Hello.
Hello, how may I help you?
I am Thomas Lee. Please help me to book a flight ticket in my preferable travel dates Sept, 26 and Sept, 28.
Do you need any halt in between your journey?
No, I need a direct flight.
Sure, may I know your respective airports codes please?
My airport codes are DEN and IAH.
Sorry, there is no direct flight for you on your route.
That's ok, no problem.
Thanks for choosing us, have a nice day.
