Hi, I am Stephanie Carter.
Hello. How may I help you?
I would like to book a flight ticket from IL - ORD to TX - DFW.
OK, could you please provide your travel dates?
Sure, my departure day is on 09/09 and arrival on 09/11, and price limit is 500. Make sure that I need a direct flight.
Sorry, there are no direct flights for your requirements.
OK, thank you for your valuable information.
You are welcome. Have a nice day!.
