As usual, Spirit is starting the week with two new discount codes. You can save either 7.5% or 10% on the price of a round-trip flight at spirit.com, but you have to book before 11:59pm ET tonight.
To save 10%, use the promo code 10PCT. You can fly February 26 through March 20. Details here.
To save 7.5%, use the promo code 7.5OFF. You can fly April 2 through May 22. Details here.
These codes are good for round-trip bookings only. The discount comes out of your base fare; taxes and fees are added separately. Remember to book your flights before midnight!
