You'll have that when your voltage overcomes the resistance of the air

Sometimes it happens even below the arc breakdown voltage via air... Air molecules are slightly less dense along the surface of a smooth flat surface due to molecular 'bounce', so electrons creep along the lower density of a surface.

Hence, creepage on a PCB.
