Determining the value of the Frontier Airlines Discount Den depends on your travel habits. For most regular travelers, the math checks out: a $59.99 annual fee (subject to change) can yield hundreds in savings over the course of a few trips. However, it’s important to note that the program doesn’t include traditional perks like mileage accumulation or airport lounge access. Instead, it focuses on upfront savings and simplicity. If you're comfortable with the airline’s à la carte pricing model and often travel to cities served by Frontier, the Discount Dene is not just worth it—it’s a smart investment.
