Understanding Spirit Airlines Checked Baggage Policy is essential for budget-savvy travelers. Spirit does not include checked bags in its base fare, so passengers must pay separately. Bag fees are tiered based on timing and location of purchase—cheapest when booked online. Checked luggage must weigh under 40 pounds and stay within the size limit of 62 linear inches. Overweight or oversized bags can result in hefty fees. Spirit recommends paying in advance to reduce costs. Being informed about baggage charges allows travelers to pack smarter and avoid unnecessary expenses. Visit Spirit’s official site for current baggage rates and restrictions.
