Make an in-flight elbow war a thing of the past with this $30 gadget.

On flights that are increasingly jammed full of bodies, the average passenger is so squeezed in that they have to share one (or both). But thanks to a clever new product, you might never have to elbow your neighbor in the ribs over an airline seat again.
