Whilst this is an older post I nonetheless thought I'd provide an update on the "Row 4" shadowing from a WP1 experience. As background,I generally select 4C or 4D outside T-80 (available to WP1) and predominately fly the BNE-SYD-MEL routes. What I have been finding for most of this year, at least, is that whilst most of the flights are reasonably lightly loaded, there are many vacant B and E seats behind Row 4, however more often than not, Row 4 is fully occupied. I suspect what is happening is that QF believe that there is already one benefit provided (leg room) by sitting in Row 4 therefore they are less inclined to provide the additional benefit of shadowing, and that any shadowing policy commences in Row 5 and beyond. Whilst using Expertflyer (using an NB profile), I can confirm with an earlier post that the seat block/shadowing beside me (WP1 Row 4C/D) is consistently removed with T-1. So WP's, take some comfort knowing that the lack of shadowing in Row 4 appears to be equally applied to WP1's.
