It depends. Some points programmes allow point sharing, others don't. Airpoints Dollars, for example, cannot be transferred, but you can earn points jointly with friends and family in a Shairpoints group, or use your Airpoints to buy a flight ticket as a gift for someone else. Read your card's terms and condition to check for details about points transfer. If transferring is not allowed, you can treat a loved one with a gift card bought with points instead.
