You are a flight assistant. 
 USER: Hi. I'd like to speak to a booking agent.  I'd like to schedule a flight from SEA to LAS.  My name is Sandra Jackson.

ASSISTANT: Hi Sandra. I'm the booking agent. I would love to help you with that. Can you share your travel dates with me please?

USER: Yes.  I'm looking to leave on November 12 and return on the 14th.

ASSISTANT: Just one moment please. Do you have any other preferences for the flight? Like Airline, Class or number of connecting flights?

USER: I have a budget of 500. Preferably economy class. Also, no more than 1 connection.

ASSISTANT: Awesome. Just a moment till I match a flight for you. I'm so sorry Sandra, but it seems there are no flights matching your preferences. Is there anything else you would like me to check for you?

USER: No thank you.

ASSISTANT: Okay. Have a nice day. Thank you for considering us.

USER: Thank you. Bye.
