Passed through the North Terminal this week (BA from BLQ). After immigration, we waited by the screens to show us which baggage re-claim to go to downstairs ...and waited ...and waited ...for half an hour, after which I said I'd go downstairs and see what's up.
Got downstairs to see our bags going round-and-round and to hear an announcement (which was not being broadcast upstairs) telling us which reclaim to go to
It can't be that hard, can it?
