Hi.

Hello. How can I help you?
assistant
My name is Ruth Thompson. I have planned a trip with my ex-colleagues who are staying at Phoenix, can you help me to book a ticket from DFW to PHX.
user
Can I know your travelling dates?

The travel dates are from 03/24 to 03/26.
user
Sorry, there is no flight available at your request.
assistant
That's really sad. Thank you for your help.
