If you need to change your name on a Ryanair flight ticket, act quickly to avoid high fees. Minor spelling errors can be corrected for free within 24 hours of booking. However, full name changes or major corrections require a fee of €115 to €160, depending on how and when the request is made. You may need to provide documents such as a passport, marriage certificate, or legal name change document for verification. Changes can be made online through your Ryanair Name change account or by contacting customer support. Always double-check your details before booking to avoid unnecessary charges.
