Is there an official policy for cancelled flights with confirmed GPUs, or is it up to individual agents? I had a situation when a 1K agent claimed PZ bucket has to be available, and refused to rebook me into business as only revenue space was available, even for the next day. I hanged up and called again, and another agent rebooked me into revenue J on LH for the same day. I suspect the agents have a lot of discretion, and wonder what are the limits.
