Fly from Denver to Fairbanks, Alaska for $289 round-trip, nonstop, including all taxes, using the current promo offer from Frontier.

We found seats departing from DEN on May 21, and returning from FAI on May 31. This is a hidden fare, meaning that once all flights are selected the fare will drop, revealing the lower fare of $289 on the final booking page. This fare also requires the 20% off promo code PLAYBALL, as mentioned in the Fare Details.
