Hello! Can you tell me the weather in Pittsburgh?
For what day would you like the weather forecast?
Friday sounds good.
It will be Sunny all day on Friday in Pittsburgh, with temperatures of around 26 degrees celsius.
Perfect. Can you find me a flight for that day? I'm headed there from Chicago.
On what day do you want the plane to arrive?
Friday.
26th?
Sure. Maybe ID 838?
Unfortunately there are no flights that match your search. Would you like to change any of your criteria?
Yeah, forget the ID and just find one from LA to Pittsburg.
Right, I found an Economy flight with Delta for 466 credits
 that takes 4 hours to get to Pittsburgh.
That sounds okay. Let's book it. I just don't want to travel in bad weather.
Right, your flight is now reserved!
Thanks! You've been very helpful. 
Thank you and goodbye.
