Airline promo codes can sometimes save hundreds of dollars on flights by simply entering a few characters into that "promo code" box you see on the airline's website. Here, we've rounded up the best airline promo code deals that are available right now.

Promo code sales have been updated as of February 20, 2020.

Frontier Airlines' Discount Den members can take 75% off winter/spring flights and non-members are able to take 25% off flights through mid-June. Volaris has a sale for up to 40% off flights through May and flights between Edmonton and Toronto are discounted 15% on Flair Airlines.

Airline Promo Code Sales

We see weekly promo code deals on Spirit, Frontier, and Volaris. These types of deals are less common on other airlines. Lately, Alaska Airlines has been offering more promo code discounts, and every once in a blue moon, we'll see a promo code sale on JetBlue or Norwegian Airlines. Other carriers tend to stick to targeted promo code deals for specific users, but we'll be sniffing these out every day to bring you the latest promo code offers on all airlines.

While you may sometimes see unbelievably high percentage off promo code sales on ultra-low-cost carriers like Frontier and Spirit, keep in mind that the discount only applies to the "base fare" and does not apply to taxes nor booking fees. Both Spirit and Frontier have high booking fees, so the actual discount may not be as much as you'd expect.
