The infamous Spirit Airlines is offering 87.1 percent off flights booked by midnight tonight.

According to a spokesperson, the airline is celebrating their 87.1-percent on-time arrival rating and their efforts to improve operations and the customer experience.

By using the promo code JUST4U, travelers can save almost 90 percent off flights and vacation packages, resulting in some pretty outrageous airfare totals.

During the sale, fliers can find $12 round-trip tickets from New York City to Chicago, $18 round-trip tickets from Kansas City to Orlando, and an absurd $31 round-trip seat from Philadelphia to Los Angeles.

To take advantage of the sale, book your next trip (for travel between November 29 and February 13, excluding the holidays) by 11:59 p.m. on November 15.

The most recent report from the Department of Transportation, showing flight operations from August, indicated that 76.9 percent of Spirit flights arrived on time.

Spirit’s spokesperson suggested that this month, the airline is on target to surpass all domestic legacy carriers with their on-time performance score.
