What is the purpose of a frequent traveler program?

The purpose of a frequent traveler program is to provide benefits based on travel frequency. These programs are designed for individuals who travel regularly with a particular airline, hotel, or other travel service. By encouraging loyalty, these programs reward members with various incentives such as points, miles, upgrades, discounts, and exclusive access to services. This model not only fosters customer loyalty but also enhances the overall travel experience for frequent travelers, making it more rewarding.

In contrast, the other options do not align with the primary goal of frequent traveler programs. For example, unsold tickets or categorization of ticket types pertains more to pricing strategy and inventory management rather than loyalty incentives. While offering insurance might be an added benefit through some travel services, it is not a fundamental purpose of frequent traveler programs.
