The overweight baggage fees on Spirit Airlines vary based on the weight of the baggage and the route being traveled. The general overweight baggage fee for Spirit Airlines is $59 for bags weighing 41 to 50 pounds and $99 for bags weighing 51 to 100 pounds. If your bags are oversized (63 to 80 inches), you will be charged $100; for special items over 80 inches, the fee is $150.

However, airline policies and fees can change over time, so I recommend checking the Spirit Airlines website or contacting them directly for the most up-to-date information on their overweight baggage fees. For more details, you can see our website Spirit $9 Fare Club.
