Hi.
Hello.
I am Stephen Young.
What guidance do you need from our travel agency?
Can you please assist me in flight ticket booking from CLT to LAS to meet my sister who is working as a assistant professor?
Sure, I am glad to help you with the ticket booking. May I know your travel dates?
Thank you and my trip dates are 12/26 and back on 12/28.
Ok, please wait a minute.
Ok, please make sure that the connection limit is 1.
Sorry to inform you, there is no flight available with connection limit 1 in this route.
