But there's an exception to this rule: If you're packing something really valuable, you may want to consider purchasing excess valuation (EV) from your airline. It's not insurance per se, but it increases the airline's liability limit.

You can sometimes buy baggage insurance from car-rental companies and travel agencies as well.

The idea is, she said, “that you readjust by eating in line with local time ― not just sleeping on local time.” This revelation could be an easy fix for jet lagged travelers everywhere.
