Hello.
Hello, how may I serve you at this moment?
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, we are here to help you.
Thank you.
May I know your name to check your reservation status?
My name is Anthony Brown.
Ok, please be on hold.
Sure.
Thank you for waiting, sorry to inform you that we could not find any  reservation on your name.
It's ok, thank you.
Thank you for choosing us.
