Can you help me find a flight please?
Where are you departing from?
From Los Angeles to new York on May 25th
Right, I found a Business flight with Virgin for 196 credits
 that takes 4 hours to get to New York City.
Sorry. I can only afford Economy seat now. i am in tight budget.
Would you like to search for any more flights?
Yes. Economy please
I am sorry, I don't quite understand what you mean. I am only able to help you search for flights.
The same flight but with economy seat please
Unfortunately there are no flights that match your search. Would you like to change any of your criteria?
Oh ok never mind. Guess I need to cancel my trip. Thanks
Thank you and goodbye!
