Hello, Rebecca Johnson here.
Hi. How Can I help you?
I would like to spend my weekend in Downtown in TX-IAH. So I want to book a ticket.
May I know your departure code?
I want to travel from LAS, travel dates are  04/09 to 04/11.
Rebecca Johnson, I am sorry I cannot find your reservation on your name.
It's ok, thanks for helping me out.
Thank you.
