Instead of paying $300 for noise cancelling headset, they paid $99 by switching UPC code. Store doesn't have to show that the item cost $300, only that they charge $300 for it.
But in that case, the person is taking *a completely different item* that the store has and can easily show damages there as they can no longer sell that item. Someone on an HCT is still using part of the ticket they purchased. Your analogy would work if someone forged a boarding pass to get on a different flight, but falls flat when talking about HCT.
