As an AI language model, I don't have real-time information or access to specific airline policies. However, as of my last knowledge update in September 2021, I can provide you with some general information about name change policies that are commonly observed by airlines like Delta Airlines. Please note that these policies may have changed since then, so it's always best to check directly with Delta Airlines or refer to their official website for the most up-to-date information.
