I’m not sure whether I’ve got any unclaimed Qantas flight credits.
I haven’t looked, either because I’m too busy or can’t be bothered. Which is exactly what Qantas wants. And not only Qantas. Separating out those people who are desperate or determined to get their money from those who give up is a standard business practice.
It’s called price discrimination, although Qantas appears to have added a twist.
