Some air carriers provide immediate cash relief for lost or delayed baggage. Save receipts for any expenses you incur as a result of the loss, damage or delay of your baggage since you will need these to substantiate your claim. Any interim payments may be considered an advance against any subsequent claim for loss or delay. The air carrier will take these into account when calculating a final settlement.
In some cases, you may be able to claim the difference between what the air carrier pays and the actual loss under your household insurance policy. If you purchased your trip with a credit card, the credit card company may also cover your loss.
