Hello.
Hello, How can I serve you?
I have to change the trip dates because my friend is unable to travel now with us, so we have postponed the trip. Can you please help me to modify the details?
Sure, May I know your name?
I am happy for your response. My name is Angela Gonzalez.
Please wait a minute.
Ok, take your time and let me know my ticket status.
Sorry, No reservation found on your name.
It's ok, not  a problem with that. Thank you for spending your time.
