Low-budget airline Frontier is back with a mega flash sale, with one-way nonstop deals across the country starting as low as $20 or $39 round-trip. We're even seeing deals to San Juan for as low as $97!

Keep in mind that Frontier charges extra for everything from a carry-on bag to a seat assignment to a can of soda. Still, even if you choose to bring a full-size carry-on bag aboard your flight and lock in a specific seat, you will likely end up paying less than on full-service carriers. Also note that the dates you can fly vary by route, so make sure to click "About This Deal" before you book.

If you want to book, we suggest you don't wait as these fares expire at 11:59 PM on September 16!

To search, head to Frontier's website and enter your origin and destination cities. Scroll through the calendar function to find dates and prices that work for you. Finally, click through to book directly with the airline.
