Hello.
 Hello, how can I support you today?
I have to do some modification in my previous flight ticket booking that there is a sudden event held at my home town, so I am unable to travel the trip. Can you please help me out in changing my reservation?
Sure, may I know your name to check further?
Sure, myself Gregory Garcia.
Sorry, no active reservation found with your name in our records to change it.
It's ok, thank you for your help.
Thank you for contacting us.
