Hello. I am Gary Lee.
Hello, what can I aid you at this moment Lee?
Can you help me in booking a ticket from LGA to DCA?
Sure, I am here to help you. Can you please let me know your dates of journey?
My  planning dates are from 03/26 to 03/28.
There is a direct flight which costs 200. Shall I proceed?
I need a fight with 1 connection.
Sorry Lee, there is no flight with 1 connection limit to your destination.
That's fine. Anyway, thank you for your help.
Most welcome.
