Hi, my name is Susan and I need to find a flight from Detroit to Chicago.
On what day do you want the plane to arrive?
Sunday
Unfortunately there are no flights that match your search. Would you like to change any of your criteria?
I need a flight as soon as possible, is there anything available?
Right, I found an Economy flight with American for 481 credits
 that takes 8 hours to get to Chicago.
Wow that feels like a long time, hopefully the legroom is nice.
I also found an Economy flight with American for 358 credits that takes 6 hours to arrive at Chicago, leaving on the 29th.
I prefer the quicker flight on the 29th, can you please book that.
Sorry, but the flight with id '483' is not available any more.
ok, do you know what the weather will be like tomorrow in Chicago?
It will be Raining all day on Monday in Chicago, with temperatures of around 25 degrees celsius.
yuck, well i don't want the 8 hour flight but the 6 hour isn't available.
Would you like me to search for other flights?
nevermind, just book that first 8 hour flight
I'm sorry, but your reservation request was unsuccessful.
ok, well I need a flight from Detroit to Chicago, so can you book me one?
Right, your flight to Chicago on the 31st has been reserved!
thank you so much, have a good one.
Thank you and goodbye.
