A "frequent flyer program" is a service used by the airlines to reward customer loyalty. So what you do is: you enrol for free and then you start accruing "frequent flyer" miles based on how far you're travelling, how many tickets you buy and what grade of class (business class, first class), what kind of travel you're doing. As you accrue the points on the frequent flyer program then you just rack them up and then start redeeming them.
