The reason for my inability to travel is [provide a brief description of the reason, such as a medical emergency, family emergency, or travel restrictions imposed by authorities]. I have attached relevant supporting documents, such as medical certificates or official travel advisories, to substantiate my claim. As per the airline's refund policy, I would like to request a full refund of the airfare amount. I believe that under these extenuating circumstances, it is fair to receive a refund. I have been a loyal customer of your airline and have always appreciated the excellent service provided. Therefore, I kindly request your understanding and the prompt processing of my refund. Please advise me on the necessary documents or procedures I may need to complete in order to facilitate the refund process. I am more than willing to provide any additional information that may be required to expedite the refund.

This would enable me to reschedule my travel plans with your airline in the future, allowing me to continue our valued relationship. I appreciate your attention to this matter and your prompt response. I remain hopeful that your airline's customer service will assist me with arranging a satisfactory solution regarding my refund request. Thank you for your understanding and cooperation.
