It frequently takes place. A Delta flight may need to be cancelled after being booked. Changes in plans or another factor could be the blame for the cancellation. It's a good idea to be aware of the possibility of a Delta flight cancellation in case this occurs to you. After all, just as with every flight, there is probably a Delta cancel flight policy you must follow if you want to receive a refund. If you employ DoNotPay's assistance, your chances of cancelling your flight on time and getting a refund will be increased. Many people are curious as to whether they have 24 hours to cancel their Delta ticket. Anyone who purchases a ticket directly on Delta.com or through the Fly Delta app is entitled to a "Risk-Free Cancellation" as part of Delta's "Customer Commitment." This means that if you purchase a qualifying eTicket, you have up to 24 hours from the time you book your ticket to cancel and get a full refund without paying any costs.
