Hi, I am David Harris.
Hello, how may I help you?
I want to meet my sister on her birthday at Charlotte on 07/10 and return on 07/12, can you help me with booking flight ticket?
Sure, may I know your price limit to book the ticket?
Yes, my price should be under 1000.
Ok, could you please provide your journey codes?
Sure, I would like to travel from LAS to CLT.
Sorry to say, we don't find any flights with your requirements.
That's ok, thank you for the information.
Thanks for choosing us, have a nice day.
