Hello.
Hello.
My name is Christine Walker.
Walker, how may I aid you today?
I want to do some changes in my existing reservation. Can you help me for that?
Sure, I am here to help you. Hold on for a moment. Let me check.
Thank you. I will wait for your response.
Sorry Walker, there are no flights reserved on your given name.
That's ok, thank you for checking.
