Usually the *A RTW fares book into one of the more expensive (non-flexible) economy fare buckets which typically earn 100% (or at least not 0%).
Yes, that's a good question. Q is one of the lowest booking classes on SQ. W (which is refundable but not fully flexible) is usually only a small amount more.
