Hi, myself William Phillips.
Hello, welcome to flight booking agency. How can I assist you today?
My business meeting has been postponed, so I would like to change my existing reservation.
Ok, let me check for the previous reservation in our data base.
Sure. Take your own time.
Your patience is greatly appreciated. William, there is no reservation found under your name.
That's alright, no problem. Thank you for your help.
You are welcome. Thank you for contacting us.
