Hello.
Hello, how may I serve you today?
I have to modify my previous flight ticket booking due to an important work, so can you please help me with changing my ticket booking?
Sure, I am here to help you with this. May I know your name please?
Thank you and my name is Donna Nelson.
Ok, please wait for a mean while.
Sure, take your time.
Sorry to say, that there is no reservation found as per your name to change it.
Sad to hear that one, I can prefer any other source. Thank you for your help.
You are welcome.
