When it comes to flying on a budget, Spirit Airlines is one of the most popular ultra-low-cost carriers in the United States. While the base fares are incredibly affordable, passengers often find themselves navigating a variety of fees for services that are typically included with other airlines. One of the most important aspects to understand before booking your ticket is the Spirit Airlines Checked Baggage Policy. Being informed ahead of time can save you both money and hassle at the airport.
Spirit Airlines operates under an à la carte pricing model, which means you only pay for the services and extras you choose. This model applies directly to baggage—checked bags, carry-ons, and even seat selections all come with additional fees. Spirit’s aim is to offer a customizable flying experience where travelers only pay for what they actually use.
Unlike traditional airlines, Spirit does not include any checked baggage in the base fare. Passengers who wish to bring checked luggage must purchase it separately, either at the time of booking or later through the airline’s website or app. Fees vary depending on when and how you purchase your baggage allowance.
