 USER: Hello, is this the CrowdCompute Travel Agency?

ASSISTANT: Yes, it is. How may I help you today?

USER: I need a flight to Las Vegas from Dallas. The airport codes are DFW and LAS, respectively.

ASSISTANT: Thank you for the specific codes. I'll check a flight for you. May i also know your travel dates please?

USER: November 30th, returning on December 2nd. Also, no connections on this trip. I broke my leg recently and find it hard to get from gate to gate within a time constraint.

ASSISTANT: Oh I hope you get well soon. I'll make sure you get a smooth flight.

USER: Thank you.

ASSISTANT: May I know what should be the name on the reservation?

USER: Please put it under Helen Wilson.

ASSISTANT: Good. Just give my system a moment to find an available flight.

USER: Alright.

ASSISTANT: Hey Helen, I'm so sorry to inform you that there is no direct flight going from Dallas to Las Vegas. All have atleast one connection in Chicago.

USER: Oh no. That's so disappointing.

ASSISTANT: I wish I could find you a direct flight. I apologize again for this. Hope we can help you next time.

USER: No need to, you can't control what flights airlines offer. Thank you for your help today!.

ASSISTANT: Take care.
