A blade outer air seal (64; 164) includes a carrier (70; 170) that has a dovetail (76; 176) and a ceramic seal segment (68; 168) supported on the dovetail (70; 170). The ceramic seal segment (68; 168) has first and second axial ends (68a, 68b), first and second circumferential sides (68c, 68d), an inner side (68e), an outer side (68f), and first and second inward-facing dovetail hooks (72; 172) that project from the outer side (68f) and define a dovetail key (74). The ceramic seal segment (68; 168) is axially receivable onto the dovetail (70; 170) of the carrier via the dovetail key (74).
