Frontier is running multiple promotions currently. Actually, the $29 flights to Florida and Puerto Rico aren’t even close to the best prices right now, though they may be the best deals. Those flights must be booked by 11:59 ET tonight.

However, Frontier has a wide array of $19, $20, and $25 fares at the moment, for flights across the country. Check out their Fare Deals page for routes.

Sample Sale Fares Between City Pairs

  • Austin & New Orleans for $19
  • Las Vegas & Phoenix from $20
  • Cincinnati & Raleigh/Durham from $20
  • Atlanta & Long Island from $25
  • Austin & Detroit from $25

Frontier is also currently touting it’s fuel efficiency, as it’s been rated as the “most fuel-efficient domestic airline in the U.S.” for 2017 and 2018. According to the International Council on Clean Transportation, they are 7% more efficient than their nearest competitors and over 10% more efficient than the industry average. That’s a nice touch for environmentally conscious travelers. Though maybe squirrels are still feuding with the airline.

Remember, the Florida deals expire tonight, no matter how green you are. The other deals vary, so check the Deals page for exact terms.
