Travel insurance companies will always want documentation of the value of the items for any lost baggage to determine the amount of reimbursement to which you’re entitled. For baggage loss, to receive reimbursement for higher-value items (generally above $150 value), you may have to provide the original receipt. Some insurance providers will provide the actual cash value if you can’t provide a receipt. For baggage delay, you’ll need to show that anything you have purchased is a reasonable expense and fits within the coverage limits defined by your policy. Keeping receipts of anything you are buying while your bags are delayed is strongly recommended.
