Hi. I am Donald Garcia.
Hello, how may I aid you?
I would like to book a flight ticket to attend a robotic workshop, can you help me to book a  connecting flight?
Sure, help me with the trip dates?
I would like to travel on dates 06/22 and 06/24.
May I know your airport codes that you wish to board and land?
My airport codes are ORD and EWR.
Do you have any preferences?
I want to return at evening.
Thank you for your details, we do not found any flights running in your desired routes.
That's ok, thank you for the response.
Thank you for reaching us. Have a nice day.
