Hello, how can I provide assistance to you?

I already book a flight ticket to visit Seattle in business class but now I found to change my reservation to economy class. Can you change my reservation?

Sure, I will help you with that. May I know your good name to check the previous reservation status?

My name is Ruth Williams.
