Hello.
Hello. How can I assist you at this moment?
I am Shirley Thomas. I am planning to attend a feast at Washington, can you please help me to book a ticket from OAK to DCA?
Sure Shirley Thomas, I will help you with that.  Can I have your travel dates please?
Sure, my itinerary dates are 10/29 and 10/31.
Ok Thomas, please wait a moment to check flight availability.
Ok.
Sorry Shirley Thomas, no flight is available to you on your dates due to some weather conditions.
It's ok. Thank you for your information.
