A feather seal assembly (72A) includes a seal (74A) having a directional passage (80) to direct an airflow generally non-perpendicular to the seal (74A). In one embodiment the directional passage (80) is formed in an axial seal (74A) and includes a tab (82) which permits the passage of a radial seal (76A) thereover in a single direction. The radial seal (74B) is then trapped between the tab (82) and a raised feature (84) on the axial seal (74A).
