And let's not forget that the airlines assume NO liability for loss or damage to fragile items or valuables. T&C's expressly forbid you to place these in your checked luggage.
It seems they have dumbed down the checked baggage process to the extent that they cannot trust their own staff, or outsourced staff, not to steal from their customers.
And they charge an arm and a leg (much higher than their own -45/100kg freight charges) for the privilege of checking a bag.
They have only got themselves to blame.
