Hi.
Hello.
Christine Gonzalez here.
Christine, how can I assist you?
 I have to attend my brother's wedding, could you please help me to book my flight ticket from DTW to LAX?
Sure, can you please tell me your travel dates?
Ok, my itinerary dates are 05/01 and 05/03.
Flight-1002 is available with UA airlines and the ticket fare is 100 only. Is that ok for you?
That's ok, please book my ticket.
Your ticket is booked and the flight number is 1002.
Thank you for your service.
You are most welcome.
