Frontier has a sale with flights starting as low as $25 one-way. That fare includes all transportation fees, surcharges and taxes, but any extras will cost you with Frontier, as it’s the case with budget airlines. There’s plenty of routes available at $25.
Most fares need to be booked by the end of day today, May 30th, and you must fly by 6/21/2017. 7 day advance purchase required.
We’ve seen prices as low as $15 from Frontier in the past, but this is still a good promotion if any of these routes work for you. Just make sure you familiarize yourself with their fees, to keep this a good deal.
