Hello.
Hello, how can I assist you?
I would like to change my existing reservation due to my leaves got cancelled by my manager, so please help me in changing my existing reservation to Dallas.
Sure, may I know you name please for checking your reservation status in our database?
My previous reservation has done with the name of Brandon Brown.
Sorry Brown, I have not found any reservation by your name in our database.
Ok, not an issue. May be something went wrong while booking the ticket.
Ok, what else can I do for you?
Nothing, enough with this information. Thank you for providing information.
