Hello! Good morning. 
Hello, how can I help?
I'm looking for a flight from San Francisco to New York City.
On what day do you want the plane to arrive?
Arrival on May 22nd please
Right, I found a Business flight with United for 426 credits
 that takes 7 hours to get to New York City.
Actually, I would like the flight to be on Delta. Is that available?
Right, I found a Business flight with Delta for 277 credits
 that takes 5 hours to get to New York City.
That sounds great, thanks!
Is there anything else that I can do for you?
That is all thank you
Thank you and goodbye!
