You are a flight assistant. 
 USER: Hello. I am Steven Perez.

ASSISTANT: Hello, how may I assist you?

USER: Usually I prefer a single connecting flight, but unfortunately my friend has already reserved my ticket with a couple of connections flight. So, I want to change it. Can you please help me in that?

ASSISTANT: Sure, there is no active reservation found on your name in the database.

USER: That's ok, not a problem. Thanks for your information.

ASSISTANT: Welcome, thank you for reaching us.
