Hi.
Hello. How may I assist you?
I have to change my reservation dates in my ticket, can you please help me in changing my existing reservation?
Ok, may I know your name to check your reservation?
I have reserved my flight ticket with name Patricia Hill.
Please wait for a moment, while I search for your reservation.
Ok, take your own time.
Thanks for your time, there is no reservation found under your name to change it.
Ok, fine thank you for checking.
