The delta change name on ticket policy is designed to accommodate passengers who need to make minor corrections to their booking information. This includes fixing typos, adjusting spacing, or updating a name due to legal changes like marriage or divorce. Delta allows these corrections as long as the ticket remains with the originally ticketed passenger—ticket transfers to a different individual are not permitted. For more significant changes, travelers may be asked to provide legal documentation and work directly with Delta’s customer service. Making the correction as early as possible helps avoid complications at check-in and ensures the name on the ticket matches your ID.
