Prepare yourself to minimize the chance of a loss, take matters into your digital hands, and have your case in order when you need the airlines to pay up for their mishap. Fortunately there isn’t much to it aside from a few good clicks, clock hand ticks, and learning to deal with airline…personnel.
I found Anil’s suggestion of taking pictures of your bags, and the contents while packing and ingenious idea. Especially if/when the need arises to explain to the airline personal at baggage claim what your bag or backpack looks like or what they could expect to find inside. Because chances are your bag or backpack looks similar to the 10’s of thousands of other bags or backpacks that go through airports everyday.
