For those of you who are missing your luggage and the airline has no idea.

If you had any meaningful identifiers in your luggage, including the luggage tags attached to the bag, consider contacting FedEx and UPS to check with them. Sometimes luggage and bags get sent to their warehouses on accident the same way someones luggage ends up on the wrong flight: bad luck, the bag people not paying attention, etc. Before the disaster fill out those identifier cards with your name and number LEGIBLY not in your flashy signature and wonky writing, and add additional identifiers inside any side pockets. This creates more chances that, in the event it is sent to a warehouse, they have thoroughly documented the information on file as it goes to the Lost and Found and Eventually Thrown Away warehouse. The reason you might not get a phone call is because some warehouse workers in that position just wont bother, and otherwise many pieces of lost luggage end up having no idea tifiers other than a luggage airline tag that has no information beyond a name. Every piece of your luggage needs a "if found please contact me at" or something.
