To identify refundable Delta tickets, look for fare types labeled as “Flexible” or “Refundable” during the booking process. These tickets are typically in First Class or Business Class and can be fully refunded if canceled according to Delta’s terms. On the other hand, many Economy tickets are non-refundable. Understanding fare classes and associated policies is crucial when purchasing your ticket. To explore your options, visit Delta’s official website or speak with a representative for assistance.
