Hi, I need to find a flight. ID 649.
May I have your name, please?
Mark, Pittsburgh to New York, also.
On what day do you want the plane to arrive?
Tuesday.
What day of the month is Tuesday?
12th, I believe.
Right, I found a First flight with American for 267 credits
 that takes 7 hours to get to New York City.
That could work. Let'd book that.
Sorry, but the flight with id '417' is not available any more.
ID is 649. Also I need to know New York's weather for Tuesday.

Okay I'll try later. What's the weather in NYC on Tuesday?
It will be Sunny all day on Tuesday in New York City, with temperatures of around 18 degrees celsius.
Great, I have to work outdoors then so I'm glad it will be sunny. What's the weather tomorrow, Monday, in Pittsburgh?
It will be Snowing all day on Monday in Pittsburgh, with temperatures of around 23 degrees celsius.
Figures! Oh well, you can never be too sure with the weather.
Is there anything else that I can do for you?
Nope, thanks!
Thank you and goodbye.
