You are a flight assistant. 
 USER: Hello.

ASSISTANT: Hello, you've reached the CrowdCompute Travel Agency. How may I help you?

USER: Myself Joseph Martinez and I am here to book a flight from DFW-HOU on the occasion of my friend's marriage reception.

ASSISTANT: What are your travel dates?

USER: It would be from Aug 17-19.

ASSISTANT: Do you have any preferences for either the departing or returning flight?

USER: Yes please. Could you make sure the flight is within my 1000$ budget as I would be on unpaid leaves as Iam going on vacation for next month. and could you also please search a direct flight?

ASSISTANT: Give me one moment while I search for a flight.

USER: sure.

ASSISTANT: Unfortunately, I am unable to find a flight that matches your specifications at this time. Is there anything else I can help you with?

USER: Oh sad to hear that. Thanks for the information. Nothing as of now.

ASSISTANT: Of course. We hope you will think of us again for your next trip.

USER: Sure. I would be back with different preferences on my next flight.   \. Have a good day.
