Jetstar says it will investigate who defaced a passenger's luggage in transit, using stickers to spell out "I am gay" on his suitcase.
The man posted a photograph of the red suitcase on Twitter yesterday, saying the wording was done using ticket stubs from checked luggage on his flight from Perth.
"Utterly disgusted to find my luggage front and centre on the luggage carousel looking like this," said the married father-of-two, who gave only his first name, Aaron.
The post caused anger among his followers, who described the incident as disgusting and unbelievable.
It is unclear when the stickers were put on the case, and who was involved. After it is checked in by airline staff, bags are usually handled by luggage contractors as it is loaded on to the plane.
