How does seat-miles matter here at all? That's not a normal metric used in this field.

Using seat-miles leads to some very strange conclusions. Consider cargo aircraft with zero seats, or a helicopter that mostly hovers in place all day.

Aviation safety primarily looks at airframe hours and pressurization cycles. At least on the mechanical side.
