Promotional Earn
Promotional earn is an accrual rate above a programme's standard earn, offered for a limited period or through a specific partner to stimulate a particular behaviour. It applies to points or miles only, not to tier status, and is typically excluded from award availability calculations that assume base accrual.
Promotional earn is not a loyalty benefit. It is a demand management tool that uses extra points to move bookings or spending into a window the programme wants to fill. The operator prices the promotion against the base accrual rate and against the award chart, usually without touching either.
Programmes run these campaigns because the short term economics are simple. A 50 percent bonus on a route with empty seats costs less than cutting the cash fare by the same amount. The risk is behavioural: members learn to wait for the next promotion, and base accrual starts to look like a penalty.
Consider a hotel programme that normally gives 10 points per dollar on a stay costing 200 dollars. A promotion doubles that to 20 points per dollar for stays in March. A member taking four such stays earns 16,000 points under the promotion instead of 8,000 points at base, an extra 8,000 points. Those extra points do not change the award chart, which still prices a free night at 25,000 points.
The trap is valuing promotional earn at face value. The extra 8,000 points are only worth the redemption they can buy, and award availability is the binding constraint. A programme can run a double points offer every month and still deny a free night on the dates members actually want.
Treat base accrual as the real rate. Promotional earn is a temporary discount that expires, it rarely counts toward tier status, and it disappears if the award chart is devalued before redemption. Members who compare programmes on promotional earn alone are comparing the loudest marketing, not the best loyalty programme.
