Do you have a flexible travel schedule? If so, I assume you're thinking about your open-ended travel schedule. If so, relax and book a flight with Delta Airlines. The airline completely understands the concerns of its customers, which is why it offers a simple Delta Airlines cancellation policy that enables everyone to cancel their reservation without any extra labour or costs. The policy is fairly easy to understand. Say there are no refunds available for Delta Airlines trips. There will be no refund if you decide to cancel your ticket.
