Hello.
Hello. How may I aid you?
Due to change in my plans to visit Dallas, I would like to change my existing reservation. Can you help me with this?
Sure, may I know your name?
My previous reservation has done with the name Amanda Lewis.
Please give me a moment to check your reservation status.
Sure, take your own time.
Sorry Lewis, no reservation is found by your name.
Ok, not an issue. May be something went wrong while booking the ticket. Thank you for providing information.
Thank you for reaching us.
