The latest incidents:
The guitar belongs to a British-born musician, Jon English, the keyboard to a member of his band.
This is how they came off a Virgin Airlines flight from Coffs Harbour to Sydney this weekend.
Mr English, who publicised the incident on his facebook page, accused Virgin Airlines baggage handlers of ‘running over our musical instruments with their baggage trailers’. He said it was the second incident in three months.
Virgin say they’re very sorry.
