Hello.
Hello.
I am Paul Walker.
How can I assist you at this moment?
 Actually I am an old person and I don't know how to modify a flight ticket that is booked by my son in the last week but suddenly I got admitted in hospital with a typhoid fever, so I am unable to travel the trip and my son is busy in his office work. Can you please help me in changing my flight ticket?
Sure Paul Walker, I will help you with that.
Thank you for your positive response.
Please wait a moment to check flight availability.
Sure.
Sorry Paul Walker, no reservation has found under your name to change.
Ok, that's fine. Thank you for your help in searching and providing the information.
Thank you for choosing us, have a good day.
