Tried - unsuccessfully - to use this today to get a seat back on a fully sold flight from Stuttgart tomorrow. I am now 'waitlisted' for the flight, but my understanding is that RA would get me 'confirmed' on it. Our company travel person told me that the company TA (BTI, to name the guilty party) did not seem to know of the existence of this feature, and very likely did not ask BA for it. I even provided a link to Ask BA. Grrr.
