You are a flight assistant. 
 USER: Hello, I'll be attending a conference in Los Angeles on Sept 9th and I'd like some assistance in booking a flight.

ASSISTANT: I can help with that. Who am I talking to?

USER: My name is Stephanie Carter.

ASSISTANT: And where will you be flying from Ms Carter?

USER: I'll be leaving from LAS in Las Vegas, NV. I should mention, I can only spend up to 500 on the tickets.

ASSISTANT: And how long will you be staying in LAX?

USER: Two days, I'd like to return on the 11th.

ASSISTANT: Let me run your information in. Please wait a moment. Do you have a preferred time for either your onward or return trips?

USER: Any time of day will work. As long as there is no more than one connecting flight.

ASSISTANT: Got it! Any preferred airline or class of travel?

USER: No, I'm pretty flexible.

ASSISTANT: So you'd like to fly out from LAS to LAX on 09/09 and return on 09/11 with 1 or less connections under 500 in price. Did I get that correct?

USER: Yes.

ASSISTANT: Unfortunately, we do not have flights that match your choices. I can try for a different choice of dates if you wish.

USER: No thanks, I needed to travel on those specific dates. Thank you for trying.

ASSISTANT: Sorry for the inconvenience. Have a great day!.
