Hello, I am Melissa Hernandez.
Hello Melissa, how may I assist you?
As my manager did not approve my leave, I would like to cancel my recent reservation.
Sure, I am here to help you. Hold on for a moment. Let me check.
Sure, take your time.
Sorry Melissa, there are no flights reserved on your given name.
That's ok, thank you for checking.
Welcome, thank you for choosing us. Have a great day.
