If baggage must be offloaded for 'no shows' how does baggage left behind get transported. I only ask because my wife and I managed to get to Australia without our bags ( 7 days for for mine and 10 for hers!!). Then on the way back 3 and 4 days to get it home after us.
It had not been opened (seals in place) so how did they know it was OK?
Should add - this was good old BA weeks before T5 opened.
