Points Sharing
Points sharing is the transfer of loyalty points or miles from one account to another, whether between members of the same programme or across partner programmes, usually at a conversion rate set by the operator.
Points sharing is rarely the member benefit it is sold as. A programme that earns points from a co-brand card and from daily accrual gives a member two balances to manage. Sharing lets the operator charge a fee to move value between them. That fee is the real product.
The haircut is explicit in the conversion rate. A member who transfers 10,000 points to a partner account at an 80 percent conversion rate receives 8,000 points. The 2,000 point difference is the operator's price for moving money the member already earned. That is not a rounding error.
Cross-programme sharing adds another layer. Points moved into an airline or hotel programme are locked to that programme's redemption rates and expiry rules. If those points expire before redemption, they become breakage for the receiving operator, not the original issuer. The member loses twice: once on the conversion haircut, once on the expiry policy.
The industry presents pooling as a family convenience. In practice, a programme that charges a fee to share points between members of the same household is monetising the same balance twice: once at earn, and again at transfer. The operator has no cost to move a number in a database. The fee is pure margin.
The correct answer is usually not to share. Accrue points in the programme where they will be redeemed. If an account lacks points, top it up with a co-brand card spend rather than transferring from a richer account. Paying a haircut to fix a balance that could have been earned in the right place is a failure of accrual planning, not a feature.
