Spirit Airlines is an "Ultra-Low-Cost Carrier" (ULCC), which means their base fare includes very few "frills." In 2026, the only things that are "free" with a standard Spirit ticket are your seat (randomly assigned at check-in) and one personal item (like a small backpack or purse) that must fit entirely under the seat in front of you (18×14×8 inches). Unlike "legacy" carriers, Spirit does not provide free water, soda, or snacks; even a cup of tap water will usually carry a small charge. There is also no free "carry-on" bag (overhead bin space) or checked luggage unless you have purchased a "Bundle" or have high-tier "Free Spirit" loyalty status. Essentially, you are paying for the "utility" of being transported from point A to point B. To save money, travelers are advised to bring their own empty water bottle to fill after security and download all entertainment to their personal devices, as there are no seatback screens or free Wi-Fi on board.
