Hi.
user
Hello. How can I aid you today?
assistant
I would like to prefer a economy class flight for my holiday trip to Oakland. So can you book a flight ticket for me?
user
Sure, I am happy to help you with the ticket booking. Could you please tell me the airport codes of your desired locations.
assistant
The airport codes are from LGA to OAK.
user
Ok, on which dates you are looking to book a flight ticket?
assistant
My trip dates are from July 05 to July 07. Sorry Instead of economy class look for a business class.
user
Sure, I will check for that. Is there any other specifications?
assistant
I need a single connecting flight.
user
I regret to inform you that, there is no flight available in the business class in this route.
assistant
Not a problem. Thank you.
user
You are most welcome. Have a nice day.
