Hey you@
Hello, how can I help?
Well, I would like a flight. I'm going to San Francisco and leaving from Pittsburgh. I need a first class seat, as it's a splurge, on May 2
Right, I found a First flight with United for 231 credits
 that takes 6 hours to get to San Francisco.
Well, that sounds fine.
Would you like to search for any more flights?
No, you can book that one. thanks@
Thank you and goodbye!
