Hello.
Hello, how may I assist you?
Due to some health issues I could not catch my flight at right time, so I need some help to change my existing reservation. Will you help me in changing?
Sure, may I know your good name please?
Sure, my name is Elizabeth Davis.
Ok, please wait for a moment.
Sure.
Thanks for waiting, no reservation found with your name to change.
No problem, thanks for your support.
Thanks for approaching us.
