On the 841 days we compared, Discount Den was cheaper on 777 of them (92%), by $5 on average. Count the days it saved nothing and that's about $5 per one-way trip.
A quick test: divide Frontier's current yearly fee by $5. That's roughly how many one-way trips from Cleveland a year, booked close to departure like these, before the membership pays for itself.
