Don't know what the problem has been to cause the delay. The 762 arrived back at LBA from IBZ this morning more or less on time at around 04:30. It was scheduled to leave LBA again at 07:05 this morning for PMI but has only left at 18:40 this evening, almost 12 hours late!
ETA at HUY is now showing as 23:45, which still seems a little bit optimistic, just over 5 hours to fly LBA-PMI-HUY including an hour or so turnaround at PMI!
