1. An airfoil for a gas turbine engine, comprising:
a body defining a pressure side and a suction side, the body extending between a leading edge and a trailing edge and also extending along a radial direction to define an outer edge;
a radially-extending plenum disposed at the outer edge of the airfoil and having a suction-side sidewall and a pressure-side sidewall;
a flared portion disposed at the outer edge of the body and extending from the suction side, the flared portion; and
a recess disposed in the outer edge and positioned between the flared portion and the suction-side sidewall of the radially-extending plenum.
