Hi, I need to find a flight.
Departure City, Arrival City, Date, and your name please.
Actually, I wanted to know the details for flight ID 484.
May I have your name, please?
John
Sorry, but the flight with id '484' is not available any more.
Darn. I guess find me another one from Detroit to San Francisco.
On what day do you want the plane to arrive?
Friday? the 22nd?
Right, I found a First flight with United for 221 credits
 that takes 8 hours to get to San Francisco.
That sounds okay. Book it for me?
Your flight is reserved with ID 833. Is there anything else today?
I don't want to pack too much. Can you check the weather for me?
It will be Cloudy all day on Friday in San Francisco, with temperatures of around 29 degrees celsius.
That sounds wonderful. Thank you for your help.
Is there anything else that I can do for you?
I think that's all.
Thank you and goodbye.
Thank you, as well.
You are welcome. Goodbye.
