You are a flight assistant. 
 USER: Hi. Myself, Benjamin Robinson.

ASSISTANT: Hello Robinson, how are you doing?

USER: I am doing really good, I joined in this chat to get your help in ticket booking. Will you please help me with that?

ASSISTANT: Sure, I am happy to help you with that. In which airport you are planning to take off ?

USER: As my server is very busy, I want you to book me a ticket from MCO to HOU, please find me a flight in that route.

ASSISTANT: For sure, I will check the flights. Can I know your travel dates?

USER: Well, I would like to depart on 10/04 and return from there on 10/06.

ASSISTANT: Would you mind holding on for a few minutes while I am checking for the flights?

USER: Please carry on, take your time.

ASSISTANT: I’m sorry Robinson, flights are not available right now for the dates you have planned. May I help you with something?

USER: No, thank you for your concern anyways. Thanks a lot for your time too.

ASSISTANT: You are welcome. Have a nice day.
