I have to get to San Francisco quick. I heard a rumor MLB is starting back up and I want to be there for opening day.
Where are you departing from?
I will be leaving from Pittsburgh. Never cared for the Pirates.
On what day do you want the plane to arrive?
Can you see if flight 115 is available? That's the one I took there last season.
May I have your name, please?
Susan
Sorry, but the flight with id '115' is not available any more.
Well crap. Can you check on it for me again? Sometimes the availability opens right back up. Maybe somebody will cancel.
You're right, There is a availability, would you like for me to book it now?
Yes, that would be great!
Right, your flight is now reserved!
Perfect! Maybe you can check the weather for me so I will know how to dress for the airport. What will the weather be on Thursday in Pittsburgh?
It will be Cloudy all day on Thursday in Pittsburgh, with temperatures of around 6 degrees celsius.
Not so great, but I guess I will deal. Can you tell me the weather for Los Angeles on Monday? I might drive out there in my rental and see if I can get on The Price Is Right. I love Drew Carey!
It will be Snowing all day on Monday in Los Angeles, with temperatures of around 23 degrees celsius.
That's crazy for this time of year! 
It is, is there anything else I can do for you?
No, I think that will be all for now. You know I will be back.
Thank you and goodbye.
