of the flight. There was no clarification as to what "loose" meant.

"The monkey was never loose in the cabin," Frontier spokesman Richard Oliver told the Las Vegas Review-Journal Wednesday. "It was always with the passenger it was traveling with."

Oliver told The Associated Press that the passenger violated policy by not telling the airline about bringing a service animal on board, saying that the passenger secretly brought the animal on the plane in a duffel bag. He was seen styowing the monkey in his shirt.

According to Oliver, the passenger would not hand over documents verifying the monkey was a certified service animal.

Whether or not the passenger will face consequences is not clear, but McCarran International Airport spokeswoman Christine Crews said law enforcement officials met up with the plane and determined the monkey was a certified service animal.
