Hello.
Hello, how can I be a help for you?
I want to change my reservation, becasue I have another important work on those dates so I am unable to catch the flight. Can you please change my reservation?
Sure, may I know your good name please?
Sure, my name is Robert Campbell.
Sorry, there is no reservation found on your name to change.
Oh! It's ok no problem. Thank you for your information.
Thank you for approaching us.
