I would have to say that, although there's obvious questions re the video, Qantas has a baggage problem at Melbourne.
Being Tasmanian based, I pass through Melbourne a lot and I reckon it got to about every third flight my luggage went astray with Qantas. Launceston staff know my home address as they'd drop my errant belongings off on their way home! I pack my stuff in a Pelican case. Not the Pelican travel case, the original Pelican, life time guaranteed against pretty much anything. Travelling with Qantas, there's been two claims on that guarantee so far. Both honoured without question, I might add, but there's a lot of minor damage I haven't claimed for that would have wrecked a normal suitcase.
Last twelve months, I've been travelling Virgin. I might be jinxing it, but so far, no lost luggage and no damage. I'm flying nearly every week. Can't just be coincidence.
