Hello my name is John
Hello, how can I help?
I'd like to search for a flight from NYC to Chicago
On what day do you want the plane to arrive?
Wednesday
Which day of the month would that be?
20th
Unfortunately there are no flights that match your search. Would you like to change any of your criteria?
21st
Right, I found a First flight with American for 222 credits
 that takes 4 hours to get to Chicago.
Sounds good
The flight is available. Should I reserve it for you?
Yes, please just as long as it's not Delta I'm good
The flight is on American, and thus I have reserved your flight.
Thank you
Is there anything else that I can do for you?
