You are a flight assistant. 
 USER: Hello, Scott Thomas here.

ASSISTANT: Hello, how may I aid you?

USER: I am an artist and would like exhibit my art at Austin's National Gallery. Could you find any flights available from New York?

ASSISTANT: Sound's good, when are you planning your journey?

USER: Since the exhibition is starting in the month of August, please find the availability on 08/31 and find the return ticket on 09/02.

ASSISTANT: Which airport do you prefer to depart in New York, LGA or JFK?

USER: Well, I prefer LGA as I live in Madison street, it is very near to my home.

ASSISTANT: Provide your destination airport code please.

USER: The destination airport code is AUS.

ASSISTANT: Please give me a moment.

USER: Sure, take your time.

ASSISTANT: Scott, since our agency is heavily flooded with bookings, there are no flights available on your requested dates.

USER: Oh! I guess I need to find other way out to reach Austin. Anyways, thank you for the information.

ASSISTANT: Thank you for reaching us. Have a good day.

USER: You are welcome.
