Hello, how may I aid you?
My name is Brian Walker.
Nice to meet you.
 I am planning to travel from SFO to IAH to attend my sister's wedding, could you please help me with booking a flight ticket?
Ok. May I know your travelling dates?

Please hold on. There is no flight available with your details. Sorry for inconvenience. Thank you for choosing us, have a nice day.
