At the heart of this is that the fares you are seeking also have to align with particular revenue buckets, redemption availability, BA metal, and the tools you are using aren't helping. To give an illustration, there are DIF + UuA options available on 17 October, but there aren't many CW seats going mid October, it's too near in now. From 27 November onwards this alignment seems possible on virtually every day except around Christmas and Easter.
