How to Save Money with Spirit Airlines, which is known for its ultra-low base fares, but extra fees can add up quickly if you're not careful. With the right strategies, you can fly affordably without surprises. To maximize savings with Spirit Airlines, start by booking early and flying midweek when fares are lowest. Avoid unnecessary fees by traveling with just a free personal item (18x14x8 inches) or pre-paying for bags online, which is cheaper than at the airport. Always check in via the Spirit app to skip boarding pass printing fees, and consider joining the Free Spirit loyalty program for exclusive deals. If you fly frequently, the $9 Fare Club can unlock steep discounts on flights and bags. Pack smart, skip seat selection unless necessary, and use the Spirit Airlines World Mastercard® for perks like free checked bags. By planning ahead and minimizing extras, you can enjoy Spirit’s ultra-low base fares without surprise costs.
