Hello.
Hello, how can I be a help for you at this pleasant evening?
I planned a two days trip and reserved a plane ticket previously but in that plane ticket I need some modifications, please help me in that.
Sure, I will help you. May I know your good name please?
My good name is Brandon Roberts.
Sorry, there is no reservation found on your name to change the existing reservation.
I haven't expected this. Thank you for your response.
You are welcome.
