Hello.
Hello. How may I help you?
Due to change in my plans to visit Dallas, I would like to change my existing reservation. Can you help me with this?
May I know your name please to check your reservation status?
My name is Charles Thompson.
Charles, no reservation has been found on your name.
Ok, not an issue. May be something went wrong while booking the ticket. Thank you for providing information.
Thank you for choosing us.
