Spirit Airlines launched a new sale yesterday which is giving 90% off base fares when using promo code 90PCT. You have until February 5, 2026 to redeem the promo code, but be aware that there are lots of limitations regarding eligible travel dates.

The Deal
- Save 90% off Spirit Airlines base fares when using promo code 90PCT.
- Direct link to offer.
Key Terms
- Percent discount will apply only to the base fare, including the flight portion of a vacation package, regardless of travel option selected, purchased at spirit.com or via Spirit’s app.
- To receive 90% off the base fare, enter 90PCT (no spaces) in the promotion code box when booking a flight.
- Travel must be booked by 11:59 PM EST on February 5, 2026.
- This offer is valid only on new flight and vacation package bookings made at spirit.com for travel: 2/10/26 – 3/11/26 (Tue/Wed/Sat Only). Blackout Date: 2/21/26.
- Once the promotional code is entered, fares displayed will automatically reflect a promotional discount of 90% off base fares.
- Please note that the value of the coupon does not apply to the Passenger Usage Charge (up to $27.99 per segment).
- The coupon will apply to the remaining balance once this is deducted from the combination of the ‘Base Fare’ and ‘Fuel’ (where applicable).
- The coupon code does not apply to our highest class fares (Y, B, H), which are our highest fares and may be the only fares available on certain dates or flights.
Quick Thoughts
90% off base fares sounds amazing, but it sadly doesn’t mean you’ll save 90% of the cost of a flight. That’s because the base fare doesn’t include things like taxes and fees, including Spirit’s up to $27.99 per segment charge. The promo code will save you money if you travel on eligible dates; just be prepared for the eventual discount to be less than you might originally anticipate.
Speaking of eligible dates, the promo code is only valid for travel from February 10 through March 11, and then only on Tuesday, Wednesday, and Saturday, with February 21 also being blacked out.
The promo code expires on Thursday February 5, so you have today and tomorrow to make use of it.
Past Offer Dates
- January 12-14, 2026





Can Spirit agents at the airport apply this code to bookings? Would that be a potential way to avoid the $27.99 fee?
I think that level of generosity (and capability) would be asking too much of Spirit.
