So I called, and the friendly and helpful agent (who from their accent I'm guessing was based in AKL) was able to release 1x J award seat on Aug 9th QF136 CHC-SYD. Flight was showing I1 so I'm happy with that.
However for the outbound SYD-CHC on the previous Thursday, which also was (and still is) showing I1, he said the bot wouldn't accept the request. On my app I can see a SYD-CHC booking with a booking reference, but in the booking status field it has "-".
Does that mean that somehow the agent was able to submit a request? Or is that just an empty booking shell leftover from his attempt which doesn't really mean anything?
Also, for short-haul flights how unusual or otherwise is it for the bot not to accept requests to release seats even if I inventory is showing?
