Hi.
Hello. How may I help you?
I am Patrick Gonzalez. Can you please book a flight ticket from ORD to DCA?
Sure, tell me your travel dates please?
My travelling dates are 05/15 and 05/17.
Do you have any preferences?
I need a ticket under normal cost.
Thanks for your patience. I have found Delta airlines which flies with one connection.
 You can proceed with booking.
I have confirmed your flight ticket in flight number 1005. Thank you.
