When planning a trip with a budget airline like Spirit, understanding the cost of extras is just as important as booking your flight. Spirit Airlines is known for its ultra-low fares, but many travelers are surprised by the additional fees that come with luggage. Being prepared and knowing what to expect when it comes to baggage charges can help you save money and avoid last-minute stress at the airport. One of the most important things to note is that Spirit does not include any free checked bags with their base fares. In fact, even carry-on bags come with an added fee unless you're traveling with just a small personal item that fits under the seat. Because of this pricing model, many passengers opt to travel light, but for those who need to check a suitcase, understanding the pricing structure is key. Spirit Airlines Checked Bag Fees vary depending on several factors, such as when you pay for your bags, the route you're flying, and the size and weight of your luggage. The earlier you pay for your checked bag, the better. Booking online at the time of your ticket purchase typically offers the lowest rates. If you wait until you get to the airport, you’ll likely pay a significantly higher price. Additionally, Spirit charges extra for overweight or oversized bags, so it’s crucial to weigh your luggage before arriving at the airport. Staying within the airline’s baggage limits can help you avoid additional charges that could quickly add up.
