While discounted tickets are the primary perk of the Frontier Airlines Discount Den, there are other advantages that make this program worthwhile. For one, members are among the first to know about special promotions and flash sales. Additionally, being a Discount Den member may improve the availability of low fare options, especially during peak travel times when deals are limited. Although Frontier Airlines is an ultra-low-cost carrier, combining Discount Den with other cost-saving strategies, like booking in advance and avoiding add-ons, can make a big difference in your travel budget.
