Hello.
Hello, how can I serve 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, I will help you. May I know your good name please?
Thank you, myself Pamela Mitchell.
Please wait for a while.
Ok.
Thanks for waiting, there is no active reservation found on your name.
That's fine, thank you.
Thank you for choosing us, have a nice day.
