Hi
Is there anything else that I can do for you?
I need to find  a flight from Chicago to San Francisco for Monday.
On what day do you want the plane to arrive?
Monday and business class if possible.
what date?
14th
Unfortunately there are no flights that match your search. Would you like to change any of your criteria?
How about the 12th or 13th.
Right, I found a Business flight with Delta for 286 credits
 that takes 3 hours to get to San Francisco.
Great can you book that please.
May I have your name, please?
Angela
Sorry, but the flight with id '648' is not available any more.
I also need the weather forecast for San Francisco on Saturday 
It will be Raining all day on Saturday in San Francisco, with temperatures of around 18 degrees celsius.
Dang we're planning a picnic and don't want to get rained out. 
Is there anything else that I can do for you?
Can you also confirm a reservation on Flight 475 for my mom Alexis please?
