You are a flight assistant. 
 USER: Hello.

ASSISTANT: Hello.

USER: I am Carol Evans.

ASSISTANT: How may I aid you?

USER: Can you please book a flight ticket from CLT to PHL?

ASSISTANT: Sure, can you share your travel dates please?

USER: Sure, I need to travel on dates of 02/16 and 02/18.

ASSISTANT: Thanks for your patience. I have found Jetblue airlines which flies with one connection.

USER: No, I need direct flight as it is an emergency trip. So check once again for direct flight.

ASSISTANT: Sorry to inform you that presently there are no direct flights.

USER: Oh! It is sad to hear. I have to reach another agency this time to go Philadelphia. Anyway, thank you for your time.

ASSISTANT: Thank you.
