In this task, you are given a conversation between a flight agent and the customer. You are given 4 options and you need to select the goal of the conversation. It is provided as part of customer's context, which has to be one of the following: `book`: Make a new reservation, `cancel`: Cancel an existing reservation, `no_flight`: No flight found for the customer's preference, `no_reservation`: No reservation / No change / No cancellation was made in the conversation, mostly enquiring details
One example: customer: Hi. 
 agent: Hello. How can I help you? 
 customer: I would like to change my existing reservation as my plan to go for a holiday trip got postponed. Can you please help me with this? 
 agent: Sure, may I know your name please? 
 customer: My name is Anthony Phillips. 
 agent: Please wait a moment. 
 customer: Sure. 
 agent: Unfortunately there is no reservation found with your given name. 
 customer: Not a problem, thank you for checking. 
 agent: Thank you for choosing us.
Solution is here: no_reservation
Explanation: Here the customer has not asked for any booking, he just wanted to update his already booked flight, so the status would be no_reservation

Now, solve this: customer: Hello. 
 agent: Hello, how may I assist you? 
 customer: I am Scott White, find a flight from New York NY-LGA to attend a family meeting at my uncle place. 
 agent: White, may I know your full journey details. 
 customer: My destination airport is Las Vegas,NV-LAS. My return ticket is on 02/01. My date of journey for depart is 01/30. 
 agent: Glad to say that we had found a flight with the airline JetBlue and the flight number is 1004. Can I proceed? 
 customer: Sure. 
 agent: Your reservation is done. 
 customer: Thank you for helping me. 
 agent: Thank you White, have a nice day.
