Hello, I am Steven Roberts.
Hello. How can I aid you?
I would like to book a flight ticket from Boston on 01/18 to participate in robotic workshop and I intend to return on 01/20. Can you help me to book a flight ticket?
Sure, I can help you. Can I know your airport codes?
My airport codes are from  MA-BOS to DC-IAD.
Do you need any connection limit?
Yes, I need a break in between my journey.
Ok. We found a UA airline, flight number:1001 and the price is 100.
That's fine, you can go ahead.
Your flight ticket has been confirmed.
Thank you.
