Hello
Hello, how can I help?
I am looking for a flight from Chicago to San Francisco
On what day do you want the plane to arrive?

Unfortunately there are no flights that match your search. Would you like to change any of your criteria?
Is there any the 29th?

What about Chicago to Oakland then?
There is a flight on the 30th.  It is 382 credits in First Class.  The arrival time is 2 am for 3 hours of flight.
Into Oakland?
No, San Francisco.
Okay great. Please book it.
I am sorry, I don't quite understand what you mean. I am only able to help you search for flights.
You don't have an option to book, only search?
Would you like to search for any more flights?
