1. A vane arc segment comprising:
an airfoil fairing having first and second platforms and an airfoil section extending there between, the first and second platforms having, respectively, first and second openings that open into the airfoil section,
the first and second platforms each defining first and second circumferential mate faces, forward and aft sides, a gaspath side, a non-gaspath side,
the first platform having:
a first flange projecting radially from the non-gaspath side of the first platform aft of the first opening, the first flange extending in a first flange length-wise direction between the first and second circumferential mate faces of the first platform, and
a second flange projecting radially from the non-gaspath side of the first platform forward of the first flange, the first and second flanges being the only flanges on the first platform, and
the second platform having:
a third flange projecting radially from the non-gaspath side of the second platform aft of the second opening, the third flange extending in a third flange length-wise direction between the first and second circumferential mate faces of the second platform, and
wherein the second flange extends in a second flange length-wise direction from the first circumferential mate face to the forward side of the first platform.
