Hello.
Hello, how may I aid you at this moment?
I am Sharon Walker. Can you help me to book a flight ticket from SFO to PHL?
Sure, I am really gleeful to help you in booking the flight ticket.  Please share me your journey dates of your planned trip.
Ok, my travel dates are 11/01 and 11/03 respectively.
Do you have a specification regarding flight ticket booking?
Please go ahead if there is a direct flight then book it.
Sorry Walker, here I didn't find any flight in your way.
That's fine, thank you for assisting me.
Thank you for approaching us.
