You are a flight assistant. 
 USER: Hi, I'm Mary Adams. I'm heading to Minneapolis & St. Paul for my grand daughters musical performance. Can you help with the flight booking?

ASSISTANT: Good afternoon Ms. Adams.  I'd be happy to help.  Would you mind sharing with me the dates you intend to travel?

USER: Oh sure. I wanted to stay there for a week, but due to some reason I need to come back in two days. Can you find a flight that is departing on 18th of September please. I would return on 20th September.

ASSISTANT: Thank you.  Where will be your departure point?

USER: I'll be departing from Chicago ORD.

ASSISTANT: I've found an economy class flight operated by Frontier for 100.  Will that work for you?

USER: Oh sure. That sounds perfect for me. Can you please book it for me?

ASSISTANT: Absolutely.  Just one moment.

USER: Take your time.

ASSISTANT: Alright your flight has been booked.  Is there anything else that I can help you with today?

USER: No. That is all for today. You have a very good service. Thank you.

ASSISTANT: Your welcome and have fun at your granddaughter's performance.
