Changing the name on a Frontier Airlines ticket is generally not allowed. However, you may be able to correct a minor error, such as a typo, by contacting Frontier's customer service within 24 hours of booking. For significant changes, like a full name change, you will typically need to cancel your existing ticket and book a new one under the correct name. It's important to review Frontier's policies or contact their support for specific guidance, as fees may apply for cancellations and rebookings.
