Hi.
Hello.
I am Samantha Jackson.
How may I assist you?
Due to an emergency, I am unable to catch the flight on the dates which I have reserved, so can you please help me in changing my flight ticket booking?
Please hold on a moment I will check your reservation with your name, whether it is existed or not.
Ok, please check.
Thank you for your time, there is no reservation found with your name to change it.
No issues with that. Thank you for your information.
Welcome, have a good day.
