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: Hi. 
 agent: Hello. How may I help you? 
 customer: I am Helen Perez here, I want to reserve my ticket from IAH to LAX, can you please help me out? 
 agent: Sure, I am gleeful to help you. Could you please provide your travelling dates to search for the flight? 
 customer: Sure, my dates of journey are from Jul, 27 to Jul, 29. 
 agent: May I know your connection limit? 
 customer: Yes, I need a connecting flight. 
 agent: Do you have any other specifications? 
 customer: Yes, I need a depart time at morning. 
 agent: Here I found a connecting flight-1024 in economy class. Shall I proceed? 
 customer: Ok, please proceed. 
 agent: Ok, booking is done on JetBlue airlines.
