Teacher: 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
Teacher: Now, understand the problem? If you are still confused, see the following 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: no_reservation
Reason: 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 instance: customer: Hello, my name is Jacob Turner. 
 agent: Hello, Jacob Turner, how can I aid you? 
 customer: I want to visit Space Needle, can you book me a flight ticket price under 500? 
 agent: Sure, I can help you with that. May I know your airport codes? 
 customer: Yes, I want to travel from Oakland, CA-OAK to Seattle, WA-SEA. 
 agent: To proceed further, we need your journey dates. 
 customer: Ok, I would like to travel from 06/01 to 06/03. 
 agent: Sure, Thanks for your details, please wait for a moment. 
 customer: Sure. 
 agent: Thanks for waiting, we found a Hawaiian plane of 1000 number. The fare is 500 with one connection. Can I proceed? 
 customer: Yes, please. 
 agent: Ok, your booking has been confirmed. 
 customer: Thank you for helping me. 
 agent: Thanks for connecting with us, have a safe journey.
