Southwest Airlines only allows minor corrections such as typos or spelling errors on tickets, not complete name changes. If you made a mistake, reach out to their customer service to request the correction. If a full name change is required, you’ll need to cancel and rebook. Act quickly to avoid losing your fare options.
