The latest promo code offer from Spirit allows you to take 85% off the base fare by entering promo code 85PCT when booking on Spirit.com.

The discount will only apply to the base fare and not to Spirit's booking fees (which were raised again this week) nor taxes so don't expect to see that large of a price drop on certain routes. Even so, there are many routes that will be discounted heavily.

Tickets must be booked by 11:59 p.m. ET, tonight, February 6, 2018.

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.

Need to bring more than just a personal item? Checked baggage starts at $30 each way on Spirit so most fliers will likely have to pay at least $60 more round-trip for baggage. This can still end up being a significant savings compared to the competition on certain routes. We ask that you just read up on Spirit 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 we as we have found fairly often lately, this list seems to be pretty inaccurate. For instance, Managua and St. Thomas are listed as excluded, while we're still seeing the promo code discount these routes at time of posting. There are also certain markets not listed that are not allowing for a discount at this time. This could be corrected at any time. Spirit appears to be having some trouble with their website at time of posting. We're experiencing slow loading pages and some errors.
