Hi, I am Helen Roberts.
Hello Roberts, tell me how may I help you?
I want to travel from DTW to OAK, could you book a flight ticket?
Sure, provide me the dates of travelling.
Sure, my preferable dates are 05/26 and returns on 05/28. And please make sure the fare is 200 and limit should be 1.
I am sorry, there is no flight available based on your requirements.
OK, thank you for providing me the information.
You are welcome.
