Hey there, I need help in booking a flight to New York.
user
I can get that taken care of.  Could I get the name of the passenger?
assistant
Oh sure. It's David Thompson.
user
Thank you, Mr. Thompson.  Where will you be flying out of and which airport in New York do you wish to arrive at?
assistant
I will be flying out of Austin AUS to NY LGA airport. the dates would be departure on Aug 16th and return on Aug 18th.
user
I apologize, but there are no flights to LGA from Austin that day.  Is there anything else that I can help you with?
assistant
Not even for a normal-cost airline? my budget is around 5000 so cost is not a problem.
user
I'm sorry, but it looks like all flights are booked. Do you want me to put you on the waiting list in case a spot frees up?
assistant
Oh that would be great. Please put me on waiting list. I'll check back later.
user
Thank you for understanding.  One of our agents will get back to you if a seat frees up.  Have a nice day.
assistant
You too have a nice day.
