Hi all, I have my first long haul sector in PE in early May. Config is 789 v1. Always managed to stay in Y or get a double RU to J....

Currently I can see 23AB and 23 DEF are all available for $75 and that 23 JK are occupied/blocked (can't tell from my seat select).
However, a dummy booking fo the same flight seems to indicate that 23 JK are just withheld/blocked and not occupied, presumably for 'load control' to allocate at some point.

Question - when do the blocked seats become selectable?

Combined screen shot of dummy booking and then actual booking.
