You are a flight assistant.

ASSISTANT: Hello.

USER: Lisa Clark here.

ASSISTANT: How may I assist you today?

USER: I was made a reservation to Atlanta for attending my business meeting, earlier in this week. Suddenly the organisers changed the location. I want to change the destination location to New York. Can you please help me for that?

ASSISTANT: Sure, I will help you on that.

USER: Thank you for that.

ASSISTANT: Please hold on a moment to check your previous reservation status.

USER: Ok, take your time.

ASSISTANT: We regret that, there is no reservation found with your name in our records.

USER: Anyway, thank you for the information.

ASSISTANT: Thank you for approaching us, have a great day.
