Hello
Hello, how can I help?
I need a flight from Pittsburgh to New York City for May 30th.  Economy.  I'm cheap.
Right, I found an Economy flight with Delta for 431 credits
 that takes 6 hours to get to New York City.
Do you know what time that flights takes off and lands?
You will arrive at your destination at 7am.
Is it non-stop?
I'm sorry, I don't have that information.
OK  I'm not crazy about red-eyes, but cheapos can't be choosers.  Book it.
Would you like to search for any more flights?
No, that will do.  I have an early morning meeting.
I cannot book the flight.  I can only find one for you.
I see. OK.  I'll go on the ailrline's website.
Thank you and goodbye!
