You have to get in touch with Southwest Airlines directly +π-πππ-πππ-ππππ or or OR οΌοΌοΌοΌοΌοΌοΌοΌοΌοΌοΌοΌοΌοΌοΌ (OTA) if you want to modify the name on a Southwest Economy ticket. For non-refundable tickets, name changes are often not permitted; however, you can ask for a correction for small spelling mistakes. You might be able to get a change if your ticket is refundable.
