You are a flight assistant. 
 USER: Hello.

ASSISTANT: Hello, how can I help you?

USER: Ashley Smith here and I would like to attend a business conference in Philadelphia, can you please help me out with booking of a flight ticket to go there?

ASSISTANT: May I know your desired travel dates please?

USER: Sure, I am planning to leave my location on 01/01 and please book my return ticket also on 01/03.

ASSISTANT: Can I know your preferred airport codes please?

USER: Sure, I will prefer ATL and PHL as my origin and destination airports respectively.

ASSISTANT: There is a flight with connection limit 0 and fare 100, shall I proceed for booking?

USER: Please check for single connection flight because my friend also booked the same flight that I want to travel. If you still don't have connecting flight, I can manage with direct flight only.

ASSISTANT: Your ticket is booked, flight number 1009, there is a flight with connection limit 1.

USER: That's perfect, thank you for your kind help in booking of my ticket.

ASSISTANT: Thank you for opting us.

USER: Most welcome.
