Frontier is having a promo code sale for very specific flights in select markets for travel either between noon, December 24 and noon December 25, or between noon, December 31 and noon, January 1. Entering promo code HOLIDAY on FlyFrontier.com will apply a 99% discount to the base fare for the specific flights listed on the sale page, between those dates/times only.
By using this promo code, I was able to find seats departing Milwaukee MKE on Monday, December 31, returning from Las Vegas LAS on Friday, January 4, for $127 roundtrip. The discount only applies to the base fare on the outbound flight New Year's Eve. It arrives in Las Vegas at 3:42 pm, so you'll still have time to enjoy the New Year's celebration in Las Vegas, and ample time to recover by returning a few days later.
If you would like to stay for a longer trip in Las Vegas, lower fares are available returning from January 8th, onward.
Since Frontier also has a 75% off promo code sale (promo code: SAVE75) for daily travel through Dec. 18, and Monday through Thursday and Saturday travel, from January 8 through February 6, you can get a roundtrip total of just $75 for a trip departing December 31, returning January 9, for example. This would require booking two separate one-way flights using the two different promo codes.
Keep in mind that Frontier's fares only include a small personal item. A checked bag costs $30 each way when purchased during booking. Larger carry-on bag fees start at $35 each way.
If you want to avoid all extra fees, read How to Pack in Just a Personal Item Sized Bag.
Both promo code sales expire at 11:59 pm ET, tonight, December 3, 2018.
