Hello.
Hello, how can I aid you today?
I want to change my existing reservation. Could you help me with that?
Sure, I am here to help you. May I know on whose name the ticket has been reserved formerly?
Barbara Walker.
Ok, hold on for a moment. Let me check.
Ok.
Sorry Barbara Walker, there are no flights reserved on your given name formerly.
That's ok, no problem. Thank you.
Welcome, thank you for choosing us. Have a great day.
