The latest promo code sale on Spirit Airlines allows you to take up to 75% off the base fare for travel this summer and fall. Fares start at just $49 roundtrip.

Just enter promo code 75PCT when booking on to apply a 75% discount to the base fare for roundtrip travel on Tuesdays, Wednesdays, and Saturdays, from August 21 through December 12. Avoid blackout dates on September 1, October 6, and November 15-27.

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 certain routes. There is also a list of excluded markets for this sale. This list is not entirely accurate so it doesn't hurt to try any route and see if it will discount travel within the dates listed above. I noticed some routes listed are discounting and some not listed are not discounting at time of posting.

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

Promo code expires at 11:59 pm ET, tonight, August 7, 2018.
