Type promo code DEEZNUTS into the promo code box on the home search screen and the discounts will be included in the results. Even DenDeals fares are discounted. (See Should You Join the Frontier Discount Den for more information on DenDeals.)


Screen Shot 2015-08-22 at 5.53.24 PM The 50% discount will not drop the total price by 50% because it only applies to the base fare. More expensive fares will see a larger percentage discount on the total price. But cheaper fares can still get a little bit cheaper.

Here’s a $29 DenDeals fare from Denver to Las Vegas that drops to $21.55.

If you want to fly in the next three weeks, there are some really cheap fares on the entire Frontier route network!


Frontier now follows the ultra-low-cost, fee-for-everything model.

Seat selection costs $4+. They’ll assign you a seat at check in for free, but you’ll probably get the worst one.

Only a personal item is free to bring on board. Checked bags cost $20+ and carry ons cost $30+, so I would think of these fares as costing $20 more each way and plan on checking a bag.

Even water costs money. Here’s the snack and drink menu.

Getting These Flights for Free

There’s no need to actually pay cash for cheap, cash fares. The Citi Prestige® Card comes with a $250 Air Travel Credit every calendar year that will cover the purchase of this ticket. If you haven’t used the credit yet, buy this fare with your Prestige, and you will receive an offsetting credit on your next statement, so you’ll get a completely free ticket. The Air Travel Credit will also offset seat selection, baggage, and food fees.
