The claims must be getting expensive.
I see the newest weapon in the Equity Aviation arsenal is a liitle form that you must complete when you check in luggage, stating that there are no valuables, cameras, laptops, etc in your checked luggage.
I can see no possible operational or safety reason for this. It can only be to limit claims: "But Sir, here you stated that there was nothing of value in your luggage. So if your bag was broken into, the only thing that could have been stolen is your privacy, and we don't re-imburse for that."
