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

Let me give you an 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.
The answer to this example can be: no_reservation
Here is why: 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

OK. solve this:
customer: Hello. I am Raymond Thompson. 
 agent: Hello, how may I support you today? 
 customer: I got an invitation for Pasadena Strawberry festival from my step mom, can you help me to book a flight ticket to Seattle, within the price of 200? 
 agent: Sure, we are here to help you. May I know your connection limit? 
 customer: I need a connected flight. 
 agent: Could you please provide your travelling days? 
 customer: I want to start my journey on 08/07 and return at 08/09. 
 agent: To move for booking we need your airport codes. 
 customer: My airport codes are: PHX and SEA. 
 agent: Please wait for a while. 
 customer: Ok. 
 agent: Thank you for your time. We found a flight 1002 in Jet Blue and with a price limit 100. It is a single connection flight. Shall I proceed with this flight? 
 customer: Perfect, Please proceed with this airline. 
 agent: Thank you for making us to serve you, your ticket has been confirmed.
