To perform a name change online on Wizz Air, start by logging in to your Wizz Air account on the official website. Navigate to the "Manage Booking" section, where you can view and modify your reservation details. Look for an option specifically related to changing passenger information or correcting a name. Select the passenger whose name needs to be changed and follow the prompts to enter the updated information. Keep in mind that not all fare types may allow online name changes, so it's essential to check the terms and conditions associated with your ticket. Additionally, be prepared for possible fees, as Wizz Air typically charges for name changes, and the costs may vary. If faced with any challenges during the online process, or if the option isn't available, contacting Wizz Air's customer service for further assistance is recommended. Always review the details carefully before confirming any Wizz Air name change online to ensure accuracy.
