Frontier Airlines Sale

There’s a new Frontier fare sale where they are quoting prices at (up to) 90% off base fares. You need to use promo code SAVE90 when booking to get the discount. You need to Buy by 8/29/18. Fly 9/5 – 10/4/2018 in order to get the discount.

I did a few quick searches and found some round trip flights for less that $50 and that includes taxes and fees! Also, if you join their Discount Den you can save even more.

Offer Terms and Conditions

The key information for the offer is as follows:

  • Tickets must be purchased by 11:59 pm Eastern time on August 29, 2018
  • Valid Mondays through Thursdays and Saturdays 9/5 – 10/4/2018.
  • The 90% discount applies to base fare only, not to fees or taxes, and requires purchase at using promo code SAVE90.

There’s a long list of exclusions which you can see on promotion page.


A pretty good offer from Frontier but even though the sale is promoted as ‘90% off’, the discount only applies to the base fare. That means that it won’t really result in a 90% total discount. But, it should still yield some good prices, especially on the more expensive tickets. As usual, there’s also a long list of excluded markets for this offer.

Just keep in mind that any extras will cost you with Frontier, as it’s the case with most budget airlines.
