Hi, I need to schedule a flight From Chicago to New York.
On what day do you want the plane to arrive?
I need to be there on May 11. Can you make sure I have a First class seat?
I can also filter the results for a specific airline, class, price or duration.
I don't have a preference for any of that. I'm not picky.
I don't have anything available in my system. Do you want to change the date or your preference?
Sure, that's fine. Is the next day available?
Unfortunately I don't have anything on the 12th but I found a seat on the 11th with business class. 
I guess I'll take it. Book the business class seat please.
Is there anything else that I can do for you?
No, that's it. Thank you.
Thank you and goodbye!
