OK, I understand. But if I was moved from 20A to 20C, that would imply the disabled person could have been placed in 20C (in fact I would think that a disabled person would be better served by an aisle seat). And if the disabled person needed to sit next to a companion, why couldn't the companion go in 20D? (which is indicated to be empty).
