Frontier is back with another flash sale, though no emails have been sent yet. The sale is available at Frontier’s website as well. Frontier recently ran a limited $15 sale, and $19/$20 fares are generally as cheap as they get. The base fares for these are actually less than $1; the main charges are taxes and fees.

This sale is good through Monday the 9th, with these parameters.

  • Book by 11:59 PM September 9th (tonight)
  • Valid for travel 9/14-11/19
  • 7 day advance purchase

The Deals page has plenty of options, as well as sales with different timelines, as usual. I see no “promotional code” required for sale prices, so just hop over and buy.
