Hello.
Hello, how can I help?
I'm curious about flights from Pittsburgh to Chicago.  Can you help me find one?
On what day do you want the plane to arrive?
I think it would probably be the 12th
There is a 7 am flight for 182 credits on United Airlines in Business class.
I need to go to Chicago to see my new niece.  I've sort of been putting it off but now I really need to go.
I can also filter the results for a specific airline, class, price or duration.
Are there any flights under $300 on that day?
Right, I found a Business flight with United for 182 credits
 that takes 6 hours to get to Chicago.
That would probably work.  Hey, what's the weather in Chicago right now anyway?
It will be Cloudy all day on Sunday in Chicago, with temperatures of around 30 degrees celsius.
Nice.  Hopefully it stays warm like that.  Actually, could you search again for a flight that's under $300 but that's not on United?  I can't stand United.
Unfortunately there are no flights that match your search. Would you like to change any of your criteria?
Yeah, raise the price to $500 and see if there's anything.  Just curious at this point.
Unfortunately there are no flights that match your search. Would you like to change any of your criteria?
No, that's fine.  But I do need to book a different flight. Can you book a ticket for me on flight id 301?
May I have your name, please?
Alexis
Sorry, but the flight with id '301' is not available any more.
Is 302 available?
The flight is available. Should I reserve it for you?
Yes please.
Right, your flight is now reserved!
Great, I've got some business I need to do.  Lots of flying these days.
Is there anything else that I can do for you?
No, that's it.  Thanks for the help.
Thank you and goodbye.
