The latest promo code offer from Spirit allows you to take 75% off the base fare of a round-trip purchase for travel between April and June. Fares start at just $51 round-trip.

Just enter promo code 75PCT when booking on to apply the discount for travel on Tuesdays and Wednesdays from April 4 through June 13. Avoid blackout dates on May 23 & 29.

The 75% 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. However, we're still seeing some decent discounts depending on the route.

Tickets must be booked by 11:59 pm ET, tonight, March 6, 2018.

Denver to Las Vegas $51 round-trip, nonstop

Columbus to Orlando $57 round-trip, nonstop

There are many more routes available as well. 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, purse, briefcase, etc.) that will fit underneath your seat. Checked baggage starts at $30 each way. If you don't know much about Spirit, we ask that you please read up on them and know all about their fees before flying so you don't get surprised at the airport.

Spirit lists a number of excluded markets in this sale, but this list isn't accurate. We're seeing pretty much any route that we search is actually being discounted at this time so even if your route is listed as excluded, give it a try.
