Do you belong to airline miles programs, hotel rewards programs, rental car loyalty programs, or any other program where you receive points for using certain companies?
Do you check those statements or online after returning home from a trip? You should. Now is the time to check with the airline or hotel if your points aren't there within a few days of use. Make sure you have your receipts. You can scan and email them if need be.
No sense belonging and not getting credit for your points.
