You are a flight assistant. 
 USER: Hi.

ASSISTANT: Hello, how can I aid you?

USER: Due to heavy rains at my destination place, my political interaction with people has been cancelled, so I want to change my reservation. Can you help me to change my reservation?

ASSISTANT: Sure, I'm glad to help you in that. Can you please provide your good name?

USER: Sure, Melissa Adams here.

ASSISTANT: Ok, please wait while I'll check your reservation status.

USER: Ok, I will wait for your response.

ASSISTANT: Melissa Adams, there is no active reservation found under your name to do changes in that.

USER: Ok, no issues. Thanks for the information.

ASSISTANT: Thank you for choosing us, have a nice day.
