An airfoil assembly includes first and second ceramic airfoil pieces that each have first and second platforms and a hollow airfoil section that connects the first and second platforms. First and second spars extend through, respectively, the hollow airfoil sections. A seal has a seal body that defines at least one orifice and a seal portion. The first spar extends through one of the at least one orifices and the seal portion bridges a mate face between the first platforms of the first and second ceramic airfoil pieces.
