Now, earning frequent flyer points or reward point can be capped as well as uncapped. When it’s capped, you can earn points at a rate which is normal only up to a specified amount of points for a specified amount of time – for instance, 5000 points per year. After you’ve reached this particular point cap, you wouldn’t be able to accumulate more points, or the points that you accumulate will get substantially lower for what remains of the period.
