Hello.
I am Jerry Martin.
Jerry, how can I aid you today?
I am planning to change an existing reservation, due to health issue. Can you please change my reservation?
Sure, I am here to help you. Hold on for a moment. Let me check.
Thank you. Sure.
Sorry Jerry, there are no flights reserved on your given name formerly.
That's fine. Thank you for your  service.
