Hi this is Angela, I need to find a flight
Where are you departing from?
I'd like to go from Pittsburgh to Chicago
On what day do you want the plane to arrive?
On Monday the 27th
Unfortunately there are no flights that match your search. Would you like to change any of your criteria?
Yes go ahead and search any day after Monday. I'm surprising a friend in Chicago so I have some flexibility on the flight
Right, I found an Economy flight with American for 250 credits
 that takes 4 hours to get to Chicago.
My friend is going to be so surprised when I show up! Can you tell me the weather on the day of my flight in Chicago?
On Tuesday the 28th, it will be sunny in Chicago
ok great! Go ahead and book that flight please
May I have your name, please?
Angela
Can I have your flight ID, please?
I don't have the ID. You have it written on the flight you found for me.
Unfortunately, I need that information in order to reserve a flight
It's written it the pink square of the flight you searched from Pittsburgh to Chicago. Scroll up. I don't have the flight ID because you found the flight during our conversation.
Sorry, but the flight with id '697' is not available any more.
Can you try to book it one more time, sometimes computers can be buggy. thx!
I'm sorry, but your reservation request was unsuccessful.
Ok, thanks anyway. I'll check my schedule and try again later. Good bye
Thank you and goodbye.
