An airfoil includes an airfoil wall having an exterior airfoil surface and an interior surface. The interior surface provides an airfoil cavity. A baffle is arranged in the airfoil cavity and provides a baffle wall having first and second portions spaced from one another on first and second sides. A tube interconnects the first and second portions and is configured to convey fluid through the tube between the first and second sides. The airfoil is cooled by supplying cooling fluid to a baffle arranged within an airfoil. The cooling fluid is passed through baffle cooling holes to a gap between the baffle and airfoil to cool an interior surface of the airfoil. A portion of cooling fluid is conveyed from one gap location to another gap through a tube in the baffle. Another portion of the cooling fluid is passed through film cooling holes in the airfoil.
