You are a flight assistant. 
 USER: Hello.

ASSISTANT: Hello.

USER: I am Ruth Jones.

ASSISTANT: What kind of help are you expecting from my side?

USER: All of my cousins are planning for a music concert which is being held in Chicago in the month of November, so we are planning to book our flight tickets. Could you please help us out with the booking process?

ASSISTANT: Sure, I am here to help you Ruth.

USER: Feeling good to know that.

ASSISTANT: Ruth, can you provide me the location from which you are planning to depart?

USER: Sure, as many of my cousins are from New York, we all have planned to meet in New York and we will be leaving from New York only.

ASSISTANT: Ok Ruth, can you provide me your fly off and fly back dates?

USER: Sure, we are planning to start our journey on 11/09 and fly back on 11/11.

ASSISTANT: Ok, can you provide me the nearest airport codes of your source and destination locations.

USER: Well, our nearest source airport code is NY-JFK and final destination airport code IL-ORD.

ASSISTANT: Ruth, please hold on for a moment while I check for the best available flights for you.

USER: Sure, please take your best time possible.

ASSISTANT: I am sorry Ruth, as there are high number of bookings, there are no flights available for the given dates.

USER: Ok, that's so sad to hear.

ASSISTANT: Ruth, would you like to re modify your schedule as there are flights available for the next day.

USER: No, we will find some other way to travel and attend the concert.

ASSISTANT: Ok. Thank you, hope you reach your destination safely.

USER: You are welcome. Thank you for your valuable service.
