A Las Vegas bound plane was diverted to Portland International Airport Thursday afternoon when at least one passenger said a couple was trying to join the "mile high club," FOX 12 Oregon is reporting.

"The people across the aisle from us were fooling around in their seats and they decided to go to the bathroom and fool around and they threatened the flight attendant,” said passenger Jessica Smith, according to FOX 12 Oregon.

The couple was escorted off the plane, according FOX 12 Oregon.
