Hi.
Hello, how best can I guide 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,  please share your good name?
Myself Stephen Scott.
Please wait for a moment.
Sure.
Thank you for waiting, there is no recent reservation found with the given name.
It's ok, thank you for your help.
Thank you.
