Frontier is back with another big promo code sale spring travel. Take 75% off nonstop domestic flights for mid-week travel this spring. Fares start at just $51 roundtrip.

Use promo code SAVE75 when booking on to take 75% off the base fare for nonstop domestic flights on Tuesdays and Wednesdays, from March 26 through June 12, 2019. Avoid blackout dates on April 16, 17, 23, 24, and May 28.

The discount does not apply to taxes nor Frontier's online booking fee, which is labeled a "Carrier Interface Charge". This means some routes still won't have a very big price drop even with the big sticker shock of 75% off. However, there are plenty of routes where we are seeing some big price drops, especially for some dates in March that are currently priced pretty high.

If you are unfamiliar with Frontier Airlines, please read our guide on Everything You Need to Know Before You Fly Frontier.

There are specific routes excluded from this promo code sale and you also may have to click around to find available dates since Frontier operates about half of its route network on just a few days each week.

Tickets must be booked by 11:59 pm ET, tonight, March 11, 2019.

A sample of nonstop fares include:

Atlanta to Miami $51 roundtrip

Charlotte to Orlando $72 roundtrip

Minneapolis to Denver $72 roundtrip

Washington D.C. to Orlando $75 roundtrip

These fares all work in reverse and there are many more routes available as well. Lowest fares may not be available throughout the entire travel period. You'll have to decline all extras to get the lowest price.

Keep in mind that Frontier charges extra for any bags larger than a small personal item (small backpack, large purse, etc.). Pack super light to get the lowest price. Checked bag fees start at $25-30 each way. Larger carry-on bag fees start at $30-35 each way.
