Frontier is back with another flash sale. And like 2 weeks ago, this one for their birthday. The airlines is sending emails for a $25 sale (look for “It’s our 25th Birthday 🎉🎈 2 million seats on sale from $25!” subject lines), with typical parameters for booking and travel. As usual there are also deals with nearly the same parameters for lower than the advertised $25 price.

  • Buy by 7/7, fly 7/12 – 11/20
  • Travel Tuesday and Wednesday
  • Blackout date September 3
