Spirit Airlines name change policy allows passengers to correct minor errors in their booking details. For significant changes or name transfers, a fee applies, and such requests must be made through their Guest Service team. Minor corrections, like fixing typos or adding middle names, can usually be done online or by contacting customer service. More substantial changes, such as a complete name change due to legal reasons, require documentation, such as a marriage certificate or court order. It's important to review and request changes promptly to avoid travel disruptions. Always check Spirit Airlines’ website for the most current policy details.
