Most credit card rewards programs don't allow you to transfer your points directly to another person, but you can oftentimes convert them to airline miles or hotel points and give the person those. Be mindful that you might have to pay transfer fees.

You can give miles to a family member, but the "how" depends on whether you want to move the miles themselves or just use them to buy a flight. Most programs allow you to book a reward flight for someone else using your miles at no extra cost; you simply enter the family member's name as the passenger during the checkout process. However, if you want to transfer the actual miles from your account to theirs, nearly all airlines (like Delta, United, and American) will charge a significant fee—often around 1 cent per mile plus a processing fee. This often makes transferring miles a poor financial value. A better alternative is "Family Pooling," offered by airlines like JetBlue, Spirit, and many international carriers (e.g., British Airways, Emirates), which allows family members to combine their points into one shared pot for free, making it easier to reach the threshold for a free ticket.
