We’ve seen similar offers in the past from Frontier. But this discount only applies to the base fare price so you don’t really end up with a half priced fare at the end. There’s also lots of excluded markets.
Also make sure you familiarize yourself with their fees, to keep this a good deal. As is the case with most budget airlines, they will charge you for almost anything extra.
