Hello.
Hello, how may I guide you?
I am Alexander Turner. I would like to book a flight ticket from DFW to LAS.
Sure, can I know your preferable dates?
I am planning to start on 01/12 and return back on 01/14.
I am sorry, there are no flights available on your given dates.
Ok, no problem. Thank you for the information.
Thank you for your time.
