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, may I know your name to check further?
Myself Paul Perez.
Sorry, no reservation found on your name in our portal to change it.
It's ok, thank you for your help.
Thank you for contacting us.
