The first time I saw this sale from Frontier Airlines, I was shocked.
The second time, not as much.
They have the sale a few times per year, and it’s here again, today only:
For Tue., Wed. and Sat. flights between Aug. 15-Oct. 4, you can get 75% off your base fare by using the code SAVE75.
Black-out dates: Sept. 2 and Sept. 5.
There are some excluded routes, which you can check out here, but this sale is better than previous ones because it includes Saturday flights.
I tried out a few searches to make sure it works, and sure enough, the fares are very cheap (much better than the Spirit Airlines 99% off sale, which I found to be a scam).
Here is the fare calendar for the non-stop San Francisco to Orlando route, with the code applied:

One-way fares for SF-Orlando.
It’s a pretty good deal if it works out with your travel plans, but some of the deals will be slightly better if you’re a member of Frontier’s Discount Den ($50/year).
Here is some fine print:
