Hi, myself Barbara Lopez.
Hello, how can I help you today?
I have to attend my friend's birthday party at Chicago, can you please help me to book the flight ticket from LAX to ORD?
Ok, please tell your travelling dates.
I will depart on 07/17 and also book the return ticket on 07/19.
Ok, please wait.
Sure.
Sorry to let you know but there is no flight available on your request.
No problem, thank you for the information.
You are most welcome.
