There are probably easier animals to smuggle onto a plane.

A woman was kicked off a US Airways flight in Connecticut earlier this week after trying to sneak a pot-bellied pig on board for support.

Jonathan Skolnik told ABC News he saw the woman board the plane with what he thought was a duffel bag.

"But it turns out it wasn't a duffel bag. We could smell it and it was a pig on a leash," he said. "She tethered it to the arm rest next to me and started to deal with her stuff, but the pig was walking back and forth."

Skolnik estimated the pig weighed 50-70 lbs.

A spokesman for American Airlines, parent company of US Airways, told ABC the pig was brought on board for emotional support. The woman, and the pig, were asked to leave when the pig became disruptive, the airline said.
