Spirit Airlines has a promo code valid for puchase today only. Save up to 85% off the base fare for travel this spring.

Just enter promo code 85PCT when booking on Spirit.com to apply a 85% discount to the base fare for travel on Tuesdays & Wednesdays, from May 9 through June 13, and again from September 5 through October 31.

The discount will only apply to the base fare and not to taxes nor Spirit's booking fees so don't expect to see that large of a price drop on most routes. The $103 round-trip fares will not see any discount, but higher fares on certain days may get a small discount.

If you are unfamiliar with Spirit, please read our guide on How to Fly Spirit Airlines.

Promo code expires at 11:59pm ET, tonight, May 2, 2018.

There are many more routes available as well. Domestic routes will work in reverse. Lowest fares may not be available for the entire travel period. You'll have to decline any extras to get their lowest price.

Spirit's Bare Fares only include one small personal item (small backpack, large purse, briefcase, etc.) that will fit underneath your seat. Checked baggage starts at $30 each way. Larger carry-on bag fees start at $35 each way.

Spirit lists a number of excluded markets in this sale, but this list isn't accurate. I am finding that some routes listed are actually being discounted and some roues not listed are giving an error when trying to apply the promo code. If your route is listed as excluded, give it a try, it just might work.
