Hello,.
Hello, how can I aid you today?
Can you please help me in changing my existing reservation, as my exam got postponed.
Sure, I am here to help you.
Thank you.
May I know on whose name the ticket has been reserved formerly?
I made the reservation on the name of Brandon Lee.
Sorry Brandon Lee, there are no flights reserved on your given name formerly.
Ok, no issues. Thank you for your help.
Welcome, thank you for choosing us. Have a great day.
