Spirit Airlines has a promo code valid for puchase today only. Save up to 50% off the base fare for travel this summer and fall. Fares start at just $53 roundtrip.

Just enter promo code 50PCT when booking on Spirit.com to apply a 50% discount to the base fare for travel on Mondays, Tuesdays, Wednesdays, Thursdays, and Saturdays, from June 5 through June 20; and Tuesdays and Wednesdays, from June 26 through October 31. Avoid blackout dates on June 11 and July 3.

Although we've seen better prices in past promo code sales, this promo code does discount summer travel, which usually is not included in promo code sales. Lowest available fares are generally not available during peak summer months, but flights will still be discounted.

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. There is also a large list of excluded markets in this sale.

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 29, 2018.
