Sadly you appear to be correct. PZ space shown on seats.aero right now is very limited, multiple days old, and is missing a number of flights I've found through manual searching. Unfortunately it looks like, for the moment at least, I'm back to searching the old-fashioned way for PZ space. This is going to make TATL searching much harder when I've got multiple gateway cities I can use AND flexible dates.
